Saitama (Character) - Comic Vine

Saitama is the main protagonist in One Punch Man, as well as the most powerful hero alive. As the title suggests, he is able to defeat any monster he comes up against in one punch. Due to just this, he faces a self-imposed existential crisis, as he is too overwhelmingly powerful to gain any thrills from his battles. He registers in the Hero Association along with his sidekick Genos.
