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.

S-Class heroes are rightfully considered the Hero Association's aces, yet they are also a terribly quirky and unruly bunch. Most of them are aloof to some degree and display a highly varying degree of zealousness to their work, as they possess motivations far removed from the material goals of the lower ranked heroes.

     1. BLAST 

BLAST

https://static.tvtropes.org/pmwiki/pub/images/blast_6.png

BLAST is the highest ranked S-Class Hero, but he's yet to be seen in the story. He's a mysterious figure that is never present for Hero Meetings but is still universally respected by others in the Hero Association. Some have said he is either too busy or just too shy to appear in front of people.


  • Foil: Seems to be deliberately set up as one for Saitama, due to the similarity of their hero costumes as well as the fact that he sees super-heroics as a hobby. Unlike Saitama, however, he has a regular day job (at least, back when Tornado was still young) and, most importantly, isn't bald.
  • The Ghost: Has been mentioned by the characters, but has yet to appear, outside of flashbacks. In the webcomic, he shows up in flashback during the Psychic Sisters arc, while in the manga, there's a picture of him in the Hero Hunt arc when the heroes who could defeat Elder Centipede are shown.
  • Heroism Won't Pay the Bills: As we see in Tornado's flashback, Blast was a hero 18 years ago, 15 years before the Hero Association was founded. As such, he described his hero work then as more of a hobby, and clarified that he had a proper job too.
  • Lampshade Hanging: The fact that nobody, not even the Hero Association, knows much about him is repeatedly and mercilessly joked about — apparently, he's just shy, really fussy, and has a thing about his privacy. Tornado's thoughts after her flashback now puts doubts about the latter ever being the case, as she is waiting for him to come back.
  • Minor Major Character: The highest ranking S-Class Hero... who has never made an appearance in the series.
  • Shrouded in Myth: The lack of any hard facts about him means that rumors surround him. Some examples are: that he's stronger than all the other S-Class heroes combined, that he can shoot beams out of his eyes, or that he has psychic power and billions of robotic forces.
  • World's Strongest Man: The number 1 hero in the world. How strong he’s supposed to be is unclear, as King is usually described as being "the strongest man" due to people mistaking Saitama's strength for his. In the manga's Hero Hunt arc, the Monster Association considers Blast one of only four heroes able to confront Elder Centipede head on, alongside King, Metal Knight and Tornado, as he grievously wounded Elder Centipede in an earlier fight two years before but was unable to capture him. Blast's actual strength remains unclear, though, as there are no details on what happened in the fight, or what stopped him from catching Elder Centipede.

    2. "Tornado of Terror" / Tornado 

Tornado

Voiced by: Aoi Yuki (Japanese), Marieve Herington (English), Azul Valadez (Latin American Spanish)

Debut: Chapter 32 (Webcomic), A New Wind Blows (Manga), Episode 6 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/tatsumaki_anime.png

Tornado, better known as Tornado of Terror, is an insanely powerful Esper who can freely manipulate matter with her mind. As the strongest Hero to regularly fulfill her duties, she is the Hero Association's trump card. Tornado has a younger sister, Blizzard, who is the highest ranking B-Class hero. She is generally abrasive and condescending to everyone she talks to, particularly to lower-ranked heroes like Saitama. Tornado is known to be extremely childish in both appearance and attitude, making other heroes either dislike her or ignore her altogether.


