Unfortunately for him, One Punch Man's idea of a good time is a good fight, and no one seems able to provide him with one. He's a hero with ennui and a sense of humor.
So this bald warrior isn't really Aang from Avatar: The Last Airbender, but I like to think he could be Aang in his twenties. It's an outrageous, funny comic book. I look forward to reading the others in the series.
