I may not have a quirk, but I have 5 cans of redbull, 3 brown belts and spite and I have a distinct feeling that's more than enough.
ᗰIᑕᕼI ᗩᗷE
Gender: Doesn't care what he's called, officially male
Quirk: None
Age: 15
Orientation: Bisexual
Appearance: Short green hair that has one long and curly strand he likes to twirl, pale blue eyes he uses to glare at people, and two small horns that curl at the top. The horns have nothing to do with any quirks and is just something he was born with.
Normal outfit: Whatever he found in the closet (he doesn't look very fashionable because of it)
Hero outfit: An enhanced version of usual judo robes, with gauntlets on his arms and feet to help him be stronger.
Personality: Michi's had it with the world and its crap. Telling him he can't be a hero because he doesn't have a quirk, telling him he's a good for nothing, telling him he'll never make it far. Hah, we'll see about that! Michi is fuelled by pure spite and refuses to let anyone tell him what he can't do, much less mock him for it. He'll take any challenge, just to show off or put someone in their place. No matter how stupid his quest looks, he won't stop until he has earned what he fought for. When cooled down however, he is a pretty chill dude who doesn't mind helping out a friend and laughs at stupid jokes.
Powers: Michi doesn't have any quirk, but he has trained from a young age to be just as capable. He is athletic, pretty fast and his strength is not too shabby either. He mostly shines in close combat though, with his fast reflexes and skill making up for his lack of superhuman strength and power. He is trained in three fighting sports and likes to try to copy wrestling moves. However, because he has no quirk, he is often forced to read into his opponent and try to outsmart them with any advantage he can get rather than fighting them head on. Which works...until he is directly challenged.
Backstory: Michi was born as part of the 20% of people born without quirks. This made him a easy target for bullies. One day, a girl helped him find off his bullies with nothing more than simple hand-to-hand combat tricks. Not long after that, he was begging his parents for fighting lessons. With determination and a bit of a talent for fighting sports, he quickly grew to have three brown belts. Fuelled with both spite and ambition, Michi set out to earn his black belts and become the first quirkless superhero in Japan.