  • A Day in the Limelight: Gets the spotlight in one of Volume 10's bonus chapters, "Tornado's Day Off".
  • Art Shift:
    • Like Saitama, her look in the manga switches between having as much detail as the rest of the cast, and being a doodle more closely resembling her look in ONE's webcomic.
    • She also switches in the anime — which is particularly funny given the contrast between the anime's detailed drawings and ONE's webcomic drawings.
  • Attention Whore: She has some elements of this, getting quite annoyed over being ignored by Saitama and Genos.
  • Aw, Look! They Really Do Love Each Other: She may be bad at showing it, thanks to a rather dark past, but she genuinely loves her sister and will do anything to aid her ascent through the ranks of the Hero Association.
  • Badass Adorable: Looks like a child, and holds the number 2 spot for the entire Hero Association.
  • Berserk Button: People assuming she’s a child based on her looks and demeanor, or referring to her with derogatory terms for young people, like "brat" or "missy." She hit Genos so hard and fast after he called her a brat that he automatically corrected himself when he was about to call her a brat again, even though she wasn't anywhere near him.
  • Beware the Cute Ones: She may look adorable, but she's one of the most powerful psychics in the world. She isn't ranked as the second-strongest hero in the world for nothing.
  • Big Sister Instinct: You should NEVER mess with her sister Blizzard. When Garou said he killed Blizzard, let's just say she got incredibly pissed. However, her protecting Blizzard since she was little contributed to and potentially caused her sister's problems.
  • Blood Knight: As shown in the bonus chapter "Tornado's Day Off". When she gets a day off from fighting powerful monsters, she quickly gets bored and actually starts looking for monsters to kill. Turns out she enjoys doing it a lot more than she appears, as she almost goes nuts when she keeps finding monsters already slaughtered by Saitama until she finally manages to nail a small-fry monster to sate her boredom.
  • Born Winner: This is basically the reason she's S-Class Hero Rank 2 — she was BORN with the level of power she has.
  • Bratty Half-Pint: Her personality is straight-up obnoxious.
  • Cain and Abel: Cain to Blizzard's Abel.
  • Can't Hold Her Liquor: In the sixth OVA, she acknowledges that she's kind of a lightweight and knows when she's had enough, but ends up drinking more than she should after Saitama mistakes her for being underage. This results in her stabbing Zombieman.
  • Control Freak: What she is to Blizzard. When it's clear Blizzard is outmatched by her, Tornado decides she's going to force Blizzard to retire and that she'll make the decisions for the both of them. Luckily Blizzard gets her to relent...only for Tornado to say she's going to permanently bench her underlings as she believes they make Blizzard weak.
  • Cool Big Sis: Averted; Tornado likes to THINK she's this — clearly she HAD to be if Blizzard played with her all the time, right? Wrong, it was because the kids in their neighborhood were so terrified of Tornado that it led to Blizzard being isolated from everyone. In fact, her protective nature over her sister led to Blizzard resenting her.
  • Curtains Match the Window: Green hair and eyes.
  • Cute and Psycho: When she REALLY loses it, anyone who's a target of her wrath has good reason to be afraid.
  • Dark and Troubled Past: Revealed to have been taken away from her family as a child by scientists interested in studying and strengthening her powers. She was kept locked up when she wouldn't use them, and would beg for her little sister. It's quite obvious it's the reason she believes she only needs herself and why she's so fixated on trying to isolate Blizzard from her subordinates. It's also the reason why she's so immature; she never had a chance to interact with people and grow up in a healthy way.
  • Death from Above: How she easily defeats the Ancient Lizard King. When he told her that nothing short of a meteor could hope to kill him, she responds by dragging a meteor from space and slamming it onto him. All that's left of the Ancient Lizard King is a molten skeleton at the bottom of a giant crater.
  • Destructive Saviour: Tornado doesn’t know how to hold back, nor does she want to. Her attacks against Monsters and anything that faces her way are of immense proportions and cause collateral damage that she doesn't care about. She ignores warnings from her colleagues and staff at the Hero Association. It has reached the point where Tornado has simply been doing whatever she wants, like pursuing personal vendettas, and the Hero Association is seriously considering expelling Tornado and labeling her as a threat that needs to be taken out.
  • Disproportionate Retribution: She has a REALLY bad habit of doing this to anyone who pisses her off. Gets doubly bad if it involves Blizzard.
  • Early-Bird Cameo: In the anime, she gets an early appearance where she gets annoyed at the Hero Association admin with the stubble for not sending her to do the Z-City investigation in place of Golden Ball and Spring Moustache. She also gets an "I told you so" moment when she hears that the investigation went awry due to the seaweed monster.
  • Establishing Character Moment: In the anime, immediately after being deployed to deal with what can best be described as a talking Godzilla knockoff, Blizzard gets a call from her superiors telling her to come back and gets into an argument with them. When the monster tries to give its Motive Rant, she yells at it to shut up until she gets off the phone. Then when it tells her nothing short of a meteor can kill it, she calmly says she'll just have to get one of those, uses her powers to just nonchalantly pull one out of space and literally liquefies the monster with it. That's Tornado in a nutshell: Cool and composed one moment, shouting at someone like a bratty kid half her age the next, and so ludicrously powerful she can always get away with it.
  • Everything's Better with Spinning: She seems to be very fond of this trope.
  • Family Theme Naming: Blizzard and Tornado are named after windstorms.
  • Fatal Flaw: Pride. She is a really firm believer of the class system within the Hero Organization and believes skill should match as such. Her pride also makes her think that she's a really good sister to Blizzard, when in fact a lot of her actions have damaged their relationship.
  • Flight: With her psychic aura, she can fly. She seems to prefer hovering over walking as well. Not to mention that she can also launch herself at high speeds that form thick trails in the sky whenever she goes.
  • The Glorious War of Sisterly Rivalry: With Blizzard, who she thinks is wasting her time and talent in Class B and should ditch those losers and become the hero she was destined to be. It’s presumably meant as a compliment, but this is Tornado we're talking about.
  • Going Commando: Many shots in Murata's re-draws and the anime seem to imply she wears nothing BUT her dress. However, in the original webcomic, King claimed to have seen her panties once, she has several panty shots later on, and Murata has stated she does in fact wear underwear.
  • Good Is Not Nice: The only reason she's not more of an anti-hero is that, despite the way she acts, she does seem to genuinely want to help people and she does love her sister.
  • Hair-Trigger Temper: One minute she'll berate a hero for being useless but in the next chew you out for insulting the same hero, if you're lucky.
  • Hey, You!: She refuses to address anyone except her little sister Blizzard by their proper name, only by their hero names at best and a whole slew of insults at worst. This makes it all the more surprising when she asks Saitama for his name after their fight when she called him by many, many variations of "baldy" beforehand.
  • Hidden Depths:
    • In spite of her multiple tantrums and abrasive nature, Blizzard never raises her hand against her fellow heroes nor uses her powers against them even when she's easily irritated. Even with a mouth as big as hers, this shows that she does have a fundamental code that she follows.
    • Even with the selfish overtones that she raises whenever Blizzard comes into consideration, it's shown that she does want her sister to rise above the stopgap that she put on herself. Belittling as she is, Tornado is more than aware of what Blizzard is capable of, and wants her to pursue it instead of pussyfooting on B-rank.
  • Hypocrite: She gets mad when people call her a brat, yet her attitude is exactly like that of a spoiled child.
  • I Will Find You: The reason why she joined the Hero Association: she's looking for Blast, who saved her life 18 years ago.
  • Jerkass: Her attitude toward the people around her leaves a lot to be desired. Case in point, when she sees Saitama after the alien invasion, she goes and starts yelling at him because he's a B-Class Hero (although she may have just been annoyed about being ignored). When Genos objects, she uses her powers to fling him into a rock, and she would have attacked Saitama if Bang hadn't gotten her to back off.
  • Jerkass Has a Point: Despite being fairly hypocritical herself, her calling out Amai Mask on being a smug hypocrite who thinks that the S-Class heroes take their responsibilities too cavalierly and should strive to be paragons while he spends most of his time being a teen idol and using his popularity amongst the mass media to manipulate the Association is absolutely correct. Of course, Amai Mask completely ignores her.
  • Jerk with a Heart of Gold: Despite how abrasive and antagonistic she is, she's still a superhero who will protect innocent civilians if they are in danger. Also, like Metal Bat (albeit to a much smaller extent), she does have a soft spot for her little sister.
  • Little Big Sister: Big sister of Blizzard, and much shorter.
  • Logical Weakness: Head injuries can cripple her psychic powers.
  • Love Makes You Crazy: While no one doubts that she genuinely loves Blizzard and wishes the best for her, Tornado's behavior in expressing it is completely out of control and even downright disturbing at times.
  • Magic Skirt: That dress of hers floats around but always manages to stay just shy of her waist.
  • Meaningful Name: In the original Japanese manga, her name is not written out with kanji, implying that Tatsumaki (meaning "Tornado") is actually her real name. She just added "of Terror" to it.
  • Mind over Matter: Tornado is shown to be the most powerful esper in the series. She can manipulate objects many times her size and from great distances. She once called down a meteor from space, and sent an entire volley of huge bullets back up to the alien ship that shot them. She also uses her psychokinesis to float and fly.
  • Ms. Fanservice: Lots of shots of her butt and also some shots of her legs. Her navel is also shown in her pajamas. This is only when she's detailed however.
  • Names to Run Away from Really Fast: Second most powerful hero in the world, sans Saitama, and essentially the Association's trump card.
  • The Napoleon: She HATES to be reminded of her short stature and to be mistaken for a kid.
  • Never Be Hurt Again: The reason she hates the idea of friendship. She was sold by her adopted parents at the age of seven to scientists who experimented on her and shut her off from all social contact, only to abandon her to her death when a monster rampaged despite her pleas for help. Blast saved her, but told her to never expect anyone else to come save her again should she be in trouble. Her childhood has left her with major abandonment issues that she projects onto Blizzard by scaring away anyone that might hurt her little sister.
  • No-Holds-Barred Beatdown: When she's called upon to make sure a monster stays dead, she doesn't mess around (though ironically, in her first appearance in the reboot, she only severely wounded the robot Blizzard and her subordinates were fighting and it got back up as soon as she left. It was finished off by a passing Saitama).
  • No Kill Like Overkill: She alone can handle enemies that can overpower the rest of the S-Class heroes.
    • She sent Genos flying and flattened him on a wall without lifting a single finger.
    • Singlehandedly wrecks an alien spaceship without exerting her powers. Then again Saitama was fighting Boros above the ship and there were numerous times that the ship was hit by their attacks, especially by Saitama landing on it after jumping back from the moon.
    • Calls down a meteor on a Godzilla Expy in the anime.
  • No-Sell: Just like Saitama, whose toughness allowed him to shrug off Geryuganshoop's telekinesis-induced increase in gravity, Tornado does the same to Gyoro Gyoro's attempt at the same trick with her greater psychic power.
  • No Social Skills: She seems incapable of talking to someone else without being abrasive and shoving in as many insults as possible.
  • Older Than She Looks: Despite looking like a young teenager at best, she's actually 28. She even looks younger than her younger sister, Blizzard.
  • Person of Mass Destruction: Her telekinesis makes her immensely powerful. She was able to deal with a Godzilla-like monster by dropping a meteor on it.
  • Psychic Powers: She is an immensely powerful Esper capable of obliterating most threats single-handedly.
  • Psychopathic Womanchild: She acts like this occasionally, especially when she wanted to kill a still alive Psykos. It's later revealed that she was experimented on as a child and denied any contact with her family or the outside world. It's clearly left her with a bit of PTSD and emotionally underdeveloped.
  • Shana Clone: She's basically Louise de la Valliere if she was a psychic.
  • She's Got Legs: Her legs get a lot of focus despite (or perhaps even because of) her petite frame. This is further emphasized by her dress, which is cut to reveal the most amount of leg possible without exposing her underwear (if she wears any). She is also purposely drawn as more shapely than what a child her size should be, further driving the point that she's Older Than She Looks.
  • Smug Super: On account of winning the Super Power Lottery. Against major threats she's often the only hero who's any use at all, and she's not shy about reminding everyone of this fact. Even the Monster Association respects her power, listing her as one of the few who can take on their heavy-hitters (who are Dragon-level threats) and come out the winner.
  • The Smurfette Principle: The only woman among the S-Class heroes. And there was a point where she and her sister were the only recurring female characters, period.
  • Steven Ulysses Perhero: Her given name means Tornado, and she fights using telekinesis. Guess what she usually does with it?
  • Super Power Lottery: With her Psychic Powers, she's on a whole different level compared to her fellow S-Class (barring maybe Blast), as seen during the Monster Association arc, where she easily handles the top monsters of the association which had all quickly defeated other S-Class heroes. She's also considered the Hero Association's trump card.
  • Tiny Tyrannical Girl: She's very short, short-tempered, abrasive and incredibly bossy.
  • Token Mini-Moe: The youngest-looking member of the S-Class heroes besides Child Emperor, who actually is 10.
  • Underestimating Badassery: Assumed Saitama was a small fry just clinging to Blizzard for notoriety. Then Saitama stops her from murdering Psykos and when she blasts him telekenetically at full force, he shows little to no discomfort forcing Tornado to exclaim "He's not just some small fry". She also tries to mess him up internally and the most she can do is make his muscles shake a little.
  • Worf Had the Flu:
    • After getting injured by a combined attack from all the top monsters in the Monster Association she doesn't last very long against Garou, and passes out from over-exertion before he can even attack her. She claims that if she were in fighting form, he would have only taken her five seconds. It's hard to know if this is true. On one hand, she crushed most of the top Monster Association members by herself (who were individually easily in the Demon to Dragon class). On the other hand, considering how thoroughly Garou decimated the other S-Class Heroes and how long he lasted against Saitama, this may not be true.
    • During her fight against Saitama during Chapters 102 through 105, she avoids using her full power against him because it reopened possibly fatal wounds she suffered from her over-exertion during the raid. All her attacks throughout the arc were a No-Sell on Saitama, but for a brief moment she considered going all out on him despite the risk of death, indicating she had more powerful attacks that weren't utilized. Even after her last attempt to subdue him failed, when all was said and done she still boasted she could take him in five seconds in tip-top shape.
  • World's Strongest Woman: She's the single most powerful female character shown in the series (not that there are many) and, while still nowhere near as strong as Saitama, is often the only one among the cast who can actually hope to defeat or at least significantly injure the Arc Villain. Even among her fellow S-Class heroes she's regarded with respect and fear.
  • Workaholic: In Volume 10's bonus chapter, it is shown that the Hero Association usually calls on her to deal with high level threats, and while she may complain about it, she does her job anyway. She gets bored when she gets some time off, having nothing to do, so she goes looking for monsters to fight.
  • Worthy Opponent: Very, very, very grudgingly views Saitama as this. When she fights him, she realizes he's no "small fry" and that most of her attacks won't do anything to him. After the fight, she asks him for his name and admits he's "kinda strong." When one considers she calls her fellow S-Class heroes to be useless and Dragon level monsters small fry, it speaks volumes about being called "kinda strong." Of course, she won't admit it to herself and claims she could beat Saitama in five seconds if she was healthy.
  • Yandere: For Blizzard; she HATES that Blizzard has amassed so many followers who look up to her and is determined to have Blizzard sever ties with them. When she refuses, Tornado decides she's going to make the entire Blizzard Group retire by force. Saitama gets disgusted with Tornado's attitude and directly confronts her, much to Blizzard's shock.
  • You Gotta Have Blue Hair: Has green hair.

