Background / History

Saitama became a hero “out of interest,” but his overwhelming strength left him detached from ordinary life. By the time Naruto encountered him, Saitama believed that fear, anxiety, joy, and anger were fading from him, possibly traded away for power. He still eliminated threats such as Car Man with a single casual punch, then returned to mundane concerns like buying ingredients for hot pot. 271

Naruto used illusionary power to place Saitama in a dream where the Subterraneans could injure and challenge him. The experience rekindled Saitama's fighting spirit and led to the emergence of Bald King Demon, though he awoke to learn that the satisfying battle had only been a dream. 272 274 275

Genos later sought Saitama out as a master. Although Saitama repeatedly rejected the title of “Teacher,” he eventually accepted Genos as a disciple and became involved in the conflict with the House of Evolution. His simple three-year training regimen bewildered Genos and Carnage Kabuto alike. 279 284

After defeating Sonic and realizing that his hero work had earned him almost no public recognition, Saitama registered with the Hero Association. Despite a perfect physical score, his poor written score placed him at the bottom of C-Class. 289 290 291

Appearance

Saitama is a bald man with an unremarkable, often listless expression that conceals exceptional physical power. His shiny head is a frequent source of irritation and misunderstanding. 271 279

• Shiny bald head; Saitama considers his baldness a consequence of training. 284
• Often has “dead fish eyes” and an expressionless face. 271
• Wears a hero costume with a cape and red gloves. 291 292
• His upper pajamas were destroyed during the Subterranean battle. 274

Personality

Saitama is casual, easily bored, and initially treats heroism as a hobby rather than a profession. He has little interest in lectures, rankings, or formalities, but becomes intensely frustrated when his lack of recognition threatens his image or hero status. 271 289 291 293

Despite his detached demeanor, Saitama wants a worthy opponent and responds strongly to the thrill of a difficult fight. The Subterranean dream briefly restores his vitality, while Naruto's later challenge allows him to rediscover excitement in battle. 275 394

He is particularly sensitive about being bald and intensely hates mosquitoes. Food, supermarket sales, manga, and video games can also command his full attention. 275 279 291 392

• Genos — Saitama's disciple and roommate. Saitama is uncomfortable being treated as a master but accepts Genos's devotion, spars with him, and lets him pay rent. 279 291 293
