Name : Katsuki Bakugo (Japanese: 爆豪 勝己, Hepburn: Bakugō Katsuki), also known by his nickname Kacchan (used by Izuku Midoriya in the series) (かっちゃん, Kacchan) and his hero name Great Explosion Murder God Dynamight (大・爆・殺・神ダイナマイト, Daibaku Kisshin Dainamaito), is a superhero and one of the main protagonists of the manga series My Hero Academia, created by Kōhei Horikoshi. Katsuki's Quirk is Explosion (爆破), which allows him to make explosions from his hands by detonating the nitroglycerin-like substance he sweats; throughout the series, he learns various different ways to apply this. Overuse of the Quirk can cause pulsating pain in his arms and shoulders.