    3. "Silver Fang" / Bang 

Bang

Voiced by: Kazuhiro Yamaji (Japanese), John DeMita (English, credited as Will Barrett), Pedro D'Aguillon Jr. (Latin American Spanish)

Debut: Chapter 20 (Webcomic), Chapter 21 (Manga), Episode 7 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/silver_fang_anime.png

"Silver Fang" Bang is a martial artist, and Master of the Fist of Flowing Water, Crushed Rock. A kind old man but a stern dojo master, Bang is the first S-Class Hero to witness Saitama's power and has become an acquaintance of his. His former disciple, Garou, decimated Bang's dojo and then took to Hero hunting, prompting Bang to chase after Garou to stop him once and for all.


  • A Day in the Limelight: The fourth OVA, focusing on his initial attempts to get Saitama to join his dojo.
  • Back-to-Back Badasses: When he teams up with his brother, Bomb.
  • Badass Normal: His fellow S-Rank heroes are psychics and cyborgs and the things he fights are monsters, but there's nothing that indicates that he has anything other than his martial arts skill.
  • Bare-Fisted Monk: Uses nothing but his martial arts in fighting.
  • Charles Atlas Superpower: He's pretty damn strong thanks to his mastery of the Fist of Flowing Water, Crushed Rock style. In terms of raw physical power, he's behind only Blackluster among the S-Class heroes.
  • Cool Old Guy: He's 81-years-old, and he's still in the hero business, still can kick your ass, and is still one of the leading martial arts figures in the world.
  • Covered with Scars: Under that shirt of his lies a body that's seen the wear and tear of a martial artist superhero. However, his only complaint about his body is about his hips and back, due to old age.
  • Fantastic Fighting Style: The Fist of Flowing Water, Crushed Rock.
  • Friendly Rival: With Atomic Samurai.
  • Hidden Depths: In his OVA he comes up with an Absurdly High-Stakes Game of Janken-Po that breaks through Saitama's normally dispassionate exterior and actually gives him an appreciated challenge.
  • Intergenerational Friendship: He's 81-years-old, but has good banter with 37-year-old Atomic Samurai. Their relationship has yet to be fully explained, but they're both heroes who made it to the S-Rank with natural ability and traditional combat skills instead of super powers, and are both known to take on pupils in their respective styles, so they may respect each other as martial artists.
  • Let's Get Dangerous!: He doesn't like getting serious because of his old age, but when he does, watch out. He'll rip through even Dragon level monsters like wet toilet paper.
  • Made of Iron: Remember that attack by Melzargard that tore off Iaian's left arm? Bang got hit directly with that and was smashed through rubble and a few buildings for good measure, and all it did was tear off his shirt. Cue Melzalgald's Oh, Crap! moment.
  • The Mentor:
    • Considered on taking Saitama and Genos as his disciples. They both decline. Genos states that he has no need for self-defense techniques and only wants unparalleled destructive power. Saitama declines because he's simply not interested and he doesn't need to resort to martial arts when he has such an overwhelming stat advantage in every area.
    • He's also the former master of one of the most powerful enemies in the series, "Hero Hunter" Garou.
  • Nice Guy: One of the kinder heroes in the series, Bang was one of the only S-Class to show up for the meteorite meeting even with the knowledge that he could do nothing to help. He is almost always polite and treats Saitama with a lot of respect.
  • Oh, Crap!: Played for Laughs when playing a game of hammer rock-paper-scissors with Saitama. Bang's superior dexterity lets him dominate both Saitama and Genos. But once Saitama gets fed up and starts using his real strength, Bang immediately gets the hell out of dodge as the ground where he sat was utterly pulverized.
  • Old Master: Bang spends much of his time not fighting monsters or villains, but finding disciples to teach. He has a couple of students in the Hero Association and a former student who's a villain.
  • Old Superhero: He's 81-years-old, making him the oldest active hero. It can be said that he's been doing the hero business since most, if not all, of the other heroes were born and definitely way before the Hero Association was founded. When he takes what looks like a fatal hit from Melzargard into building rubble, he walks it off with a comment about getting too old to be a superhero.
  • A Pupil of Mine, Until He Turned to Evil: "Hero Hunter" Garou was once Bang's best disciple.
  • Reality Ensues: He might be one of the two best martial artists out there, but he's still an old man, which means he can't fight seriously for too long. Also, because he's a martial artist first and foremost even with his skills and physical power, he's less effective against giant monsters and massive obstacles like meteorites.
  • Reasonable Authority Figure: After he witnesses Saitama's power, he treats him as one of his equals.
  • Retired Badass: After the events with Garou, Bang blames himself for what happened. Along with age slowing him down, he decides to retire from being a hero.
  • Silver Fox: He's absurdly fit and muscular for a man his age. Just look at him.
  • Strong and Skilled: He's got some insane Charles Atlas Superpower alongside complete mastery over his own martial arts style.
  • Supernatural Martial Arts: A master of Fist of Flowing Water, Crushed Rock. Although a fictional style, its philosophy of repelling, parrying or using the force of enemies' attacks against them are pretty standard in the real world of martial arts., specifically paralleling Tai-Chi. What makes this style extraordinary is that it enables a man in his eighties to not only keep up with but even exceed and overpower other S-Rank heroes, Dragon Rank monsters, and aliens with apparently nothing more than training and technique.
  • World's Best Warrior: One of the two greatest martial artists in the world, alongside his older brother Bomb.

    4. "Atomic Samurai" / Kamikaze 

Kamikaze

Voiced by: Kenjiro Tsuda (Japanese), Kyle Hebert (English), Antonio Gálvez (Latin American Spanish)

Debut: Chapter 32 (Webcomic), Chapter 29 (Manga), Episode 10 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/atomic_samurai_anime.png

Real name Kamikaze, "Atomic Samurai" is a practitioner of Iaijitsu with exceptional speed and strength. With a slash of his sword, Atomic Samurai cuts down his opponents at the atomic level and typically shreds them to pieces. He maintains a friendly rivalry with Bang and his three students are among the top A-Class Heroes.


