Izuku Midoriya/Relationships

Inko Midoriya
Inko is Izuku's mother, and she cares deeply for him; when her son finds out he's Quirkless and therefore cannot be a hero, she apologizes profusely as if it were her fault. It is hinted that she blames his sadness on herself and has gained weight as a result, but it is unknown if this is true.

However, once Izuku receives his new Quirk, One For All, and gets into his dream school, U.A. High School, she is happy for his newfound powers, but feels guilty about her former beliefs. Inko tries to make it up to him and show her support by creating a costume for Izuku, using the design she had seen him sketch. She brings up her past actions and apologizes for not believing that he could be a hero, reassuring Izuku that she will support him all the way on his path to accomplish his dream; Izuku is touched by this and thanks her.

Despite these words of encouragement, it is evident that Inko becomes worried for Izuku when she sees the distressing amount of damage done to his body after he used his new Quirk. Indeed, after the ordeal at the training camp, Inko is completely against him resuming his studies at U.A. due to the staff's inability to properly protect her son. Izuku is shocked at this and cannot seem to say anything to shift mother's firm stance. Only after Izuku shows her Kota's letter, a sign that he is truly on the path to being a hero, does she change her mind about U.A.. She also makes All Might promise to take care of him, and stay alive for him.

While upgrading his costume, Izuku only adds a few things on it and refuses to modify it even further as he is attached to it. He appreciates that his mother made it for him and he wants to keep it as a reminder that she is supporting him.

During their brief reunion for New Years, Izuku lets her know of his predicament with his powers and, while she is worried, Inko is proud of him for saving Eri.

As of the breakout at Tartarus, Inko is aware of the nature of Izuku's acquired Quirk, One For All.

Hisashi Midoriya
Hisashi is his father but he has not been seen much in either his or his wife's life, as his whereabouts and status are unknown. It is unknown if Izuku had a stable relations with Hisashi considering that he was absent for most of the time. All that is known about him is that he took a work post abroad and that his Quirk allows him to breathe fire.

All Might
Izuku has always admired All Might and strives to become a hero just like he used to be. In their first meeting, All Might saves Izuku from the Sludge Villain and signs the happy boy's notebook. However, Izuku is very shocked to see All Might's true form and is dismayed when the latter tells him being powerless does not fare well at all for his chances at becoming a hero. Despite this, Izuku earns All Might's respect after he runs toward the slime monster in an attempt to save Katsuki, and a mentor-student relationship blooms between the two when All Might chooses him as his successor. While All Might's training on Izuku is rough, he continues to give it his all in the hopes of achieving his dream. They grow closer when All Might listens to his resolve of training and doing more than he has to become a great hero, impressing the hero.

All Might is Izuku's confidante, mentor, and friend in and out of school, and they share a mutual respect for each other's heroism ideals. All Might returns Izuku's admiration by telling him that he was formerly Quirkless before he was given One For All. All Might is also impressed by how much Izuku has improved his Quirk after his time with Gran Torino, and deems it is time to tell Izuku of their Quirk's history.

Izuku's admiration and respect for All Might are so great that he avoids attacking All Might during the First Term Final Exam, but when it turns out he has no choice but to attack him with one of Katsuki's Grenadier Bracers, Izuku apologizes in advance.

At first, Izuku is an extreme fanatic who tries to imitate All Might from his style of name and costume design. As he matures, later on, Izuku slowly learns to become his own hero and develop his own style. This change is noticed by All Might, who is proud to see Izuku on his way of becoming his own hero, improving his unique skill and style.

Izuku has an almost father-and-son-like relationship with All Might, treating him as a father figure, demanding his respect and the truth from him during times where All Might would rather preserve Izuku's focus on becoming a hero. After the breakout from Tartarus, All Might has taken to supporting Izuku during the boy's vigilante activities, with Izuku keeping his distance from others to avoid All For One homing in on him through the connection between their Quirks.

Unfortunately, after his battle with Lady Nagant and All For One's message to him that "it's his turn", Izuku keeping his distance from All Might as a result of the overwhelming pressure to keep his family and friends safe, and ultimately leaves him behind to go off on his own against All Might's objections. However, after his classmates snap him back to his senses and bring him back to U.A., Izuku's relationship with All Might reverts back to normal, with Izuku apologizing to All Might for his cold behavior and thanking him for helping him as much as he could.

Recovery Girl
Recovery Girl is one of the few people who know about Izuku's Quirk. She often scolds Izuku for using his Quirk dangerously, as he consistently requires the use of her healing Quirk.

After the U.A. Sports Festival, Recovery Girl reaches her breaking point. Fearing that he will continue to cause serious harm to himself as long as he thinks he can just be healed by her, Recovery Girl refuses to heal Izuku's self-inflicted Quirk injuries.

Shota Aizawa
Shota is Izuku's homeroom teacher. Initially, Izuku does not recognize him as a pro-hero and was put off by his deadpan manner. This lasted until the latter uses his Erasure Quirk to restrain him, which causes Izuku to remember he is Eraser Head, a pro-hero that he respects for his power and capabilities. At first, Shota firmly does not believe Izuku can be a hero due to his reckless behavior when using his Quirk, as he would be useless in battle if he kept getting injured. However, Izuku proves to Shota that he has potential; the latter is extremely impressed and sees Izuku's potential in becoming a pro-hero.

Throughout the series, their relationship can be defined as a rocky, troublesome student-teacher relationship. As his teacher, Izuku listens to Shota's orders and advice in order to improve himself. He has some level of respect towards Shota, as he is surprised at the latter handling several villains by himself. However, Shota's cold and logical personality conflicts with Izuku's own, making it difficult for the two to get along. Out of all his students, the exception being Katsuki, Shota appears to antagonize Izuku the most whenever he does something that upsets him, a recurring problem being Izuku overusing his Quirk and breaking his body. As such, Shota refers to Izuku as the 'Problem Child'.

However, Shota is still Izuku's teacher and as such, ultimately cares for him. He offers some level of consolation and guidance for Izuku when he is upset, and he will make sure Izuku does not do anything dangerous and act upon it. In return, Izuku once tries to help Shota when he decides to fight off several members of the League of Villains and is amazed by his abilities since he realizes he greatly underestimated his teacher. However, he is horrified to watch him being overpowered by Nomu at the Unforeseen Simulation Joint. This shows the more caring and inspirational side of Shota helps Izuku get along better with him. Izuku also carries his teacher to safety after All Might appears.

It is possible another reason they sometimes do not get along well is because of Izuku's personality and mindset bearing similarity to All Might's, who Izuku looks up to. Shota and All Might do not get along, and this is extremely evident in Shota and Izuku's relationship.

When Izuku appears to him injured after his battle with Muscular, Shota immediately wants to scold him for being reckless but sees that he only got wounded to protect Kota. He also scolds Izuku for joining in the rescue of Katsuki, which put him in danger.

Regardless, Shota encourages him in the mission to rescue Eri, something that causes Izuku to see that he wants him to atone for betraying his trust.

Recently, Shota has taken note of Izuku's Quirk gradually changing and asking him on the phenomenon and gets a vague answer.

During the Paranormal Liberation War, when Tomura targets Eraser Head to stop his Erasure Quirk, Deku stops Tomura alongside Katsuki. While holding him back, Deku exclaims that contrary to what Gran Torino said that losing One For All being the worst-case scenario, losing his teacher who had always looked out for him would be so, he refusing to stand back while his life is on the line; these words touch Eraser Head, and make him more determined to stop Tomura Shigaraki.

Class 1-A
Izuku has formed positive relationships with most of Class 1-A due to his kindness, bravery, and intelligence. He cares about them all dearly, and vice-versa. As seen in the Provisional Hero License Exam, his emerging leadership skills play a key role in his class' victory against the other schools. This also shows that almost all of his classmates are willing to listen and follow his lead, even those he casually knows respect him enough to follow him. It has been shown that part of Katsuki's anger and jealousy toward Izuku is over how popular he is with the rest of the class.

Izuku's classmates clearly think well of him and have come to see Izuku as a leading figure, despite his initial shyness and the difficulties he had with his Quirk. During the events of My Hero Academia: World Heroes' Mission, when Izuku was (falsely) placed as a suspect on the run for mass murder, all of his classmates refused to believe that he could have done something so terrible.

Following the Paranormal Liberation War, Izuku put enough trust in his classmates to reveal the truth about his Quirk and the reason he'd be targeted by Tomura and All For One through letters sent to all of his classmates before leaving U.A. High to protect them from potential attacks. While he is fighting hired villains, he thinks about all of his classmates and hopes to smile with all of them once he's done. However, Izuku is displeased when Class 1-A comes to save him, exposing themselves to the danger he tried to protect them from. So, he tells them to get out of his way, sparking a conflict between him and his friends. During the fight, Class 1-A reminds Izuku of all the times that he had said and done for them, showing how much they really care about him.

Katsuki Bakugo
Izuku and Katsuki have known each other since early childhood, but their relationship appears to have deteriorated over the years. Ever since he fails to develop a Quirk as a child while Katsuki does, he has seen Izuku as weak and constantly bullies him, giving him the derogatory nickname "Deku", which stems from "Dekunobou" or "someone who can't do anything": a nickname he always refers to him by. In the dub, however, the explanation for the nickname is shortening of "defenseless Izuku". Interestingly enough, Izuku returns the favor by calling Katsuki his childhood nickname, "Kacchan".

While Katsuki attempts to struggle his way out of the Sludge Villain's grasp, Izuku surprises him by rushing to his aid. Much later, Katsuki catches up with him and berates him for his actions, calling him a Quirkless failure, most likely out of pride. Izuku's heroic act is also what causes All Might to choose him as his successor of One For All, thus making Katsuki indirectly responsible for his acceptance into U.A..

Izuku stands up to Katsuki and enrolls in U.A.. He also reveals his new Quirk, with Katsuki reacting in surprise as the latter angrily questions if Izuku intentionally hid his powers from him. In a training battle, Katsuki attacks Izuku, but once again Izuku surprises Katsuki by revealing he has been memorizing his moves and knows how to counter them, as he once possesses a strategy book that details all of Katsuki and other's moves before Katsuki burns it. Finally standing his ground against Katsuki, Izuku tells him that he is no longer the same kid Katsuki used to bully, even stating he will use the nickname Katsuki gave him as inspiration. Enraged by Izuku's bold claims, Katsuki attacks relentlessly to get him to use his Quirk, which works but ends with Izuku defeating him for once. After the exercise, Izuku catches up to Katsuki and tells him he obtained his powers from someone else, but Katsuki seemingly does not believe it and swears to defeat him.

Izuku states that Katsuki makes all of Izuku's insecurities about himself bubble to the surface. Despite their strained relationship, Izuku still admires him for his strong Quirk, natural combat capabilities, confidence, and his ability to win. Since the end of the Battle Trial Arc, Izuku has not spoken to Katsuki on friendly terms due to Katsuki considering Izuku his arch-rival. Izuku is also surprised to see Katsuki is the one being teased by their class, a complete reversal of their middle school days. Even still, Izuku maintains respect for Katsuki and is shown to care for him, as shown when he tried to ensure Katsuki's safety from the villain attack. Despite Izuku's best efforts, Katsuki is still captured by the Vanguard Action Squad, so Izuku uses all his strength in an attempt to save him and spirals into despair after he fails to do so. Directly after, Izuku teams up with Tenya, Eijiro, Shoto, and Momo in an attempt to rescue Katsuki from the League of Villains' hideout.

