Hero Association

The Hero Association is a public organization which gathers, coordinates, and supports individuals who possess special fighting abilities that willing to fight monsters, termed Heroes. Although founded out of good intentions, it is plagued by the power struggle between Heroes and corruption. In the face of a rise in monster activity, the association is becoming less and less able to combat the threats.

    open/close all folders 

  • Beef Gate: The #1 hero of a given class is this for every other hero within that class. In order to move up the ranks, a hero has to perform better than the number 1 of their class.
  • Fantastic Rank System: Heroes are divided into classes: From lowest to highest, they are the C-Class, B-Class, A-Class, and S-Class. Furthermore, heroes also hold a numerical rank within their respective class. Their placement in these classes reflect their strength and performances. S-Class was created after the other three as its own class, in order to assemble all of the freakishly strong heroes in one class.
  • Great Big Book of Everything: In a case of Idiot Ball, the association has published a guidebook detailing where the heroes operate and what their powers and secret techniques are. It's a miracle only Garou thought of looking that up.
  • Heroes "R" Us: The heroic organization type. However, most of the heroes don't work together at all.
  • Heroism Won't Pay the Bills: Inverted. They pay the heroes at the end of each month based on their rank, with C-Class heroes receiving the lowest pay. Their ranking is based on points earned for heroic deeds, which only the assessment board knows the criteria for. Because the Hero Association is a non-profit organization that receives their money through donations from the public, on top of having the duty to be devoted to justice and compassion, the heroes cannot complain about their pay as it would make themselves look bad.
  • Hufflepuff House: While pretty much all the S-Class heroes are given distinctive characterization and scenes, the other ranks have just one member who receives prominent characterization and development, with the rest being relegated to backgrounds and battle fodder.
  • Incompetence, Inc.:
    • What the association boils down to in later chapters. In fact, the whole organization ends up getting this reputation in the arcs after the Monster Association due in part to how the business as a whole has done nothing but screw up royally time after time. The public is particularly upset about the destruction of the Association's new HQ, the perceived faults and failings that are blamed on Metal Knight, Tornado's constant rabble rousing causing tons of property damage, and heroes as a whole doing nothing but causing one ruckus after another while on their payroll.
    • The association is in general plagued by the fact that the heroes in question are more often than not disinterested in fighting monsters. For instance, Blizzard has transformed the B-Class rank into a gang war between different factions of heroes. Also, the S-Class heroes are sometimes unwilling to fight a given monster.
    • The association is at least quick to notice and respond whenever a monster is in town. However, there are less than 600 heroes to manage an entire continent, with more than half of them only able to beat up simple thugs. The Hero Association is aware it is undermanned and is actively looking for potential allies.
    • The latest example in the ONE webcomic is when Child Emperor sends in a document laying out a well organized and thought out plan to make better use of the C to A Class heroes to cover weaknesses in the Hero system. Nobody even bothered to open it. This leads to Child Emperor and multiple other S Class Heroes to abandon the Association.
    • Child Emperor and Drive Knight point out that one of the S-Class heroes seems to be a traitor. Child Emperor suspected Drive Knight at one point while Drive Knight consistently suspects Metal Knight, Child Emperor's mentor. Drive Knight then points out to Executive Sekingar that if the traitor is Metal Knight, then it's stupid that all of their HQ defenses are run by him with no oversight. On top of this, while it may be nothing, no one suspects Blast who mysteriously retired and has disappeared. Even if Blast isn't a traitor, the fact that no one knows where their top heroes are at any given time is a major oversight.
    • Many of the executives and heroes are glory hounds only in it for fame, glory, and money. Some of the top executives are stupid, lazy, unfocused, slimy, and petty asshats. Corruption is also a problem with some members out to waste resources embarrassing law enforcement or taking girls out on dates. They also rush operations to appease investors or outright ignore problems which bites them in the ass. The latter ended with Garou taking out a huge portion of their heroes in the Hero Hunter Arc. The former ended up with the majority of the top level survivors being crushed by Garou (again) and other monsters after the heroes wore themselves out fighting opponents that they had no Intel on in the Monster Association arc.
  • Inept Aptitude Test: The entrance exam seemingly works for ordinary heroes, but fails at selecting truly strong heroes. Saitama was thrown into C-Class for failing the written exam, while his physical performance was off the charts. In fact, several of the current S-Class heroes started off in C-Class or B-Class until the association finally noticed their abilities.
  • Mega-Corp: As of the main story, this is what the HA has turned into. It started out as a philanthropic pursuit by an Eccentric Millionaire who was moved by the kind actions of a passing citizen, Saitama, but subsequently declined into yet another sham company run by lackadaisical, incompetent, conniving and/or outright JerkAss collective interests, with the well-meaning members finding themselves out-voiced or too low-ranked to do much to counter said interests. Plus, many of their heroes are, by extension, a gang of egotistical backbiting thugs and psychos who're either fighting over popularity points or causing more damage than the monsters and villains they fight. That coupled with their new HQ taking in the rich over the masses, and many of their more powerful heroes being involved in scandalous situations, has resulted in people questioning the Association as a whole, especially after events which leveled the new fortress guaranteed to outlast anything. Even its own staff are calling it a disaster with some deserting one-by-one.
  • The Nicknamer: One of their duties is giving "Hero names" to those who have achieved a high-enough rank and/or popularity, or simply making a Hero's preferred name official. While they sometimes give pretty cool names (Silverfang, Demon Cyborg, Tornado of Terror), others border on being too simplistic (Metal Bat, Eyelashes, Zombieman) and others are really quite unflattering (Pig God, Caped Baldy).
  • No Such Thing as H.R.: The Hero Association completely ignores personal feuds between heroes and the fact that new heroes are frequently rookie-crushed by stronger heroes.
  • Nothing Is the Same Anymore: In the aftermath of the battle with the Monsters Association and the subsequent battle against Garou, several heroes have gone into seclusion, or left the organization altogether — having either lost faith in themselves or in relying on the other heroes. The Hero Association itself has come to view Metal Knight and Tornado in particular, two heroes previously held in high esteem, as unreliable and/or loose cannons. Also, the public's faith in the Hero Association is ebbing away, with their focus on the publicity that the heroes bring to use their budget, and on creating a series of high-rise apartments for the wealthy using their heroes as bodyguards, which is the opposite of the original intent of the organisation.
  • Punch-Clock Hero: While there certainly are many altruistic members who want to save people and do good, as a whole, the heroes working for the Hero Association are doing it as a job. Some of the members have particular motives or side-objectives, like Metal Knight testing new weapons and Tornado wanting to find Blast.
  • Slave to PR: Because it is funded by donations, the Hero Association has "looking good" among their priorities, to the detriment of efficiency.
  • Super Registration Act: They take in and sponsor superheroes, test them on their capability as a hero, and assign them ranks and classes based on their abilities. Unlike most cases, operating as an unregistered hero isn't technically illegal, but the general public thinks of them as "weirdos" in costumes. (Saitama only signed up because he wasn't getting any recognition for his deeds.)
  • The Worf Effect: If a hero is below S-rank, their role in the story is to showcase the power of the villain de jour by getting the snot beaten out of them. The only major exceptions are Amai Mask, Blizzard, and Saitama.

S-Class Heroes

Beyond the A-Class of the Hero Association is a group of heroes whose power far surpasses that of the ordinary human: S-Class. S-Class Heroes are the highest-ranked and most powerful individuals in the Hero Association, and are so strong they typically can deal with Demon or Dragon-level threats by themselves, and are capable of protecting entire cities. There are 17 heroes who have been bestowed with the rank of S-Class. See their page for info.

A-Class Heroes

They are the second highest rank in the Hero Association. There are 38 heroes in this class.
  • Overshadowed by Awesome: They are genuinely competent and powerful heroes but are overshadowed by the S-class and the Demon Threats (or higher).
  • Worf Effect: Despite them being the second most powerful rank, they are usually seen getting beaten by threats more powerful than them whenever they make an appearance. For instance, an A-Class hero will defeat a bunch of giant monsters only to be clobbered by the toughest of them (Which are almost always Demon threat or higher). This means: "Send in the S-Class."

    1. Amai Mask 

Amai Mask

Voiced by: Mamoru Miyano (Japanese), Ben Lepley (English), Jaime Alberto Carrillo (Latin American Spanish)

Debut: Chapter 28 (Webcomic), A New Wind Blows (Manga), Episode 5 (Anime)

The number 1 A-Class Hero, but also an idol, actor, singer, and general entertainer. Amai Mask is a recurring sight on television and is mostly seen promoting himself. However, he is still insanely strong, harbors a hatred for Monsters, and disdains incompetent Heroes. He eventually tells Saitama is real name: Beauto.

