Katsuki Bakugo

Katsuki Bakugou (爆豪勝己) is a student of Class 1-A and a deuteragonist of the series.

Appearance
He has ash brown spiky hair and orange eyes.

His hero costume is composed of a black sleeveless V-neck shirt with an orange X with the top half boarders his shirt collar. His costume also has a seemingly metallic neck brace fashioned and used as a collar with with three holes in both sides, sleeves reach from within his large grenade-like gauntlets to his biceps. His belt, which also carries grenades, holds up his baggy pants with knee-guards. He occasionally wears his hero mask that has large flare-shaped cloth

Personality
Katsuki is a very crude and aggressive person that has a tendency of bullying Izuku Midoriya, who he also treats in some ways as a rival.

Brutal and bloodthirsty, he smiles eerily when he's put into battle. While battling, his personality reflects his fighting style. His brutish way of fighting is shown through the Battle Trial: mercilessly assaulting Izuku and having no regard for nearby objects, merely destroying them with his power. Despite this, he's quite talented in fighting, able to use his Quirk to not only destroy, but to maneuver around the battlefield.

While not the most mentally stable hero-in-training, nor having the image of one, he knows who his enemies and allies are. Cold to his allies, though not to the extent of friendly fire, but colder and brutal to his enemies. As the series progresses, his outbursts become less aggressive, usually becoming more comical, as he mostly gets angry at even small things like teasing. With that in mind, Katsuki seems to mature slowly, but is still quite cold and distant.

He has a superiority complex and wants to be first and the best at everything. He doesn't like when people look down on him, as if they were superior to him; thus, it diminishes his already short fuse. Despite his extreme arrogance, he also thinks of people such as Izuku Midoriya as an obstacle on his path to becoming the greatest hero. Because of his complex, he's implied to be anti-social; He also seems to have bad memory, as he couldn't remember anyone's Quirks despite being in Yuuei for some time, and couldn't remember Eijirou's name. But after his fight with Ochako, he used her name, implying that he remembers the names of people who give him a challenge.

Past
Katsuki and Izuku have lived in the same neighborhood since childhood and thus, were once childhood friends. Izuku looked up to Katsuki for his energy and confidence, while Katsuki himself often picked on him, giving him the demeaning nickname "Deku." After Katsuki gained his Quirk, however, his aggressive tendencies soon turned into heinous bullying; as he was constantly praised for his powerful Quirk, he developed a twisted superiority complex based on powers and thus looked down on Izuku for lacking a Quirk altogether. However, Izuku still considered Katsuki to be his friend, but things would escalate when Izuku tired to help Katsuki when he fell into a hole which Katsuki considered to be an insult as he believed that Izuku made him look like he needed aid from someone who is beneath him.

Entrance Exam Arc
When walking into the front of Yuuei Katsuki sees Izuku also walking in. He confronts him by telling him to get out of his way and walks passed him. Later in the auditorium in Yuuei, he sits next to Izuku and tells him to "shut it" because Izuku is yelling about Present Mic being Examiner. Katsuki then gets mad when Present Mic tells them that they can't attack other examinees, as he really wanted to crush Izuku. Later, during Plus Ultra, Katsuki can be seen destroying multiple enemies.

Quirk Apprehension Test Arc
Katsuki uses his quirk to launch a ball the farthest and become ranked on how long strong and how useful it is. He uses Explosion and launches it. When he sees Izuku Midoriya use his Quirk, he becomes shocked and furious, as he cannot believe that Izuku has a Quirk. He tries to attack Izuku out of anger, but Shouta stops him from doing so.

Battle Trial Arc
Katsuki is teamed with Tenya Iida as the villains team and assigned the mission to stop the heroes team consisting of Izuku Midoriya and Ochako Uraraka. Katsuki ambushes Izuku and uses Explosion on Izuku. Izuku grabs his arm and then throws him on the ground. After Izuku tells Katsuki that he has analysed and taken notes (the same notes Katsuki blew up and threw away in the past) on many Heroes including him. He announces that he is no longer the "Deku" who was a loser, but the "Deku" who's vibe is never giving up, much to Katsuki's fury.

Izuku tries to use the Capturing Weapon on Katsuki's leg, but Katsuki breaks free using his Quirk. Knowing he's at a disadvantage, Izuku retreats in order to think of a strategy.Afterwards, Katsuki finds Izuku and uses his bracer that has been storing up a lot of sweat to cause a huge Explosion, destroying a large portion of the building. However, Izuku manages to survive the blast and calls Katsuki insane for doing that, but a seathing Katsuki demands that Izuku use his Quirk.