Back at U.A. sometime later, Katsuki remarks to Izuku that he is really making his borrowed power his, revealing he believes Izuku's story of obtaining a Quirk, which worries Izuku.

Later on, Katsuki and Izuku take out their stress on each other in an emotional fight, which Katsuki wins. After the fight, Katsuki learns the full truth of Izuku's Quirk and his connection to All Might, which he seems to understand and decides to keep the secret to himself.

Unbeknownst to him or Katsuki, Shota has seen their bond having a big effect on the rest of the Class 1A despite that they are not leaders or the most popular. Izuku and Katsuki's passion inspire everyone in the class and raises the standard for success.

Since then, the two better understand each other and have become more reminiscent of that of a proper "friendly" rivalry, although they still have a long way to go. Katsuki is willing to work with Izuku and be less malicious towards him. He willingly fought alongside Izuku who temporarily gave him One for All. When Izuku temporarily gave it to him, they thought that the action would end Izuku's dream and that he was going to be Quirkless again. Together, they were able to defeat Nine. In the end, both of them talked to each other and were smiling, showing that their fierce rivalry gradually becoming more friendly.

The two have shown to be at a recovery period in their relationship. They're allies in battle, and support as well as challenge each others' strengths in weaknesses. Their core fundamentals being that Katsuki wants to win while Izuku wants to save. All Might encourages both of their philosophies as well as their mending friendship. Katsuki has yet to apologize, and both him and Izuku have yet to reach a comfortable stage of their friendship where they refer to each other as friends. Their dynamic has seen the most growth and significance in the series, having a movie centering around their team-up, and dynamic duo titles such as "the Wonder Duo", and "Twin Stars".

In the Paranormal Liberation War Arc, Katsuki went along with Izuku and protected him, showing that Katsuki does care for him. Although he doesn't admit it, he does show some level of respect for him and considers him his true rival for the number one hero spot. When Deku's life was in peril as Tomura launched Rivet Stab at him, Katsuki rises up and is injured by the attack. Deku, already enraged up from all the wrongs Tomura had committed, turns to a feral state.

Later on, during the Dark Hero Arc, Izuku starts to become exhausted from all the stress and burden. Dictator uses his Quirk to send a mob of citizens to attack Izuku. However, Katsuki actively saves Izuku from Dictator using AP Shot to defeat him and freeing all the citizens.

After Tenya successfully retrieves Izuku, Katsuki confesses that his body moved on it's own to save Izuku, the true nature of his bullying before calling him by his real name and apologizing for his prior bullying. Even after moving back to the Height's Alliance, their relationship has hardly change when it comes to becoming the no. 1 Hero. Izuku and Katsuki continues to have a stable respect for one another, and in the beginning of the Final War, Izuku and Katsuki continues to work together for the final battle against All For One and Tomura. However, Izuku was caught in in a trap by Himiko which dragged him to a different portal created by Monoma.

After Izuku escaped from Okuto Island, he was generally worried about Katsuki and the other classmates until he returns to the U.A Flying Sky Fortress. Upon arriving, he was devastated when he found Katsuki's corpse, having to be killed by Tomura, causing him to go into shock. Seeing all the other barely conscious Heroes sends Izuku into a further induced stress, while "Tomura" mocks him for his tardiness. With his fear realized about Katsuki's death, his stress turned into rage which once again overwhelm Izuku as his Quirks begin to spiral out of control until Mirio Togata reappears to Izuku. He attempts to talk some sense into him, telling him that everyone is still breathing and that Edgeshot is saving Katsuki's life, so they need to keep on fighting because they haven't lost anyone yet.

It was right then that Izuku calms his nerves and entrusts his hopes to Edgeshot to revive Katsuki while he engages Tomura in a fated battle.

Ochaco Uraraka
Ochaco is the first person that Izuku interacted with at U.A. High School. He saved her from being attacked by a giant robot and she returned the favor by ensuring he landed safely on the ground after jumping to her rescue. The two met again after becoming classmates and soon became close best friends; they get along very well and their discussions are always bright and friendly. A running gag is Izuku blushing and getting flustered whenever Ochaco happens to be too close to him, hinting that he might have a crush on her. Ochaco is the one who turned his once demeaning nickname "Deku" into a positive identity for him, saying it gave her a "never gives up" vibe. They share similar ways of quick thinking, tenacity, perseverance, and high spirit, which contributes to their friendship.

They mutually respect each other, as Ochaco is inspired by Izuku, striving for his level of tenacity and perseverance. They are protective of one another, as Ochaco quickly called the police after she found Tomura threatening Izuku. Izuku thinks of her as a brave and resourceful person by herself and considers her very capable of devising strategic plans on her own. He even defends her from Katsuki when he thought she was incapable of fighting on her own and had help from Izuku.

Another example of his confidence in Ochaco is seen during the Provisional Hero License Exam. Himiko Toga (disguised as Camie Utsushimi) used her Quirk to impersonate Ochaco, but Izuku saw right through her disguise, as "Ochaco" jumped into danger without a plan, something he knew that the real Ochaco would never do. When Himiko sees Ochaco, she tells her that Izuku trusts her immensely.

When they first met, Izuku was unable to hold a conversation with her, due to his timidity towards girls, but as he gets to know her more he is able to speak confidently with her, but still sometimes blushes when she stands too close to him.

Over time, Ochaco has developed a crush on Izuku. And while not outright confirmed, it's hinted that Izuku reciprocates her feelings. For example, he felt immensely touched when Ochaco turned his nickname "Deku" into a positive identity for him, that inspired him to choose it as his official hero name. He also confidently defended Ochaco from Katsuki when the latter thought she fought him valiantly only because she had guidance from Izuku. Other small interactions like being flustered when caught by Ochaco touring I-Island with Melissa Shield further supports this, along with growing tenderly concerned for her during their battle against Nine on Nabu Island. While participating in a joint training exercise with 1-B, when Izuku was first manifesting Blackwhip, Ochaco was the first to realize he couldn't control it and came to his aid. After, she showed was concerned for his well-being. His reckless regard for himself had lead to her understanding heroes need protecting too, and she makes a vow to watch out for anybody who needs it as a hero who saves people to help them and not just for money. He would also inspire her to add hooks to her gauntlets for rescue a while later.

Afterward, at Christmas, she and Izuku receive each other's Secret Santa gifts with ecstatic looks on their faces. Ochaco got Izuku a bag of Mochi Chips, and Izuku got her an All Might keychain. Ochaco has taken to carrying this keychain he gave her on her belt, causing Mina to tease her. But at that time, Ochaco smiled and responded in a slightly nervous way while putting the keychain away, indicating that she felt a little less embarrassed about her feelings for Izuku. After starting up work studies again, Class 1-A showed off their new moves to All Might. Ochaco and Izuku shared a touching moment where they thank each other for making one another stronger, fist-bumping.

During the Paranormal Liberation War, when Izuku broke off from the group and decided to go off on his own alongside Katsuki, Ochaco watches him go off while feeling concerned about him. After the battle, when Izuku fell into a coma, Kyoka asked if Izuku was alright, in which Ochaco responded that she feels worried as she stood in front of the door of his hospital room. While Izuku continued conversing with the predecessors while unconscious, All Might left the room, and Ochaco was the first person to go in to check on him. Back at Heights Alliance in April, Ochaco and her classmates received individual letters from Izuku. Her letter said how Izuku thanks her for everything, confessing the truth behind his Quirk: that he received it from All Might, how All For One and Tomura are after him, and that he must leave because of it. After she read her letter, she calls him a dummy for his rash decision making, deeply worried.

She later joins the rest of 1-A in tracking him down to bring him back to U.A. When it's Ochaco's turn to speak with him, she explains she and the others are more than willing to go after Izuku even though she understands he's only trying to keep them safe. Before Ochaco can finish her sentence, Izuku tries to run away. Ochaco gathered her classmates to launch Ida after Izuku to capture him, thinking to herself how she knows that she and everyone has something to say to him but they know their words alone won't have any effect. She acknowledges the class don't want to be protected by Izuku, or that they're rejecting Izuku's own beliefs and his actions. She and the others just want to be with him. When the class succeed in rescuing Izuku, they bring him back to school. Yet as he suspects, the civilians refuse to let him inside. They know he's the rumored boy Tomura was pursuing. After they were convinced U.A. would provide them sanctuary, they're scared about allowing in what they consider a "ticking time-bomb". Izuku is about to leave but Ochaco grabs his hand to stop him and tells him it's okay, as she is determined to not let him go.

She shouts down the crowd on behalf of Izuku and everybody's sakes, firmly rebutting every criticism thrown against him and the heroes with compassion and logic. Izuku, deeply moved, is reduced to tears and kneels before her, incredibly thankful for her passionate defense of him. Thanks to her speech, Izuku is allowed inside and is able to rest properly for the first time in weeks.

After shacking up at the dorms, Izuku asks where Ochaco is and wants to thank her personally, but she already went to sleep because the day's events had exhausted her. Then Cathleen Bate buys the heroes of Japan time to regroup and track down the villains with her sacrifice against Tomura and All For One. And then the reveal of Aoyama being a spy for All For One also puts a great strain on the class dynamic as they zero in on destroying the diabolical mastermind for good, making things far too busy as everybody prepares for a second war.

Ultimately, it would take another week of waiting for Izuku to finally get the chance to speak to Ochaco personally at Class 1-A's new mobile stronghold, Troy. He meets her on the cliffs overlooking the damaged cityscape the day before the operation against All For One, thanking her profusely for what she did. This makes Ochaco embarrassed as he keeps showering her in compliments, and when she calls herself weird Izuku rambles about how pretty her hair looks making her further flustered. They then get to discussing Himiko, with Ochaco relating that she held complicated feelings toward the serial killer, but realized it wasn't fair to judge her too harshly since she knew nothing about her. She makes it clear she can never forgive her, but she's thinking about reaching out and attempting to save her all the same.

Izuku is pleasantly surprised to hear this, as he himself holds similar feelings toward Tomura. He explains he felt the presence of a little boy inside him and wants to save him if possible. Ochaco chuckles and remarks "both of us are kind of weird". They spend some more time together in silence, surveying the damaged city as they wait out the final hours before their upcoming confrontation with All For One and the rest of the League, knowing it'll be the fight of their lives.

Tenya Ida
In their first meeting, Tenya labeled Izuku's muttering about heroes as a distraction and thought he would be a hindrance to the school which earned Izuku bad attention from his peers. However, in the entrance tests, Izuku surprised Tenya by selflessly going back to save Ochaco and using his Quirk to destroy a giant robot in the process.

