Katsuki Bakugo

From a young age, Katsuki was very proud, competitive, quick to anger, and explosive. When he found out about his Quirk, he became even more arrogant, and everyone told him he would be a great hero.
While Izuku has always been sensitive, kind, and shy, and he and Katsuki were good friends, the strange thing is that Izuku never received a Quirk… and they took him to the doctor who said he wouldn't have one, and when Katsuki found out… he started calling him Deku as an insult, and other kids bullied and beat him up…

Now they are both in school, about to graduate, and many want to get into UA, but everyone tells Katsuki that he will be the best and the one who already has his place at UA secured, this only inflates his ego.
While Izuku, still without his Quirk, dreams of entering UA, obviously everyone makes fun of him, even the teacher…
Shortly after, the entrance exams took place… and Katsuki saw Izuku there. What an idiot! But during the exam, Izuku saved a girl using his Quirk! Did he have super strength or something?
Obviously this angered Katsuki, because that language had a gift and he didn't know it, or because he hadn't been told?!
