The Ball-Chinned Kid (アゴの割れたガキ) is the grandson of Agoni, the multimillionaire founder of the Hero Association. He was saved by Saitama from Crablante three years prior to the start of the series.

Appearance
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.

Personality
The Ball-Chinned Kid is mischievous, drawing nipples on Crablante with permanent marker while the monster was asleep in the park. He is also mindless, worrying about his ball in a perilous situation.

History
Saitama ran into the Ball-Chinned Kid playing soccer in a park. After questioning the boy about Crablante and knowing that the latter was trying to find and kill him, Saitama began to walk away, reasoning that the situation was none of his business. Suddenly, Crablante appeared and attempted to kill the boy but he was saved by Saitama who returned and fought the crab humanoid monster.