  • Cool Old Guy: He's one of the oldest S-Class heroes. He's actually only 37, so he's only comparatively old.
  • Crippling Overspecialization: He's a master swordsman, perhaps the best in the world. Problem is, that's all he's good at. Take away his sword and there's not much he can do. Garou calls him out on this, saying that even if he can't fight properly without a sword, it's still no good excuse to just stand there without helping in some way.
  • Dramatic Irony: Outwardly tells Saitama that he only acknowledges the strong, and to get to S-Class if he wants to be greeted properly. He said this to a guy who can kill almost anything with a single punch.
  • Everything's Better with Samurai: He dresses like a samurai.
  • Friendly Rival: To Bang. It's hard to say what they won't compete over. During the S-Class hero meeting, he wonders if Bang will teach Saitama and Genos martial arts, thinking that they will make decent rivals for his own disciples.
  • Horrible Judge of Character: He is highly lacking in perception, and often judges people based on reputation alone rather than their actions.
  • Hot-Blooded: Normally he’s fairly calm, but once he is fighting...
  • Idiot Ball: To test King's strength, he asks him to use his sword to cut an apple. King is unable to even pull the sword out of the sheath and eventually gives up and walks away. Iaian, Okamaitachi, and Bushidrill are understandably bewildered, but Atomic Samurai assumes that King was able to cut the apple at the cellular level in such a way that it didn’t even know it had been cut. He concludes that King is clearly leagues above him in swordsmanship.
  • Implausible Fencing Powers: Atomic Samurai only needs one visible swing of his katana to cut a horde of monsters into shreds, with hundreds of slashes seen coming from all directions.
  • Jerk with a Heart of Gold: Boisterous but good-natured. His comment to Saitama about him needing to be S-Class in order for Atomic Samurai to shake his hand comes across less as a dismissal of his abilities, and more as a friendly challenge and attempt at motivation. He also cares a lot about his disciples, and is absolutely furious when Garou goes to attack them while they're unconscious.
  • Katanas Are Just Better: He carries two katana. His primary one has a black hilt with a cross-guard that resembles the Rutherford atom model.
  • Master Swordsman: A formidable swordsman. His sword attacks are so fast and strong that the enemies are slashed into many pieces in an instant without even being able to react. After the fight with Melzargard, he developed an attack that concentrates his cutting power so much he can completely annihilate pieces of Black Sperm without leaving any cells surviving to split and grow into new ones.
  • The Mentor: He has 3 disciples who are the top 3 A-Class heroes, after Amai Mask.
  • Non-Indicative Name: Atomic Samurai is not a samurai powered by atomic energy nor is he a samurai who uses atomic energy in any way. He may be able to literally slash his targets into atoms, but that's never been explicitly stated.
  • Oral Fixation: He's always seen, chewing on a barbecue stick. It also becomes a Lethal Joke Item in his hands, as he can casually weaponize it to slash through weak monsters.
  • Samurai: He's got the look down.

    5. Child Emperor 

Child Emperor

Voiced by: Minami Takayama (Japanese), Sara Cravens (English), Darhey Fernándezz (Latin American Spanish)

Debut: Chapter 32 (Webcomic), Chapter 29 (Manga), Episode 10 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/child_emperor_anime.png

A 10-year old genius inventor, Child Emperor is the brains of the Hero Association, and works to create gadgets that will help fight Monsters. He typically carries a number of deadly school-themed weapons in his backpack to battle.


  • Actor Allusion: In OVA 6, Child Emperor takes up the role of detective and starts acting like Detective Conan. He's voiced by Minami Takayama, who is also the voice actress of Conan Edogawa.
  • Actually a Doombot: He controls Dogman, a robot disguised as a hero, to fight monsters in his place and gather information.
  • Badass Bookworm: Though his usual method of fighting is to have the machines in his backpack handle everything, if "Okame-chan", the device he built to measure physical strength, is to be believed, he's about as strong as a typical A-Class hero on his own strength. He even mentioned that he once fought and beat Atomic Samurai's three disciples.
  • Bag of Holding: His school backpack holds all his gadgetry, as well as his school items. Some of his gadgets are several times bigger than he is.
  • Beehive Barrier: His umbrella casts a round one to protect the person holding it.
  • Broken Pedestal: After the events of the Garou arc with both Blast and Metal Knight refusing to aid in battle, he decides that the "adults are useless" and begins working on surpassing them all himself.
  • Break the Cutie: He's a genuinely sweet kid and a true hero, but the events of the Garou arc leave him thoroughly untrusting of others. The manga expands on this by adding in several conversations between him and his former mentor Metal Knight, where the latter constantly advises him that he can only rely on himself and refuses to do the heroic thing when he thinks it's a waste of resources.
    • Happens to him while rescuing the child hostage from the Monster Association. He breaks down in tears when he gets cornered by Phoenix Man Reincarnated, and subsequently needs to pull out his trump card, as he perceives the fact he had to use his ultimate weapon on a monster that was essentially middle management as proof of his weakness.
  • Child Prodigy: A ten-year-old inventor hero. He possesses an extreme intellect, far above that of average adult humans. He can create advanced technology, one of which is a four-legged contraption that sprouts from his backpack.
  • Combining Mecha: Three of his Underdog robots can combine into the more powerful Mad Dog: Underdog Cerberus.
  • Crazy-Prepared: Thanks to his numerous inventions, all of which he keeps in his backpack, he's able to handle a wide range of scenarios and multiple types of enemies. He's got drones and weapons for just about anything he's thought of, be it a small drone for ambushes, flammable liquid against slime monsters, electric stun guns for evil robots, a deployable lollipop wrapping paper for thrusting attacks...
  • Defector from Decadence: After the events of the Monster Association, he finally left the Hero Association to join the Neo Heroes due to the former inability to change and take his suggestions seriously. However, he makes it clear he doesn't trust the Neo Heroes either.
  • Entertainingly Wrong: Built a mask-device for the purpose of analyzing power levels. When he uses it on Saitama and it can't give a proper reading, he assumes it's because Saitama is too weak for proper measurements. When he uses it on King and gets the same results, he assumes it's because King is too strong.
  • Humongous Mecha: His ultimate weapon, Brave Giant, is a giant robot suit capable of going up against Dragon-level threats, but it can only last a few minutes before the power supply runs out.
  • Innocent Innuendo: Apparently, in the original Japanese, his hero name has similar katakana to the word 'Virgin'. Considering he's ten...
  • Just a Kid: Knows exactly how to use this to his advantage. Many a monster has been fooled into coming close to him, thinking him to be a harmless child... Only to get a faceful of hi-tech guns and cutting blades.
  • Kamehame Hadoken: Can perform this in his Brave Giant mecha.
  • Kid Hero: He's the youngest of all the S-Classes, still young enough to go to school.
  • Kid Sidekick: In his C-Class days. He was actually Metal Knight's lab assistant for a while.
  • Laser Blade: Has one with the hilt in the shape of a clarinet.
  • Multi-Armed and Dangerous: His backpack also contains multiple robotic limbs that sport various bladed weaponry that allow him to directly fight monsters.
  • Pint-Sized Powerhouse: Don't let his size fool you. He's apparently twice as strong as a bear even without his gadgets, and he's apparently managed to beat Atomic Samurai's disciples in hand-to-hand combat before.
  • Shock and Awe: His Bug Net device consists of several misses that form an electrical net for the purpose of halting robotic enemies.
  • Shouldn't We Be in School Right Now?: Complains that he had to skip school to participate in a Hero Association meeting.
  • Spider Limbs: His backpack contains large spider-like limbs that Child Emperor can use for transportation and to fight. It is also strong enough to take a Demon-class opponent's attack.
  • The Strategist: He has an analytical mind, allowing him to plan ahead to ensure victory on the battlefield. He also searches for possible weaknesses of his enemies.
  • Sweet Tooth: He's sometimes seen with a lollipop. He later monologues this as "giving the brain some glucose" which, for his abilities, may actually be true.
  • Token Mini-Moe: The actual youngest member of the S-Class heroes.
  • Wake Up, Go to School, Save the World: He may be a hero, but he still has to go to school.
  • Where Does He Get All Those Wonderful Toys?: He invents and builds them himself of course, and his weapons are a definite notch above Homemade Inventions, being designed to look like an ordinary schoolboy's items but hiding sophisticated technology beneath.

    6. "Metal Knight" / Doctor Bofoi 

Doctor Bofoi

Voiced by: Tessho Genda (Japanese), Jamieson Price (under Taylor Henry) (English), Guillermo Rojas (Latin American Spanish)

Debut: Chapter 20 (Webcomic), Chapter 21 (Manga), Episode 7 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/metal_knight_anime.png

Dr. Bofoi, or "Metal Knight", is a mysterious scientist who controls a powerful ballistic robot with exceptional firepower. He is an aloof (and considered downright suspicious by Drive Knight) Hero who seldom meets and coordinates with his colleagues, and is only interested in collecting pieces of technology. He eventually becomes interested in Saitama.