When they met again in class, Izuku first thought that Tenya was scary and that they wouldn't get along, but was surprised as the latter apologized for his previous treatment to him and even considered Izuku better than him in many ways after the entrance course, much to Izuku's shock. Izuku got to know Tenya better, where he found out that while the latter was serious he was also kind and they ended up becoming friends. Izuku and Tenya are usually friendly with each other. However, sometimes their friendship slightly falters such as when Izuku criticized Tenya for seeking revenge against Stain and Tenya punching Izuku in the face for acting recklessly by attempting to save Katsuki. Tenya has often compared Izuku to his brother, for whom he has great admiration for.

Despite this, Izuku and Tenya's friendship has rebounded back many times despite these mishaps, mainly because they are only concerned for each other's well being. They are usually seen together having friendly discussions. Izuku resigned as Class President and named Tenya as his successor, knowing that he has better leadership qualities than him. After Tenya is defeated by Shoto, Izuku is saddened to see his friend lose. Since Izuku knows that Tenya has a grudge against Stain, he tries to save him from his death. While recuperating at Hosu General Hospital, both Izuku and Tenya resolve to become stronger together.

During the climax of the battle when Class 1-A combines their powers to catch up to Izuku, Tenya gets launched and grabs Izuku's hand. Tenya would say that Ingenium is the Hero who will grab the hand of a lost child and that giving help that's not asked for, is what makes a true Hero, paralleling Izuku's words to Tenya that meddling where you don't need to is the essence of being a Hero. These words would cause Izuku to openly break into tears upon hearing those words.

Shoto Todoroki
Shoto originally saw Izuku as his arch-rival, due to him having connections with All Might (a person with whom his father has a major rivalry with). Izuku, on the other hand, has always held great respect for Shoto, admitting that he is far stronger than him. Shoto confronts Izuku at the U.A. Sports Festival, asking if he is All Might's secret love child, but the latter denies this as Shoto decides to reveal his family history. After hearing Shoto's tragic backstory and seeing his sadness, Izuku starts to show sympathy for the pain he went through and resolves to help him overcome his dark past by getting him to use his power, telling Shoto that the power is his own and not his father's. Although Izuku loses to Shoto while trying to help him, Izuku's actions do have an impact as Shoto starts reacquainting himself with parts of his past he had forgotten and stops rejecting his power. Shoto also recognizes that Izuku knowingly insisted on helping him, despite knowing it would lead to Shoto's victory.

Shoto even comes to his aid when Izuku and Tenya are attacked by Stain, telling his father he was going to "help a friend" when he received Izuku's location. They work well together, going on to defeat the infamous hero killer. After the battle, Izuku and Shoto are on friendly terms with each other, with Izuku even laughing at Shoto's expense when he was worried that he was cursed to always hurt people's hands. They are good friends thereafter — Shoto, who was previously shown to have little interactions with his classmates, starts to hang around with Izuku and his friends more frequently, even joining their lunch table. Throughout the series, Izuku has had subtle parallels with Shoto's mother, Rei Todoroki. From giving Shoto eerily similar glances, Rei during her mental breakdown, and Izuku during his match with Shoto, to Shoto being openly vulnerable around both of them. Shoto has a deep love for his mother, and a deep friendship with Izuku as he was the one who inspired him to reach out to others.

Izuku is shown to worry if Shoto learns of his power, a good example was seen when Shoto asks him of his second Quirk when it awakes in his match but Izuku is able to cast it aside.

Shoto offers both Izuku and Katsuki a chance to intern with him and his father signifying the bond he's made with the two. During the Endeavor Internship arc, he invites the two over for dinner where they meet his family and learn more about the history of the Todoroki's. Tensions grow when Natsuo refuses to accept the normalcy of seeing his father take on an attentive role, believing he still hasn't taken accountability. Izuku intervenes to help Shoto explain his feelings. He claims that he believes that Shoto is preparing himself to forgive his father, and that he's a "caring person". It's heavily implied that he assesses this through his internalized feelings towards Katsuki and their rough past. Natsuo confirms Izuku's way of describing Shoto, explaining that he couldn't do the same because he's not as caring as Shoto. Just before that, Izuku called Shoto by his hero name, which also is his given name "Shoto". Upon departing their internship, Shoto's sister, Fuyumi, shares Izuku's hand and thanks him for being Shoto's friend.

During Shoto's fight with his older brother in the Paranormal Liberation War, despite having all of his limbs broken, Deku fires his Blackwhip from his mouth to assist Shoto. When Dabi tells Deku to stay out of the fight since it was none of his business, Deku replies that it was his business because he is Shoto's friend. Later on, Shoto would openly criticize Endeavor for letting Deku and All Might work alone, and during the battle between Class 1-A and Deku, tells Deku to let them share his burden of defeating All For One. He later joined the rest of the class in tracking him down to bring him back. He prevented his escape and told him to let the class join him in taking on his burden, knowing it was taking an emotional toll on him.

Tsuyu Asui
Tsuyu respects and admires Izuku for his heroic actions, as well as his victory against Katsuki. She becomes friendly with Izuku, requesting he call her by her first name, which is something he frequently forgets or is too shy and polite to do, so she corrects him. He sometimes remembers and forces himself to call her by her name to make her happy. She and Izuku are close friends. Tsuyu even notices the similarities between Izuku and All Might's powers, which worried him so he has to give her a vague answer.

During the U.S.J. Arc, she saves him from being attacked underwater and they work together well against their enemies. In turn, Izuku also tries to save her from being attacked by Tomura but fails, though they are both saved by Shota and All Might in the end.

In the Rescue Trial Arc, she is receptive of Izuku's plan to subdue the swimming villains, showing not only respect but also trust. After Shoto defeats Izuku in the Sports Festival, Tsuyu is one of the few students who go to Recovery Girl's office to see if he is okay, showing that she cares for him.

Tsuyu also implores Izuku not to join in Eijiro's plan to rescue Katsuki, since the recklessness could make them no different from villains. After the rescue succeeds, Tsuyu apologizes for harshly doubting their plan to save Katsuki, as they apologize for worrying her and they manage to mend their friendship.

During the battle between Class 1-A and Deku, Tsuyu would tell Deku that he matters to her as a friend and that it's okay to cry when you're scared. She says that if he wants to remain strong like a comic book superhero, she and the others won't let him go at it alone.

Fumikage Tokoyami
Their friendship is built on mutual respect towards each other. They team up along with Ochaco and Mei during the Cavalry Battle. Fumikage respects Izuku as a leader, as he leaves him with making the decisions of their team. Izuku himself respects Fumikage's strength and the power of his Quirk, acknowledging him as one of the strongest combatants in Class 1-A. They later sit beside each other to watch the Sports Festival. Izuku later cheers on Fumikage and Tsuyu during their exam when they are up against Ectoplasm.

During the training camp, Izuku along with Mezo resolve to save Fumikage from his rampaging Dark Shadow, a quest in which they eventually succeeded. After Fumikage is kidnapped by Mr. Compress, Izuku chases after the villain in order to save Fumikage as well as Katsuki. After Katsuki is captured, Fumikage tries to comfort Izuku.

Fumikage later joined the rest of the class in tracking him down to bring him back to U.A.. When trying to bind Izuku, he brought up how Izuku helped him with his Quirk. He was also shocked to see Izuku overcoming his power with his new strength.

Eijiro Kirishima
Izuku is on good terms with Eijiro, as in the U.S.J., when Izuku is wounded from trying to help All Might with Tomura, Eijiro tries to help him. Izuku is thankful though worried the latter will discover All Might's secret, but Cementoss intervened. Even early on in their first semester, Eijiro is sometimes shown to intervene when Katsuki starts antagonizing Izuku.

In U.A. Sports Festival Arc, when Shoto tells Izuku that he will defeat him, Eijiro tries to stop them from any further arguing, and after Izuku starts to talk negatively about himself, Eijiro tries to encourage him. Eijiro also tells Izuku that he is envious of his Quirk.

Eijiro seems to admire Izuku's growing confidence and seems to be impressed by his quick thinking and logical reasoning. He also seems capable of understanding Izuku's feelings to some extent, understanding how he feels when he is unable to rescue Katsuki. Eijiro also asks Izuku to help him in his plans to rescue Katsuki from the League of Villains. Izuku respects Eijiro by admiring his determination and he is aware of the bond Eijiro shares with Katsuki, which is what gives him the idea that Eijiro should be the one to retrieve him.

Days before the Shie Hassaikai Raid, Eijiro consoled Izuku after he told him, Ochaco, and Tsuyu what happened after meeting with Eri and Overhaul. In the Shie Hassaikai Arc, Eijiro and Izuku are shown to be on even better terms than previously, often interacting in friendly ways. They also take part in the Shie Hassaikai Raid and defeating several villains. Overall, the two are good friends.

Eijiro also participated in attempting to bring Izuku back to U.A. because of All For One hunting him. It is revealed that Eijiro is well aware that Izuku once tried to save Katsuki from the Sludge Villain. He compared what the class was doing was similar to how he took action. This showed that he respected his fellow classmate for his bravery.

Yuga Aoyama
The two first met at the entrance exams where Yuga saves Izuku from being attacked by a robot, though he does say he only did this for points, as he remarks that the latter makes good bait and that he would most likely not see him again as he doesn't think he'll be accepted into U.A.. Izuku later excels in the exams and therefore becomes classmates with Yuga. It has been shown his opinion has not changed, as he again remarks on Izuku's lack of skill to Ochaco. However, Izuku surprises him with his powerful Quirk which allows him to remain in the school.

After this, the two have no further interaction that was notable until the Remedial Course Arc. Yuga acts strangely around Izuku, who would note that he can never get a good read off the latter. Izuku is later scared when Yuga spies on him as he sleeps and leaves a message (in cheese) to say he knows Izuku's secret, which left Izuku wondering if Yuga is aware of the truth about his Quirk. In training, Izuku is called out to by Yuga and is shown one of his new moves, though it causes Yuga severe stomach problems to use. Seeing him in this state, Izuku takes Yuga away to recuperate before he asks him what he meant in his message.

Yuga explains that he is aware of Izuku not being accustomed to his Quirk and reveals that he has gone through a similar experience and compares his powers leaking out in his childhood out to Izuku's initial lack of control of his own Quirk. He then tells Izuku that he is not alone in hardships, as it is better to face them together or they won't excel. His words relieve and cause Izuku to smile and thank him for his support. After a few days, Izuku and Yuga become good friends, with some of the class noting on their more frequent interactions.

During the U.A. School Festival, Izuku and Yuga make a frayed rope, with the latter claiming it as a symbol of their friendship. He is tasked with securing Yuga as the disco ball since the class knew of their bond.