  • 100% Heroism Rating: Amai Mask is the most popular hero in-universe... among the public at least. He was rated as the most popular hero for 28 consecutive weeks, and people love him so much that they overlook his dark tendencies. Amongst the Association, however, he's treated with far more disdain, and the S-Class heroes in particular either ignore him or just plainly hate his guts.
  • The Ace: Amai Mask is very handsome, strong, and charismatic. He is a singer, model, and a TV star. He is also at the top of the A-Class, wields some influence over the Hero Association's top management, and rivals some S-Class heroes in terms of combat ability.
  • Almighty Janitor: Downplayed as he is on the second highest rank of Heroes, but his powers are actually on par with at least mid S-Class Heroes.
  • Anti-Hero: He's the kind of hero who is all too willing to dirty his hands to execute those who he perceives as "evil", all for the sake of his rigid definition of "justice." Genos says Amai Mask is basically how he could've turned out if Saitama didn't enter his life.
  • An Arm and a Leg: Evil Natural Water cuts his left arm off. Amai Mask just reattaches it.
  • Be Yourself: Saitama gives this advice to Amai Mask. Saitama believes that keeping appearances is no different from being a puppet. Ultimately, how one views and accepts himself is more important and an ideal hero would never concern himself with appearances.
  • Beauty Equals Goodness: He certainly believes this. Subverted when he shows his true colors in battle. Garou calls him a horrid Narcissist. This is completely changed to Power Is Sexy. His backstory gives a full explanation of why he believes this, and it is Played for Drama.
  • Beauty Is Bad: Kinda drives the point home given his hardline sense of right and wrong regarding villains, monsters, and people who defend them. Hell, he physically distorts when enraged or in battle to showcase this point. Amai Mask even reveals that he's secretly a monster after becoming beautiful and that he was a formerly ugly heroic man.
  • Becoming the Mask: His philosophy. Amai Mask is of the opinion that people care only about appearances, thus it is important to project the right persona.
  • Beneath the Mask: Under his lavish hero lifestyle, he's almost certainly hiding a few nasty secrets. Which sort of fits his hero name, really.
  • Berserk Button: Anything that tarnishes the image of a hero in the eyes of the public. Ugly things also push his buttons so much that in his fight with Fuhrer Ugly he flew off in a rage after looking at his face.
  • Boring, but Practical: Unlike other heroes, Amai Mask does not use special techniques or even names his attacks, he just uses ruthless powerful strikes with his sheer strength to finish off his opponent.
  • Break the Haughty: Garou effortlessly defeats him, caving in half of his face right into his skull and knocking quite a few teeth out.
  • Bishōnen: He's got "handsome" in his hero name and is good looking enough to be a model/TV celebrity.
  • Broken Ace: Genos notes immediately that Amai Mask is similar to himself... except that Amai Mask has absolutely no compassion or empathy for the monsters. Not even the ones that have surrendered. Genos feels that he would've ended up the same way had he not met Saitama.
  • Bullying a Dragon: In Chapter 93, he tries to muscle in on the planning phase for the assault on the Monster Association and not only demands to be brought along, but to be placed in command of said S-Class heroes. While most of them just ignore him (or try to placate him in the case of Child Emperor), Tornado, Zombieman, and particularly Flashy Flash get incensed at his rudeness and refusal to take no for an answer, with Flashy Flash outright threatening to fight him in the meeting room.
  • Declining Promotion: While he has the skills and powers to be in S-Class, he intentionally stays in A-Class to ensure that heroes who are "weak, good-for-nothing 'garbage'" do not advance into the S-Class and make the Hero Association look bad.
  • Department of Redundancy Department: His name is Handsomely Masked Amai Mask. Speaks for itself.
  • Death Seeker: Implied. He doesn't seem to particularly care if he dies, or if he succumbs fully to the monsterfication and be eliminated, as long as he is able leave behind an "ideal hero" as a result. He believes that he'd be unable to continue his hero duties or resume his life once the truth is revealed and thus he does not see much point in living. Emphasized even further when he's pleased that Saitama returned when he has finally shown his true form, and encourages Saitama to kill him so he'd be famous overnight.
    Amai Mask: Phew... This is a great chance. If you kill me right now, you'll become famous overnight. It would be my honor to witness the birth of the "ideal hero"... Huhu.
    Saitama: Ha... You're still going on about that? You really are persistent.
    Amai Mask: Take a good look, it's too late for me. Please.
  • Don't You Dare Pity Me!: In the manga, after Tatsumaki rescues him along with most of the other Heroes battling the Monster Association, he becomes enraged at the looks of concern the other Heroes give him while he’s still recovering from his encounter with Furher Ugly. It’s to the point where he actually considers murdering them to maintain his image and reputation, but a flashback of Blast snaps him out of it.
  • Early-Bird Cameo: Appears in the anime in Episode 5 to welcome Genos to the Hero Association.
  • Establishing Character Moment: Although he appears earlier, the first time we see him actually doing his job as a hero counts as this. He gets a mission to capture an escaped unfrozen caveman, and return him alive. He butchers the escapee on sight instead. And the people cheer him on.
  • The Fighting Narcissist: Called such by Garou, who points out the flaws of his Beauty Equals Goodness mindset.
  • The Friend Nobody Likes: For the Hero Association's heroes, especially the S-Class. Practically every time he interacts with other heroes, his rude and abrasive behavior ends up pissing somebody off. Tornado flat out tells him that he wasn't included in the strategy meeting before the Monster Association raid because everyone hates him.
  • Get A Hold Of Yourself Man: Does this to himself after Iaian triggers a flashback to Blast. He'd been considering murdering the other heroes for seemingly threatening his image of an idol and a hero. He then smashes his head into the ground to regain some self control.
  • Good Is Not Nice: He's a hero, but apart from his celebrity persona, he's not a very pleasant person and is downright merciless.
  • He Who Fights Monsters:
    • His face when he confronts the Monster Association warps and spasms in a nasty way, making him look down right freakishly terrifying, like he just took off the human mask he wore to let through the disfiguring anger and hatred for monsters he has inside.
    • It happens again at the end of the Garou fight. Even when Garou has seemingly calmed down, Amai Mask is absolutely adamant Garou should die for being a monster, all the while making the scariest, most horrific face possible. He even uses it to scare the kid bystander (though he does tone it down a little bit for him), especially when the kid points out that Garou, y'know, didn't even kill anyone.
    • It turns out this is because he is already a monster, and was turning into one even before he became a hero. His strong obsession with justice and his hate for monsters are some of the only things keeping him on humanity's side.
  • Heroic Willpower:
    • It's an ability he actually invokes — his arm gets sliced clean off... and he simply re-attaches his arm again and the arm still works.
    • As it turns out, his character invokes this on a deeper level - he's actually a monster who manages to stay on the side of humanity purely through his willpower, even though (like other monsters shown in the series) his transformation constantly pushes him towards a fanatical obsession with his focus.
  • Hidden Depths:
    • As self absorbed as he may appear, Amai Mask is one of the rare people who is actually respectful towards Saitama. He deems Saitama to be an extremely worthy hero, and plans to replace S-Class heroes with him. Amai Mask does have a strong sense of justice (albeit warped by his need to keep a perfect appearance).
    • Amai Mask explains that he was born with an ugly face and initially believed that it was important to adhere to morality. No matter how many good deeds he did, people never took notice of him, prompting him to wear a mask and destroy all records of his past within the Hero Association. Over the months, the schism in his personality triggered the monsterification process within him, granting him a muscular body and a handsome face. That was when people began to notice him and listen to what he had to say. Amai believes that killing monsters without remorse is what slows down his monsterification. He also came to believe that people care only about appearances. Nevertheless, he intends to groom Saitama into a suitable hero, who would protect the masses before Amai Mask becomes a complete monster.
  • Hunter of His Own Kind: Is a ruthless killer of monsters despite being a monster himself.
  • Hypocrite: He has no problem berating other heroes for not "living up to their responsibilities" despite frequently ignoring monster attacks to further his career as a singer/actor. Played with in that he has a justification for his behavior; he considers his career as a singer/actor to be a part of his responsibilities for the sake of the Hero Association's PR.
  • Jerkass: He's a total jerk, especially to heroes who don't meet his standards. He berates the S-Class heroes for not preventing City A's destruction, even though there was nothing they could have done to prevent it, calls Genos a disappointment after he lost to the Deep Sea King, calls Zombieman a monster because of his immortality, says that Atomic Samurai's disciples are too weak to be included in the Monster Association raid and should commit seppuku if they're taken hostage... you get the picture.
  • Knight Templar: He believes that all monsters must be killed, even if they are of no threat or if given explicit orders to capture them alive.
  • Let's Get Dangerous!: After facing a monster he can't beat, Amai Mask decides to let his true monster form out to win.
  • Merchandise-Driven: Go ahead, give him even a small amount of room to promote some of his merchandise. He'll talk about it whether or not you prompted him. He happens to be the public face of the Hero Association, and although he has pull in the organization, it's not quite known how much influence he does have. If anything, though, he has more than it appears.
  • The Needs of the Many: While explaining his ideology to Saitama, Amai Mask reveals that he follows utilitarian ethics and will unhesitatingly sacrifice a small number of people for the greater good.
  • Nice Job Breaking It, Hero!: When he faces off against Pesky Clown, he learns that the monster gets stronger with attention. But when he calls for the crowd to evacuate, he instead attracts an even bigger crowd because people want to get a glimpse of the most popular hero. And then even more people start watching through the media. This powers up Pesky Clown so much that Amai Mask is forced to transform into his true monstrous form. The arc culminates in Amai Mask going from a beloved hero to a fugitive who's lost all his human rights.
  • Nightmare Face: When he gets especially angry, his eyes become bloodshot, and veins pop across his flesh, making him look even more fearsome than the monsters he fights.
  • No Place for Me There: Amai Mask's dream is to create an ideal hero that will lead humanity to victory over the monsters. He can't be that ideal hero because he's a monster himself, and knows his time is limited before he fully gives in to his monstrous nature. When he eventually sheds his human form and is unable to turn back, he's willing and honored to sacrifice his life by allowing Saitama to kill him so Saitama can be that ideal hero.
  • The Perfectionist: Together with his Beauty Equals Goodness belief, he also advocates the idea that a hero should always be a paragon of perfection, especially when it comes to their job. To him, if you're a high-ranking hero, you have to do your damn job perfectly: not only saving lives and stopping the threat, but also making sure that nothing gets destroyed and not suffering a single injury or scratch. He chastises the S-Class heroes who stopped the alien invasion by telling them that they're failures for letting A City be destroyed, despite the fact that they stopped the invasion and only knew about the threat after they got out of the Hero Association HQ and found the city already in shambles. Amai Mask states that part of this attitude comes from his desire to see a "true" hero emerge before he fully succumbs to his monsterization.
  • Power Is Sexy: Amai Mask starts believing in the "Beauty of Overwhelming Power" after he watches Saitama utterly defeat Garou. He even berates an upcoming boy band, calling them inferior to Saitama, signifying his obsession with the hero.
  • Punch-Clock Hero:
    • He is heroic only when he is out performing hero work. The rest of the time, he considers himself to be just a model and a singer.
    • In one of his first appearances in the comic he appears as the special guest of a news anchor discussing the Deep Sea King's assault, and swiftly rebukes the man for asking him to comment as a hero on the situation — he's just there to promote a new song of his.
    • Even worse, during the Alien Invasion arc, the reason he didn't show up to defend City A is that he was filming a drama the next town over. Doesn't stop him from berating the other heroes who did show up for failing to live up to his standards, though.
  • Razor-Sharp Hand: He metes justice on evil by chopping their heads off with his bare hands.
  • Renaissance Man: He's a professional hero, a recording artist, a model, and a TV star.
  • Retcon: Due to later story developments in the webcomic firmly stabilising Amai Mask as more heroic, despite his difficult personality, the manga had its original new events concerning his actions around the Do-S fight slightly altered, in order to make Amai seem less of a total asshole verging on villain territory.
  • The Reveal: He's actually a monster, having undergone the transformation before he became famous. While he starves off the mental shift such a process causes, he notes that his time is limited before he succumbs to his inner nature permanently.
  • Shoot the Hostage: In the original version of chapter 103, he sends off Atomic Samurai's disciples while he deals with the Narinki Squad, but they don't return to help like they do in the current revision. Instead, as soon as the trio are out of sight he slaughters the entire squad, before ruthlessly dealing with Do-S herself. This was changed to make him less comically evil.
  • Smug Super: He has all the stuff needed to be one of the S-Class heroes, but purposely remains as the top A-ranker. However, he's not shy about telling other heroes that they suck, and that he's better than them in every way. He even tells Atomic Samurai (the #4 S-Class Hero) that he's stronger than him to his face, though whether that's true or just arrogance talking is up for debate. Considering that in his true monster form Amai Mask is at least Dragon-level considering the power of the monster that finally forced him to reveal it, he likely wasn't lying, or at bare minimum he could definitely give Atomic Samurai a hard time.
  • Sociopathic Hero: Shows no mercy to anybody he considers an enemy. His sociopathic tendencies are shown most prominently when he encounters a group of enthralled mercenaries. Despite realizing that they're mind-controlled (and that killing the mind-controller would free them) and being so outclassed that they were barely a threat to him, he still originally brutally rips the whole group to shreds (literally) because that was easier than incapacitating or avoiding them, before killing the surrendering monster who'd enthralled them. Note that he'd dismissed the other heroes before hand (who'd been trying to non-lethally take down the group), showing that this action was likely premeditated. This was retconned into Amai only knocking them out once he noticed Atomic Samurai's disciples were watching perhaps because it was TOO sociopathic, although even in the new version he still struggled with deciding whether or not to just kill them all for being soft on evil. Amai Mask himself states that at least a part of this attitude comes from him being a monster.
  • Take Up My Sword: To Saitama. Amai Mask reveals that he doesn't have much time left before he transforms into a monster, so he wants Saitama to inherit his role and become a symbol to unite people.
  • Too Long; Didn't Dub: The dub calls him "Amai Mask", presumably in order to fit the lip movements.
  • Weaksauce Weakness: He just can't deal with really ugly looking people. This comes back to bite him later when he encounters an ugly Mysterious Being, and his body practically freezes stiff from looking at it.
  • Workaholic: He overworks himself with his hero and idol activities.
  • You Gotta Have Blue Hair: It's quite blue.