All Might tells Katsuki that if he uses another huge Explosion like that he will disqualify him and Tenya, much to Katsuki's anger, but decides to resort to fist fighting. Izuku and Katsuki continue theirfight, with Izuku trying to land a punch on Katsuki, but Katsuki launches himself behind Izuku using an Explosion and uses another Explosion to hit Izuku's back. Katsuki then hits Izuku's right arm, grabs it and throws him into the ground. Izuku is unable to think of a strategy in the midst of battle due to Katsuki not giving him any openings and realizes that Katsuki is simply far stronger than he is. Izuku decides to use his Quirk and informs Ochako to grab onto something. Instead of hitting Katsuki, Izuku aims his Detroit Smash into the ceiling, destroying the fifth floor's ground, but Izuku is forced to take the full brunt of Katsuki's Explosion. Although Izuku was unable to defeat Katsuki, it did distract Tenya long enough for Ochako to grab the fake Nuclear Bomb, allowing both Izuku and Ochako to win, shocking Katsuki.

Katsuki is in disbelief that he lost to Izuku. All Might All Might approaches Katsuki, telling him that its time for his critique. He tells Katsuki that it doesn't matter whether he won or lost, but that he takes one look back, reflect on his experience and move on with life. Katsuki is seen outside school, but Izuku approaches him, telling him that he obtained his Quirk from someone else. Not believing him, Katsuki tells him that he lost fair and square and states to him that he still dreams of becoming the best of the best. All Might then appears before Katsuki, trying to counsel him on self-confidence, although he is told in response by Katsuki that he will surpass him as well, thus All Might decides to leave Katsuki alone.

Ultimate Space & Jams Arc
Katsuki is approached by reporters, asking him if he is the boy from the sludge man incident, but he tells them to get out. Later, in class, Shouta Aizawa reprimands Katsuki, telling him to stop acting like a 7-year old as he is wasting his talent being like that. Shouta then announces that "unfortunately" they'll have to elect a Class President, surprising them but at the same time making them happy as Yuuei "is finally starting to look like a school". Like most people, he voted on himself. At the end of the class elections, Katsuki is angered to see that people voted for Izuku.

Some days later, Shouta announces to Class 1-A that he, All Might and a third person will supervise them on a test of the abilities of the heroic foundaments, in Rescue Training. On the bus on the way to the U.S.J., Tsuyu says Katsuki won't be very popular because he's always stressed. After he realizes what she said, he screams at her in anger, effectively proving her point. He then listens expectingly to No. 13's explaination about Quirks and the U.S.J., along with other students and Shouta.

When the villains appear at the U.S.J, Katsuki, along with Eijirou, tries to attack Black Mist, but he uses his Quirk to warp them both to the Ruins Zone area of the U.S.J. Together, they easily defeat the villains there. He and Eijirou discuss what to do next, with Katsuki saying that he is going to fight Black Mist since he is the villains' escape route. One of the villains try to attack Katsuki from behind, but Katsuki easily stops and defeats the villain. Katsuki is about to leave, but Eijirou decides to go with him having started to believe in him.

Katsuki then appears before Black Mist, striking him with a punch and then restrains him. His effort along with Shouto allows All Might to escape from Noumu's clutches. Katsuki is forced to let go of Black Mist when Noumu tries to attack him, evading him in the process. After the Villain Alliance is defeated, Katsuki is seen with his class.

Sports Festival Arc
Katsuki is seen confronting a crowd of students that is blocking his path, angrily telling them to go away, which angers one of the students from the General Education Department. On the day of the Sports Festival in the waiting room, Katsuki sees Shouto confront Izuku. After Izuku declares that he will do his best, Katsuki is seen grunting quietly. Katsuki then walks out with his class to the Sports Festival.

After being called to the stage as Class 1's representative, due to placing first in the Entrance Exam, he calmly declares that he will place first, which causes the classes from the other departments to rebuke at him. After the Obstacle Race starts, Katsuki avoids Shouto's ice and boosts himself ahead with his Explosion, using it to jump over the humongous robots and head to the next obstacle which is the Fall.

