Kota Izumi

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

Appearance
Kota is a small boy who stands at a height comparable to Minoru. He wears a white, buttoned, collared shirt, dark shorts, and black boots. Kota has short, spiky black hair and wears a red hat with golden, spike-shaped horns on the front.

Personality
Kota is a normally a reserved, angry misanthrope who hates being around those who desire to become heroes. So much so, that he punched Izuku in his privates the moment they met. Kota also doesn't seem to be a fan of indecency. Shown when he stopped Minoru from peeping on the girl's hot spring by throwing him from the top of the wall.

Due to the premature deaths of both his parents, Kota has a cynical and jaded view of heroes. He believes that his parents abandoned him by choosing to work as Pro-Heroes.

Kota detests not only heroes but villains, quirks and the current superhuman society in general as well. Kota views heroes and villains killing one another with their "corny powers" as just shows of strength for popularities sake. To Kota, this conflict is what causes misery in the world.

Kota's views have slightly changed since being rescued from the villain Muscular. Izuku saved Kota from the villain, which garnered appreciation from the young boy.

History
Two years prior to the current story, Kota's parents sacrificed themselves to save civilians from a villain. Believing they died a truly heroic death, Water Hose were praised by many supporters. Kota however, was devastated by their deaths. Kota believed that his parents chose their work over him, and developed a twisted view on the world of heroes.

Kota was taken in by the Wild, Wild Pussycats, a hero team that Shino Sosaki (his last known relative) is a part of. Despite despising heroes, Kota listens to his relatives and the Pussycats because he has nowhere else to go.

Forest Training Camp Arc
Students from U.A. High arrive at the Pussycat's reserve to train for their summer break. The Pussycats introduce themselves but Kota remains silent. Pixie-Bob sends the students into the Beast's Forest and fights them using her quirk to create dirt monsters. Kota watches the start of the fighting, but Mandalay tells him they're going back to base camp. Kota thinks their training is pointless, and that the students are stupid for wanting to become heroes. He snarls and leaves with Mandalay.

Class 1-A doesn't arrive at base camp for several more hours. Izuku asks Pixie-Bob who's kid Kota is. Mandalay clears up the confusion and explains that Kota is her cousin's child. Mandalay asks Kota to introduce himself, but he remains silent. Izuku walks over and greets Kota personally. Izuku outstretches his hand, but Kota greets him with a swift punch to the groin. Tenya runs up to check on the blindsided Izuku and yells at Kota. Kota angrily replies that he refuses to hang around a bunch of wannabe heroes and storms off.

At dinner, Kota helps Mandalay with a box of vegetables. Later on, she places on the wall splitting the boy's hot springs from the girl's. Minoru tries to scale this wall in order to peep on the girls. Kota catches him at the top of the wall and tells him if he's going to be a hero, he needs to learn how to be a decent person. He pushes Minoru down the wall, garnering praise from the girls. Kota mistakingly looks back and sees the nude girls, causing him to faint and fall over the wall. Izuku catches him and brings him to Mandalay's office.

Mandalay thanks Izuku for saving him and explains Kota fainted from the fear of the fall. Izuku asks why Kota seems to hate heroes. Pixie-Bob enters the room and tells Izuku that Kota's parents were Pro-Heroes who died in the line of duty. To Kota, his parents abandoned him for their hero work.

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.
