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.

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 has received positive reviews from critics, with many praising his character development throughout the series and his relationship with Izuku.

In the first draft of the series, Katsuki was a genius with a nice personality, though Horikoshi scrapped this idea because it was too boring.

[2] After the series' anime adaptation premiered, Horikoshi began writing the character with Nobuhiko Okamoto's voice in mind.

Katsuki begins the series as an intelligent student with aspirations of being the world's greatest hero, but had an arrogant, violent and crude personality.

Katsuki receives character development on par with Izuku, learning the importance of teamwork and co-operation, becoming a leader, accepting help, and how to save others in order to win.

After being kidnapped by the League of Villains, and refusing their offer to join them, Katsuki is rescued by All Might, his childhood hero.

After defeating Izuku, All Might arrives to stop the fight, reassures him that what happened was not his fault, and tells him the Origins of All For One, the injury that limited his hero work, his need for a successor, and All For One.

This rivalry becomes a quick rekindling of their childhood friendship and the pair talk more since the fight, although sometimes playfully antagonistic.

While gaining valuable lessons attending his internship with Izuku and Shoto, Katsuki's heart begins to open up more to people.

In a moment of pure urgency, Katsuki awakens a new explosive technique that propels him fast enough to push Izuku out of the way and tank the hits himself.

High School during the Dark Deku Arc, Katsuki and the rest of Class 1-A track down Izuku to bring him back to U.A.

During the final battle, Katsuki faces off against an All For One-possessed Tomura Shigaraki, who gives him a fatal blow to the chest, killing him.