    2. Iairon 


Voiced by: Yoshimasa Hosoya (Japanese), Xander Mobus (English), Carlos Hernández (Latin American Spanish)

Debut: Chapter 34 (Webcomic), Chapter 31 (Manga), Episode 10 (Anime)

Atomic Samurai's best disciple. A serious swordsman and dedicated hero, he follows his master everywhere.

  • An Arm and a Leg: Loses his arm during the fight against alien invaders.
  • Badass Normal: He's just a guy who, for all intents and purposes, is just really good with a sword. Those skills have taken him to the second-highest rank in A-Class. And since Amai Mask himself is already S-Class level and could rise anytime he wanted to, this technically makes him the strongest of the A-Class. He's even able to keep up with the Dragon-level Melzalgard for an extended period of time.
    • To wit. During the battle against Rhino Wrestler (who gives scores to the strength of their opponent's attacks), the highest score the other heroes could get from the monster? 30. Iairon's score? 69. In fact, Atomic Samurai states that the only reason why Iairon seemed to be struggling so much is because he stubbornly kept attacking Rhino Wrestler's horn, the strongest part of the monster's body.
  • Cool Helmet: Until it gets quickly destroyed.
  • Handicapped Badass: After he gets his arm blown off fighting Melzalgard, he's still considered the 2nd ranked A-Class Hero.
  • Horrible Judge of Character: After he and his fellow apprentices have difficulty fighting a group of mind-controlled mercenaries without hurting them, he decides to let Amai Mask handle them alone and leaves simply upon the Hero's insistence, not realizing the number one A-rank is a Sociopathic Hero who simply wanted the three of them out of the way in order to kill everyone without hindrance.
    • Averted in the redraw, where they turn back because they suspect Amai Mask might be up to something questionable.
  • Iaijitsu Practitioner: Fittingly enough.
  • Ideal Hero: In direct contrast to Amai Mask, Iairon does everything in his power to do the right thing. In many ways, Amai Mask is Iairon's opposite as they are both very beautiful men on the outside.
  • Knight in Shining Armor: His whole motif. In contrast to his Western-style plate armor, however, his sword and fighting technique are both Japanese-styled.
  • Meaningful Name: His name is based on "iai" and "aian" (iron), referring both to his swordsmanship and his armored appearance.
  • Only a Flesh Wound: Downplayed. When he loses his arm to Melzalgard, he's noticeably holding his maimed arm throughout the rest of the fight and sitting it out, but despite losing an arm he spends the rest of the fight holding himself together without screaming bloody murder and instead providing commentary.
  • Throw the Dog a Bone: For his part in helping against the invasion (where he got pretty badly maimed) he got to tag along with the S-Class Heroes and Saitama when they're given an expensive vacation at a hotel.

    3. Okama Itachi 

Okama Itachi

Debut: Chapter 50 (Webcomic), Chapter 44 (Manga)

Atomic Samurai's second best disciple. She's a crossdressing swordsman.

  • Agent Peacock: Very skilled, while dressed as a woman.
  • Distracted by the Sexy: Was hesitant to fight Devil Long Hair because of how handsome he was.
  • Meaningful Name: Her name is a combination of "Okama" (transvestite) and "Kamaitachi" (sickle weasel).
  • Razor Wind: Their specialty.
  • Wholesome Crossdresser: Dresses like a woman, and is on the side of the good guys. It helps that she's actually not bad-looking, and she wears a decent, tasteful outfit.

    4. Bushidrill 


Debut: Chapter 50 (Webcomic), Chapter 44 (Manga)

Atomic Samurai's third best disciple. Although he looks like a typical ronin, he fights with a giant drill in lieu of swords.

    5. Heavy Tank Loincloth 

Heavy Tank Loincloth

Voiced by: Koichi Soma (Japanese), Paul St. Peter(English)

Debut: Chapter 45 (Webcomic), Chapter 39 (Manga)

    6. Blue Fire 

Blue Fire

Voiced by: Shintaro Asanuma (Japanese), Kyle McCarley (English), Ricardo Bautista (Latin American Spanish)

Debut: Chapter 45 (Webcomic), Chapter 20 (Manga), Episode 6 (Anime)
A man in a dark blue Kung Fu suit with an affinity for fire.

    7. Magicman 


Voiced by: Yuya Murakami (Japanese), Robbie Daymond (English)

Debut: Chapter 45 (Webcomic), Chapter 39 (Manga)
A hero with a magician motif and a pigeon sidekick.
  • Magic Hat: It's magical enough to release dozens of birds from it as an attack.
  • Stage Magician: His motif, complete with a giant top hat with a question mark.

    8. Death Gatling 

Death Gatling

Voiced by: Kento Shiraishi (Japanese), Jarred Kjack (English)

Debut: Chapter 53 (Webcomic), Chapter 61 (Manga)

A hero with very messy hair and a cross-shaped scar across his face. He wields a gigantic gatling gun in place of his left arm.

  • All for Nothing: He spent much of the battle against the giant octopus monster observing its actions in order to formulate a plan with the other A-Class Heroes to kill it. Then Flashy Flash showed up to kill it himself and render that planning useless.
  • Anime Hair: He looks like a typical Shōnen main character with his long unkempt spiky hair.
  • Arm Cannon: Of the "replaces limb" variety.
  • Awesome by Analysis: Death Gatling is very strategic when up against monsters.
  • Bottomless Magazines: Downplayed. While he fires far more bullets than a single person could realistically carry on their person, he does have a finite supply of ammunition. A limitation that Garou happily exploits to further humiliate him.
  • Face of a Thug: Despite his scary and hardened face, he is a man of righteousness.
  • Gatling Good: His main weapon, which replaces his left arm.
  • Glory Hound: Downplayed, but it's implied that Gatling implicitly didn't alert any S-Class heroes to Garou's location because he wanted himself and the other A-Ranked heroes to get full credit for capturing him.
  • Good Is Not Soft: He may be a Hero, he may even refuse to Shoot the Hostage, but he won't hesitate to kill someone if he deems them too much of a threat. He tells Garou as much before unleashing his Death Shower on him.
  • Knife Nut: Carries a combat knife on his person as a last resort.
  • More Dakka: His ultimate attack, "Death Shower", unleashes every last bullet he has into a rain of death that annihilates everything in front of him so thoroughly it might as well be a Wave-Motion Gun. Of course, since it uses every last bullet in his arsenal, if his enemy somehow survives he's pretty much screwed.
  • Overshadowed by Awesome: And he hates it. He keeps bringing together teams of lesser heroes to show the community that they are just as good as the S-Class heroes or to show, at the very least, that even lower ranked heroes can protect people. His teams are almost always outdone or outright beaten. He claims that he doesn't care about rankings, but his speech to Garou just shows how insecure he is about being outdone at every turn.
  • Pride Before a Fall: As Garou points out, had Gatling actually called in a S-Class hero to back him and his team up, they likely would've actually been able to apprehend him.
  • "X" Marks the Hero: Has a large X-shaped scar on his face, and he is a member of the Hero Association.

    9. Tank-Top Vegetarian 

Tank-Top Vegetarian

Debut: Chapter 50 (Webcomic), Big Construction (Manga)
A member of the Tank Topper Army.

    10. Stinger 


Voiced by: Tomokazu Seki (Japanese), Chris Hackney (English), Miguel Ángel Leal (Latin American Spanish)

Debut: Chapter 24 (Webcomic), Chapter 23 (Manga), Episode 8 (Anime)

Stinger is a popular fighter. He wears a tight black suit made of bandages and wields a spear called Bamboo Shoot.

  • Adaptation Expansion: He appears much more in the manga and anime than in the webcomic. For example, he never fought Garou in the webcomic.
  • Anime Hair: Unkempt spiky hair, so much that he looks like Hiruma.
  • Badass Normal: He has no special powers, just great athletic ability and that spear of his. While he does take a lot of damage in the process, he single-handedly took out most of the Sea King's underlings on his own. Each of them was, individually, ranked a Tiger level disaster. The main reason he took any damage? Because he was worried that his ultimate attack would hurt the innocent bystanders cheering him on. Given that it one-shot four opponents in one go, he was probably right.
  • Blade on a Stick: His weapon is a pole with a spearhead-like bamboo shoot on the end.
  • Death from Above: Is able to rip off a cat monsters limb from above this way.
  • Expy: His outfit and fighting style make him resemble Lancer from Fate/stay night.
  • Know When to Fold 'Em: The moment he sees the cat monster they were fighting was just a larger monster's spawn, he tells Lightning Genji they should retreat.
  • Reused Character Design: Looks like a black haired Hiruma from Eyeshield21.
  • Small Name, Big Ego: While he is more well than most examples, he is a wee bit on the egotistical side. During the Seafolk invasion, which was level Tiger, he thinks he fended off level God opponents, which are threats that can destroy the human race.

    11. Twin Tail 

Twin Tail

Debut: Chapter 93 (Manga)
A twin tailed haired, clown themed hero. She is among the Heroes sent to fight the Monster Association.
  • Blind Weaponmaster: Whether or not she's actually blind, she can apparently handle juggling weapons while in battle with a blindfold on.
  • Disability Superpower: Wears a blindfold, suggesting she may actually be blind, and is aware of her surroundings with her hearing to the point she detects numerous monsters before they visibly appear.
  • Four Is Death: Has several dice holding her twin tailed hair up that have the number 4 on all of their sides. This is emphasized when she slaughters several monster mooks.
  • Hammerspace: Twin Tails can hide several massive weapons such as sword in her sleeves.
  • Juggling Dangerously: Fights by juggling and throwing numerous balls, clubs, and sharp swords at enemies. Bonus points for doing it all with a blindfold on.
  • Sad Clown: Has this as a hero motif, complete with a single tear on her cheek.

    13. Great Philosopher 

Great Philosopher

Debut: Pork Cutlet Bowl (Manga)

  • Canon Foreigner: He is one of may Manga original characters who were later added to the manga.
  • Genius Bruiser: Hones his body as well as his mind, as evidenced by his ripped physique.
  • Worf Effect: Well over twice as strong as a bear and can take down a Tiger level threat with relative ease. When a large group of such monsters gang up on him though, he's left badly injured and has to be rescued by the Neo Heroes who he remarks on lacking skill, but nonetheless being stronger, faster and more resilient than him.