After the war, he was stunned to discover from Toru that Yuga was the traitor who had been aiding All For One. When confronting him, Izuku revealed that he noticed Yuga was not being his usual self while Yuga admitted with great remorse that this was all true. Yuga also noted how he fell into despair upon learning of their similar stories on being Quirkless, before he reluctantly tried to attack only for Toru to intervene. Izuku managed to stop him and his parents from fleeing and brings them back to the school grounds for interrogation. During so, Izuku tells Yuga that despite learning that he was the traitor, he doesn't bear any ill will to him, comparing him to Lady Nagant; a person who's spirit was crushed, but not their soul, and citing all the other good things he has done over the school year. He reaches his hand out to him and tells him that he still believes he can be a hero, and that no one should be labeled a villain for the rest of their lives for committing a single crime.

Minoru Mineta
Izuku gets along very well with Minoru, though like most of his classmates, he is put off and disgusted by Minoru's perversions, although he still admires his heroism and quick thinking in difficult times. In turn, Minoru has come to admire Izuku for his acts of heroism and for believing in his abilities as a hero, though he is somewhat skeptical at first of Izuku's determination. The two have become friends, particularly following their battle together against the League of Villains. They have also been seen talking to each other and hanging out in-between classes on occasion. During the obstacle course, Izuku was the only one who was concerned for Minoru when he was hit by a villain bot and shouted if he was okay, and in the Beast's Forest, Izuku rushes in to save Minoru from one of the Earth Beasts. It has been hinted throughout the series that Minoru is jealous of how Izuku gains attention and affection from other females (Ochaco, "Camie", Mina, etc).

It appears he has picked up some of Izuku's habits, as he uses his own knowledge of heroes' Quirks to defeat Midnight. Witnessing this, Izuku is impressed by Minoru's ingenuity and praises him for it. During the battle between Class 1-A and Deku, Minoru says that he never thought the power of One For All was amazing, but what made Minoru admire Izuku was how he leads everyone to victory despite being scared himself.

Once Izuku broke down into tears, Minoru attempted to rush to comfort him but was held back by Tenya. After the civilians accepted Izuku back into the high school, Minoru ran to comfort him alongside Kota. He later helped bathe Izuku and agreed with them they forgive Yuga despite him being a unwitting traitor for All For One.

Mashirao Ojiro
They get along well, though Mashirao didn't team up with him since Izuku was a target in U.A. Sports Festival Arc. Despite this, Mashirao still tries to warn him about Hitoshi's Quirk, Izuku also standing up for him after Hitoshi insults him. Mashirao worries for him but is relieved when he emerges from the fight victorious.

During the Vs. Hero Killer Arc, he is very amazed that Izuku improves his Quirk and overcomes his drawbacks.

He also tries to comfort Izuku at the training camp after he was the only one left without a partner.

During the battle between Class 1-A and Deku, Mashirao grabs ahold of Deku with his Tornado Tail Dance, telling him that he'll never forget how frustrated he got for him during his fight against Hitoshi at the Sports Festival, and they all can't overlook how ragged he's become fighting alone.

Mezo Shoji
The two have had little interaction, but are on good terms and have respect for each other. Shoji saves Izuku twice during the school trip, first from a rampaging Dark Shadow and second from Himiko. Mezo trusts Izuku, as he is willing to lead the out of control Dark Shadow towards where Shoto and Katsuki were despite the danger it placed him in, as that was Izuku's plan. Mezo also carries an injured Izuku on his back throughout the attack during the training camp.

Despite their efforts they fail to save Katsuki, resulting in Izuku breaking down. Along with Fumikage and the others, Mezo tries to comfort Izuku on their loss. Later he visits Izuku in the hospital with the rest of the class.

During the battle with Deku and Class 1-A, Mezo aided Fumikage and Momo Yaoyorozu in binding Izuku. He brought up what Izuku said about getting strong to even scare All Might and asking if the class really looked helpless.

Denki Kaminari
Izuku and Denki are on good terms and they're sometimes seen talking together. Denki also considers Izuku as "very diligent". He is also seen to praise Izuku when the latter saves All Might by using for the first time, his shoot style during training to create ultimate moves. Like Minoru, Denki has been shown to have been slightly jealous of Izuku gaining affections of females like Himiko and Ochaco, however he still views him as a good friend.

During the battle between Class 1-A and Deku, Kaminari grabs onto Izuku telling him that even though One For All is important, and they may not have any hobbies in common, he's still someone he considers a friend.

Hanta Sero
Izuku and Hanta are shown to be on good terms with each other, and are friends. Like most of his classmates, Hanta visited Izuku while he was recovering from his injuries, and tried to comfort him over the loss of Katsuki. In the Provisional Hero License Exam, Izuku and Ochaco grouped up with Hanta, and displayed great teamwork in eliminating some of the opposing teams. Hanta would also comment on how Izuku's Blackwhip is similar to his Tape quirk, and trained with Izuku alongside Ochaco, Tsuyu and Katsuki. During the battle between Class 1-A and Deku, Hanta reminds Izuku on how scary-looking Blackwhip is, while Deku remembers him teaching him how to control its shape.

Kyoka Jiro
Though they rarely interacted initially, they mutually respect each other and have formed the beginnings of a friendship. In the recent chapters, they have both had more frequent interactions and are on good terms with each other. Kyoka is amazed by Izuku overcoming the drawbacks of his Quirk.

The days before the School Festival, the two interact more frequently. Kyoka finds Izuku's notebooks where Izuku notes heroes and his classmates' abilities very interesting and impressive, and asks him for pointers to help advise the band. He is happy to share a habit with someone else, even if Kyoka only wrote about music he is very impressed and he happily agrees to help her with her notes leading up to the School Festival. During final preparations for the festival he comments on how Kyoka 'knows her stuff.' when it comes to music. Later during his fight with Gentle Criminal he recalls his time preparing for the Festival with Kyoka and the others and this helps give him the strength to fight harder to prevent him from getting the festival canceled and to make it back in time to help in the performance.

During the Joint Training Battle against Class 1-B, she is shown to be visibly and vocally worried when Izuku's Blackwhip emerges and goes out of control.

After the resulting battle with Tomura Shigaraki, Kyoka shows up outside of his hospital room asking Ochaco if he's woken up yet.

During the battle between Class 1-A and Izuku, Kyoka tells Izuku she is very happy that he not only helped her with how to organize notes during the Culture Festival, but also sharing a hobby of note-taking. She also comments how Izuku got stronger.

Kyoka was also willing to support Izuku, and cares for him enough that when thinking of All For One making Izuku suffer because he has One For All makes her angry, and would dare to attack anyone who would harm her friends.

Mina Ashido
Mina and Izuku have mutual respect for each other, though they have rarely interacted. Mina has a playful bounce off of Izuku's muttering, though she doesn't seem to mind it, unlike most characters. Their relationship improves during the weeks leading up to the School Festival, when, interested in Mina's dance skills, Izuku asks her to teach him some dance movements, a job that Mina happily accepts. She and Izuku are shown to have a great time despite the latter's bad dancing.

During his fight with Gentle Criminal, he uses Mina's dancing moves to out-maneuver him. He also mentally thanks her for his victory.

Mina has been shown to care about him, as she visited him in the hospital when he was injured. She also asked Izuku about his Quirk acting strange. Both of them helped each other in defeating Class 1-B, showing that they work well together. After their team wins the fifth round in the Joint Training Battle, Mina teases both him and Ochaco for the latter grabbing onto Izuku so hard in her attempt to save him, which causes both Ochaco and Izuku to turn bright red in embarrassment. Although he is unaware, Mina supports him and Ochaco and hopes for them to be together. Despite this, they seem to be on friendly terms.

After battle between Izuku and Class A, Mina pleaded Izuku to come back with them because she didn't want to lose anyone anymore, showing that she cares for him.

Momo Yaoyorozu
They are classmates of Class 1-A and are both voted as the Class reps, however their partnership does not last long due to Izuku stepping down for Tenya to replace him.

There is not much interaction between the two after, though Izuku, along with Tenya and Momo, would later join Eijiro and Shoto to rescue Katsuki. Due to the group's teamwork, they are successful.

Both are also friends of Shoto and were seen showing concern for him after he failed the Provisional Hero License Exam. Despite her being the smartest person in Class 1-A, she has been shown to look up to Izuku for his leadership, showing a good level of respect and confidence in him. She also joined the rest of the class in trying to get him to return. Momo tried to trap Izuku with one of her creations, as he was amazed by her ingenuity. She implored him to come back to U.A., stating she and the others were prepared to fight side by side with him while prioritizing his safety. This shows she sees him as a friend.

Toru Hagakure
The two have not interacted much, though Izuku and Toru are on good terms, if not friends. Toru does not seem to mind when Izuku is muttering to himself. One week before the First Term Final Exam. She was sat with him, Tenya, Ochaco, Tsuyu, and Shoto at the Lunch Rush Cafeteria discussing how they were going to pass the practical exam. Toru also joined the rest of her class in trying to get him to return to U.A. after he left to protect them.

Like the rest of her class, she puts great trust in him. This was the best seen when she discovered that Yuga Aoyama was the U.A. traitor and immediately rushed to tell Izuku this news.

Toru had defended Izuku from Aoyama's Navel Laser and was present when apprehending him and his parents.

Class 1-B
He is on good terms with most of Class 1-B, except Neito Monoma, who resents the class.

Neito Monoma
Due to his resentment and envy towards Class 1-A, Izuku is a target of Neito's taunts and mockery.

During lunchtime, he intentionally bumped into a rambling Izuku's head and sarcastically apologizes to him, commenting that his head was so big that he just couldn't help but to bump into it. Izuku was silent as Neito insults him and the rest of Class 1-A, saying that they only want to gain even more attention just like they did in Sports Festival and when Izuku, Shoto, and Tenya encountered Stain, before being knocked out by Itsuka Kendo twice. Izuku only commented on Neito's behavior being strange.

They clash during the fifth round of the Joint Training Battle, Neito regards himself as a "side character" and Izuku as a "main character". Neito manages to use Full Cowl after touching Izuku, but is pinned down by Ochaco before even getting the chance to attack him. Izuku was even worried at what might happen if his Quirk was copied.

Even though Class 1-B loses the match, Neito still retains his old demeanor. Neito begins to rant about how his team didn't lose in terms of substance and reveals his newfound knowledge relating to Izuku's Quirk. He implies that he could easily beat Izuku if they were to have a rematch. Despite his disrespectful and harsh attitude during the battle, Izuku does not seem to hold any grudge against Neito, in fact he was worried about him when he tried to use One For All, fearing for his physical integrity.

The next day, while trying to find more out about Eri's Rewind to help Shota, Neito reveals aspects of One For All that Izuku himself doesn't know. Neito says that he couldn't use Izuku's Quirk properly because, just like Eri's, it requires stored-up energy to work, and as Copy can't take that it isn't possible for him to use it. Izuku was relieved to hear this failed, due to the repercussions of an unprepared vessel using One For All.

Mei Hatsume
Mei and Izuku first meet during the Sports Festival. Mei takes an immediate interest in Izuku when he gets first place in the Obstacle Race and as a result, got the ten million point headband for the Cavalry Battle. She sees this as an opportunity to bring attention to her inventions by using Izuku and approaches him before the battle, asking to join his team. In return for her joining, she offers him and his other teammates support equipment to aid for their battle. Her tendency to get in his personal space creeps Izuku out, though they still get along well because of their shared admiration for heroes. Currently, they seem to be on close terms with each other.

