Race Human Occupation Superhero Level S-Class; Rank 7 Affiliation The Heroes Association Despite not being the highest ranked hero of the Heroes Association, he is considered to be the most powerful man on Earth, and it is due to this strength that he receives praise and respect from fellow heroes. His strength is so feared that criminals and mysterious beings will surrender before having to fight him. Appearance: King has slightly long, blonde, brushed back hair along with three long scars on the left side of his face. He wears a turtleneck sweater, has sunken cheeks, a defined jawline and a squarish chin. Notably, a loud drumming sound may be heard in his proximity. The King Engine is a rumbling sound that others claim occurs when King readies for battle or when he is generally serious having an intimidating effect on his opponents.

Spoiler

In actuality, it is simply the sound of King's heartbeat which, when he is frightened, is so loud that it can be heard outside his body, but because of King's intimidating reputation people mistake it for bloodlust. King is able to appear to remain calm in threatening situations as well as put out an extremely threatening aura. Despite the intimidating personality King projects, he is actually a coward and an otaku. He has been shown to get very excited about buying a dating game. Saitama saved his life many times, but always end up getting all the credits that was supposed to be for the latter. With this misunderstanding, he came to be known as "the strongest man on earth". He got his scars from the Octopus Claw man.
