Explosion (爆ばく破は Bakuha?): 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. Katsuki has a strong grasp on the applications of his Quirk, not only can Katsuki use the explosions for attacking, he can also use them to propel himself and navigate through the air.
