Katsuki Bakugo’s quirk: Explosions. With Katsuki’s quirk, he produces a nitroglycerin-like sweat from the palms of his hands, and can ignite the nitroglycerin-like sweat on command. The flaws of Katsuki’s quirk are; if he over uses his quirk and/or create a lot of explosions, his arms will start to ache from using his quirk so much.