Katsuki manages to get across the Fall and after entering the land mine field, he blasts ahead to the lead with his Explosion since the land mines don't mean anything to him thanks to his Quirk and uses Blast Rush Turbo to propel himself forward, which allows him to catch up with Shouto who is in the lead. He asks Shouto if he issued his war declaration to the wrong rival. Both he and Shouto get into a brief scuffle for the lead position. Katsuki then watches Izuku flying towards him and Shouto. Izuku manages to pass them, which makes Katsuki angry. Katsuki manages to catch up to him, but Izuku uses his metal plate to blow dust into his eyes, stopping him momentarily, allowing Izuku to place first. Katsuki then crosses the finish line, placing third, allowing him to participate in the second event which is the Human Cavalry Battle but is angry that once again Izuku beat him. Many of his classmates want to team up with him for the Human Cavalry Battle, but asks what their Quirks are (having seemingly forgotten), much to their surprise. Eijirou asks Katsuki to team up with him, saying that only he can withstand the recoils of his explosions and declares that they will get Izuku's ten million points, which sparks Katsuki's interest. Katsuki eventually teams up with Hanta and Mina as well.

After the Human Cavalry Battle begins, Katsuki jumps into the air and tries to attack Izuku with an Explosion, but Fumikage uses his Dark Shadow to block it. Hanta uses his Quirk to catch Katsuki so that he can land safely back on his team's formation. After Neito takes his headband without trouble and mocks him for always being attacked by villains every year, this makes Katsuki enraged and he then tells Eijirou that their plans have changed; before they take Izuku's ten million points, they will defeat Neito's team first. Eijirou tells him that if he gets angry they won't be able to recover their points, but Katsuki says "he's madly calm". Katsuki battles against Neito but Neito copies and uses Katsuki's Quirk against him. Katsuki tries to attack Neito again, but Neito copies and uses Eijirou's Quirk to block him and shrugs him off. After Neito tells him not to become enraged since he fanned the flames, Katsuki says that he will be number one. Katsuki jumps off his team's formation and attacks Neito. Kousei uses his Quirk to create a wall to block Katsuki. However, Katsuki punches through the wall and breaks it, grabbing two of Neito's headbands in the process, surprising Neito who could not counter attack due to having his guard down. Hanta uses his Quirk to reel Katsuki back onto their formation. Katsuki then orders his team to attack Neito; having Hanta use his Quirk and has Mina use her dissolving fluid. Katsuki and his team ride on Mina's fluid to reach Neito's team faster thanks to Hanta reeling in his tape. Katsuki attacks Neito for the final time and grabs his last headband, which places their team at second place. Katsuki, however, wants to collect the ten miilion point headband and goes with his team to where Izuku's team and Shouto's team are. In the final ten seconds, Katsuki's uses his Quirk to launch off his team's formation and into the air. However, he has trouble deciding which team to attack and before he can come to a decision, the Human Cavalry Battle ends. Katsuki lands on the ground, annoyed that he could not get the ten million headband. However, Katsuki's last minute actions allowed him and his team to reach second place, allowing them to participate in the final event. Katsuki is seen secretly overhearing Shouto explaining his story to Izuku, with a somewhat surprised expression on his face after hearing it. The final event is a tournament event and Katsuki's opponent in the first round is Ochako Urahara, with Katsuki wondering who Ochako is. Katsuki watches Izuku's battle with Hitoshi and becomes nostalgic when Izuku throws Hitoshi over his shoulder, remembering that Izuku did the same action to him in the Battle Trial. After Denki says to Katsuki that Izuku used the same overthrow he used on him, Katsuki tells him to shut his mouth. Katsuki walks to the ring to face his opponent, Ochako, in his first round match. Before the match begins, Katsuki tells Ochako that if she is going to withdraw, she should do it now. However, Ochako refuses to draw and the match begins; Ochako runs forward to attack and Katsuki retaliates by sending an explosion directly at Ochako which hits her. Katsuki, thinking Ochako is on the ground, grabs her, but sees that he has grabbed her jacket while Ochako sneaks behind him. Ochako prepares to attack him from behind, but Katsuki, seeing that she is behind him, uses an explosion against Ochako and blows her away, damaging her. Ochako tries to attack him, however, Katsuki manages to be quicker than her and hits her with another explosion. Seeing that she is still standing, Katsuki attacks Ochako with two more explosions in an attempt to knock her out, but Ochako proves to be quite resilient (despite taking a huge amount of damage). When Katsuki attacks Ochako with another explosion, the crowd start booing at Katsuki for toying with his opponent. However, Shouta defends Katsuki, saying that he is on guard and because he is doing everything to win, he cannot afford to let his guard down. Ochako, tired and battered by Katsuki's explosions, thanks him for being on guard as it allowed her to prepare her plan; to fire a shower of rubble against Katsuki (who never realized what she was doing) from above. The meteor shower of rubble descend on Katsuki while Ochako runs towards Katsuki. However, Katsuki creates a huge explosion which not only destroys the meteor shower of rubble but also blows Ochako back. Afterwards, Katsuki says to Ochako that he was aware that she was hanging around with Izuku and knew that she had something up her sleeve.

