Kota Izumi

Kota Izumi is the nephew of Shino Sosaki and the son of the now deceased hero team Water Horse.

Appearance
Kota is a small boy, comparable in height to Minoru. He wears a buttoned shirt, black shorts and black boots. Kota has short black hair and wears a hat with golden, spike-shaped horns on the front.

Personality
Kota has a cynical and jaded view of heroes. This stems from his parents' deaths, as he felt that they chose their jobs over him and abandoned him. Kota's negative view on heroes has also caused him to despise Quirks and the current society in general, believing that the "corny powers" are responsible for all the misery in the world. However, after Kota was saved by Izuku from Muscular, Kota's jaded view has somewhat changed and he thanked Izuku for saving him.

Kota is shown to be disgusted with indecency as shown with Minoru Mineta's perverted behavior, telling him to learn human decency before aiming to be a hero; he even pushed him to make him fall off the dividing wall in the hot springs after catching him attempting to peek on the girls, and didn't care that Minoru would get hurt from the fall. However, Kota himself is seen having a small nosebleed after accidentally getting a quick glance at the girls of Class 1-A at the hot springs.

History
Two years before the current story, Kota's parents sacrificed themselves to save civilians from a villain. As a result, they died a truly heroic death; Kota's parents were praised and celebrated for their actions befitting true heroes. However, Kota was devastated by his parents' deaths because they meant everything to him. Feeling that his parents abandoned him and chose their jobs over him, Kota started despising heroes. Afterwards, Kota was taken in by the Pussycats, a hero team of which Mandalay, his last known relative, is a part of. From then onward, Kota followed and obeyed Mandalay and Pixie-Bob's orders without question even though he despises heroes.

Forest Training Camp Arc
Kota appears alongside Mandalay and Pixie-Bob when they introduce themselves to Class 1-A. After Class 1-A begin traversing the The Beast's Forest, Mandalay tells him that they are heading back. However, Kota is not enthusiastic about this.

At 5:20 PM later that day, after Class 1-A arrive at the facility, Izuku asks about Kota and wonders if one of them is his mother. Mandalay explains to Izuku that Kota is her nephew and asks him to say hello to Class 1-A. Izuku introduces himself to Kota. Suddenly, Kota punches Izuku in his crotch and begins walking away. Tenya goes to check on Izuku and admonishes Kota for his actions. However, Kota harshly replies that he doesn’t want to be with people who want to become corny heroes and walks away.

During the evening when Minoru attempts to peek on the females of Class 1-A in the hot springs, Kota appears and pushes Minoru down, telling Minoru to train in human decency before aiming to be a hero; Minoru curses Kota as he begins falling back down. The females of Class 1-A thank Kota for stopping Minoru; Kota accidentally looks at the Class 1-A females and falls into the males’ hot springs from shock. Izuku catches Kota using One For All Full Cowl.

Izuku brings the unconscious Kota, who has passed out from the fear of falling, to the facility's office. In the office, Mandalay thanks Izuku for being there to help him. Izuku notes that Kota does not like the concept of heroes and explains that he, along with many others, grew up in an environment where they wanted to become Heroes, and he is surprised that Kota has a dim view of Heroes. Pixie-Bob explains Kota's history to Izuku.

During Class 1-A's training session, Kota silently watches Izuku train with Tora. At 4:00 PM later that day, while watching Class 1-A make their own food from a distance, Kota notes that their training is a waste of time and leaves; Izuku sees Kota while walking back to his class.

On a cliff, Kota is sitting alone. Suddenly, Izuku approaches Kota with a bowl of curry, surprising Kota. Izuku offers the curry to Kota after surmising that he did not have anything to eat. Kota demands to know how Izuku managed to find his secret base, to which Izuku responds that he followed his footprints. Kota harshly tells Izuku that he does not want any of his food or company, and demands that he leaves. Kota finds Izuku training along with everyone else's training to be pathetic because all they want is to brag about their "corny powers." Izuku notes that Kota’s parents were the water-type heroes, the Water Horse; Kota is infuriated that Izuku knows about his parents and surmises that Mandalay told him. However, Izuku tells Kota that he knows their names after hearing about them. Izuku offers his condolences, but Kota doesn't take heed of it. Kota expresses his contempt for the current society of heroes and villains; he is angry that they use their Quirks for violence just to show off and blames Quirks for being responsible for many deaths. Izuku sees that Kota does not only have hatred for heroes, but for Quirks and society itself. Izuku remains silent and becomes sympathetic to Kota's circumstances. Kota demands that Izuku leave. However, Izuku tells Kota a story about his "friend" who was born without a Quirk. Izuku explains that his friend desired to be a hero, but that dream was impossible without a Quirk and he could not accept the reality for a long time, so he tried many different methods to awaken his Quirk. Izuku tells Kota the moral of the story; if you reject reality harshly, the only person getting hurt is yourself. Enraged, Kota orders Izuku to leave and starts threatening him. Izuku apologizes to Kota for not being able to offer any useful advice and leaves the curry on the ground for him. Izuku walks away.

