This is a list of the canonical fictional characters appearing in the Japanese manga series One-Punch Man by ONE (story-original manga) and Yusuke Murata (readaptation).

Main characters

Saitama

Voiced by: Makoto Furukawa (Japanese); Max Mittelman (English)

• Hero name: "Caped Baldy" (ハゲマント, Hagemanto)

The protagonist of the story, Saitama is currently the most powerful known being in the entire universe, possessing limitless strength, speed and stamina, reflexes to match his speed, complete invulnerability and an indomitable will. Though his powers are limited to improvements on typical human traits (e.g., he cannot fly or project energy), his physical capabilities are so advanced that no enemy has ever managed to harm him in any way. Saitama holds back in all of his fights in an effort to entertain himself, but almost all opponents he faces are defeated with a single, nonchalant punch, typically to his dismay. As a result of his power, no opponent has ever been able to get him to draw out all of his strength in a fight, with Boros, who was capable of destroying a planet, noting that Saitama was still holding back by the end of their fight. Consequently, the upward extent of Saitama's power is still unknown.

Saitama began training to become a superhero 3 years prior to the start of the series after he defeated a crab-like monster that attempted to kill a child. His training regimen consisted of 100 push-ups, 100 sit-ups, 100 squats and a 10k run every single day, while also refusing to use the air conditioning and heat to strengthen his mental resolve. Saitama genuinely believes that this training is the source of his inconceivable physical prowess, much to the disbelief of other characters in the series who note that his methods, while obsessive, are still fundamentally basic workout routines. The gross disproportion between Saitama's training regimen and the magnitude of abilities he developed has led other characters to theorize that Saitama either possessed latent superhuman qualities that manifested through his training, or that his sheer willpower has removed his natural limitations and growth potential.

By the start of the series, Saitama faces an existential crisis of perpetual boredom due to his immeasurable strength keeping him from finding a challenge. His strength causes him to become increasingly emotionless, but he begins to discover different uses for his power upon meeting Genos and joining the Hero Association. As a hero, Saitama does not seek recognition or public acceptance. Saitama often states that his sole reason for being a hero is simply for fun, and often acts in a way that damages his reputation for the sake of saving the reputation of others. Despite his apathetic demeanour and plain appearance, his underlying charisma and sense of justice, coupled with his unfathomable power, have caused several higher ranking heroes in the association to take an interest in Saitama, with a few even making a point to befriend him.

He registered with the Hero Association and was placed into C-Class (his physical scores were off the charts, but he nearly flunked the written test for the entry exam). He eventually made the leap to A-Class Superhero after saving various cities on numerous occasions with minimal effort. He is tasked with defending Z-City against monsters under the Hero Association name Caped Baldy (ハゲマント,Hagemanto)

Saitama is a bald, ordinary looking man of average height and weight with a lean, well-built physique. He claims to have lost all of his hair suddenly and prematurely as a result of the toll taken on his body by his intense hero training. He has also claimed to have lost the ability to feel anything as a result. Three years before the story, Saitama had spiky, black hair and full brown eyes.

Saitama is usually deliberately drawn in a simpler style than all the other characters, with an elliptical shaped head and only a simple mouth and eyes. When drawn in a more serious style with more detail, Saitama is revealed to have sharp features, dangerous looking eyes, and a chiseled musculature. Even his posture undergoes a metamorphosis, with a slack posture and sloping shoulders when lax, while possessing a straightened posture and squared shoulders when serious. His costume is a plain yellow jumpsuit with a short zipper at the collar, along with a black belt with a golden buckle at the center. The costume is finished out by a red ensemble of boots, gloves, and a white or red cape.

Genos

Voiced by: Kaito Ishikawa (Japanese); Zach Aguilar (English)

Hero name: "Demon Cyborg" (鬼サイボーグ, Oni Saibōgu)

Genos (ジェノス, Jenosu) is a cyborg who decided to become Saitama's disciple after bearing witness to Saitama's easy victory over Mosquito Girl. While Saitama was adamantly against his decision, he accepted after Genos suggested paying part of his rent. Genos tells Saitama about the Hero Association when he hears Saitama's complaints about not being recognized despite his actions, and they both decide to take the official hero exam and become registered super heroes, where Genos immediately gets placed into S-class after acing both the physical and written tests. Genos is often overzealous and defensive when Saitama is not recognized by the other heroes for his feats, despite Saitama himself not really caring. Genos is a very serious character to the point of naïvety (a deliberate foil to Saitama's carefree demeanour), with his eagerness to learn from Saitama leading to him logging everything about Saitama's lifestyle. While he is one of the few heroes that is aware of Saitama's true power, he does not believe that Saitama became stronger through the mundane training regimen he did to get his powers, and as such he makes an effort to understand every facet of Saitama's life to determine what may have drawn out his strength.

