King is the S-Class rank 7 superhero for the Heroes Association.
Considered the “strongest man in the world” after defeating a demon class villain effortlessly. Seems he prefers not to fight in actual combat as his name alone is enough to scare away just about any villain.
King is a normal, powerless human who just happened to be a passerby when some heroes defeat an enemy and he’s given the credit for it. One of those instances was when Saitama defeated Vaccine Man.
He claims that he’s merely a 29-year old, unemployed, useless otaku living by himself. King loves to play video games including dating simulations.
