The ball-chinned kid (アゴの割れたガキ) is the grandson of Agoni, a multi-millionaire and the founder of the Hero Association. He was saved by Saitama three years prior to the start of the series.


The ball-chinned kid is largely characterized by his enormous cleft chin. He is a young boy with short black hair. He wears a white T-shirt with orange shorts and blue sneakers.


He seems to be mischievous, drawing nipples on Crablante's chest with permanent marker while he was asleep in the park. He was also very attached to his soccer ball, because in a life and death situation where he could be easily killed he still wanted to save it.



Being attacked by Crablante

He was first seen playing with a ball at the park until Saitama came and questioned him about Crablante. Initially Saitama was going to ignore him and mind his own business because the kid is not cute (ugly). Suddenly, Crablante appears and attacks him, but Saitama rushes in to protect him despite his initial feelings about him.[1]