After the U.A. Tournament, the two do not meet again for a while, until Izuku wants Power Loader's help in improving and redesigning his costume. Mei recognizes him during their second encounter, but doesn't appear to remember his name, and dismisses it in order to go back to her inventions, only to return her attention back to him when he brought up his purpose for entering the workshop. She provides Izuku some options for improvements on his costume and soon creates Izuku's Costume Gamma.

Overall, the two generally get along well as Izuku has no problem talking with Mei during their first encounter. They became acquainted over a jetpack Mei creates that is similar to a hero Izuku is familiar with, Airjet. Izuku appears to tolerate Mei better than some of his classmates, like Tenya and Ochaco, since he shares some similarities to her as he creates ways to counter the Quirks of others and rambles, and she does the same about gadgets.

It is shown that while still having trouble training, he goes to see her for a new gadget that might help him progress with his powers. She has gotten used to him, as she now remembers his last name, in contrast to her old mistake. Izuku is still friendly to her though he is put off by her habit of getting in his personal space.

Mei later gives Izuku the new mechanical gloves that he asked for. She hands him the instruction manual for them before running off after he thanks her.

Mei's invention comes in handy as Izuku uses the gloves to defeat the villain Gentle Criminal.

Hitoshi Shinso
They first meet in the fighting tournament of the Sports Festival. Izuku learns much about Hitoshi's Quirk from Mashirao, but accidentally plays into Hitoshi's hands, though the powers of those who previously wielded One For All free him from Hitoshi's control. Hitoshi is shocked by this and tries to control Izuku again by claiming to be jealous of Izuku's Quirk because of its combat efficiency.

Izuku ignores him, though internally understands Hitoshi's situation as he himself was considered unfavorable due to having no Quirk before One For All. Before their battle in the Sports Festival, Hitoshi and Izuku are hostile to each other, but after their battle, Hitoshi seems to have gained respect for Izuku, telling him not to lose too pitifully while Izuku respects Hitoshi's goal to enter the Department of Heroics.

Afterwards, they meet again, and while Izuku is friendly to him, Hitoshi ignores his greeting. Izuku is later shocked that Hitoshi would play a role in a training exercise in the Department of Heroics. Izuku looks forward to a rematch between them and remarked to himself how fitting it was since he had visions of his Quirk both in their last fight and future fight.

When Izuku's Quirk goes out of control during their clash in the fifth round, Hitoshi, with Ochaco's help, manages to stop Izuku's rampage. Thanks to that, Izuku returns to normal and the round continues. He ends up beating Hitoshi in their rematch, but is still surprised and impressed at his vast improvement. Later, Izuku thanks him and Ochaco for saving him, something Hitoshi took in stride. Izuku was also amazed that Hitoshi will be in the Hero Course for the second year.

Mirio Togata
At first, Izuku is largely put off by Mirio due to the unusual nature of their first encounter. Izuku looked very freaked out. Furthermore, Izuku is skeptical of Mirio's status as one of "The Big 3" at U.A. due to Mirio's subpar performance in the Sports Festival the previous year. This changes after Mirio gives an excellent demonstration and explanation of his Quirk and fighting technique, after which Izuku grows to have a great amount of admiration for him, even commenting that Mirio talks just like a Pro Hero already. Mirio also respects Izuku for his quick thinking in their exercise.

Izuku's respect grows upon learning that Mirio was one of the originally proposed candidates for inheriting One For All. Though sometimes he is still a bit put off by Mirio's intense amiability and enthusiasm, Izuku and Mirio get along very well and are very similar in terms of heroic ideals. Mirio puts in a good word about Izuku with Sir Nighteye, and the two work together in an internship there for a while.

He was visibly disturbed when he learned that Mirio's Quirk was taken by Overhaul, and expressed anger towards the villain for that.

After Nighteye's death, when Izuku sees how optimistic Mirio is, Izuku goes as far as to propose that Mirio could take Izuku's Quirk, indicating how Izuku believes that Mirio is truly the worthier candidate for One for All, like Nighteye had said. However, Mirio turns it down as he has faith that Eri might master her Quirk to restore his and believes in the words of Nighteye about being a hero.

Izuku is impressed by this and accepts Mirio's determination, and it seems they become closer friends afterwards. The two get along and Izuku still looks up to Mirio for maintaining a smile in spite of his situation, which is something All Might also did in the face of adversity.

During the Paranormal Liberation War, Izuku is very happy to see that Mirio has regained his Quirk, thanks to Eri.

When Izuku finally arrives for his confrontation with Tomura in the Second War, he is horrified to see the Heroes' injuries, Izuku begins to lose his head and rage as "Tomura" proceeds to taunt him. However Mirio calms him down saying that they haven't lost anybody yet, so they need to keep fighting. "Tomura" claims it's all merely "empty talk" to avoid facing facts and reality, but Mirio continues that as Heroes, they have to talk the talk in order to turn their ideals into reality. This helps him calm down, apologizing to Mirio. When Izuku then asks if the real Tomura is still there, Mirio rebuts "All For One's" lies,  by telling Izuku about the previous incident when he spoke harshly to him, causing him to throw a fit as if he were a child, knowing he isn't "fully merged"; the more he was provoked, the more unstable he became.

Tamaki Amajiki
Izuku hasn't interacted with Tamaki as much as with Mirio, but they seem to be on good terms. When Mirio challenges Class 1-A students to a fight, Tamaki was on the wall watching the fight and listening intently to Izuku gathering some of his classmates together to come up with a strategy against Mirio and when Izuku learned that Tamaki was shot by a Quirk-Destroying Drug, he and Mirio showed concern for him. In the operation against the Shie Hassaikai, Izuku was shocked and scared when Tamaki wanted to stay behind to fight three of The Eight Bullets and Tamaki asked Izuku to take care of Mirio because he can act recklessly. During the preparations for the U.A. School Festival, Izuku hears Tamaki speak and is surprised when he suddenly paralyzes.

During a training exercise in which Tamaki acted as villain against Class 1-A, Izuku was very surprised when Tamaki wanted to leave the exercise and despite having the opportunity to hit Tamaki and knowing that he was only acting like a villain, refused to hit him and restrained him instead, asking him to surrender. When Tamaki asked Izuku why he didn't hit him, Izuku replies that he didn't want to hurt him.

Kota Izumi
At first, Kota despises Izuku and Class 1-A for always working so hard to better themselves against fighting villains. He even goes as far as to hit Izuku in the crotch for trying to be friendly towards him, as he voices his dislike of heroes. In spite of this, Izuku holds no grudge and tries to get along with Kota due to their similar circumstances of both being "Quirkless" (Izuku not originally being born with a Quirk and Kota refusing to use his Quirk), though he has no luck due to a disagreement in their ideals. Because of his past, Kota ignores anything that dealt with heroes and villains, and even Quirks altogether. After finding his secret hideout, Izuku tries talking to Kota, only for him to snap at Izuku because he's never gone through what Kota has.

However, Izuku saves Kota from Muscular (who is also the same villain who killed Kota's parents) after realizing he is in danger. When Kota asks why Izuku took it upon himself to save him, especially by how he treated him, Izuku states he had seen the latter was in danger and he had to save him. Izuku shields Kota from the Muscle Augmentation villain at all costs, even going past his limitations just to keep Kota safe.

During the battle, Kota uses his Quirk out of desperation in an attempt to help Izuku. From this, it is shown Kota has gained respect for Izuku and Kota would watch Izuku overpower and defeat Muscular. After the battle, he tells Kota that his parents died to protect him and says he risked his life for him because he wants his acknowledgment as a hero. Izuku then tells Kota to help save others just as he helped save him.

At the hospital, Izuku soon gets a letter from Kota, who apologizes for his previous treatment towards him and thanks him for saving his life. He is extremely happy to have impacted on someone, especially someone who had originally hated heroes. Izuku later uses the letter to show All Might and his mother that he is well on his way of being a hero after having an effect on someone.

They met again when the Wild, Wild Pussycats visited U.A., and Izuku is happy to see him and thanks him for the letter. Shino soon points Izuku out to the new shoes Kota has, which look exactly like Izuku's shoes. Kota becomes very embarrassed after Mandalay points out that they match Izuku's. Kota admires Izuku as a hero for saving his life, going as far as to come running toward him when he breaks down crying after listening to Ochaco's speech.

Eri
Izuku and Eri never fully interact, but the short time they have with one another built a powerful bond between the two. When Izuku first encounters Eri, seeing the bandages she had as well as how fearful she was towards Overhaul, Izuku tries to protect her from him until he is forced to let her go back. After learning how Eri is being experimented on by having Quirk-erasing bullets manufactured from her body, Izuku is horrified by the act and angered at himself for letting her go back to that. Shota even deduced that Izuku is going to act recklessly to try and save her even if he tried to stop him, which Izuku didn't deny.

When they finally reunite in the battle against Overhaul, Izuku immediately follows orders to try and rescue Eri, and even pushes himself to use One for All 20% to protect Eri and defeat Overhaul. Even though he is beaten down by the villain afterwards, and Eri comes back to Overhaul declaring that Izuku cannot save her, and this is not his business, Izuku declares that because Eri was crying, he would save her no matter what.

After taking Eri from Overhaul, Izuku tells her that he will not let go of her again. When he experiences her Quirk being used, and being told how dangerous it is to be with Eri, Izuku still refuses to let Eri go, explaining that because of how her Quirk has reverted the damage he has done to himself using 100% before he could even feel pain, he states that Eri possesses a "kind, gentle Quirk", something that drives Eri to tears because she is always told that her Quirk is destructive and dangerous. This also makes Izuku go as far to use Full Cowl - 100%, something that would destroy his entire body at blinding speed, to make use of Eri's Quirk, and asks her to lend him her strength.

After the battle is over and they are in the hospital, despite Izuku being discharged, he wants to stay by Eri's side until she wakes up, but is eventually convinced by Shota to go back.

Izuku later meets her again and is able to properly introduce himself to her. He and Mirio invite her to the School Festival to have fun after noticing she is still haunted by Overhaul's influence.

When she arrives at U.A., he is excited to see her and promises to perform for her on stage.

Izuku is intent on fulfilling his promise as he prevents Gentle Criminal from attacking the school and fights the villain by himself. Izuku later performs on stage and catches a glimpse of Eri smiling, pleased at his success. Eri seems to even consider Izuku as her older brother, due to their close bond.

Melissa Shield
Despite the short time they've known each other, Izuku and Melissa have become well-acquainted with each other. During their initial meeting, Izuku was flustered by Melissa by how close she was to his body when examining his scars and hero costume. Once Melissa started touring him around I-Expo, Izuku quickly bonded with her over their similar interests in heroes and support tech. Izuku even preferred Melissa to call him by his hero name instead of his first or last name. The two also share a goal in wanting to save people. Melissa also shared her past of being Quirkless, as Izuku related to her since they both overcame it in their own way.

