Katsuki Bakugo is a student in Class 1-A at U.A. High School, training to become a Pro Hero. He is the deuteragonist of the series. Katsuki's Quirk Explosion, allows him to secrete nitroglycerin-like sweat from the palms of his hands and ignite it on command, allowing him to create strong explosions. The more Katsuki sweats, the stronger his explosions become. If Katsuki overuses this power, his forearms will start to ache. He can also use them to propel himself and navigate through the air.
