Background

Before registering with the Hero Association, Saitama acted as an unknown hero purely as a hobby. He first appears in City M, where he destroys Bean Sprout with a single punch after the monster freezes his sweet potato and threatens to make him miss a sale. 1

Wu Di approaches Saitama under his own name and invites him to take the Hero Association examination. Saitama accepts enthusiastically, hoping that formal recognition might earn him a fan club or merchandise; the two exchange phone numbers and arrange to test together. 7

Appearance

Saitama is bald and is recognized by his cape-like hero attire. 1

• Completely bald head. 1
• His unassuming appearance causes other examinees to underestimate him. 10
• Genos and others commonly address him as “Teacher Saitama.” 15 163

Personality

Saitama treats hero work with unusual casualness. He is motivated by everyday concerns—including supermarket sales, groceries, and premium wagyu beef—even in the aftermath of major battles. 1 132 163

Despite his laid-back demeanor, he consistently intervenes to protect others. He defends Garou from Sweet Mask's attempted execution and later spares Garou because he is a hero and recognizes the child's belief in Garou's better nature. 99 100

He also wants his work to be acknowledged. Before joining the Association, he complains that defeating many monsters should at least have earned him a fan club. 7