  • Arms Dealer: With the rise of the monster threat, Dr. Bofoi sells his technology to many customers, be it weapons or bunkers or prisons to detain monsters. Saitama makes his products look ridiculous when he casually destroys them during a dispute with Tornado, causing Bofoi to antagonize him.
  • Destructive Savior: Metal Knight's usual MO is to use intense firepower to obliterate an opponent, as well as everything in the opponent's vicinity.
  • Even Evil Has Loved Ones: His "evil" is debatable, but he's certainly at best a nominal hero. Despite this, he still seems to care for his former protege Child Emperor, as he gives the boy some sincere recommendations and advice throughout several conversations between the two. Of course, because this is Metal Knight, such advice usually consists of pragmatic but Family Unfriendly Aesops such as "You can only trust yourself when it comes to justice" and "don't assist the other heroes with attacking the Monster Association if it'll get you killed."
  • For Science!: To get him to even appear to a fight, you have to promise him that he can take the monster/whatever back to his lab to study it.
  • Legitimate Businessmen's Social Club: Metal Knight runs an illicit trade for selling dangerous monsters and mysterious beings for profit on the black market. Often times he'll include some of the HA's more manipulable staff in on the take in order to make lots of money.
  • Macross Missile Massacre: His newly developed weapons are a bunch of missiles that he first field tests on the meteor falling to Z-City.
  • Mad Scientist: His "heroism" is rather ambiguous, as he only ever shows up to take samples for research or test out his new weapons.
  • Man Behind the Man: Seems to be the case with a lot of the handlers within the Hero Association, particularly either the more conniving and/or inept ones.
  • More Dakka: His modus operandi.
  • No Kill Like Overkill: His style is usually hitting an opponent with overwhelming destructive power so that he completely obliterates it. He'll probably hold back a bit if the opponent is something he wants to bring back to his lab.
  • Nominal Hero: He appears to have no interest in actually saving people or bringing justice, only fighting monsters to test weapons or study them. Private conversations with his former protege Child Emperor reveal that he does believe in a sort of justice and is fighting for it (and encourages Child Emperor to do the same), but it's so cold and pragmatic that it doesn't look heroic at all.
  • Older Than They Look: A variety. He is actually an old scientist. While he looks about his age, he's not exactly seen in public since he only shows up outside of his lair via remote-controlled robot.
  • Pragmatic Hero: In the manga, he figures out the Monster Association is trying to lure the Hero Association into a fight in order to eliminate them, and proposes they avoid this by blowing up the Monster Association's hideout with explosives, giving up on rescuing their hostage. He's turned down.
  • Reed Richards Is Useless: Averted, he's responsible for the sturdy bunker of the Hero Association, and his robots rebuilt A-City within days.
  • Refusal of the Call: Seriously, they literally call him up saying he should do SOMETHING, and he doesn't bother to even answer the phone (personally at least).
  • Remote Body: Unlike most heroes who use Powered Armor, such as Iron Man, Metal Knight does not actually wear his, instead sending it out as an unmanned drone. This allows him to accomplish dangerous missions with no real risk to himself.
  • Science Hero: He uses unmanned robot suits to battle monsters and builds bunker-like buildings that are pretty damn resistant to being blown up for the Hero Association.
  • Vast Bureaucracy: What he views the Hero Association's top brass as and hates them for, but has no trouble with it so long as he can manipulate this for his own benefit.
  • Weapon of Peace: Bofoi's main doctrine as a hero involves experimenting with incredibly dangerous armaments for the sake of world peace.
  • The Worf Barrage: Despite his reputation for overkill, he is yet to win a battle on-screen.

    7. King 

King

Voiced by: Hiroki Yasumoto (Japanese), Rich Brown (English), Jorge Palafox (Latin American Spanish)

Debut: Chapter 32 (Webcomic), Chapter 29 (Manga), Episode 10 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/opm_king_anime_8.png

The Hero named King is considered the world's strongest human whose powers are said to be comparable to Tornado. He's one of the most popular heroes, although no one is quite sure what his fighting style is. He and Saitama become friends and play video games together.


