Katsuki Bakugo, also known as Kacchan by his childhood friends, and his hero name Great Explosion Murder God Dynamight is a student in Class 1-A at U.A. High School, training to become a Pro Hero. Explosion-Katsuki's Quirk 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.