Katsuki prepares to attack her as he states that the real fight starts now, while saying her last name, but Ochako collapses onto the ground, badly injured and drained of stamina due to Katsuki's attacks. Because Ochako is unable to move, she is declared defeated and Katsuki is declared the winner, thus he moves on to the next round. Katsuki leaves the ring and walks up the corridor where he sees Izuku. As Izuku tries to leave, Katsuki accuses Izuku of giving Ochako strategies to use against him, irritated that Izuku caused him trouble. However, Izuku replies that he didn't give Ochako any strategies and it was Ochako that devised the strategies herself to use against him, going on to say that if anyone was tossing him around, it was Ochako that was tossing him around, much to Katsuki's anger. He then goes to the stadium to sit with his class. As Hanta and Tsuyu comment on his match, Katsuki tells them to be quiet and goes to sit down on his seat. When Denki says that he was able to blast a frail girl with no qualms, Katsuki replies that there was nothing frail about her. As the match between Izuku and Shouto begins, Eijirou returns to sit down with his class. Eijirou tells Katsuki that he is next, to which Katsuki replies that he will beat him to death. After Eijirou states that both he and Shouto can send powerful attacks without breaking a sweat, Katsuki tells Eijirou that Quirks are physical functions similar to for example like running; if you run too much, you will run out of breath and as such Quirks have limits as well and comments that Shouto also has a limit to his Quirk.



Katsuki says to himself that he too has a limit on how much power he can use and as such is the reason why he added the Grenadier Bracers to his hero costume to amplify his Explosions. Katsuki continues to watch the battle between Izuku and Shouto. Katsuki notes that Shouto's movements have become sloppy, thinking that the reason behind it is because of his body's right side forming frost. Katsuki compares Shouto's ice limit to that of a video game's MP. Katsuki faces his opponent, Eijirou, in his second round match. During the match, both Katsuki and Eijirou hit each other directly with their Quirks but Eijirou's tough skin dampens Katsuki's Explosion while Katsuki is injured by Eijirou's hardened punch. Katsuki evades Eijirou's hardened swipes unable to land an Explosion against him. Katsuki eventually managed to hit and injure Eijirou with an Explosion. Katsuki realizes that Eijirou's Hardening weakens through continuous strikes. Katsuki attacks Eijirou with a continuous barrage of Explosions that not only breaks through Eijirou's Hardening but badly injures Eijirou as well. Eijirou is knocked out by Katsuki's Explosion barrage and Katsuki is declared the winner, allowing him to advance to the third round (semi-finals).

Katsuki faces his opponent, Fumikage, in his third round match. Katsuki's fierce fighting style and Quirk type advantage forces Fumikage to go completely on the defensive, not even giving Fumikage any room to counter. However, Fumikage's Dark Shadow does keep Katsuki at bay which annoys Katsuki. After hitting Dark Shadow with two Explosions, Katsuki jumps into the air and lands another Explosion on Dark Shadow. Fumikage orders Dark Shadow to grab Katsuki, but Katsuki counters Dark Shadow with an Explosion which stops Dark Shadow. Katsuki leaps over Dark Shadow and gets behind Fumikage. Katsuki prepares to a move called Stun Grenade as Dark Shadow tries to protect Fumikage. However, Katsuki successfully executes Stun Grenade before Dark Shadow gets into a defensive position. Thus, Katsuki's Stun Grenade effectively hits Dark Shadow and Fumikage. After the smoke clears, Katsuki has pinned down the injured Fumikage. Katsuki tells Fumikage that its his fault for telling people about Dark Shadow's weakness but admits that it wasn't a fair matchup to begin with. Fumikage surrenders, making Katsuki the winner and allowing him to advance to the final round where he will face Shouto Todoroki.

