Saitama

Saitama is the overwhelmingly powerful hero and protagonist of One-Punch Man. He joins the Hero Association after becoming strong enough to defeat nearly every enemy with a single punch in One Punch Man.

Saitama's role in ONE-PUNCH MAN

Saitama is calm, bored, practical, and concerned with ordinary expenses more often than fame. His training somehow grants immeasurable strength, speed, durability, reflexes, and endurance without an established upper limit.

Saitama's relationships and major turning points

Genos becomes his disciple and closest companion, while heroes such as King and Bang gradually form his social circle. Saitama's central conflict is not survival but finding meaning, recognition, and genuine challenge.