    16. Butterfly DX 

Butterfly DX

Voiced by: Soshiro Hori (Japanese), Joe Zieja (English)

Debut: Pork Cutlet Bowl (Manga)
A hairy hero that flies around with giant butterfly wings.
  • Attention Whore: Described as such by Forte. Indeed, he was one of the many heroes which tried to attack the monster that was devastating a police station in order to get a lot of credit, since it was an important emergency.
  • Winged Humanoid: He wears giant butterfly wings and seems to be able to fly with them.

    17. Lightning Genji 

Lightning Genji

Voiced by: Gen Sato (Japanese), Todd Haberkorn(English)

Debut: Chapter 20 (Manga), Episode 6 (Anime)
Class A hero who wears roller skates and fights using two stun batons.
  • Canon Foreigner: He doesn't exist in the original webcomic.
  • Dual Wielding: He wields two combat sticks that are charged with electricity. Both sticks are fairly short.
  • Know When to Fold 'Em: He retreated along with Stinger after realizing that what they fought was the child of an even bigger mysterious being.
  • Rollerblade Good: He uses a pair of roller skates during battles.
  • Shock and Awe: His Stun Batons harness electricity.

    20. Lightning Max 

Lightning Max

Voiced by: Soichiro Hoshi (Japanese), Ben Pronsky (English), Eleazar Muñoz (Latin American Spanish)

Debut: Chapter 25 (Webcomic), Chapter 20 (Manga), Episode 1 (Anime)

Class A hero who fights with rocket-powered shoes. He happens to be a martial artist.

  • Defiant to the End: Decides to go out swinging (or kicking in this case) against the Sea King even though he knew he didn't stand a chance.
  • Early-Bird Cameo: In the anime, he and Smile Man were sent to A-City at the start of the series to stop Vaccine Man, but they get battered and beaten by the monster with ease.
  • Extremity Extremist: Specializes in karate kicks. He uses multiple inbuilt mechanisms in his shoes that act to amplify the power of his kicks and create electrical discharges.
  • I Am Not Left-Handed: Comes back after the Martial Arts tournament to save Suiryu along with Snek, where it turns out he hadn't been wearing his special "Lightning Shoes" during the tournament.
  • Speaking Simlish: When he gets suddenly surprised, he just blurts out a string of completely random letters.
  • This Is Gonna Suck: Twice during his "fight" against the Sea King. Firstly, when he's punched all the way from the building he's standing on and through the window of the building on the opposite end of the street, he thinks "Ah, I am so dead." Secondly, when he decides to retreat from the fight only to see that the Sea King has caught up to him in the time it took for him to recover, he mutters a deadpan "Shit".
  • Tricked-Out Shoes: He wears a pair of special shoes with gunpowder and multiple inbuilt mechanisms, such as boosters, stored inside them.
  • The Worf Effect: In the tournament, both on the giving and on the receiving ends. First he defeated Lin Lin, demonstrating that A-Class heroes are stronger than the average fighter, then he was defeated in one hit by Suiryuu to show how much stronger he is.

    22. One-Shotter 


Debut: Chapter 93 (Manga)

A man who carries around a .50 caliber rifle and has some kind of eye piece that works as his scope. He is among the Heroes sent to fight the Monster Association.

  • Boring, but Practical: Improbable Aiming Skills aside, he's just a guy with a gun big enough to kill monsters, no special powers needed.
  • Born Unlucky: Apparently, his gun ALWAYS jams at the most inopportune times.
  • Cold Sniper: An unusual example as he is friendly, but seems dreary and depressed. Played with as he is prone to panic when his gun jams.
  • Friendly Sniper: He's one of the few heroes actually in the rescue team because he is legitimately concerned for the child that the Monster Association kidnapped.
  • Hoist by His Own Petard: He's nearly killed by Nyan performing a Bullet Catch and Return on his attempted shot.
  • Improbable Aiming Skills: The man saw a monster sniper several blocks away on a skyscraper. After the sniper fired, One-Shotter fired his weapon, hit the enemy's projectile in mid-air, destroyed it, hit the scope of the sniper's rifle, and blew the guy's head away. Mind you that the sniper wasn't even aiming for him so to match the trajectory of the sniper's bullet and even see the damn thing to hit it midair and STILL hit his targets scope dead center is so beyond impossible that it's ludicrous. What is in that eye piece of his?
  • Logical Weakness: Subverted and then played straight. Having a long unwieldy sniper rifle for a weapon, several monsters believe that he's helpless at close range and attempt to rush him, only for him to reveal he's so fast and skilled with it that he can shoot several targets near instantly even when they're almost on top of him. However, he only has the rifle for a weapon, so when it jams, which is apparently often, he becomes completely helpless till he can fix it.
  • Reliably Unreliable Guns: His gun apparently jams a lot, usually at the most inopportune times.
  • Not So Stoic: Comes off as cold, yet empathetic. He's not in it for the money, but to save lives. When confronted by monsters trying to melee him, he just shoots them point blank... until his gun jams and he runs panicking. Apparently he doesn't have a holdout weapon.
  • Short-Range Long-Range Weapon: His sniper rifle makes him look unable to defend himself up close, but One-Shotter is very agile and handy enough to avoid strikes and shoot monsters in the head at the same time.

    24. Green 


Debut: Chapter 96 (Webcomic), Chapter 93 (Manga)
A feeble looking hero who can control plants. He is among the Heroes sent to fight the Monster Association.

  • Body Horror: The poor guy has had plants growing inside his body since childhood, and his nervous system has actually fused with them.
  • Cursed With Awesome: Having plants growing inside you and parasitizing your nutrients is quite horrific, but Green can also control plants to fight monsters.
  • Green Thumb: Green has plants growing inside his body, and he can control them to bind monsters.
  • Reality Ensues: Because the plants growing in his body parasitize his body, he can frequently be seen imbibing in nutrient drinks after using his abilities.

    25. Crescent Eyebroll 

Crescent Eyebroll

Debut: Chapter 96 (Webcomic), Witness (Manga)
An A-Class Hero in a moon themed suit. He is among the Heroes sent to fight the Monster Association.

Voiced by: Sato Arai (Japanese), Kaiji Tang (English), Luis Daniel Ramírez (Latin American Spanish)

Debut: Chapter 20 (Manga), Episode 6 (Anime)

Class A Hero who fights with a slingshot. Defeated by Kombu Infinity. He is then defeated a second time by Garou.

  • Abnormal Ammo: Spiky balls made of shape memory gold.
  • A Day in the Limelight: In the manga version, he gets an expanded version of his fight with Garou, covering an entire issue. He does considerably better than the webcomic implied, being the first A-Class hero to injure Garou, although he still loses in the end.
  • Improbable Aiming Skills: His balls can ricochet off walls several times before hitting their mark.
  • Meaningful Name: His name can be read as testicles in Japanese language.
  • Nice Hat: Golden Ball wears a beanie.
  • Obfuscating Stupidity: Pretends to be completely drunk to make Garou let his guard down then pulls a sneak attack once they're in an alley where he can ricochet his shots properly.
  • Weapon of Choice: Golden Ball fights with a slingshot, which is way deadlier than it sounds.

    27. Smile Man 

Smile Man

Voiced by: Takayoshi Yamaguchi (Japanese), Christian La Monte (English)

Debut: Chapter 20 (Manga), Episode 1 (Anime)

A hero who wears a costume with a smile face on it and wields a large kendama as his main weapon.

  • Drop the Hammer / Weaponized Ball: He uses a gigantic kendama (a type of toy with a hammer and a ball tied to it) as weapon.
  • Early-Bird Cameo: In the anime, he and Lightning Max were sent to A-City at the start of the series to stop Vaccine Man, but they get battered and beaten by the monster with ease.
  • Ironic Name: Despite calling himself "Smile Man" and covering himself with smiley faces, he himself is rarely ever seen actually smiling.
  • Shout-Out: Smile Man has a uncanny resemblance to El Chapulín Colorado, of all things. He even has a hammer as a weapon and similar costume. His brothers, Angry Man and Crying Man, share this design.
  • Sibling Team: Smile Man has two brothers who are also superheroes.

    28. Spring Mustachio 

Spring Mustachio

Voiced by: Makoto Yasumura (Japanese), David W. Collins (English), Ricardo Mendez (Latin American Spanish)

    29. Narcisstoic 


Voiced by: Uncredited (Japanese), Patrick Seitz (English)

Debut: Chapter 68 (Manga), Episode 19 (Anime)
A self-styled "beautiful" Hero who fights with fists and everything at his disposition to his "beautiful combat art". He is among the Heroes sent to fight the Monster Association.
  • Beware the Silly Ones: He looks weird with his crescent moon-shaped head and flamboyant behavior, but he's an A-Class Hero who can fight monsters barehanded.
  • Combat Pragmatist: Sure he fights with his fists, but he's also shown bashing a monster with a concrete block and kneeing another one in the guts.
  • Dainty Combat: He prides himself on his "beautiful combat". It's anything but. The only thing that make's it "beautiful" is that fact that he tosses a rose in the air and catches it in his mouth, no matter how awkward of a posture he has to contort himself in to do so. During the time it's in the air anything goes.
  • Early-Bird Cameo: He's actually seen with other A-Class Heroes when facing the Hundred Eyed Octopus, but gets no attention like most of them thanks to being overshadowed by Flashy Flash and Tornado.
  • Improbable Weapon User: Narcisstoic seems to use anything available to him. He is seen using a concrete block to bash a monster's head in, and later is seen to have been using a street sign as a pole.
  • Rapid-Fire Fisticuffs: He uses this technique against a monster.
  • Something About a Rose: Narcisstoic is introduced with a rose in his mouth. Impressively, he drops it and manages to defeat several monsters before it touches the ground, catching it at the last moment with his mouth again.
  • Unknown Rival: To Amai Mask. He introduces himself as Amai Mask's rival, but Amai Mask completely ignores him and instead focuses on Feather.

    30. Peach Terry 

Peach Terry

Voiced by: Uncredited (Japanese), Sam Riegel (English)

Debut: Lost Cat (Manga), Episode 19 (English)

    31. Forte 


Debut: Pork Cutlet Bowl (Manga)

A hero who listens to music and fights with the rhythm.
  • Awesome, but Impractical: His fighting style isn't all that original, but it's apparently effective enough to land him in A-Class. Having his headphones on makes it impossible for him to hear what's coming up behind him though. Such as a car.
  • Amusing Injuries: Hit by a car driven by the Blizzard group. He had it coming.
  • Berserk Button: Suggesting that working up a rhythm to fight seems pointless.
  • Dance Battler: Fights his enemies by dancing to the beat of the music he listens to.
  • Know When to Fold 'Em: Gave up on his revenge plot after seeing Saitama unharmed after being thrown by Tornado.
  • Poor Communication Kills: He got hit by the Blizzard Group's car because he couldn't hear Saitama's warnings.
  • Small Name, Big Ego: Demanded respect from Saitama for being his senior insofar as being a resident of the same apartment, despite being a year younger than him.

