Atomic Samurai (アトミック侍, Atomikku Samurai) is a S-Class, rank 4, superhero for the Hero Association.

Appearance
Atomic Samurai has long black hair tied back in a topknot. He has sunken cheeks, a defined jawline and a small goatee. His attire consists of a hooded cloak with an atom symbol on the back that's draped over his open coat. Beneath the coat is a typical samurai gi and the footwear is a pair of waraji sandals. He sports a pair of katanas on his left hip, and based on the length, it is likely that he wields either a daito, a ōdachi, or both. The tsuka is typical for a katana, but the unique design would be the atomic shape of the guard.

Personality
Atomic Samurai has a rather prideful personality, seen when he refused to shake Saitama's hand telling him that he only acknowledges the strong and saying that he would greet him only if he makes it to the higher ranks of S-Class. He also appears to dislike being called old.

Alien Conquerors Arc
Atomic Samurai first greets Bang, Genos, and Saitama enthusiastically as they arrive at the Hero Association meeting, although he notes that he does not know who Saitama is. Bang likewise acknowledges him and Saitama moves to shake his hand, which Atomic Samurai deftly denies, stating that he will acknowledge Saitama only when he has made it up to S-rank on his own.

During the meeting, Atomic Samurai wonders if Bang will teach Saitama and Genos martial arts, thinking that they will make decent rivals for his own disciples.

Later, after A-City and a would-be-opponent Sky King are destroyed by the newly arrived Dark Matter Thieves, Atomic Samurai's disciple Iaian enters a skirmish with Melzalgald. After Iaian loses his left arm, Atomic Samurai intervenes by attacking the alien. Realizing the heavy wound of his disciple, he vows to not allow Iaian's swordsmanship to end in this tragic way. Atomic Samurai then engages the enemies in combat alongside Bang, Metal Bat and Puri-Puri-Prisoner. During their fight against Melzalgald, Metal Bat exposes its weakness by destroying the vital marble that allows him to regenerate, thereby allowing the four S-Class heroes to successfully counterattack. However, Atomic Samurai is surprised to see Bang, who was caught off guard during his counterattack, get sent flying across the battlefield by a direct blow received from the monstrous alien.