  • Badass Arm-Fold: Is often seen doing this on the battlefield, standing aloof and alone, although that is because he doesn't know what to do with his arms and has to stop himself shaking because he can't fight.
  • Badass on Paper: Parodied. Even though he's powerless, King can still intimidate the enemies just by glaring at them, forcing them to flee in terror.
  • Becoming the Mask:
    • Upon learning his secret, Saitama recommends that King become strong for real and actually earn his feared reputation.
    • As of Chapter 109 (Murata version), he actually does manage to start killing real monsters on his own in a way that fits his exaggerated reputation by merely staring it to death with a single glance. He wasn't even aware of what he was doing, though.
    • Subverted during the Monsters Association Arc. When asked to use a special attack to fight Black and Golden Sperm, he bluffs it by shouting some made up attack name, but the strength of the courage that was keeping him there instead of running away allowed him to tap into his true power and fire a Kamehame Hadouken said to rival Saitama's power, killing both the monsters... before it revealed that this was all King's imagination and he ran away.
    • He sincerely tries to find a way to do this afterwards, but sadly can't find a trainer who doesn't pre-emptively dismiss him as too strong to be taught anything.
  • Blatant Lies: He claims that he mistook a dating sim for an action game when Saitama catches him playing it, despite the box cover making that impossible.
  • Born Lucky: Played for laughs. Although he is rather pathetic, it still doesn't stop him from being S-Class through sheer coincidences and sometimes absolute pure luck, simply because he's always in the right place, at the right time, and usually does something completely mundane that helps the situation.
  • Bring My Brown Pants: Saitama points out he's widdled himself after they're attacked by a monster.
  • Brown Note: Whenever he appears on the battlefield or is confronted by a monster, a loud DOOM DOOM DOOM sound can be heard from King. This has been dubbed the "King Engine" and is usually enough to scare the unlucky monster shitless. This turns out to be King's own heart as he tries not to freak out.
  • Can't Stay Normal: This trope is hilariously played straight, subverted, and inverted in the span of a chapter. King knows that sooner or later his reputation won’t be enough to save him or others, so he tries to learn martial arts to become strong and is trying to play this trope straight. However, due to the exaggerated rumors of his superhuman feats, martial artists like Bang and Bomb believe that King is already strong enough as he is and that he’s either being humble or won’t learn anything from then. He is then sent to other martial artists, but they all refuse to teach him, since they don’t want to make him more abnormally strong, which ironically makes him remain just as weak and normal as he really is. As a result, the thought of dying while trying to fight a monster one-on-one becomes increasingly appealing to him.
  • Cassandra Truth: King tells everyone the truth on a fairly regular basis, that he's just a weak normal human, but nobody believes him (thinking of it as King being the Humble Hero), other than Saitama. He even tries telling martial artists like Bang and Bomb about it in hopes he'll genuinely get stronger, but he gets turned down every time since, because of the rumors surrounding him, they mistakenly believe that King is already powerful and his supposed humility means that he won't be able to properly learn anything from them. As a result, he eventually gives up and considers dying in a monster attack.
  • Chewbacca Defense: He talks his way out of a duel with Atomic Samurai with this — a whole lot of nonsense regarding the date, the phase of the moon, and the composition of atmosphere, all supposedly making it a bad time to duel.
  • Clark Kenting: Whenever King needs to go outside on errands in town, he just need to put on a cap and pull his hood on, nobody (as in "civilians" that is, other heroes can spot him just fine but keep it to themselves) can recognize him for five cents, until the cap and the hood comes off, then he gets swarmed by his awestruck fanbase in a moment's notice. It work on monsters as well, to great effect as the moment his "disguise" accidentally comes off, they collapse in self-induced heart-attacks the instance they realize "who" it is that's standing right in front of them.
  • Comically Invincible Hero: Parodied. He has such a fearsome reputation as the strongest man in the world that he effortlessly defeats enemies due to them running in fear as soon as he appears. Except it turns out he is a Fake Ultimate Hero with his reputable strength actually being a case of mistaken identity from Saitama.
  • Cowardly Lion: Although he confesses that he's always completely terrified of his opponents and considers himself a coward, he still manages to put up a strong front even against enemies that send other S-Rank heroes fleeing, despite having no powers at all.
  • Curb-Stomp Battle: He defeats 30 members of the Blizzard Group, including one who was a former professional gamer, all by himself in a video game contest.
  • Death Glare: Subverted. His face gives off this impression from other's perspective, but in reality it's actually how he looks when he's completely terrified. Yet it's so intimidating one shape shifting monster actually fell apart and died just from being on the receiving end.
    • If one looks closely at his famous "glare", you can see that his eyebrows are always in a slightly saddened expression. This serves as a subtle early indication that he's always concealing his pants-wetting terror behind his mask of intimidation.
  • Dirty Coward: He decided to run away from G4 despite its threat of executing innocent civilians if he wouldn't fight it. Although it's Justified that even if King goes to fight G4, it wouldn’t do any good since King would be instantly killed and G4 would just go execute civilians anyway. He seems to become braver later on when he temporarily draws the attention of enemies that bested other S-Class heroes, but still runs away when it's apparent that he's not much help beyond that.
  • The Dreaded: His reputation alone is enough to send powerful enemies running in fear.
  • Expy: As a Born Lucky, Cowardly Lion Fake Ultimate Hero who, despite being a normal human, is revered by the populace as the World's Strongest Man due to the actions of the real hero, he's like Mr. Satan, but nicer and without Glory Seeker tendencies.
  • Entertainingly Wrong: Anything that King does (or doesn't do) is immediately tied to his reputation of being such a badass that characters go out of their way to justify his actions as something only King would or could do. Of course, the audience knows that King is just a normal guy, so the justifications usually sound like Insane Troll Logic.
  • Face of a Thug: His stern, stoic face with those three long scars across his left eye screams "retired gangster/thug". Even his "terrified" faces can be mistaken for hostility. It's a good thing, too, since he can use it to scare his enemies.
  • Fake Ultimate Hero: King has basically the recognition Saitama should rightfully have if everyone grasped how powerful he was. Indeed, King is in reality a regular civilian who unwillingly gained the glory associated with Saitama's earlier heroic feats. He just doesn't have the heart to tell people they're wrong about him because it might upset the civilians, and so the tales of his 'deeds' keep piling higher and higher...
  • Foil: To Saitama, who he is the complete antithesis of. While Saitama is outrageously strong with no recognition, King is a totally ordinary guy who everyone thinks is an invulnerable superhero. Bonus points in that Saitama is directly responsible for King's current status and vice versa.
  • Godlike Gamer: While King is a complete fraud, having been confused for being a hero and "the world's strongest human" due to being in the wrong place at the wrong time multiple times, he is a wiz at video games. So far, he’s beaten everyone he’s played against, including Saitama and the best gamer among the Blizzard Group.
  • Hell Is That Noise: In universe they call it the King Engine. Like thundering timpani, it can be heard when the thrill of danger approaches him. Villains and monsters know it is the sound of impending doom, for they believe it is the excitement King feels whenever he has the opportunity to kill something. In reality it's his heart hammering around in his chest, as he's scared out of his wits..
  • Heroic Build: He has a large muscular body in contrast to Saitama's slender build, which is surprising considering he spends most of his time playing video games and collecting Otaku memorabilia.
  • Hidden Depths:
    • Gives a rather inspiring pep-talk to Saitama in the manga when the latter is feeling especially distressed over the lack of challenge he faces in the world. Granted, it's taken from a manga that King read and King himself is just an ordinary person, but it shows that King, more than anyone else in the series, is able to relate to and offer advice to Saitama.
    • He seems to understand Saitama the most, thus when he sees Genos writing down advice Saitama gave him, King inwardly feels that Genos is wasting his time trying to get life lessons from Saitama of all people.
  • Humble Hero: While he's not as strong, brave, and powerful as people and other heroes like to believe, he's one of the nicest guys in One-Punch Man and very modest. Of course, given his reputation, this bites him in the ass because when he tries telling people the truth, he's mistaken for being unwilling to take the credit for his supposedly awesome achievements. The problem is, he's unwilling to tell the truth since he couldn't bear to see the potential reaction, even though he hates his reputation.
  • I Owe You My Life: He got his scar from an Octopus-Claw Man that attacked one day, and if it wasn't for Saitama, he might have died then and there. It takes a while for him to recognize Saitama again, due to him not having his hair, but it's what cements the beginning of his friendship with Saitama.
  • I'm Not Afraid of You: Many monsters have tried this claim against King. He just continues staring at them, very intently. They don't keep their courage for very long after that. And King gets a moment to play this too; although he's scared of the amassed monsters of the Monster Association, he still is able to make them immediately be on-guard through using his reputation alone and is able to scare Homeless Emperor with a small comment about him watching his step. He ultimately bullshits and intimidates them long enough for Blizzard to arrive to face Psykos, Zombieman to grab Homeless Emperor from beneath the rubble, and the rest of the heroes (minus Saitama, unfortunately) to show up to deal with Black Sperm and Evil Natural Water.
  • Inexplicably Awesome: A subversion. King is regarded as the strongest hero by the populace, but no one knows why he's so badass. It seems that the general consensus is that King "did something" to that monster who is now lying dead before his feet, but no one is quite sure what he did and how he did it. Of course, King didn't do anything to the monster and was just the only guy there after Saitama punched the monster and left.
  • Lucky Seven: Ranked 7th in the S-Hero rankings and is a normal guy possessing borderline divine level of luck that permit him to save himself and others when the situation calls for it.
  • Memetic Badass: This guy is essentially the Chuck Norris/Rajinikanth of the One Punch Man verse, except everyone believes he is actually this.
    "So... so that one time when you flew into the sky holding the bomb that can destroy the entire solar system and hurling it into a giant black hole... and that one time Mr. King traveled into the past to destroy all those meteors headed towards Earth, so that the history of mankind could exist... and the rumor that there's a hidden message within almost every legend that foretold the coming of Mr. King."
  • Mistaken for Badass: He's the one who got the credit for all of Saitama's superhero deeds (from the very first chapter with Vaccine Man and even before that) since he happened to be the only man in the vicinity.
  • Moe: King is seen purchasing several products with cute girls on the packaging, and tends to play them in fighting games.
  • Muggle Best Friend: Played with — Anyone who sees King and Saitama together playing video games would think Saitama is the "normal guy" hero (being a B-Class) to King's "Superhero" (being a S-Class) — that is, if they don't think Saitama is trying to boost himself via this friendship somehow, or if the neighbors don't get cowed into being awestruck because, y'know, KING IS VISITING RIGHT NEXT DOOR (and might even ANSWER THE DOOR POLITELY IF YOU KNOCK) — But it's actually the other way around.
  • Odd Friendship: He and Saitama become pretty good friends despite being complete opposites on paper and in reality, both seeing each other for exactly who they are. They also play video games together a lot, the one thing King can actually beat Saitama at with zero effort.
  • Oh, Crap!: When Saitama went to his apartment and caught him playing "Doki Doki Sisters."
  • Otaku: Downplayed. King is respected member of his community with decent social skills, but his personal life revolves around video games, manga, and old TV shows.
  • Only Sane Man: Out of all of the heroes in the S-rankings, King is the one with both his feet on earth and the most humane of the bunch. Due to actually being a normal guy with no interest in getting involved with any of the other's antics or the Hero Association in general.
  • Outscare the Enemy: How King defeats his opponents, with a little help from "the King Engine", which is the DOOM DOOM DOOM sound he gives off which turns out to be King's own heart as he tries not to freak out.
  • Paper Tiger: Even without his reputation, from his looks alone, one could imagine very few people would mess with him anyway.
  • Perpetual Frowner: Always wears this expression. Except when he's alone during a dangerous situation, in which event his expression breaks and is replaced by sheer terror.
  • Poor Communication Kills: Played with — King doesn't get a word in on any sort of discussion most of the time, which leads to odd misunderstandings such as Child Emperor mistakenly thinking King can fire laser beams. This gets the S-Rank heroes into serious trouble (until King draws attention to himself by pretending to do the move), which just makes his reputation reach even greater heights because "he used a special move to save all the S-Class heroes" is all that will get circulated in rumors later.
  • Rugged Scar: Has a big claw mark over half of his face, which adds to his already intimidating appearance. The Hero Association believes that the scar was given to King during his fight against a God-threat level monster. He actually got it from a Tiger-level threat that Saitama defeated back when he still had hair.
  • Sadly Mythcharacterized: In-verse, King's reputation and acclaimed feats, created and circulated by society, have reached the level of exaggeration bordering of sheer absurdity that not even King can believe people honestly can buy without a second thought.
  • Snowball Lie: Played with — the lies are spread by other people, and almost every time that it seems like the bluff might get called, something happens that is both extremely lucky for King, because he no longer has to prove he can fight and usually happens in a manner that somehow gives King all the credit for his incredibly lucky windfall so he gets an even bigger reputation for being the ultimate hero.
  • The Stoic: Played for laughs — see that really tough expression as his profile picture? That's the face he makes to stop himself from expressing absolute terror.
  • Terror Hero: His reputation is such that he can defeat monsters by causing them to faint out of fear. It's a good thing, too, since he's as powerful and strong as a normal human.
  • That One Player:
    • Later in the story, Saitama gets to know his secret, and becomes his gaming buddy. King is VERY good at games, to the point where the reputation about his battle prowess he's earned actually applies to video games, such as absolutely broken infinite combos and being able to beat really hard games with one hand. To the point that he made Saitama rage and scream "This game is shit!"
    • This comes in handy in an extra chapter when Blizzard challenges Saitama and his "Saitama group" (Genos, Bang, and King) to a competition as an attempt to force them to join the Blizzard group. When it turned out the challenge was a video game competition, King single-handedly beat all 30 opponents including one member who happened to be a former pro-gamer, that defeated Bang, Genos, and Saitama effortlessly (granted, none of them were any good at the game).
  • This Looks Like a Job for Aquaman: He's actually a Muggle, and he's actually useless when it comes to fighting monsters. He does save the day with his EVO-level gaming skills one time, though.
  • Unluckily Lucky: His backstory has him run into many monsters only to be saved by Saitama constantly. Then people mistook him for a Hero and he got the honor of becoming an S-Class Hero with all the prestige it implies, but also all the pressure from the expectation of the population.
  • Victory Through Intimidation: King can turn the tide of a battle simply by showing up — his reputation alone makes monsters and heroes alike freeze in place, and villains that randomly run into him on the street literally have a stroke because he's that big of a surprise. And if you try to attack him? all you hear is DOOM DOOM DOOM DOOM DOOM, which can make even the most hard-hearted monster falter with doubt and reluctant to hit him, in case of it being fatal to themselves to even touch him. It's a good thing too, considering King has the fighting ability of a completely normal person.
  • Walking Spoiler: As can be seen with all the spoiler tags here — it's quite The Reveal as to the source of his abilities and prestige.
  • Weirdness Magnet: King has the uncanny ability to seemingly attract monsters to himself like honey attracts fruit-flies, despite not even trying or intending to do so. His ability of surviving these encounters with only dead monsters in his wake is the reason he was promoted to S-Rank in the first place. despite being only a mere bystander at the scene every single time it happened.
  • Wild Card Excuse: King is mostly busy because he's fighting monsters and/or raiding monster lairs. He's actually just playing an RPG, but his statement saves him from having to actually fight monsters.
  • World's Strongest Man: Despite his actual ranking in the Hero Association, King is regarded as the strongest hero, respected by most heroes and feared by even the strongest monsters. His feats of killing fierce monsters with ease are renowned by all and are almost of a mythical nature. In actuality, he's just a normal guy, who simply happened to be at the wrong place at the right time.
  • Your Mind Makes It Real: King fakes knowing a special move as a bluff against Black Sperm and Golden Sperm, but his courage allowed him to manifest it into an actual attack, at least in his head.