    32. Shadow Ring 

Shadow Ring

Debut: Chapter 93 (Manga)
A hero dressed as a ninja, who wields a sword and uses a lot of typical ninja techniques. Under the garb is a woman, and she is among the Heroes sent to fight the Monster Association.
  • Compressed Hair: How exactly she gets her pigtails to not bulge under the hood is unknown, but impressive.
  • Girlish Pigtails: Under her mask and hood, she's shown to keep her hair in a pair of large pigtails.
  • Hidden Buxom: After Nyan's attack shreds her outfit, she's shown to be fairly busty under her clothes.
  • Highly Visible Ninja: Wears stereotypical ninja garb in broad daylight, but makes up for it by being very fast and surprisingly stealthy to get in her enemy's blind spots.
  • Multilayer Façade: Underneath her face-concealing mask and hood she wears a Domino Mask.
  • Mysterious Past: The only thing we know about her is that she isn't from Flashy Flash's village which is also a mysterious place. She is incredibly nervous around Flashy Flash as their villages are apparently rivals. If Flash was one of his village's more nasty members, he might have had it out for her. Despite his respect of her, she doesn't seem to want to take the risk of ticking him off, so she quickly excuses herself from his presence (that or she has a crush on him or something).
  • Ninja Brat: It is implied Shadow Ring is still inexperienced, especially compared to Flashy Flash.
  • Ninja Log: Uses one to fake having her head sliced open, though judging from her relief it was a close miss.
  • Samus Is a Girl: Her ninja garb does a good job of hiding her face and body, to the point that if it weren't for Flash offhandedly noting it, it would be easy to assume she's a man.
  • Super Speed: While nowhere near the level of Sonic or Flash, she pulls some pretty impressive feats of speed off while blitzing monsters in the Monster Association raid.
  • Weak, but Skilled: She doesn't have a lot of raw power, as she gets some of the lowest "scores" while fighting Rhino Wrestler, but her skills as a ninja are such that even Flashy Flash praises them.

    33. Doll Master 

Doll Master

Debut: Pork Cutlet Bowl (Manga)

    34. Feather 


Debut: Chapter 104 (Webcomic), Chapter 93 (Manga)
A dark long haired hero, with a fabulous costume and impossibly sharp claws.

    35. Air 


Debut: Disaster Level (Manga)

    36. Chain'n'Toad 


Voiced by: Koichi Soma (Japanese), Robbie Raymond (English)

Debut: Chapter 95 (Webcomic), Pork Cutlet Bowl (Manga)
A martial artist who wears a frog mask to make up for how plain he looks.
  • Chain Pain: Carries a chained weapon called a kusari-gama to fight with.
  • Kid-Appeal Character: In-universe. Wearing that headgear makes him a little bit more popular amongst children.

    37. Snakebite Snek 


Voiced by: Shin-ichiro Miki (Japanese), Kirk Thornton (English), Edson Matus (Latin American Spanish)

Debut: Chapter 16 (Webcomic & Manga), Episode 5 (Anime)

The lowest ranking A-Class hero.

  • Animal Motifs: Wears a snakeskin suit, utilizes a snake-based martial art style in combat (with a snake-shaped aura appearing around his hands when he uses his attacks), and his name is Snek. He also has a rather treacherous personality.
  • Arrogant Kung-Fu Guy: Thought he could newbie-crush Saitama... despite being told a few minutes ago that Saitama broke every single physical record in the Hero Association. He gets a little better by the tournament arc and accepts that there are people out of his league, but it's still there to an extent.
  • Bullying a Dragon: His attempt at hazing Saitama doesn't quite work out as well as he hoped it would. He does at least end up better than most of Saitama's foes.
  • Butt-Monkey: Poor guy gets humiliated in one way or another whenever he appears. He does get a moment to shine in the tournament arc in the manga. He gets to kick some ass and even gets a chance to be heroic in a fight against impossible odds. Like the other heroes there, he gets his ass handed to him easily, but he at least gets to show he's no coward.
  • Cowardly Lion: Still tried to fight the Sea King even though he knew he wouldn't be able to harm it.
  • My Suit Is Also Super: His Snakeskin suit is actually made for him by the Hero Association from the skin of a monster he defeated. This suit protects Snek from suffering very serious injuries because it is highly resistant to any form of attack.
  • Overshadowed by Awesome: While he did earn his A-rank, he's still the weakest within that rank.
  • Throw the Dog a Bone: He gets one in the manga-exclusive tournament arc. In the first match his opponent assumed he was weak since he was the lowest ranking hero, but Snek defeats him easily. Afterwards he saves Suiryu's life along with Lightning Max, while he's wearing a special suit capable of deflecting attacks.
  • Underestimating Badassery: He's been on both ends of this. He underestimated Saitama and tried to newbie-crush him because he was only C rank, despite being told that he had just broken every record in the physical exam. And in the manga-exclusive tournament arc, his opponent assumed he was weak since he was the lowest ranking hero. Snek is quick to correct that he is only the lowest ranking hero in A-Class.

    40. Suiko 

A diligent young martial artist, she is Suiryu’s younger sister, Suiko wants to prove herself to be superior to her big brother since Suiryu has a very good reputation as a strong martial artist despite being a carefree playboy, with Suiko being very serious about martial arts, she hates that slacker image being associated with her family’s legacy.
  • Fish out of Water: It is implied that she spent so much time training that she is out of touch with the outside world which is why she joined the Hero Association which has fallen on hard times instead of the Neo Heroes who are currently overtaking them.
  • Hard Work Hardly Works: While her brother, Suiryu, is a carefree playboy and strong enough to be in the lower ranks of S-Class, Suiko is a diligent martial artist who is strong enough to be in A-Class, but not S-Class material... yet at least. Although this is downplayed since she is still rather young.
  • Mythology Gag: In the drafting phase for Suiryu ONE stated he initially planned for the character to be a drunken master martial artist but the concept was dropped; Suiko is then created and ONE places the drunken master schtick on her instead.
  • Strong Family Resemblance: She looks a lot like her older brother who was already a bishonen.

    Heavy Kong 

Heavy Kong

Voiced by: Uncredited (Japanese), Chris Tergliafera (English)

Debut: Chapter 20 (Manga), Episode 6 (Anime)

B-Class Heroes

They are the third highest rank in the Hero Association. There are 101 heroes in this class.
     1. Fubuki / Hellish Blizzard 


Voiced by: Saori Hayami (Japanese), Laura Post (English), Jocelyne Robles (Latin American Spanish)

Debut: Chapter 47 (Webcomic), A New Wind Blows (Manga), Episode 6 (Anime)

Blizzard is the number 1 B-Class Hero of the Association and Tornado's younger sister. Also an esper, Blizzard is overshadowed by her older sister and has confidence problems because of that. She built a mob of Yakuza-like underlings among the B-Class to make herself feel better, but an encounter with Saitama shatters her illusions.

