The split-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 split-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 Crabrante's chest while he was asleep in the park.



Being attacked by Crabrante

He was first seen playing with a ball at the park until Saitama came and questioned him about Crabrante. Suddenly, Crabrante appears and attacks him, but Saitama protects him.[1]