    8. Zombieman 

Zombieman

Voiced by: Takahiro Sakurai (Japanese), Vernon Dew (English)

Debut: Chapter 32 (Webcomic), Chapter 29 (Manga), Episode 10 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/zombieman_anime.png

Zombieman is a nearly completely immortal superhero who can regenerate from almost any injury. Thus, he prefers to relentlessly fight and let Monsters tire themselves out with futile attacks. He wields various weapons, including an axe and different types of guns.

He's a product of the House of Evolution, where his codename was "Subject #66".


  • An Axe to Grind: He carries an axe as one of his weapons.
  • Artificial Zombie: He was an experiment from the House of Evolution.
  • Badass Longcoat: He wears a typical hard-boiled detective's longcoat, which suits his usual line of work.
  • Berserk Button: A mild one, but saying he's not human or calling his humanity into question visibly pisses him off.
  • Clothing Damage: His body can regenerate, but his clothes can't. After being blown apart by Homeless Emperor, he spends most of the Monsters Association arc completely naked.
  • Combat Pragmatist: In the middle of his introduction to Pureblood, he starts shooting at the monster.
  • Crazy-Prepared: Keeps an extra gun hidden in his chest. He's also somehow able to fire it from the inside for a surprise attack.
  • Cute Monster Guy: What characterizes him as a zombie is his gray skin, incredible regenerative abilities, and seemingless inability to die. But unlike typical zombies who usually involve Body Horror in their designs, he has an attractive face and a well-built figure. At least, once he's finished regenerating. He can momentarily look just like a disfigured zombie after being damaged enough, but only temporarily.
  • Dark Is Not Evil: Zombies are traditionally considered an undead monstrosity, not to mention that he comes from the House of Evolution. Despite all of that, Zombieman is actually one of the most heroic characters in the series.
  • Determinator: He once fought against mysterious beings in a fierce battle for 140 hours and emerged victorious.
  • Establishing Character Moment: Outside of a cameo in the alien invaders arc and a short scene where he follows Marshall Gorilla, his first real scene is when he finally finds the trail of the scientist who created him – Dr. Genus, the head of the House of Evolution. He believes that Dr. Genus is behind the Monster Association and other bad things that have been happening, and seeks to kill him. When Dr. Genus tells him that the House of Evolution has been disbanded, Zombieman threatens him with an axe and demands to know why. The discussion shifts to how Saitama (his name isn't mentioned but the reader knows who he’s talking about) basically crushed his evil ambitions. Zombieman, seeing that Dr. Genus has actually been "defeated" to the point he's dramatically changed and has no plans to rebuild his organization, actually puts away his axe instead of killing him.
  • Exploited Immunity: How he defeats Homeless Emperor. The hero pins down Homeless Emperor and makes sure to keep the monster close to him. Zombieman can regenerate from Homeless Emperor's destructive attacks but Homeless Emperor, whose body is that of a normal human's, cannot. So since Homeless Emperor cannot attack Zombieman without hurting himself, Zombieman wins.
  • Gradual Grinder: An unusual type; while he doesn't poison his enemies, he's so durable that he will inflict damage one way or another, even if slowly, until his enemy is dead.
  • Guns Akimbo: During the Monster Association arc, he uses two large pistols in conjunction for lesser monsters.
  • Hand Cannon: He carries around pistols with such firepower and force behind them the recoil alone is capable of breaking his arms with each shot, to say nothing of what happens to nearly any monster on the receiving end.
  • Healing Factor: Probably one of the most impressive in the series. It's so fast that one of Pureblood's bats that he sent to try and overwhelm said regeneration couldn't escape in time and was absorbed into Zombieman's body.
  • Impaled with Extreme Prejudice: He gets run through with Atomic Samurai's sword in the sixth OVA. He gets better, naturally.
  • Implacable Man: He WILL be back to kick your ass no matter how many times you knock him down. He will NEVER stop or surrender pursuing you if you're a threat.
  • Irony: His weapons are a pistol or an axe. These weapons are stereotypically depicted as popular weapons to use against zombies in zombie movies.
  • Law of Inverse Recoil: He wields two large handguns that fire with enough force that both his arms are broken with a single shot.
  • Ludicrous Gibs: When he pulls out a sharp object, someone's gonna get chopped into pieces, and the battle turns into a messy bloodbath. Sure, most of the time all the limbs and blood scattered around are usually Zombieman's, but the difference is Zombieman's wounds heal and his limbs come back, and his opponents' usually don't.
  • Major Injury Underreaction: Since he can't be killed, his only serious reaction to any injury is whether or not it's going to slow him down while he heals.
  • The Mole: Amai Mask briefly insinuates that he's no more than a Monster who's using the Association to hide from justice. Zombieman, while he doesn't go into a rage about it, is still pretty pissed at the accusation.
  • Nice Guy: He seems to be on pretty good terms with most of the other heroes, forgave the former evil scientist who used to experiment on him, and was concerned for Saitama's safety during his fight with Garou. He didn't even get mad at Tornado for stabbing him to death, since it had no lasting effect on him.
  • The Quiet One: Very quiet, hardly speaks unless out of necessity or frustration.
  • Resurrective Immortality: Exactly What It Says on the Tin. He cannot be killed, as he will just regenerate.note 
  • Revenge: Subverted as part of his Establishing Character Moment. It's implied that he spent most of his life after escaping from the House of Evolution searching for revenge, but once he actually has the leader at gunpoint, he's willing to listen to them and ultimately lets them live once he's convinced they're genuinely reformed.
  • Terror Hero: Comes with being a zombie — the concept of a hero that just won't stop until you are either under arrest, defeated, or dead, slowly but surely terrifies his enemies. Because almost nothing can kill this guy, nothing can get in his way, and he can hunt night and day to find and capture you. In fact, it's this sheer determination quality alone that got him into the ranks of the S-Class in the first place, which makes him the only S-Rank Hero that got in due to his pure, absolutely unkillable defense, instead of the absolute offensive strength that usual S-Rank Heroes have.
  • Too Spicy for Yog-Sothoth: According to Pureblood, Zombieman's blood is so nasty that he could barely swallow it after trying to drain him dry.
  • Victory by Endurance: Both his victory over Pureblood and his follow-up fight against thirty more monsters amount to "Keep taking hits until I kill them".
  • Weak, but Skilled: He doesn't have freakish strength (or much offensive capacity beyond a normal human's), but his main skill is being unable to die. EVER. And when you can regenerate from practically anything, you don't need to be terribly strong when you can simply outlast the strength of your enemy.
  • Why Won't You Die?: Gets this a lot from his enemies, mostly because no matter what, HE. JUST. DOESN'T. DIE. Blow his arms off? They come back. Blow his entire body to bits? They just regenerate together. Decapitate him? All that does is slow him down. Word of God states that he would die if he's "reduced to mincemeat," but getting him to even that point is no small feat in and of itself, as his body instantly starts regenerating the moment it's damaged, and even if you try to continuously damage him it won't stop him from closing the distance and attacking without remorse.
  • You Are Number 6: Subject #66 of the House of Evolution.

    9. Drive Knight 

Drive Knight

Voiced by: Yoji Ueda (Japanese), Todd Haberkorn (English), Armando Guerrero (Latin American Spanish)

Debut: Chapter 32 (Webcomic), Chapter 29 (Manga), Episode 10 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/drive_knight_anime.png

A mysterious hero clad in black armor who seems to only have one eye. Drive Knight uses a box containing technology which can transform into any tool suited for his purposes to fight. He's suspicious of Metal Knight and warned Genos about him.