  • Adaptational Attractiveness: Far more attractive in the more detailed reboot. In the original she was androgynous at best; in the redraw she has a much more curvy figure.
  • Almighty Janitor: Blizzard remains in B-Class despite being worthy of the higher ranks of A-Class. It's explained that she has low self-confidence and fears not being the number 1.
  • Asskicking Equals Authority:
    • She uses her high rank in the B-Class to amass a mob-like organization of lower ranking B-Class heroes and rule over them like a yakuza boss.
    • A Volume 9 omake has the Blizzard Group pooling money to get a car, mostly through part-time jobs (having misinterpreted Blizzard's idea). Blizzard, however, was out bounty hunting (which was what she actually meant by checking out flyers) and earned over a third of the required funds by herself. She EARNED her rank.
  • The Atoner: She is this after revealing her Dark and Troubled Past, wanting to change herself and be a better person.
  • Big Little Sister: To Tornado. Child Emperor mistakes her for the older sister, and so does Do-S.
  • Born Unlucky: Feels that she is doomed to always pale in comparison to her sister. The fact that in her childhood she was always being bullied by the kids, and that no one wanted to play with her because her older sister was known to be dangerous by other kids, didn't help her state of mind. However, it is revealed before her psychic powers manifested properly that her older sister received WAY worse than her.
  • Break His Heart to Save Him: Tells her subordinates that she's disbanding the Blizzard Group and coldly tells them that they're weak. It's obvious she's doing it to protect them from Tornado.
  • Breakout Character: Became very popular shortly after her debut to the point where she's had original chapters focusing on her or the Blizzard Group, had a brief cameo in the first season of the anime, and got a special OVA focusing on her.
  • Character Development: She starts off as a haughty, conceited jerk who is clearly taking out her frustrations over her sister on other people by either forcing them to be her goons or threatening them. After befriending Saitama she genuinely wants to change herself, starting with finally standing up to her sister.
  • Clothing Damage: In the fight with Do-S the back of her dress is ripped when the monster attacks her from behind.
  • Combat Stilettos: Though since she can do Power Floats with ease she can get away with it. It turns out one of her hobbies is collecting high heels.
  • A Day in the Limelight: Has had a few special chapters focusing on her or the Blizzard Group, as well as the fifth OVA.
  • Declining Promotion:
    • Despite her psychic powers making her more than qualified to be in the upper A-Class ranks, she stays in B-Class to control the B-Class heroes so she can try and surpass Tornado, and it's impossible for her to reach A-Class Rank 1 with Atomic Samurai's three disciples taking Ranks 2-4 and Amai Mask taking Rank 1.
    • After fighting with her sister and then the Blizzard group declaring they would get stronger to be worthy of being her underlings, Blizzard has decided to start moving up the A-Class ladder.
  • Defrosting Ice Queen: Part of her arc, going from distant and bossy to a more compassionate, caring person.
  • The Don: Sort of — Class B has become an almost Mafia-like system due to all the strong Class Bs being loyal to her, and basically forcing the other heroes into working in B-Class for the rest of their career since she kept the number 1 spot.
  • Early-Bird Cameo: Shows up in the anime at the end of episode 6 receiving word of Kombu Infinity in Z City.
  • Even Evil Has Standards: In the past, when Vice-President Psykos wanted President Blizzard's evil organization to Kill All Humans instead of just Take Over the World, the rest of the organization was opposed because that was too evil even for them. Somewhat subverted for past-Blizzard herself, though, as she only opposed Psykos just because there'd be no normal humans left for her to look down on if they did that.
  • Evil Versus Oblivion: She was this in the past. When Psykos wanted to change their club's goal from Take Over the World to Kill All Humans, Blizzard was opposed because then there'd be no one left for Blizzard to look down on. The disagreement quickly became violent.
  • Family Eye Resemblance: She has the same green eyes as her sister Tornado, showing that they are related, although Blizzard's eyes are a bit darker.
  • Family Theme Naming: Blizzard and Tornado are named after windstorms.
  • Friendless Background: As a child she couldn't make any friends, her sister having scared away everyone in the neighborhood.
  • The Glorious War of Sisterly Rivalry: With her power, she was meant for great things and would've been the number 1 of many things in life. Sadly, her sister came first, and being a super-powerful Esper in her own right, she completely eclipsed her in everything. This causes a little friction in that Blizzard firmly believes the power has gone to her sister's head and made her the aloof, alone jerk she is today.
  • Heel–Face Turn: She's a genuine albeit flawed hero in the present day. In the past, as a student, she was president of a club of super powered people whose goal was to take over the world. Exactly why it was disbanded isn't mentioned. Maybe it simply ended after the violent schism between Blizzard and the vice-president, Psykos.
  • Heroic Willpower: She is the first person that is able to resist Do-S's mind control.
  • Inferiority Superiority Complex: Feels very insecure about her abilities, so she stays a B-Class while surrounding herself with weaker subordinates, despite having abilities that could easily put her in the top ten of Class A. Hilariously, even after accepting that Saitama was far stronger than her, she still refers to him, and by association Genos, as her underlings.
  • Kirk Summation: Gets one from Saitama, although it's just him telling her that no matter how many B-Class heroes she has below her, they won't be able to save her from an overpowering monster. Sure enough, while she can hold her own against Demon-level Monsters by herself, when dealing with an outbreak of mysterious beings affiliated with the Monster Association she finds herself at her wits' end against Do-S when her subordinates and other HA affiliates threaten to overwhelm her. Saitama's cryptic words even come ringing back into her mind during the whole shebang, although she angrily rebuffs the mental recall. It happens again when Garou appears and thoroughly trounces the S-Class heroes in quick succession. All she can do is hide, knowing she isn't strong enough to even be worth Garou's attention, but not ever being certain.
  • Knife Nut: Carries around a box cutter in case she needs to resort to melee.
  • Lady of War: The elegant and professional leader of B-Class who is more than qualified for A-Class, she has a graceful style of fighting using psychokinesis.
  • Little Sister Instinct: When Do-S says that she wants to use Blizzard to lure Tornado and harm her, she becomes enraged and beats Do-S up.
  • Meaningful Name: In one of the flashbacks, someone calls her "president Blizzard" (Fubuki means "Blizzard"), implying that just like her sister's, her Hero name is also derived from her actual real name.
  • Mind over Matter: Although not nearly as powerful as her sister Tornado, Blizzard is a skilled esper. She has been shown to mainly use her psychokinesis when fighting an opponent, throwing rocks, pebbles and various other items at her target, or manipulating their surroundings to her advantage to impede or crush them. Through her constant research and quest for versatility and innovation, Blizzard has learned notions that not even her sister knows about, such as that resistance to psychokinesis is directly linked to one's willpower.
  • A Mother to Her Men: While her methods to recruiting them are a bit questionable, it's clear that most of her subordinates follow her because they WANT to. She even says she didn't mind bringing in dangerous bounties as it was for the Blizzard Group and genuinely cares about them.
  • Ms. Fanservice: Her clothes cover a lot of her body, but they still make her curves visible. She's gorgeous and there's frequently a lot focus put on her body. An illustration in Volume 9 shows her in her underwear, and multiple chapters' covers have her posing in a bikini.
  • Overshadowed by Awesome: Make no mistake, Blizzard is one of the most powerful people on the planet (and one of only a handful of people with psychic abilities), but she's unfortunately outclassed by her far more talented sister. And obviously by Saitama.
  • Picky Eater: Counts calories when ordering at a restaurant.
  • Pretty in Mink: Often wears a fur jacket she uses as a Coat Cape.
  • Psychic Link: She can sense her sister's presence, and could tell when she was incapacitated by the Monster Association.
  • She's Got Legs: It seems to run in the family.
  • Shrinking Violet: When she was little, no doubt due to her abilities. And her sister.
  • The Smurfette Principle: One of the very few women in the Hero Association.
  • Strong Family Resemblance: If you look closely, Blizzard looks quite similar to Tornado, from the green eyes to the face structure. It's implied that Tornado would have had a similar face to her sister, had she grown up normally.
  • Sugar-and-Ice Personality: Fittingly, she's typically cold and professional like how a mafia don would act. However, she also has a soft side, like when she smiles for Lily when it's clear she was worried about what Blizzard was doing to earn money for the group.
  • They Really Do Love Each Other: She may think Tornado is a crazy psychopath out to ruin her life, but she still does love her. When Blizzard at one point goes all out against her sister she panics at whether she might have actually gone too far and hurt her.
  • Tsundere: Aside from her Sugar-and-Ice Personality, Blizzard can get easily irritated by Saitama who often berates her for having an ego. Still, in her private moments she does acknowledge just how powerful Saitama is and is seen to hang out with him and his friends.
  • Underestimating Badassery: Blizzard keeps underestimating Saitama, treating him as if he should serve her, even after knowing just how strong he is. Not that it works in her favor. Still, Saitama and Blizzard do have a relatively friendly relationship.
  • Vitriolic Best Buds: Despite Blizzard insisting Saitama is her underling and Saitama being annoyed with Blizzard bugging him to join the Blizzard Group, it's clear the two of them have developed a sense of camaraderie.
  • Weak, but Skilled:
    • Her Esper Powers count as this, as she manages to defeat Psykos by diverting a psychic attack she otherwise couldn't handle by using a spinning barrier of carefully controlled psychic waves. However, her sister, Tornado, figured out how to perform the same trick a long time ago.
    • Her physical power-rating, as shown by Child Emperor's device, was a mere 19, way below C-Class. However, her psychic abilities can't be measured and those are the real reason she's so powerful.
  • Willfully Weak: Or willfully in a lower rank. Blizzard has power equivalent to a high A-Class, but doesn't believe she could be at the top. Tornado surmises she has the potential to be S-Class alongside her, but believes there's something mentally holding back her potential. Tornado incorrectly surmises it's her friends and associates, it's actually fear and feelings of inferiority to her older sister.
  • Yakuza: A heroic example. Because Blizzard remains in the number 1 spot in this class and prevents any other heroes from advancing to A-Class, she controls the B-Classes in this type of manner.
  • Younger Than They Look: Played with. She is 23 and looks her age, but is actually the younger sister of Tornado, who is 28 despite looking like a child.

Voiced by: Taito Ban (Japanese), Billy Kametz (English)

A young hero and former member of the Blizzard Bunch.

  • Canon Foreigner: He doesn't exist in the original webcomic and debuts in a manga bonus-story.
  • Expy: He shares many similarities with the young Saitama. Both start as average guys that want to become stronger and real heroes.
  • Hard Work Hardly Works: After reaching B-Class he begins losing self-confidence, believing that he and other average people have limits and cannot keep up with people who have natural born talent. He changes his mind after Saitama saves him.
  • I Just Want to Be Special: Wanting to become a hero, Glasses trains hard in order to become one. He was just an office worker.
  • Megane: It's his most recognizable quality, as well as his hero nickname.
  • Non-Action Guy: Garou originally thought he was one and targeted him as the weak link in Death Gatling's hero team. He winds up surprised when Glasses manages to counter his attack and fight back, and before Garou can correct himself and get serious he's forced on the defensive by the other heroes again.
  • Took a Level in Badass: He reappears with other heroes as a part of a team led by Death Gatling to ambush the injured Garou. He acts as support and fighter hero for the group, with various roles such as refilling the arrow bag for Shooter, but shows he is capable of defending himself when Garou attacks him. And even when Garou defeats him and the rest of the team, Glasses manages to send an emergency signal to Genos, who promptly arrives.

    29. Double Hole

A nose-themed martial art practitioner, who also wears a special nose mask.
  • Blow You Away: Double Hole inhales deeply, before releasing the air as a powerful wind to knock away monsters. It is powerful enough to create a visible crater upon impact.
  • Cool Mask: It is stretching the definition of cool, but the mask is a weapon that creates powerful gusts of air.

  • Anime Hair: In his new "reborn" form, his hair is combed into large spikes.
  • Boxing Battler: He mainly fights with his fists, protected by boxing gloves.
  • Cool Shades: Sunglasses hide his eyes constantly. His first ones were boxy, but the new ones during the Monster Raid arc possess a more dynamic shape.
  • Good Thing You Can Heal: Like Genos, he can shrug off a lot of damage thanks to being a cyborg that can be easily repaired.
    "Snake Fist" Snek: Calm down. He's a cyborg. He's not necessarily dead.
  • Leeroy Jenkins: During the Sea King's attack on the shelter, he rushed in alone to attack him instead of waiting for Snek's signal, and was subsequently Impaled with Extreme Prejudice.
  • Nice Guy: Presumably, although we haven't seen much of his personality. It's even in his name.
  • Took a Level in Badass: In a fashion, he has modified his cyborg body since the fight against the Sea King.

  • Epic Flail: Needle Star wields a meteor hammer with great skills, as he can aim for specific spots but effortlessly redirect the metal ball.

  • Oral Fixation: He is seen chewing a gum during his introductory fight.

    71. Captain Mizuki 

Captain Mizuki

A hero with a track and field motif. She is among the Heroes sent to fight the Monster Association.

  • Amazonian Beauty: She's tall and athletic enough that her muscles are visible, yet still noticeably curvy and feminine.
  • Charles Atlas Superpower: Not to the extent of Superalloy, but she's strong enough to fling a man-sized monster like a flail, and crush two more with arm and thigh strength while grappling. The numerous medals she wears suggests she took the gold in many competitions due to this.
  • Crippling Overspecialization: Downplayed. Her track and field and wrestling moves do cover a lot of situations, but as soon as she is forced out of her comfort spot, she cannot do anything.
  • Expy: Of Michelle Jenneke.
  • Grievous Harm with a Body: One of her techniques is to impale a monster with her trick weapon in javelin form, then transform it into a handle hooked inside the monster to recreate a hammer throw, bashing monsters around her at the same time.
  • I Know Madden Kombat: A lot of her combat maneuvers are based on track and field activities.
  • Ms. Fanservice: A lot of panels focus on showing off her muscular yet feminine figure, especially her thighs and rear. She even gets a chapter cover in the manga specifically to show her off.
  • Murderous Thighs: Her legs are strong enough to crack open a watermelon monster.
  • Passionate Sports Girl: All her moves are based off track and field events as well as a few grapple-based wrestling moves.
  • Sensual Spandex: Her outfit is basically a sleeveless crop top and very short shorts, both hugging her body tightly. Murata even redrew some shots of her in chapter 94 to make her shorts even shorter.
  • Statuesque Stunner: She towers over several other male characters and boy, is she a beauty.
  • Swiss Army Weapon: She carries around a baton that can transform into a variety of tools that help her fight as if she was performing Olympic competitions.

    74. Triple-Staff Lilly 

Triple-Staff Lily
Voiced by: Ari Ozawa (Japanese), Erika Harlacher (English)

The only woman that works under Blizzard in her group. Lily wields a staff that breaks into three pieces.