After his match with Fumikage, Katsuki barges into a waiting room, but finds out that he entered the wrong room. Katsuki sees his opponent, Shouto waiting in the room. Shouto doesn't pay much attention to Katsuki, much to Katsuki's annoyance. Katsuki complains about Shouto's attitude towards a fellow finalist. Shouto continues to ignore him until Katsuki uses a small Explosion on the table to get his attention. Shouto says to Katsuki that Izuku is the type of person who is compelled to drag out peoples' problems and help them. Shouto asks Katsuki, as Izuku's childhood friend, if Izuku has always been the type of person compelled to help people's problems. Katsuki remembers how Izuku tried to help him in their childhood, which infuriates Katsuki. Furious, Katsuki angrily kicks the table over, telling Shouto that he doesn't care about Izuku and doesn't care about Shouto's problems or feelings. Before he leaves, Katsuki tells Shouto to give everything he's got and as he walks out of the waiting room, Katsuki says that he will make Izuku bow to him once he has reached the top.

Katsuki faces his opponent, Shouto, in the final round. As the match begins, Katsuki grins with satisfaction as after his match with Shouto he says that he is going to be the best. The final match begins with Shouto attacking Katsuki with a huge pillar of ice. However, Katsuki thaws himself out with an Explosion. After breaking out of Shouto's ice, Katsuki uses some Explosions to somersault himself into the air. While in the air, Katsuki grabs Shouto's hair and shirt and throws Shouto onto the ground, but Shouto creates an ice wall behind himself to prevent himself from being thrown out of the ring. Katsuki immediately attacks Shouto with an Explosion but Shouto grabs Katsuki's arm, throws Katsuki into his wall of ice and in the process throws himself out of Katsuki's way. Katsuki becomes angry at Shouto for not using his full power and yells that there is no point in beating anyone if they don't use their full power. Katsuki says that he can't prove himself if he defeats Shouto too easily and tells Shouto to not stand in front of him if he doesn't plan on fighting to win. Katsuki dashes into the air and creates two explosions in his hands. He spins himself around and after doing so, Katsuki attacks Shouto with his move Howitzer Impact; an explosive tornado which hits Shouto. Katsuki lands on the ground after using Howitzer Impact. Katsuki sees that Shouto is out of the ring. Furious, Katsuki immediately gets up and grabs Shouto by his shirt, dissatisfied with Shouto's performance. Before he can do anything, Katsuki is knocked out by Midnight's perfume. Because Shouto went out of bounds, Katsuki is declared the winner of the final match and due to winning the tournament event, Katsuki is also declared the winner of Class 1's Sports Festival.

At Yuuei's closing ceremony, Katsuki is on the podium for his first place award. However, due to being furious at Shouto and to prevent him from unleashing his fury at him, Katsuki is fully restrained; his arms and hands restrained with locks, his body wrapped around a wooden log, chained to the podium and a face mask. All Might goes to Katsuki to give him his medal for achieving first place and while taking off his face mask compliments him on his foreshadowing. Katsuki angrily tells All Might is an expression of fury that he doesn't deserve to be Number One as he doesn't acknowledge it. All Might tells Katsuki that society will still acknowledge him as being worthy of Number One even if he doesn't. All Might gives Katsuki his medal but Katsuki instead angrily grabs it by biting it.

After the closing ceremony of Yuuei's Sports Festival is finished, later the next day at noon, Katsuki is at home angrily brushing his teeth, still unable to let go of his fury.

Current unnamed Arc
Two days after the Sports Festival, Katsuki is in class. During the Hero Informatics period, Shouta shows the Pro Hero nominations which reveals that Katsuki received 3,556 Pro Hero nominations the second highest in the class. Afterwards, Class 1-A has to decide on Hero names. Katsuki writes down and shows his Hero name which is King of Explodo-Kills.However, Midnight asks him to change his name. As Katsuki changes his Hero name, Izuku reveals his Hero name to be Deku which makes Katsuki angry. After Izuku is finished presenting his Hero name, Katsuki changes his Hero name to Baron of Explodo-Kills to which Midnight replies that won't do.

Powers and Abilities
Katsuki is extraordinarily powerful, being able to fight on par with Izuku even when the latter is using his Quirk as well as having superior intelligence, and even Pro Heroes (such as All Might) mentioned several times his great potential and battle-sense. Shouta Aizawa stated that in battle Katsuki shines his brightest.