During the events of the I-Island Incident, Izuku and Melissa showed great teamwork and cooperation in stopping Wolfram and regaining control of I-Island's central tower, in a way that mirrors how All Might and David Shield used to work in their earlier years. Izuku comes to see her as a good friend and develops a protective side to her as he defends her from any attacks made by Wolfram or his henchmen.

Katsuma Shimano
Deku met Katsuma during the Hero Work Recommendation Project, when his sister Mahoro organized various mischiefs to try to show him that heroes were not a big deal. All in all, Katsuma apologized to Deku for his sister's antics, starting a better relationship when they discover that the two share a similar admiration for heroes. Izuku realizes that Katsuma wants to be a hero, although Katsuma didn't considers his Quirk good for that. However Izuku assures him that anyone can be a hero as long as they focus on putting their effort, which makes Katsuma very happy.

During Nine's attack on Nabu Island, the relationship between the two gets closer, with Izuku protecting Katsuma from the villains and praising the boy's bravery on numerous occasions, as well as thanking him for using his Quirk to heal him. When he prepares to leave the island, Izuku says goodbye to Katsuma, saying that he will be waiting for him at U.A. High.

Mahoro Shimano
At first, the relationship with Katsuma's older sister wasn't a good one, as Mahoro tried to show her brother that heroes are useless, so he was the victim of several of her pranks. However, Izuku held no grudge about it, and after his conversation with Katsuma, he knew that Mahoro's behavior is because she wants to prevent Katsuma from becoming a Hero because it's dangerous, which reminded him of his mother's concern about him.

Everything changed during the attack on Nabu Island, where Izuku fought with all his might to protect her and Katsuma. After defeating the villains, their relationship improved greatly, and since then Mahoro respects Izuku.

Rody Soul
Izuku's relationship with Rody did not start out well, as the U.A. student pursued the street rat when he had ran off with a case of stolen jewelry following a robbery involving two villains. Izuku eventually caught up to Rody, though the latter managed to make Izuku back down by saying that he was a businessman while also bringing up that Izuku was doing hero work in Otheon without proper jurisdiction. After a short scuffle over the case, Izuku was shocked to find out that Rody's briefcase contained a number of books, notes and documents, with no stolen jewelry to be found. After this, Izuku profusely apologized to Rody for suspecting him, leaving Rody to anxiously walk away to try and recover the stolen goods, although Izuku notices his nervousness and follows him to inquire if he's okay. Once the Otheon Police arrive and corner Rody, Izuku tries to defend him only to save the young man when the police open fire on him. Later on, after escaping the police and a villain pursuing them, Izuku resolves that they find out the secret of the case. When Rody says that he doesn't want to be involved, Izuku promises to protect him should trouble arrive. Regardless, the two are given no choice but to team up when Izuku is framed for mass murder and Rody is placed as his accomplice.

Even after Rody tried to abandon Deku and turn the briefcase over to Humarise (Izuku was woken up by Pino, representing Rody's reluctance to leave him behind), Izuku still saved him from Rogone and took an arrow to the chest protecting Rody. After escaping the villains, Rody expresses his surprise over how Izuku ran to protect him, despite being betrayed by him. Izuku responds by telling Rody that he can't help but save someone in trouble, regardless of who they are. Over time, Izuku and Rody bond closer as they travel to Otheon's neighboring country Klayd, with Rody even telling Izuku about his dream to be a pilot, his past and his little siblings, Roro and Lala. Likewise, Izuku tells Rody about how he struggled with his Quirk and how he's grown during his journey to become a hero. Their relationship ultimately grows from unlikely partners of circumstance to trusted allies.

At one point, Izuku asks about Rody's Quirk, and Rody tells him after Izuku promises not to laugh. Rody confesses that Pino is his Quirk and that she reflects his inner feelings, making it impossible for him to lie. Despite Rody's embarrassment, Izuku tells him that he sees his Quirk and being unable to lie as a great power.

After the two solve the briefcase's secret, alongside Katsuki and Shoto, Izuku resolves to stop the Trigger Bombs using the deactivation key Rody's father sacrificed his life to build. Izuku was shocked and devastated to see Rody apparently betray him again by giving the key to Flect Turn, but then saw Pino confirm that his actions were a lie to get Flect to drop his guard. Together, Izuku and Rody managed to deactivate the Trigger Bombs and save the world. As they part ways, Rody tells Izuku that he's glad to be rid of him and not to come back to Otheon as he only causes trouble, but Izuku sees Pino crying over his departure confirming those words to be a lie, and the two embrace as they bid each other farewell.

Gran Torino
Gran Torino requested Izuku to be his sidekick in an internship so that he can properly teach Izuku about the One for All Quirk. Izuku first learns of him from All Might and wonders what type of mentor he is after All Might becomes scared.

Gran Torino and Izuku were off to a bad start when they first met, with Gran Torino putting up a façade of being senile and Izuku being disappointed with having to train with someone who was no longer functional. However, when Izuku moved to leave Gran Torino promptly dropped his façade and showed Izuku what he was really capable of as Izuku was amazed by his true nature. He saw the similarities between All Might and Gran Torino's personality shifts which helped him better understand their connection and accepted the offer to train. He started to gain respect for Gran Torino, politely calling the elderly hero "Mr. Torino". They bonded to an extent and Torino's teaching helped Izuku gain better control of his Quirk without hurting himself. Torino also protected Izuku from a Nomu while Izuku was worried for him.

Gran Torino has shown to be impressed with Izuku, stating that All Might chose a fine successor, due to Izuku's quick thinking and potential even stating that Izuku has the potential to become a "monster" due to these traits. As they parted ways, Gran Torino asked him what his name was and Izuku replied it was Deku, with Gran Torino becoming the second person to make Izuku proud of his nickname.

It also shows how strong their connection was when Tomura punches Gran Torino in the chest, Deku screams in pain. In previous situations, after Izuku is put in a situation that negatively effects his emotions, his power tends to increase and when he saw Gran Torino on the floor, he was able to control Blackwhip for a longer amount of time than usual.

Sir Nighteye
Izuku was very surprised to hear that All Might had a sidekick from Gran Torino. In their first meeting, he was intimidated by Sir Nighteye. The two were mostly at odds due to Sir's cold nature and skepticism of Izuku being the next Symbol of Peace. However, they both realized they were huge fans of All Might, with both having extensive knowledge of him as well as extensive collections of merchandise. Sir hired Izuku as an intern, and Izuku has been working since then to prove his worth to him.

After learning more about All Might's relationship with Nighteye, Izuku wanted to make the two meet so they can reconcile. Though Izuku wasn't able to find the time to bring it up due to the rescue mission for Eri, he got to tell him after the rescue was complete and Nighteye was taken to the hospital.

Izuku was horrified when he learned that Nighteye was going to die, and pleaded to him to keep hanging on, and cried for him as he died but not before Nighteye gave Izuku his blessing as All Might's successor.

Despite how Nighteye praised Izuku for being able to change the future, giving him hope for once, Izuku ultimately believed that Nighteye was right about Mirio being the worthier heir for One for All and even tried to pass it onto Mirio, but was rejected. Izuku also decided to live to Nighteye's expectations as a way to honor his memory.

Endeavor
They first meet during the Sports Festival, where the Pro Hero tells Izuku to not hold back against Shoto. After having heard about Endeavor's conflict with All Might, and knowing about Shoto's past, being disgusted to hear him view his son as a tool, Izuku annoys Endeavor with his declaration of not being All Might, and that Shoto isn't Endeavor.

They meet again when Shoto tells him and Katsuki to intern under his father. While Endeavor is uninterested in training the others besides his son, he still remembers Izuku's words to him earlier, commenting to him about them. After finally committing to training them, Endeavor is surprisingly able to understand Izuku's mumbling about the nature of his Quirk and how he wants to control it, providing him with useful advice. He develops a newfound sense of empathy and understanding towards Izuku, recognizing his power as not only similar to All Might's, but also likening the danger the raw power has to his body to his families' Quirks, saying he's "just like us", though Izuku is unsure of what he means. His teachings and training are what eventually allow Izuku to have full control over Blackwhip.

During the Paranormal Liberation War, he demonstrates worry for Deku when he realizes that he is Tomura's target, and then a sense of trust when them, Katsuki, and other Pro Heroes work together to take down Tomura. During Shoto's fight with Dabi after it is revealed he is his older brother Toya, Deku ended up standing up for Endeavor, telling Dabi that while his past actions were awful, he is trying to change, and he wants to watch him do so. His words ended up snapping Endeavor back to his senses allowing him to get one final blow on Gigantomachia.

Endeavor is now currently working with Izuku, alongside Hawks, Best Jeanist, and the Lurkers in the pursuit of All For One and the League.

Hawks
Izuku first met the pro hero after he assisted with Starservant's minions. He was very amazed to met him, as Hawks just became the second best hero in Japan while the latter was impressed that he and classmates were helping Endeavor.

In the time after Liberation War, Hawks is now currently working with Izuku, alongside Endeavor, Best Jeanist, and the Lurkers in the pursuit of All For One and the League.

Naomasa Tsukauchi
Izuku met Naomasa after the events of the U.S.J. Incident, Naomasa came to Recovery Girl's Health Office to question All Might on the villains who attacked the U.S.J, Izuku was surprise to see that it was ok for Naomasa to see All Might in his skinny form, All Might introduced Izuku to Naomasa.

After the incident with Tomura unintentionally meeting Izuku at the Kiyashi Ward Shopping Mall. Izuku was brought to the Police Station to report everything that happened during that Incident. As Izuku wished that he could have done more to detent Tomura, Naomasa consoled Izuku that he did a great job keeping his cool in that situation as most people would have lost their cool. Naomasa also called All Might to the police station and told Izuku not to worry as All Might never failed to save someone. Naomasa also call Inko to the police station informing her of the Incident. Naomasa also told Sansa Tamakawa to give them a ride home.

Kenji Tsuragamae
After Izuku, Tenya, and Shoto defeated the Hero Killer: Stain at the Hosu Hospital he told the three about Stains's injuries and that it was against the law for unlicensed heroes to bring any injuries to any villains and that how the early heroes applied to the rules. He told the three that they would have to face the consequences of breaking the law, while also telling them that their supervisors would receive punishment as well.

However, since Kenji did not want to ruin any of the young heroes futures, he told them that Endeavor would be given the credit on taking down the Hero Killer, meaning that they would not receive any repercussions for their actions, nor would they receive any praise for defeating Stain. As they agreed for Endeavor to receive the credit, Kenji also bows to them and thanks them for keeping the peace.

Tomura Shigaraki
Tomura is Izuku's adversary. Due to them being groomed to be the successors of their respective mentors, Izuku and Tomura mutually despise each other; Tomura despises Izuku for his admiration of All Might (someone he hates) while Izuku is disgusted with Tomura's villainous actions. During the U.S.J. Arc, Izuku saved All Might, which caused Tomura to take an interest in Izuku, as shown when he watched Izuku's match during U.A.'s Sports Festival.

