Ikkaku

Ikkaku is a character from My Hero Academia: Team-Up Missions.

Appearance
Ikkaku is a boy with long spiky hair combed down, covering his right eye almost constantly. Due to his Quirk, a long horn grows on his head. His style of clothing consists of a short-sleeved shirt on top of a long-sleeved, dark one, two small fanny packs, dark shorts, and a spotted neckerchief.

Personality
Ikkaku is a jovial and energetic boy, with a prankster personality who loves to do all kinds of mischief to get attention, which causes him to be frequently scolded by his teacher. He also tries to constantly show others how awesome he is, which often gets him into trouble. Ikkaku has a great admiration for heroes and wants to become one as well, although his image of heroes is too idealized and fanciful, seeing them as incredible people with awesome powers, which makes him look down on those with plain Quirks, like Mashirao Ojiro.

However, this attitude is due to Ikkau having an inferiority complex over his own Quirk. Deep down, he is envious of the flashy Quirks that his classmates have, and considered his own as lame and not very useful in becoming a hero. Mashirao realises that Ikkaku seeks attention and approval to compensate for having what he sees as an unimpressive Quirk. His way of thinking and the opinion of his own Quirk changes however after seeing Mashirao defeat a villain, showing him that having a modest Quirk is not an impediment to becoming a proper hero.

Synopsis
Mashirao Ojiro and Toru Hagakure arrive at Oku Island, where they are sent on a Team-Up Mission to give lecture to some young kids at a private hero school, Terakoya. Once they arrive, the hero students spot a rope tied near the entrance. Mashirao inspects it only to get caught in a net trap, Toru laughs at him while Ikkaku reveals himself to be the one who set the trap, introducing himself as a future hero. Ikkaku's teacher immediately runs in and scolds the boy for his prank while welcoming the two hero students and apologizing for Ikkaku's behavior. Toru asks Ikkaku if he can teach her to make a trap like that, and the boy says that he might. After hearing from the teacher that the two came from U.A. High School, Ikkaku believes that that means they are "awesome".

Inside, Mashirao introduces himself as the hero Tailman. Ikkaku eagerly asks what his Quirk is, only for Mashirao to point out that his Quirk is his Tail. The students explain that they've heard all sorts of rumors about U.A. High, including that the training there is like none other, and that there are secret labs with genetic experiments that mix Quirk Factors together, though Mashirao dismisses these as just rumors. When asked what it takes to be hero, Mashirao goes on to explain that it takes training, dedication and patience though the kids quickly find him boring and Ikkaku calls him super plain, words that strike Mashirao. Ikkaku goes on to explain his perception of heroes: how they're awesome people with powerful Ultimate Moves and Quirks who do awesome things.

Toru shines light from her invisible body to get the kids attention and then introduces herself as Invisible Girl. Mashirao soon finds that the kids are more interested in her. Ikkaku then tells her about Oku Island's rumor that there's a treasure hidden in some ancient ruins, and that whoever finds it will gain tons of respect from everyone. Ikkaku says that once he's a hero, he'll form a hero team and invites Toru to join them. Toru considers it, but says that Mashirao has to be on it as well, though Ikkaku turns him down and says he's too plain.

Once the school session ends and the kids go home, Ikkaku hops on the ends of a fence until his horn senses something. He then jumps, saying that every hero needs a cool jumping pose, though he ends up crashing down deeper into the ground. It is here where Ikkaku finds the entrance to the ancient ruins, where he's amazed that the rumor was true. Two kids then go back to the school, saying that Ikkaku fell into the ruins, that they can't pick up his phone and that he didn't make it home either. Mashirao and Toru set out to search for the boy.

At the ruins, Mashirao and Toru search and call out for Ikkaku. The ruins then triggers a bunch of traps which Mashirao is forced to avoid (they don't detect Toru because of her Invisibility). As Mashirao perseveres through the traps however, he chooses to turn back. Ikkaku is revealed to be near the entrance, worrying that he can't proceed any further with his Horn Quirk. Mashirao finds him, but Ikkaku turns away saying that he didn't ask to be saved. Mashirao realises that Ikkaku can't show off with his Quirk so he tried to find attention some other way, causing Ikkaku to reveal that everyone at his school has powerful and cool Quirks, whereas his is just a horn that can detect certain things. Their talk is interrupted by the floor turning to rubble, Mashirao and Toru are confronted with the man they met on the boat to Oku Island, who turns out to be a graverobber in search of the treasure.

Mashirao and Toru run to stop the graverobber, whose Quirk allows him to crumble any stone he touches. Toru uses Warp Refraction to blindside the treasure hunter and give Mashirao an opening. The two engage in combat and while Mashirao is mocked for having nothing but a "cruddy tail", he ends up defeating the man through sheer strength as Ikkaku looks on in amazement.

Back at the school, Ikkaku boasts that he found the ancient ruins, though he's still told off by his teacher for having to be saved and still wanting to show off. Ikkaku admits that he does, but then says that he now knows that being a hero is about honing your natural talents. Toru states that Mashirao doesn't let his simple Quirk get in the way of his dream and calls him plain awesome, though Mashirao laments that he's still plain. Later on, Ikkaku meets up again with Mashirao who is flustered from Toru "kissing" his cheek (though Toru admits that she just tapped it with her finger). Ikkaku and Toru both congratulate Mashirao for his success and he thanks them.