He's also very smart and strategic, as he was able to figure out Black Mist's Quirk weakness.

Quirk
"Explosion" - Katsuki's sweat is nitroglycerin-like, and Katsuki can use it to create explosions. The more Katsuki sweats, the stronger his explosions become. So far, the signature use of his Quirk is through his hands; usually between punches or to shroud his fist with explosive energy. It is unknown if he can create explosions from any other part of his body. His most powerful Explosion so far (without the need of the Grenadier Bracers) was able to completely destroy Ochako's meteor rubble shower, knocking her down onto the ground at the same time and caused a shockwave that was felt throughout the stadium.

Moves

 * "Blast Rush Turbo (Move)": Katsuki throws his hands backwards and then causes an explosion in his palms, to propel himself. This move was first used during the 50 meter dash of the quirk apprehension test in Chapter 6. This move can also be used to achieve a pseudo form of flight, as Katsuki used this move to fly over the giant robots during the Obstacle Race during the Sports Festival.
 * "Stun Grenade (Move)": Katsuki creates a sphere of light with his hands. The sphere of light implodes, causing an explosion around Katsuki, damaging anything in Katsuki's vicinity. This move was first used in Chapter 42.
 * "Howitzer Impact (Move)": Katsuki dashes into the air and creates two Explosions in his hands. While in the air, Katsuki spins himself around, building up momentum for his Explosions. After spinning himself around and gathering momentum for his Explosions, Katsuki fires an Explosive tornado at his opponent. This move was first used in Chapter 43.

Equipment and Weapons

 * "Grenadier Bracers": An adjustment added to Katsuki's hero costume that stores his nitroglycerin-like sweat. Once filled he can pull the grenade pin in order to release a large blast. As shown when he fought Izuku in All Might's Heroes vs. Villains test. It has enough explosive power to destroy all parts of the building within its blast radius. This equipment was first used during the Battle Trial arc in Chapter 9.

Izuku Midoriya
Katsuki and Izuku were playmates during their childhood, but Katsuki always considered the latter as a hindrance, an obstacle, in his path to become the greatest hero. Although he felt superior to Izuku, there are times where he feels that Izuku was making fun of him, such as when Izuku saved him, or due to Izuku "hiding the fact that he had a Quirk all this time". As of now, Katsuki sees Izuku as his arch rival and has always shown hostility towards Izuku whenever he interacts with him.

Eijirou Kirishima
Katsuki seems to get along well with Kirishima, despite their differing personalities. Eijirou looks up to Katsuki's explosive attitude, often interpreting his actions as manly, something he appears to highly value, but he's not above getting frustrated with Katsuki's tendencies, seen when he tries to get him to cool off after Monoma insulted them during the cavalry battle. Although Katsuki at first didn't give him much attention, he seems to appreciate their Quirks' compatibility with each other, as he accepted Ejirou's proposal to form a team during the Human Cavalry Battle. He was also unable to remember Eijirou's name, calling him "hedgehog hair" (despite having spiky hair himself), which bothered Eijirou.

Shouto Todoroki
Katsuki sees Shouto as another rival and someone that he needs to defeat to become Number One. When Shouto and Izuku talked to each other after the Human Cavalry Battle, Katsuki secretly overheard Shouto's backstory, with a seemingly surprised expression on his face after hearing it. Despite hearing Shouto's tragic backstory, Katsuki showed no sympathy towards Shouto and even said that he didn't care about Shouto's problems or feelings. After their battle in the Sports Festival, Katsuki despises Shouto due to him not giving him a battle worthy enough of being called Number One. Katsuki's hatred of Shouto caused him to be fully restrained during the closing ceremony of the Sports Festival to prevent him from unleashing his fury onto Shouto.

Ochako Uraraka
Katsuki hasn't interacted with Ochako, most likely due to her being friends with Izuku. They first interact during the Sports Festival tournament when they have to face each other in the first round, with Katsuki in his own way had offered Ochako the chance to withdraw as he will show her no mercy even if she is a girl. Before the end of their match, Katsuki used her last name before their final clash, indicating that Katsuki respects Ochako's perseverance (as he usually doesn't remember peoples' names). He even went out of his way to say that Ochako wasn't fragile, even when his classmates said that she was.