Genos was at one point a normal child, but 4 years prior to the start of the story line his family was killed by a rampaging cyborg. Genos was nearly killed in the attack and his body was destroyed, so to keep him alive and equip him for revenge, a scientist took him in and modified his body to make him a cyborg with destructive capabilities. Genos' body grants him super strength, speed, stamina, a tracking HUD that can keep up with the likes of Saitama, and an arsenal of heat based weaponry, often firing balls of heat energy from his palms. Genos frequently obtains machinery from defeated cyborgs during his work as a hero to increase and upgrade his arsenal.

Hero Association

The Hero Association is a superhero organization founded by a multi-millionaire in order to fight monsters, crimes, and various threats. The Hero Association Association uses a class-system with 4 classes (from C to S) and ranks within those classes to organize every superhero accordingly. Right now, the Association counts about 547 heroes (17 S-Class, 39 A-Class, 101 B-Class and 390 C-Class).

S-Class Heroes

The S-Class has a total of 17 superheroes.

Blast

Blast (ブラスト, Burasuto) - Rank 1 is the most powerful hero in the whole Association alongside Saitama, whose whereabouts and identity are currently unknown. He looks like an average man with a superhero costume and a cape. He is said to show up on his own terms and seldom responds to requests from the Hero Association, indicating that just like Saitama, he also looks for a worthy opponent. As one official of the Association mentioned, Blast may only truly reveal himself when a "God" level threat endangers humanity. During Tatsumaki's imprisonment in a research facility, he was attacked by a monster. Blast arrived and killed the monster in an instant, but he pointed out that she could have killed the monster on her own. He then encouraged Tatsumaki to never depend on others but herself and that she should not expect anyone to come and save her. Coincidentally, he treats his job as a hobby like Saitama does.

Terrible Tornado

Voiced by: Aoi Yūki (Japanese); Marieve Herington (English)

Terrible Tornado (戦慄のタツマキ, Senritsu no Tatsumaki) - Rank 2 is an incredibly strong esper possessing unmatchable psychic powers. She is youthful in appearance (Despite being 28, Saitama often mistakes her for a child) and often acts very childish, being very condescending and selfish when interacting with others. She is prone to tantrums when people ignore her, and her sociopathic nature is revealed to stem from childhood traumas of being tested in research facilities and witnessing her sister Fubuki being bullied for also possessing telekinetic powers. As a result, she has developed an overprotective relationship with her sister and makes a point not to forge friendships.

True to her rank, she is much stronger than even her fellow S-class heroes and is able to defeat even "Dragon" level monsters with no or little effort (while some of the other S-Class heroes can't even defeat a single "Dragon" class monster without help); with her immense telekinetic powers she could uproot an entire underground base along with all of its inhabitants, send hundreds of artillery shells launched by a space ship back at the ship with ease, and even pull a meteor from space to destroy a monster.

Silver Fang

Silver Fang (シルバーファング, Shirubā Fangu) - Rank 3 is an expert martial artist, master of the "Water Stream Rock Smashing Fist" (流水岩砕拳, Ryūsui Gaisai-ken), and one of the most powerful human combatants in the world, despite his age indicating that he is the oldest hero in the whole Association.

He owns a dojo with only a single student, Charanko, after Garou, a former disciple of his, attacked the dojo and defeated every single student to the point of near death.

As a hero, Bang is wise and displays a great deal of patience when compared to others in S-class, and often scolds other heroes for being too prideful and selfish. He is one of the few heroes to recognize Saitama's true power, which he witnessed when Saitama destroyed a meteor that was going to wipe out a city.

At first believed to be the most physically powerful man on the planet and feared even by others in the S-Class, King (キング, Kingu) - Rank 7 is in actuality a completely normal human who has accidentally been credited for most of Saitama's achievements. The only two things abnormal about King are his God-level gaming skills and his exceptionally loud heartbeat when scared, which is ironically feared by his enemies and mistaken as his impressive fighting spirit: "The King Engine". He has three long scars on the left side of his face, caused during one of his first meetings with monsters (which Saitama killed) and typically wears casual habits, sometimes with some anime references on.

However, he arrives at the scene when Saitama has already killed the monster. He's one of Saitama's neighbors in his new habitation in the new Heroes Association headquarter, and came to his house together with Forte and Butterfly DX with almost hostile intent since Saitama didn't come to great him as a senior, but he ended up feeling no grudge against Saitama (he even thanks Saitama for the tea).

However, Saitama beat him unconscious almost without noticing it. Despite his sneaky nature, he takes his job quite seriously since he decided to face the Sea King in a shelter, in order to protect the civilians in there, even if he was alone with minor heroes; he was quickly defeated, but he bought enough time to let Genos enter the scene and, with his intervention, he saved many lives.

During that period he had already begun to act like a hero, calling himself "Name-less Bicycle Commuter". He at one point attempted to stop the two delinquents who attended the school and took some people's money; it was later insinuated that he was beaten up by them. Even if it's stated that he could rank up to B-Class, he decided to remain the first ranked C-Class hero because he doesn't feel ready for B-Class yet. Mumen Rider makes his first appearance when the Paradisers was causing havoc in the city streets, trying to oppose the criminal group but being beaten down in an instant.