  • All There in the Manual: A lot of information about her was revealed on Murata's Twitter feed.
  • Art Evolution: Started out looking like a generic background character but has a far more distinct design in later chapters.
  • Ascended Extra: Didn't speak a word until the Blizzard Group special chapter.
  • Canon Immigrant: Began as a manga-only character, but has since appeared in the webcomic.
  • Fangirl: Of Blizzard, whom she hero-worships.
  • Foil: In a way she is one to Genos. Both are teenaged Hero-Worshipper towards another hero who is much more powerful than them. Both Genos and Lily's heroes, Saitama and Blizzard respectively, end up taking them under their wing, with Genos being Saitama's disciple and Lily joining the Blizzard group.
  • Fake Boobs: Murata revealed that if her bust seems too big for a 14-year-old, it's because she is using a brassiere pad due to her admiration towards Blizzard.
  • Little Miss Badass: She's a B-Rank at fourteen.
  • Multicolored Hair: Black with bright blue highlights, meant to evoke multi-colored lilies.
  • Sharp Dressed Woman: A pinstriped suit no less.
  • Simple Staff: Wields a sansetsukon.
  • The Smurfette Principle: The only woman in the Blizzard Group aside from Blizzard herself.

    81. Tank-Top Blackhole 

Tank-Top Blackhole
Voiced by: Atsushi Imaruoka (Japanese), Joshua Tomar (English), David Allende (Latin American Spanish)

A top class B hero. It is uncertain exactly which rank he has on the top.

  • Blatant Lies: At one point when attempting to get the people to hate Saitama, he tries to make it seem like Saitama was going to lash out against him even though Saitama hadn't made a single physical movement.
  • Bullying a Dragon: Running a smear campaign against Saitama can go two ways: You either get ignored or get destroyed.
  • Charles Atlas Superpower: Blackhole is a rather strong individual, boasting a grip strength of 200 kilos.
  • Curb-Stomp Battle: Saitama dispatches him as easily as you'd expect.
  • Dirty Coward: When Saitama catches his hand and squeezes, Blackhole immediately says that he gives up and that he's sorry for lying. Although given how strong Saitama is, it might be causing legitimate pain...
  • Jerkass: When Saitama had prevented a meteor strike but hadn't been able to prevent its fragments from decimating a lot of the city note , he takes this as a chance to prop himself up by tearing down Saitama.
  • Jerkass Has a Point: Saitama could have avoided a great deal of destruction if instead of smashing the meteor with brute force he harnessed his force to push it back out into space. You really can't blame the citizens for being angry considering the resulting debris destroyed their entire town.

    Other Minor Heroes 

93. Mushroom
some caption text

  • Ambiguous Gender: Mushroom's gender is not specified and no one seems to know what it is.

C-Class Heroes

They are the lowest and weakest class in the Hero Association. Because of the large amount of heroes in C-Class, if any hero is inactive for one week, then they are removed from the Hero Registry. In order for them to maintain their quota, they usually deal with minor crimes such as purse snatchers, robbers, and street assailants. There are a total of 390 heroes in this class.
    As a whole 
  • Becoming the Mask: A lot of C-Class heroes, especially in the lower rankings, are encountered in crowds wearing Civvie Spandex or straight-up normal clothes. Some are even shown to have other jobs. It seems to imply that C-hero work is more or less an Uber-Cops and only becomes a full time job when you get enough work or become popular enough that being your alter ego isn’t profitable anymore.
  • Cowardly Lion: If a group of civilians is in danger, they'll try to help the people despite their fears.
  • Crouching Moron, Hidden Badass: Despite some of them being ridiculous, they're still capable of fighting back as long as the threat isn't too powerful for them.
  • Glory Seeker: Most of them are more concerned about ranking up and getting attention.
  • Know When to Fold 'Em: If the threat is too dangerous for them, some of them know when not to get involved.
  • Non-Powered Costumed Hero: Many of them seem to have no superhuman powers at all, Mumen Rider being the most obvious example (although his powers may have been overshadowed by the strong enemies he's faced onscreen).
  • Ragtag Bunch of Misfits: Most or some of them will team up to deal with a threat. Eyelashes describes them as the "alliance of C-Classes who often act in groups".

    1. Satoru / Mumen Rider 

Mumen Rider

Voiced by: Yuuichi Nakamura (Japanese), Robbie Daymond (English), Dan Frausto (Latin American Spanish)

(while bleeding heavily) It's not about winning or losing! It's about taking you on, RIGHT HERE, RIGHT NOW!

The top-ranked C-Class hero, Mumen Rider (real name Satoru) is a bike rider who earned his rank by doing just about any good deed he sees. Unlike most other heroes, he has no superpowers nor any real fighting ability, but more than makes up for that with courage and willingness to face off against any threat no matter how great or small.

  • Action Survivor: By the standards of the series, he's just a completely average guy with a bike — one that isn't even especially tricked-out. It's just a good, solid multi-terrain, mid-range bike. He has no special powers nor is he a particularly amazing fighter, but what he lacks in strength he makes up in resolve (as long as he can reach them).
  • Almighty Janitor: Played with. Apparently he's done a lot of heroic things, allowing him to move up to B-Class, but he refuses to do so. It doesn't translate to him being more powerful though, it just means he's earned a place in B-Class, but would rather continue helping in C-Class.
  • Authority Equals Asskicking: Subverted for the most part, but as far as C-Class strength heroes go he's this, and that's mostly because he stops EVERY crime he sees while on patrol. All of them. Yet he's failed to save any person in the series (mostly what happens is the antagonistic thing of the week simply concentrates on beating up Mumen Rider while the original victim escapes). Nonetheless, his heroic resolve is quite amazing.
  • Boring, but Practical: He may not be a great fighter, he may not have any special powers, and he may just ride a normal multi-terrain bike, but he saves several people in City A during the Dark Matter Thieves attack, simply because he's a very good cyclist and his bike allowed him to search the ruined city for stranded survivors faster than someone could on foot, and his bike could navigate the ruins better than a motor vehicle.
  • By-the-Book Cop:
    • When attempting to hurry to the scene of the battle to fight the Sea King, he cursed his luck at having to stop at a red light. On an abandoned street, where no one would watch if he ran the light and there was no traffic to worry about, and he's responding to an emergency situation. He's following the law, but this also falls into Honor Before Reason.
    • So much so that he even stops Tanktop Master, a S-Rank hero, from beating the life out of Garou (by jumping into his attack, no less!) because it would be murder if he killed a street punk like that when Garou looks to have lost. Of course, Garou returns the favor by smashing his head into the concrete, but hey, you gotta give Mumen Rider props for his unwavering determination to do things legally.
  • Car Fu: A variation; his "Justice Crash" is just him running his bike into someone. It might work for a normal mugger and regular humans, but not much other than that.
  • Charles Atlas Superpower: Make no mistake, he's a lot stronger and much more durable than most humans. Even C-level Heroes are way above the average strength and toughness level of civilians according to Child Emperor. The problem is that most of the threats he faces are higher than Tiger level because he refuses to back down even if his opponents can annihilate skyscrapers with a single punch.
  • Chronic Hero Syndrome: He will always try his hardest to fight the monster of the week, no matter how powerful they are or how hopeless the situation may be. He never gives up the fight, which earns him Saitama's respect.
  • Declining Promotion: He declines the promotion to B-Class because he says he's not fit to be in that class.
  • Determinator: He is incredibly determined and never backs down, even at the cost of his own life. He is perfectly willing to give his own life if it means protecting innocent people from evil, even when it is clear he has absolutely no chance of success.
  • Determined Defeatist: As shown by his speech to the Sea King.
    Mumen Rider: I know no one expects much from me. And I know better than anyone... how useless a C-Class hero is! I know I'm too weak even for Class B! I know more than anyone else... that I'll never beat you! But I must fight you anyway. I'm the only one left! It's not about winning or losing! I just have to stand here and face you!
  • Doomed Moral Victor: He and everyone know that he can't win against the deep sea monster kings or intergalactic conquerors that he goes up against, but it's his determination and fearlessness against such impossible odds that earn him the respect and admiration of the populace (and Saitama).
  • Exactly What It Says on the Tin: He used to ride a motorcycle, but he lost his license for going over the speed limit while helping people, hence his hero name.
  • Expy:
    • Of Kamen Rider, if that wasn't obvious.
    • More subtly of pre-training Saitama as well. He has the same convictions at heart, refuses to give up despite the overwhelming odds (though it worked out better for Saitama even before his training), and always does the right thing... though Rider takes it a bit overboard with his by-the-book thing. It's probably why the anime gives him a surprisingly large number of scenes despite not being able to actually do anything in major fights, and is why he's able to sympathize with Saitama far more than any other hero outside of Genos.
  • Failure Hero: Played for laughs.
  • Fan of the Underdog: The only person to thank Saitama for defeating the Sea King (granted, one of the few who knew he was only pretending to be a fraud).
  • Foil: To Saitama. Saitama has the strength of a demi-god (or maybe even a full god); Mumen Rider is just an ordinary guy who rides a bike. Saitama receives almost zero respect from the Association and the world at large; Mumen Rider is loved and seen as an inspiration. Saitama is a "hero for fun", while Mumen Rider is an Ideal Hero who fights For Great Justice. Saitama is bored and often isolated as a result of his abilities; Mumen has drive to spare and regularly engages with all different kinds of people partly thanks to his abilities. Both look up to the other, but Mumen would likely turn Saitama's power level down in an instant, if offered it. The opposite may not be the case.
  • For Great Justice: His sub-title is "The Cyclist for Justice", most of his attacks incorporate justice in the names, and he even named his bike "Justice".
  • Hero Stole My Bike: Played with. Having a bike is his gimmick, and every time he gets trashed his bike usually gets bent horribly out of shape along with him, so he's given a new one.
  • Heroic Resolve: Actually goes up against the Sea King, knowing full well he's not strong enough to stop it, and delays it long enough for Saitama to show up and do his thing. Hell, Saitama even compliments him on it and tells him that in his eyes, he'll always be a true hero, no matter what rank he is.
  • Hold the Line: His entire job and a main part of his philosophy. He knows that he is weak (especially since he lost his main weapon, a motorcycle, when he lost his license for recklessly chasing down monsters). However, he holds fast to the idea that heroes have to stand up and fight, no matter the odds, because that's what being a hero means. He ends up holding the line just long enough for Saitama to arrive on the scene before there were civilian casualties.
  • Ironic Nickname/Meaningful Name: "Mumen" directly translates to "License-less". It's ironic because he is a licensed and reputed hero. It's also meaningful because his license is entry-level (C-Class) and he never takes a promotion because he knows he's not skilled enough. He also lost his motorcycle license, which made him ride a bicycle in the story. His name is also a play on 'Kamen Rider', one of the iconic Japanese heroes.
  • Joke Character: Much like Saitama, his fights are hilariously one-sided, but with him on the short end. He's so pathetic combat-wise that Sea King doesn't even bother putting in any effort to fighting him, simply flailing him about, which is enough to hurt him.
  • Made of Iron: For someone with no obvious powers, Mumen Rider is able to take a lot of punishment from the Villain of the Week and still manage to survive.
  • Meaningful Name: "Mumen" means "licenseless". He rides a bike rather than a car or motorcycle because he doesn't have a driver's license.
  • Nice Guy: He really is the genuine article, taking no offense when people move above him and being a helping hand to those who need it under him. Solid trooper.
  • Opaque Nerd Glasses: Has them whenever he's not wearing his helmet.
  • Reality Ensues: He gets his ass kicked every time he fights. It doesn't matter how pure his attempts of heroism are or how strong his Heroic Resolve is. He's still a human with limited fighting skills facing off against monsters that are way out of his league, leading to him suffering one Curb-Stomp Battle after another. Downplayed, as he is aware of his weakness and this is why he chooses to remain in C-Class rather than rise up to B-Class.
  • Running Gag: Throughout the manga he appears at the scene, only to get quickly taken out off panel. This gets subverted in the Sea King arc.
  • Signature Move: Justice Crash. He simply rides his ride into his opponent and jumps off it at the last second, landing in a fighting stance. Supposedly it worked better when he still drove a motorcycle.
  • Too Long; Didn't Dub: The Viz translation kept his name as "Mumen Rider", even though "License-less Rider" would have been a perfectly acceptable translation. The fact that he's a Kamen Rider reference might have had something to do with it. That and the fact that he has the letter M on his chest. Averted in the Latin American Spanish dub, when he was renamed literally as Ciclista Sin Licencia.

