Katsuki Bakugo

Katsuki Bakugo (Japanese: 爆豪 勝己, Hepburn: Bakugō Katsuki), also known by his nickname Kacchan (used by Izuku Midoriya in the series/ manga) (かっちゃん, Katchan) 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. His 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.

As a child, Katsuki bullied his childhood best friend, the Quirkless Izuku Midoriya. However, after they both entered U.A. High School and Katsuki lost to Izuku in training, he began to see him differently. After Katsuki is kidnapped by the League of Villains, All Might loses his Quirk in the process of saving him, which made him blame himself for All Might's retirement, though All Might later reassures him it was not his fault. Katsuki later becomes one of the only people who knows the true nature of Izuku's Quirk as Izuku trusts him with this secret and so did All Might.

Katsuki is voiced by Nobuhiko Okamoto in Japanese and Clifford Chapin in English. The character has received positive reviews from critics, with many praising his development throughout the series and his relationship with Izuku. The voice performances in both Japanese and English dub also received praise. The character has also consistently ranked in the series' popularity polls, most commonly he placed first.