Later in Kiyashi Ward Shopping Mall, they unintentionally met each other again, so Tomura decided to talk with Izuku about the difference between him and Stain. After hearing Izuku's thoughts on the matter and before leaving the shopping mall, Tomura declared that the next time they meet, he would show Izuku no mercy.

Later on, during the Paranormal Liberation War, Deku goes into battle with Tomura when he learns that he intends to come after his Quirk. While originally attempting to avoid him, he engages him along with Katsuki and the other heroes in an attempt to protect Eraser Head. As the fight goes on, Deku's hatred for Tomura continues to grow, and it only worsens when he sees the villain impale Gran Torino in the chest. After seeing this, Deku screams and grabs Tomura, declaring that he will never forgive the villain, bearing the same amount of hatred for Tomura as the latter would never forgive anyone like him because he is a hero.

However, after Tomura's attempt to steal One For All, Izuku witnesses him being usurped by and trying to fight back control against All For One, who eventually succeeds in taking command of his main body. Despite all the terrible, unforgivable things he's done, Izuku still thinks back to Tomura's troubled face and recognizes him as someone who needed saving.

When conversing with the One For All vestiges, they all understand Izuku's hesitation, having sensed his emotions when he first noticed Tomura suffering. Regardless, Nana states that Tomura is likely beyond saving and urges him to find the resolve to kill him if necessary. In response, Izuku reflects on how he felt Tomura's emotions while inside the mental world, and he was able to see a little boy crying inside. Izuku notes that while Tomura did kill many people and hurt many friends, One For All was meant to save people, and ultimately, while he does consider the possibility that he will have to kill Tomura, Izuku still voices his desire to try and save Tomura first.

Once Izuku defeats All For One's vestige within Tomura's body, it allowed him to emerge once again. While his central aspect as "Tenko" was still crying out to Izuku to save him, it could only manifest itself through continued spite in his present self as "Tomura", pushing Izuku away by declaring he was "[his] villain." After fully regaining control of his body Tomura declares his one and only hope : The destruction of everything relating to the house he grew up in. He then tells Izuku that's the only thing that will save him, as he is tackled out of U.A. Izuku tells Tomura he won't allow him to do that, but also states he won't pretend that he didn't see Tomura's tears, as the two adversaries charge at each other.

Tomura is considered a dark reflection of Izuku. While Izuku is working to become the greatest hero, Tomura is working to become the greatest villain.

Dabi
Izuku briefly meets Dabi when the Vanguard Action Squad attacks Classes 1-A and 1-B's field training. He dodged Dabi's fire attack and witnessed him abduct Katsuki.

He meets Dabi again during the Paranormal Liberation War in Jaku City after he arrives on the back of Gigantomachia, where he is stunned to learn that Dabi is actually Shoto's eldest brother and Endeavor's first son, Toya Todoroki, whom he had learned about from Shoto when he invited him and Katsuki to his house for dinner. He listens to Dabi claim that he plans on killing Endeavor and tries to stop him before Best Jeanist arrives. When Shoto starts fighting Dabi and starts getting overwhelmed, Deku uses Blackwhip to help him, causing Dabi to retort for him to stay out of family business. Deku replies saying that Shoto is his friend and Endeavor is his mentor, and while he knows Endeavor's actions were awful, he is watching in earnest how he is trying to change. He yells to Dabi that he isn't Endeavor, which has no effect on Dabi but wills Endeavor to finally take action again.

Himiko Toga
Himiko first encounters Izuku when the Vanguard Action Squad attacks Classes 1-A and 1-B's field training. Himiko jumps him and briefly introduces herself before she is pushed away by Mezo. Unbeknownst to Izuku, the two meet again during the Provisional Hero License Exam where Izuku believes her to be Camie Utsushimi, a student from Shiketsu High School. This encounter only raises Himiko's interest in the boy, as she notes that their interest in each other seemed to be mutual. Izuku is surprised by her fighting abilities, but finds her to be a somewhat scary person the more she interacts with him.

Despite Himiko being a villain, Izuku actually goes out of his way to save her from harm, albeit she was disguised as Ochaco. Being saved and carried to safety in a princess carry by her love interest, Himiko found out that the boy would save somebody even if that person was his opponent. Revealing her Quirk to him but not her real identity, she was curious about how far his good will reached. During the second exam of the Provisional Hero License Exam, Izuku acknowledged her wishing good luck to him.

After the License Exam, Izuku wanted to talk to her again about her stealth techniques, but he was disappointed when he found out she had already left.

During Eri's rescue operation, he ran across her yet again when a disguised Himiko lovingly tried to cut him with her knife. Her Quirk was deactivated by Shota and her identity was revealed, giving Izuku a shock as he was saved by his teacher. Putting two and two together, Izuku figured out that Himiko was likely the same girl that he had sparred with during the license exam confirming suspicions that the League of Villains infiltrated a school other than U.A. and leading to greater interaction between Shiketsu and U.A. High.

In nearly all their encounters, Izuku has been shown to be downright terrified of Himiko's maniacal obsession with him and her deranged personality.

During the final war, Himiko manages to nab Izuku by surprise, and Hikage Shinomori theorizes that Himiko's "love" for Izuku is so strong that his Danger Sense Quirk doesn't register her as a threat, despite Himiko then lunging at him with a knife. Shortly afterwards, Himiko confesses her feelings to Izuku and asks him to be her boyfriend, much to the young hero's shock, confusion and embarrassment. It is revealed here that during all their encounters, Izuku never once imagined that she liked him. The two then share what their perceptions of a couple are, with Izuku saying that they're supposed to do things like hold hands and go on dates, while Himiko says she wishes to become exactly like her lover.

After Himiko shares her feelings with him, Izuku responds by saying that he can understand her wanting to become someone else and compares it to how he admired All Might as a hero, but says that he can't understand wishing to hurt someone to achieve that. Izuku's response turns Himiko off however, believing that he's rejecting her like everyone else. This causes Himiko to forgo her feelings towards Izuku and attack him for real.

Muscular
Izuku meets the villain when the latter nearly kills Kota. Muscular expresses surprise to recognize Izuku and told him that he has orders to kill him while Izuku resolves to face him alone. In their fight, Muscular takes glee in tormenting Izuku who pushed his body and Quirk to their limits. Izuku was also horrified to learn from Muscular that Katsuki is also a target for the League and to learn Muscular is the same villain who killed Kota's parents, which installed his dislike of Quirks and the hero society.

Overcoming his internal struggle, Izuku fought back harder and pushed him back, leaving Muscular surprised and impressed. Muscular took the time to fight all out and overpowered Izuku but he is saved by Kota who distracts him enough for Izuku to use One For All at 1,000,000%. With a combined Delaware Detroit Smash, Izuku is able to break apart Muscular's muscle fibers and send him flying deep into the rock wall, finally defeating the villain.

Deku reunites with Muscular several months later, stopping him from crushing Grand to death. As he holds Grand's unconscious body, Deku somberly remarks how his Danger Sense was running wild and it made sense Muscular was responsible, getting ready to fight him a second time. During their second battle, Izuku makes an attempt to reach out to Muscular and questions his destructive behavior and why he's a villain, even calling him by his real name: Goto Imasuji. Muscular responds that he simply wishes to cause bloodshed so he can die with no regrets and tells Deku not to waste time by trying to sympathize with him. After realizing that Muscular could not be reasoned with, Deku overcomes Muscular's attacks and defeats him.

Muscular was one of the last villains Izuku had defeated before getting his Provisional Hero License and gives him a sign on the bodily damages done onto his body if he exerts himself. This also causes him to develop a new fighting style with his kicks. He's also the first known villain that Izuku fought after leaving U.A. High and choosing to fight villains on his own.

All For One
While he and Izuku went a long time without directly interacting, All For One has made it his mission to hunt down every One For All wielder he can find in an attempt to steal the Quirk and make his brother, the original user, become one with him. When Izuku became the ninth and final user of One For All, it makes All For One his most dangerous foe alongside Tomura, as he inherits him as a nemesis by accepting All Might's power.

Once All For One deduced that Izuku was All Might's successor, he prepared to crush the boy's heroic spirit with an all-or-nothing plan to destroy him and acquire One For All at last. During his time in Tartarus, All For One lost interest in All Might and moved on to Izuku, fantasizing about tormenting him. Izuku, on the other hand, knew there was a chance he'd have to go up against One For All's mortal enemy someday even if the details of the supervillain's plan wouldn't be deduced until months after his imprisonment.

Upon witnessing All For One in the flesh, Izuku felt overwhelming fear, seeing visions of him and his friends dead by his hands. Izuku's feelings toward All For One became extremely spiteful near the end of the Paranormal Liberation War, when the latter takes over Tomura's body and stabs Katsuki, following it up with dismissing the efforts of all the heroes trying to stop Tomura as "pointless". Enraged, Izuku lost his calm and went straight toward Tomura/All For One, leaving him vulnerable to getting One For All stolen.

In the vestige world, All For One mocked Izuku's altruism as a weakness and claimed that All Might made a mistake choosing him as a successor. Yoichi and Nana, however, fought back against him, rebutting that Izuku's perceived weakness is exactly why he was chosen for this power. All For One fails in stealing One For All, and while he acknowledges Izuku as a threat to his plans, he is still dismissive of the young hero.

All For One finds Izuku to be predictable, and exploits this quality to try and break Izuku's spirit. He anticipated that Izuku would reach out to Lady Nagant, so he detonated her using the bomb quirk he'd planted into her in secret. He also left a video message at the former Creature Rejection Clan hideout when the heroes investigated it, telling Izuku that society will always exclude certain people and label them villains, so he is fighting an endless and ultimately pointless battle. All For One's manipulation makes Izuku paranoid to the point that he doesn't try to reach out to other villains he sends his way and begins working alone, making civilians fearful of the hero. His attempts to exhaust and isolate Izuku were thwarted when Class 1-A brought him back to U.A., though he shrugged it off.

Izuku's hatred toward All For One would grow further when he learns that he forced Yuga Aoyama to become a mole for him, endangering the students' lives numerous times. He and his classmates become newly determined to defeat All For One in the coming battle to decide the fate of the world. He and Aoyama ended up drawing him out to a secluded parking lot, whereupon All For One summoned his army of villains in a moment of arrogance and allowed the heroes to spring their counterattack using Warp Gate.

Upon encountering each other again at the floating U.A. High School, All For One jeered at Izuku over the death of Katsuki and the heroes' devastating injuries. Izuku once again lost control of his emotions and was in severe danger of All For One breaking his spine until Mirio calmed him down, informing him that everybody else was still alive and that Katsuki could possibly be revived by Edgeshot. Remembering Banjo's words about controlling his anger, Izuku was able to keep his cool and prepared to fight, asking All For One if Tomura still remained after his forceful merger with him.

All For One, while unaware Izuku was trying to save Tomura, still sensed he had a plan to defeat him that involved the young man, so he bluffed by saying Tomura was gone and that he was the dominant personality. He was quickly proven to be lying by Mirio, prompting him to lunge at Izuku in another attempt to steal One For All, knowing his control over Tomura weakening meant his window to take back the Quirk was dwindling. However, Izuku had unlocked Gearshift, which allowed him to move far faster than Tomura's body afflicted by Erasure could keep up with. All For One was left stunned and unable to move by Izuku's attacks, expressing his petty hatred for him and the heroes before insisting he hadn't lost just yet, vowing that victory or defeat for heroes and villains would be decided very soon.