On the night of the Vanguard Action Squad's attack, Kota is confronted by the masked villain. Mandalay communicates with him to ask him to return to the facility and apologize for being unable to help him. The villain Muscular appears on the same cliff where Kota is. The masked villain comments on Kota’s stylish hat and wonders if the boy will trade the hat for the mask he despises. However, Kota begins running away as the villain takes off his mask. The villain uses his Quirk to jump in front of Kota. Kota sees the villain’s face and remembers the news article on his parents' murderer. Muscular has the same simple strength-augmenting Quirk and his most defining feature is the deep scar across his left eye left by the Water Horse duo. Kota realizes that the villain in front of him is none other than the one who murdered his parents. Muscular prepares to attack while Kota cries and is immobilized from fear. Suddenly, Izuku appears and saves Kota from the villain’s attack. Izuku analyses the situation; his phone is broken as a result of tumbling to the ground from saving Kota and he did not tell anyone about his location, thus he does not have any way of communicating for backup. Izuku it his top priority to protect Kota from the villain since he is the only one standing in the villain’s way. With no other options available, Izuku decides to fight Muscular head-on. Izuku tells Kota to not worry because he will save him no matter what; Izuku activates One For All Full Cowl and prepares to fight the villain who murdered Kota’s parents.

Izuku fights against Muscular but is overpowered in offense and speed. Just as the villain is about to finish Izuku off. Kota throws a rock at Muscular. Kota asks Muscular if he tormented his parents just as he is tormenting Izuku. Muscular is surprised that the Water Horse duo had a child and considers their meeting to be fate. Kota condemns the villain for his evil actions. However, the villain criticizes Kota for trying to put the fault on him while admitting that he does not hold any grudges for the loss of his eye. Muscular mocks the Water Horse duo for thinking that they could stop him with their pathetic power and prepares to strike Kota.

Suddenly, Izuku jumps at Muscular using One For All Full Cowl, telling him that he is the one at fault. Izuku analyzes that the villain's speed surpasses his own and his only chance of victory is to close their speed gaps. Izuku punches the villain with his broken arm, trapping it between the villain's muscle fibers. The villain mocks Izuku for thinking that his plan to put them in a position where speed does not matter will work since his inferior strength will not save him. However, Izuku tells the villain that his job as a hero is to put his life on the line for the sake of others. With no other choice, Izuku decides to unleash his Quirk's full power: One For All 100%.

Izuku uses One For All 100% against Muscular, which blasts the villain with great force into the cliffside and also partially destroys the cliff due to the massive impact. Kota is sent flying away, but Izuku manages to grab Kota’s shirt with his mouth and drags him back onto the cliff. After apologizing, Izuku decides that they should quickly escape while the villain is incapacitated. However, the villain is revealed to have used his Muscle Augmentation to reduce the impact of Izuku’s One For All 100%, though Izuku’s attack did injure the villain. Muscular compliments Izuku while Izuku is shocked that his full power did nothing. Under stress and unable to think of a plan, Izuku tries talking his way out of this fight by asking the villain about the League of Villains’s goal. Muscular doesn't care about Izuku's question since he joined the League of Villains just to have fun. Muscular replaced his artificial eye with another one to show that he is being serious.

Izuku orders Kota to grab on to him; Izuku uses One For All Full Cowl to jump and run away from the villain. Izuku manages to avoid the villain’s first attack, but barely avoids the villain’s second strike which sends Izuku and Kota tumbling down the cliff again. The heavily injured Izuku believes going to the facility is the best option but realizes that his speed won't allow him to outrun Muscular. Izuku quickly forgets about the plan considering the grave circumstances he is in and decides that he has no choice but to defeat the villain. Izuku tells Kota to run back to the facility as fast as he can the second he clashes with the villain. Kota doubts Izuku’s strategy due to his attacks proving to be futile. Izuku uses 100% Detroit Smash against Muscular which keeps him at bay; Izuku orders Kota to escape while he still can but the villain considers Izuku’s struggles to be in vain. The villain begins overpowering Izuku’s attack and begins pushing him into the ground while demanding blood and death. Izuku is barely able to hold back the villain’s strength.

Izuku is shoved into the ground by the villain. Suddenly, Kota blasts water at the villain, demanding that he stop. However, the villain says that he will kill Kota after he is done with Izuku. Furious, Izuku refuses to let the villain kill Kota and begins pushing back the villain, eventually pushing the villain off him. Izuku uses 1,000,000% Delaware Detroit Smash against the villain, a powerful attack with incredible force that smashes the villain into the cliff. The villain’s artificial eye pops out and the villain becomes incapacitated due to the great force of Izuku’s attack. Kota is in disbelief that Izuku would go so far to protect him even though he doesn’t know anything about him, as he remembers what Mandalay told him; that one day he will understand why his parents sacrificed themselves to protect the lives of others when he goes through a similar situation. He will also understand that Heroes risk their lives to save people so that one day someone can call them “My Hero”. Kota cries in disbelief while Izuku roars with triumph.

Izuku notes that his job is not finished and must inform Shota and the Pussycats about the enemy’s strength. Izuku tells Kota that they can leave the unconscious Muscular where he is because he will not be waking up anytime soon. Izuku tells Kota that the wildfires will be a detriment and that they need his Quirk. Izuku asks Kota to use his Quirk to save them just as he saved Kota. Izuku has Kota jump onto his back and starts running back to the facility. Running in the forest, Izuku encounters Shota and asks him to take care of Kota. While going back to the facility, Kota wonders if Izuku will be alright, crying that he did not get a chance to apologize. Shota tells Kota that Izuku will be alright and advises him to thank Izuku the next time he sees him.

At the facility, Shota asks Vlad King to look after Kota. The Vanguard Action Squad's attack ends after Katsuki is captured.

Two days later, the doctor at the hospital Izuku is currently in hands him a letter from Kota. The letter thanks Izuku for saving him and hopes that Izuku gets well soon so that he can thank him in person.