    3. Super Bondage Shell 

Super Bondage Shell

A Hero whose specialty is tying up monsters. He is among the Heroes sent to fight the Monster Association.

  • Bound and Gagged: His special technique is to rapidly bind monsters in a compromising position and leave them to be picked up by others.
  • Creepily Long Arms: He's tall, and his arms look to extend all the way to his knees.

    6. Tank-Top Tiger 

Tank-Top Tiger

Voiced by: Hiromu Miyazaki (Japanese), Chris Tergliafera (English), Hector Moreno (Latin American Spanish)

A C-Class superhero, rank 6, and the younger brother of Tank-Top Blackhole.

  • Arrogant Kung-Fu Guy: He uses a tiger-like fighting style, which is an actual Chinese kenpo. He is confident in his own power and looks down upon superhero newbies, making him quite arrogant and hostile.
  • Driven by Envy: He's a very sore loser who refused to believe Saitama jumped ranks past him after the meteor event.
  • Glory Hound
  • Jerkass: After Saitama destroys the Giant Meteor, he is taking a walk through the damaged Z-City when Tank-Talop Tiger shows up, accusing Saitama of lying and cheating.
  • Kick the Son of a Bitch: Prone to receive this a lot, though not many pity him.
  • Laser-Guided Karma: Sometime after trying to smear Saitama, he received a demotion to rank 13.
  • Muscles Are Meaningless: He's as muscular as some of the S-Class heroes, but is still C-Class.

    66. Food Battler Futoshi 

Food Battler Futoshi

A fat costumed Hero who fights by powering himself up with food. He is among the Heroes sent to fight the Monster Association.

    89. Red Muffler 

Red Muffler

A hero that gets his name from the red scarf he wears.

    133. Gearsper 
A hero with some level of psychic power. He's among the heroes sent to fight the Monster Association.

  • Cool Helmet: He wears some kind of cycloptic helmet over his face.
  • Flechette Storm: Manages to create a barrage of sharp rubble the size of whole people from the surrounding buildings to attack Nyan. Too bad the cat monster manages to avoid them without a scratch.
  • The Load: Is shown to be completely useless in a fight, and his psychic powers are unreliable to the point of nonexistence. His inclusion in the rescue mission may only be to indicate how incompetent the higher ups are for picking him. Later subverted. His psychic power is later used to find all the exits of the Monster Association making for a useful support role. Then he's shown to actually have some telekinetic ability on the same level as Tornado when Nyan attacks, albeit it overwhelms him.
  • Power Incontinence: Whatever amount of psychic power he has apparently doesn't work reliably, as he had to desperately concentrate when being attacked by a group of monsters, and was rescued by Okamaitaichi and Bushidrill while believing it was his own power that saved him. Later seen in the opposite direction when he's able to wield a telekinetic power against Nyan to such a degree, Blizzard briefly mistakes it for her sister, but it quickly overwhelms and knocks him out.

    300. Poison 


A C-class Hero who uses poison to defeat monsters. He is among the heroes sent to fight the Monster Association.

  • Boring, but Practical: Poisoning your enemies by simply grazing them with a small knife isn’t exactly the most exciting way of defeating monsters but it gets the job done.
  • Combat Pragmatist: Heroes are meant to kill monsters, so he does so in the easiest and simplest way by shallowly cutting them with a short knife, and letting the poison on the blade do all the work. No special powers or complicated martial arts necessary.
  • Knife Nut: He inoculates poison with slashes of a folding, hooked knife.
  • Poisoned Weapons: His modus operandi to battle monsters. The poison is actually potent enough to drop them.
  • Screw This, I'm Outta Here!: Gives a very subdued one when the surface team observes a giant energy beam from Child Emperor emerge from the ground, send several buildings in the air, and continues up into the sky. He simply glances at his short knife, and wonders why he should stick around.
  • Skeleton Motif: Wears an undershirt visibly covered in numerous skulls to signify how deadly he is.

??. Allback-Man

Voiced by: Hiromichi Tezuka (Japanese), Bill Rogers (English)
  • Bring My Brown Pants: Happens in a confrontation with the Sea King. Then again, it's hard not to with an enemy like Sea King.
  • Cowardly Lion: He initially fled during the Sea King attack, but when Sea King broke into the shelter, he stood up and fought despite his fear.

??. Swim

Voiced by: Uki Satake (Japanese), Brianna Knickerbocker (English)
Teenage girl hero who appears in the 5th OVA episode. Is the lowest ranked hero of them all. She was initially thinking about quitting being a hero and had gotten on the same train as Genos and Blizzard to visit the seaside and clear her head. Working alongside Blizzard and Genos (especially the latter) inspired her to continue being a hero, especially after Blizzard's implied invitation for her to join the Blizzard Group if she makes it to B-Class.
  • All There in the Manual: Her name is never said in the OVA, but it is revealed in an art book.
  • Badass Normal: She is a member of the Hero Association, even if she is at the bottom. We know how heroes are evaluated. Even if she got perfect essay scores (an impressive achievement itself), she still would have needed at least an average physical score. And the average for heroes is significantly higher than normal people.
  • Canon Immigrant: She first appears in the 5th OVA episode, but later has a cameo in manga, showing that she does exist in Murata's version of the story.
  • Morality Pet: Basically serves to allow Blizzard to be a Defrosting Ice Queen and Cool Big Sis in the OVA.
  • Prongs of Poseidon: Fights with trident when she is in her hero costume.
  • You Remind Me of X: Variant 1, her underdog status and resolve to never give up reminds Blizzard of herself (while at the same time giving Blizzard back some of her own resolve).

Organization Staff

The organization that oversees and manages the individuals that want to call themselves heroes and serves as the governing body for them all. Their headquarters is located in A-City. Founded three years ago and is currently funded by donations from citizens, which they use to pay heroes depending on their rank and performance.



Voiced by: Nobuo Tobita (Japanese), Kirk Thornton(English) Daniel Lacy (Latin American Spanish)

The Minister Officer of Justice for the Hero Association.

  • Enemy Mine: He proposes one with all the super villains for the upcoming "God Level Class threat prophecy", but is stopped when Garou shows up and beats everyone up.
  • Oh, Crap!: Definitely suffered one of these (among other psychological breakdowns at the time) when The Hero Killer first introduced himself by single handedly defeating an army of assembled rogues and felons coupled with three top tier heroes.
  • Only Sane Man: He gets annoyed that the Hero Organization spent two hours debating on what Saitama and Genos' Hero names should be and only spent 15 minutes on the countermeasures on taking down Garou.
  • Reasonable Authority Figure: So far one of the only few people in the upper establishment with any real sense, be it common or otherwise.



A greedy, portly looking association branch director who turns a profit by selling potentially dangerous monsters.

  • Blatant Lies: Made up a cover story about the scales of a Mysterious Being he wanted captured being the source of a miracle element housing vast medical properties, when in reality it was just a means to withhold his shady dealings concerning the creature's value on the black market.
  • Fall Guy: Was this for Metal Knight/Professor Bofoy who was the real mastermind behind the underground monster trade said director was a part of.
  • Greed: His defining quality in the extra story; he was even willing to cast aside people's lives in order to hide the truth because of it.
  • Guilt by Association: Played this against an office clerk who opted to alert the association of the threat his employer's meal ticket now posed, partly because doing so would implicate the director for his illicit conduct.
  • Laser-Guided Karma: Eventually laid off by his puppet master after the whole scaledon debacle, at least until such time as he decides to reinstate him.
  • Promoted to Scapegoat: What happened to him at the end of the Special Chapter.
  • Suit with Vested Interests: Tried to make a mint off selling a recently captured monster only to cover up the true danger it represented after its escape by hiring a rag-tag group of heroes (plus Saitama) to recapture it.



Mccoy is a muscular man with glasses and an eyepatch on his right eye. His hair is combed upwards and he dresses in a formal business suit.

  • Big "WHAT?!": Given when a mysterious cop actually a disguised Saitama hands the police a win over the heroes on live television.
  • Break the Haughty: He tries to humiliate the Z-City police by getting the news crew to broadcast the heroes defeating the monster but Saitama, dressed as a police officer, already defeated the monster thus making the heroes who came to save them unnecessary.
  • Canon Immigrant: He first appeared in a bonus chapter of the Murata remake and didn't appear in the original webcomic until Chapter 107.
  • Hazy Feel Turn: Chapter 110 of the webcomic reveals he left the Hero Association and joined the Neo Heroes. It's unknown if he left because of Defector from Decadence or just him being an Opportunistic Bastard.
  • Jerkass: Refused to dispatch heroes to protect the police station during a monster attack until the chief swallowed his pride and begged him.
  • Jerkass Has a Point: While not at all a likeable person, in the webcomic he makes a valid accusation about those running the show being a herd of idiots. Given how many of them are somewhat like him, either greedy, stupid, incompetent or somewhat corrupt, it's a valid point.
  • Opportunistic Bastard: Shows traits of this in spades, both in the main and side stories.
  • Slime Ball: The way he wants to give the Hero Association and its glory-seeking soldiers unmitigated impunity to act by dragging the pride of the police through the mud and then turning it into a publicized media stunt of an over-glorified newbie crushing on live television makes him this.



A pudgy, unattractive Corporate officer working for the Association. Loves to embellish how big a deal he is in the hero organization to hot hero-loving fans.

  • Boisterous Weakling: Says he's a front line fighter putting his life on the line for the job, an obvious falsehood.
  • Hoist by His Own Petard: He brags to a pair of pretty women about how he's a front line fighter. The Hero Hunter happens to overhear this.
  • Sleazy Politician: To a lesser degree but apparent all the same, as he tried using his station to get a kiss from two of Amai Mask's fans.
  • Spot the Imposter: Got a couple of groupies believing he was some bigshot soldier in his business, but Garou didn't believe it one bit.

  • Badass Normal: He's a failed hero, but he's still strong enough to carry multiple people at once, with reflexes quick enough to react while moving at high speed.
  • Eye Beams: His cybernetic eye can shoot lasers, though it's very weak.
  • Major Injury Underreaction: Barely gets phased by the loss of a hand.
  • Mission Control: He's in charge of the strategy and operations for Waganma's rescue mission, and manages the support team.