Overhaul
While interning with Sir Nighteye, Izuku learned of the villain and his connection with the Yakuza. Not too soon, Izuku meets him in person when Eri ran to him for help and Kai arrived shortly after. Izuku immediately recognized him and was nervous to find him so easily, though Mirio helped him to maintain his cover and the villain seems doesn't appear to notice they are aware of his identity. Izuku wanted to question him on his treatment of Eri, and Overhaul appeared to be ready to attack, but Eri runs back to him.

While the heroes were doing investigations, Izuku and Mirio both agree they have to stop Overhaul and save Eri from him.

Izuku went beyond his limits with One For All by using 100% and having Eri continuously rewind the damage done to his body. In the struggle, Izuku and Kai were both relentless but Izuku emerges as the victor. Despite his victory, Izuku was nearly killed by the spiteful villain but Eri saves him and Overhaul is left defeated.

Overhaul is the first major villain Izuku fought after he obtained his hero provisional license, though Izuku had help from Eri to defeat him.

During Izuku's battle with Lady Nagant, he is shocked upon seeing Kai present, yelling at the former Pro Hero that she has to take him to his boss like she promised. Despite their past, Izuku uses Faux 100 Percent to zoom through the air and save his old enemy from being shot, saying that they'll talk later. Following the aftermath of the battle, Izuku coldly addresses Kai and remains contemptuous towards him for all the harm he inflicted upon Eri. Upon seeing Kai in a broken and remorseful state however, he agrees to honor Nagant's deal and take him to see his boss should he apologize to Eri as well.

Stain
Stain respects Izuku's reasoning to be a Hero and sees worth in letting Izuku live. Izuku, on the other hand, saved Tenya from Stain after intervening in the man's attempt to kill his friend. Izuku impressed Stain with his will to defend his friend and efforts to defeat him, which was something he deemed worthy as a hero. With the help of Tenya and Shoto, Izuku managed to defeat the villain.

When Izuku was captured by one of the Nomu-like creatures, Stain was the one who saved him, as the latter expressed shock at this act and was frightened by Stain's speech and aura before he fell unconscious. While Izuku does not approve of Stain's nihilistic methods, Izuku respects Stain for living according to his ideals and never giving up on achieving his ideal world, also comparing the respect they both have for All Might.

Because of their encounter, Spinner prevented his comrade Magne from killing Izuku declaring that he was the person that Stain saw fit to save thus being a man worthy of the title of a true hero.

Gentle Criminal
Izuku first saw him on the internet and was confused by his crimes even wondering about his intentions.

Izuku unintentionally met him in person after accidentally bumping into him outside of school when getting supplies. Initially, Izuku did not recognize him until he heard his voice and remembered his habits. Izuku begged Gentle not to attack the festival, as the villain saw Izuku as an obstacle that had to be removed, but after learning that he was a student of U.A. high school he developed an interest in him.

As they fought more, Izuku was knocked down many times but wanted to honor his promise to Eri. His tenacity caused Gentle to gain a begrudging respect for him and steadily confided in him more of his past. After he lost the match and hearing of Izuku's dream, he treated the boy as an equal and told him to keep moving forward. Izuku still treated him like a threat and remains hostile to him, however, as they fought and after hearing of Gentle's past, he treated him with more respect and care, even stating he wouldn't laugh at his ambitions.

After defeating Gentle, he remained worried about him, even after being blasted into the air by him. Izuku later reasoned that had he not met All Might, he might have well become someone like Gentle, seeing the villain as a dark reflection of himself.

When conversing with the previous One For All users, Izuku notes on how he never really understood why the villains he fought before chose to walk down that path, and when wondering if things could've ended differently if he'd understood what made them villains, a flashback of Gentle and La Brava is shown, demonstrating the great impact his battle with Gentle had and how it made him see villains as people.

Gentle is the first villain Izuku officially defeated on his own, with no outside help.

During the Final War, Izuku was left completely surprised to find out that Gentle suddenly appeared to help the Heroes in preventing the U.A. fortress from plummeting to the ground.

Lady Nagant
Izuku learns about Lady Nagant from Hawks following the end of the Paranormal Liberation War, as Hawks advised him to run from her should he encounter her. Sure enough, due to All For One liberating her and tasking her with capturing him alive for him, he ultimately ends up clashing with her, with Izuku hoping to force her to tell her where All For One is hiding. During his fight with her, he asks why she is working for All For One when she used to be a Hero herself, and listens to her story of how she worked as an assassin for the Hero Public Safety Commission and made several people "disappear" to preserve the image of their Hero Society. He tells her that he understands her points of view and knows that the world they live in isn't as black-and-white as it may seem, but despite knowing he was ignorant of all of that, he still feels like he needs to extend his hand to those who need it.

After he defeats her, he saves her from falling out of the sky and points out that the bullet that she fired at Kai Chisaki to try and get him to drop his guard was off by a bit and that if she was truly loyal to All For One, she would have just shot him immediately rather than give him a chance to surrender. As a result, he tells her that he believes she still has the heart of a Hero and asks her to join his side. Lady Nagant is impressed with Izuku and is about to call him the real deal, when All For One detonates her body. Her body explodes and Izuku screams in horror.

He was relieved that she survived and got more information from her before she fell unconscious from her wounds, but the incident served as a sore spot for him after. All For One correctly deduced that dangling her in front of him to make him try to save her was the surest way to stoke his fury, provoking him into coming after him alone. This tactic actually works for a while, and proves how much of an impression Lady Nagant left on him

Later, he thought back to her when speaking his friend Yuga Aoyama, who had been exposed as a traitor, to express his faith that he could still be a hero and make up for selling information to All For One that had hurt the class. Nagant had helped Izuku realize that anybody can fall victim to circumstance, and that poor decisions are not always reflective of an individual.

During the Final War, just as Tomura was about to activate his Decay, Lady Nagant fired a bullet straight towards him, splitting his right arm off. This act has left Izuku completely surprised, knowing that another former enemy of his has now become an ally.

Predecessors
The past users of One For All and Izuku's predecessors. Izuku senses their presence for the first time during the Sports Festival, when they briefly intervene to save him from Hitoshi's brainwashing. Months later, Izuku has a dream where he meets the predecessors properly and is shocked to learn that they are all conscious. According to All Might, Izuku is the first user of One For All to be able to communicate with the predecessors. The predecessors have difficulty communicating with Izuku, but they support him in his journey. It's to note after the fight with Nine, all the predecessors chose to stay with Izuku after he transferred the power to Katsuki, recognizing his willingness to protect others, even if it meant losing the power. Almost all the vestiges of the previous predecessors are seen welcoming him as one of them. Despite the fact that All Might no longer has the power, he can still sense his vestige within the vestige world. The predecessors are shown to care for Izuku, as the inheritors of One For All tell Deku not to push himself because of his injuries. They all share the one common enemy: All For One, the arch-nemesis of One For All.

Yoichi Shigaraki
Sometime after Izuku inherited One For All, All Might narrates him the origins of One For All and the story of All For One's younger brother, Yoichi the first user of One For All.

After the fight with Endeavor and Hood, Izuku was exhausted after training he later went to sleep. Later, Izuku woke up to find himself in the vestige world, seeing all of the previous wielders of One For All. After seeing the history with Yoichi and his brother in the past, Yoichi wanted to show more of his history with his brother but at the time Izuku was only at 20% of his power. Yoichi also recognized him as the ninth user of One For All.

Later during the Paranormal Liberation War, after Tomura awakened with the All For One Quirk, Yoichi warned him that Tomura has awakened and his growing power and to stop him, when Tomura attempted to steal One For All from Deku. They appeared in the vestige world, where All For One was a half fusion with Tomura, and the two combined their power in attempt to steal One For All. After Izuku fell and Nana appeared to assist him, Yoichi appeared again, talking how his older brother always took advantage of people's weakness. He later assisted Nana to stop All For One and Tomura from stealing One For All. He deemed Izuku worthy of wielding One For All and said that they would follow him.

After the battle in the Paranormal Liberation War, Izuku fell into a coma, and he woke up in the vestige world, where he found himself in a room filled with chairs and all the predecessors except the second and third, who have their backs facing Izuku. Yoichi explains to Izuku what he and the rest of the users have gathered about the true nature of One For All based on the research Toshinori gathered and what his vestige told them. After Izuku said that he will try to save Tomura, Yoichi looked at Izuku with a smile.

The younger Shigaraki deeply respects and approves of Izuku as, like him, Yoichi has a strong sense of justice and responsibility to others while desiring to use his abilities to protect. Yoichi even goes to far to say they he is glad that Izuku of all people was chosen as the next successor.

The Second User
Izuku and the second user did not interact much prior to the end of the Paranormal Liberation War. When Izuku went into a coma and found himself in a room with all the predecessors in a chair expect for the second user who was standing in front of a wall. Yoichi told the second user to play nice and to help Izuku. The second user was initially unwilling to help Izuku, viewing his ideals as foolish and not acknowledging him as a successor because he had never experienced the harsh times during All For One's height of power, believing he doesn't understand the responsibility of how much One For All means to end the war with All For One. However, after being convinced by Yoichi, the second user decided to help Izuku alongside the rest of the predecessors to end the fight with All For One.

When Izuku says that he has to keep moving, the second user agrees with Izuku, stating that the path he is choosing is the correct path, especially in this particular situation. The second user of One For All was also supportive of Izuku because he reflects about how if there was anyone who could bolster Izuku, it would be those who share his resolve, can match his pace, and are willing to run alongside him, like his former classmates of Class 1-A.

The Third User
Izuku and the third user did not interact much prior to the end of the Paranormal Liberation War. When Izuku went into a coma and found himself in a room with all the predecessors in a chair expect for the third user was standing in front of a wall. Yoichi later told the third user to play nice and to help Izuku. Like the second user, the third user did not approve of Izuku or his ideals, even refusing to acknowledge him as a successor because Izuku will never understand the responsibility of how much One For All means to end the war with All For One. However, after being convinced by Yoichi, the third user decided to help Izuku alongside the rest of the predecessors to end the fight with All For One.

Hikage Shinomori
During the climax of the Paranormal Liberation War, after witnessing Tomura stab Katsuki, Deku unknowingly awakens Hikage's Quirk: Danger Sense. Though Izuku only knew Hikage from the notes taken by All Might about the previous holders, he formally meets Hikage along with the other users while he is in a coma from the aftermath of the Paranormal Liberation War. Hikage introduces himself to Izuku, explaining his past, his decision to train to strengthen One For All, and the cause of his death. When learning that Hikage died at the age of fourty which he considered to be "old age" and that due him have a Quirk that to his life force being drained by One For All, Izuku is shocked and saddened that Hikage's life was ended so soon.

Daigoro Banjo