  • Ambiguous Robot: Is he a robot? A cyborg? A guy in a mechanical suit? Who knows?
  • Awesome by Analysis: He'll come up with a winning strategy against even powerful monsters, but only after he has all possible information on his enemy, and won't fight any other way. Even if it means hanging back while several other Heroes get mauled by said monster to get that data.
  • Badass Biker: His Lance form turns him into a driver stuck to a motorcycle, with which he's very proficient.
  • Big Damn Heroes: After mysteriously disappearing during the Monster Association's initial rampage, he shows up out of nowhere to save the surface team from Nyan.
  • Blade Below the Shoulder: One of the many forms he can shift his technology into, and it's sharp enough to slice through the heads of multiple monsters with one swing.
  • Chess Motifs: Drive Knight's modes are named after shogi pieces, from "lances" to "bishop" and even a "gold" mode referencing the golden generals of a shogi set.
  • Cyber Cyclops: He has a single shining red eye on his face.
  • Dynamic Entry: How he announces himself to a group of monsters eager to start rampaging: Charging in with his centaur form and ripping the lead one's head clean off as he passes by.
  • Hollywood Acid: Drive Knight can spray a powerful acid around him when in his motorcycle form. It is stated to eat through thin bodies faster, preventing Nyan from fleeing through yet another battle.
  • Machine Monotone: In the anime.
  • Mysterious Stranger: He's an obvious parody of them, as absolutely nobody knows who he actually is.
  • Our Centaurs Are Different: They're mechanical for one thing, and it's just one of many forms he can turn into with his ability to manipulate hardware.
  • Playing with Fire: Drive Knight's Gold form gives him the ability to produce enormous amounts of heat, enough to kill Nyan, a Dragon level monster. When Nyan infiltrates the gold armor, Drive Knights triggers his ability and incinerates Nyan.
  • Pragmatic Hero: He actually could have saved the surface team from Nyan earlier, but chose to stay back and observe the fight for a while so he could properly analyze Nyan's abilities. He's called out for not helping sooner, but he explains that he needed all the information he could get to defeat Nyan to prevent further casualties.
  • Rocket Ride: His Flying Chariot mode attaches him to a rocket that allows flight.
  • Size Shifter: Not Drive Knight himself, but his mechanical prism is seen as being a block of technology smaller than he is, yet capable of turning into equipment of varying sizes from a sword a bit longer than his arm to a bike larger than his whole body. Most notably when he's seen transforming into two armored modes with one a hulking robot several times his size and the other a more compressed form-fitting one. All presumably from the same volume of tech.
  • The Stoic: Never changes his tone even when he's brutally slaughtered a group of monsters and threatening the last with torture if he doesn't give him the info he wants.
  • Swiss Army Weapon: Drive Knight uses a big prism of hardware which can seemingly transform into many types of weapon and equipment.
  • Technopath: His main power, which he refers to as "Tactical Transformation". By carrying around a giant mechanical prism of hardware, he can manipulate it into all manner of forms, from an electrified Blade Below the Shoulder to even constructing a mechanical centaur half for fast travel.
  • Transforming Mecha: Drive Knight's fighting ability revolves around his ability to turn into specialized forms. For instance, his Chariot form turns him into a centaur, or his Bishop form turns him into a hulking robot with particularly powerful punches. They are also extremely fast, enough for him to transform in the middle of a battle and even take a Dragon level monster like Nyan by surprise.

    10. Pig God 

Pig God

Voiced by: Daisuke Namikawa (Japanese), Marc Diraison (English)

Debut: Chapter 32 (Webcomic), Chapter 29 (Manga), Episode 10 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/pig_god_anime.png

A morbidly obese man who can swallow and digest anything. He mitigates incoming damage with his thick layers of fat. Seemingly obsessed with eating, Pig God is nonetheless a dedicated Hero.


  • Acquired Poison Immunity: Implied. He's able to eat and digest a giant venomous gorgon whole without worrying about getting poisoned, so it's likely he's used to eating such kinds of monsters.
  • Acrofatic: Pig God was noted to be able to move quickly, despite his injuries and massive weight.
  • Always a Bigger Fish: The first monster he faces in the Monster Association is one who threatens to swallow all the heroes whole. What happens? Pig God swallows him whole.
  • Big Damn Heroes: Saves Child Emperor from Eyesight.
  • Big Eater: He's constantly seen eating. In his debut, he was eating during the S-Class meeting. In fact, his only request from the Hero Association upon becoming S-Rank was a constant flow of high calorie meals.
  • Eating the Enemy:
    • How he deals with monsters. It's as disgusting as it sounds.
    • Strangely, this is also how he keeps his fellow heroes from harm... by swallowing them and keeping them safe in his cushioned belly until he can safely cough them up.
  • Extreme Omnivore: He can pretty much eat any monster regardless of what they're made of and digest them almost instantly.
  • Gonk: But considering he's like 500 pounds overweight, it's to be expected.
  • Nice Guy:
    • Although his characterization seems unsympathetic at first, making him seem like just a Fat Bastard, he drags himself (while severely injured) all the way from the hospital to a recent battlefield in order to make sure none of the monsters he fought can escape, telling the people who come to get him that it's his responsibility.
    • Earlier, he is also heard muttering quietly to himself about some kind of prophecy, believing that his greatest act of heroism would also coincide with his death. He is naturally scared to die, but not for himself. He's scared because if he dies, who would protect the people?
  • Stout Strength: Pig God is strong enough to run through concrete walls.
  • There Was a Door: He simply walked through an entire city block to assist Child Emperor in his fight against Eyesight, as if it wasn't even there. When asked why, he replied it was simply the shortest route.
  • Would Hit a Girl: Had no problems eating Eyesight to save Child Emperor's life.

    11. Superalloy Blackluster 

Superalloy Blackluster

Voiced by: Satoshi Hino (Japanese), Zeno Robinson (English), Carlos Torres (Latin American Spanish)

Debut: Chapter 32 (Webcomic), Chapter 29 (Manga), Episode 10 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/superalloy_blackluster_anime.png

Superalloy Blackluster is a musclebound bald man with shiny muscles, hence his name. Said to be the strongest hero in terms of raw physical power, Superalloy Blackluster fights Monsters mainly to comfort his ego.


  • Ambiguously Brown: Blackluster is very tan, to the point one may think he's a Token Minority, but a flashback shows that his natural skin color is not brown.
  • Bald of Awesome: He used to have real Samson-like hair to go with his physique, but then he realized his body wouldn't be truly shiny with hair, which is why he trained until he went bald.
  • Blood Knight: Subverted. He thought he was looking for an opponent that could push him to use 100% of his power, but when he finally fights against Garou, he realizes that what he wanted wasn't so much a "good fight", as a fight that could make him feel good about himself. He never considered the possibility that he might actually lose. He was looking for an equal, not a superior. After the Garou arc, he's shown falling victim to his fears of loss no matter how much he trains.
  • Captain Ethnic: Though he was shown to be fair-skinned before being truly "shiny".
  • Charles Atlas Superpower: His origin story even shows him as previously being a weakling who was bullied, and who worked out to become super muscular.
  • Color Character: His name literally means that he's a black guy with a shiny muscular body.
  • The Dreaded: He's said to be one of three heroes you must never anger, the other two being Tornado and King.
  • Everything's Better with Sparkles: His entire body produces sparkling Bishōnen effects when he flexes his muscles and poses (Which he does a lot).
  • Foe-Tossing Charge: Blackluster is so strong, he can reduce monsters into mincemeat by running into them.
  • Heroic Self-Deprecation: Amazingly enough — it turns out he trained hard to make himself feel a lot better about himself so he could try to avoid this, but being beaten by Garou briefly puts him into a funk until he gets snapped out of it. Even after Garou is defeated, his anxiety over losing remains.
  • Muscles Are Meaningful: It's the centre point of his heroism — his muscles keep him from being harmed and make him extremely strong.
  • Retired Badass: As of chapter 110 in the webcomic, he quits the Hero Association and joins the Neo Heroes not as a hero, but as a trainer and sparring partner.
  • Scary Black Man: Subverted, he might have the appearance of one, but is actually a nice fellow who tries to make the other S-Class heroes get along with each other.
  • Super Toughness: That body of his isn't just for show, you know. Most monsters can't even bruise his skin, because apparently the shine protects it.
  • Training Montage: He gets one in a flashback that shows how he got his super shiny body — he lifted weights every day, going from a skinny scrawny guy who could barely lift into a super-buff weightlifter. There were two effects: His body became so strong his muscles actually shone, and he became bald.
  • Unskilled, but Strong: He's never used anything more advanced than simple punches and tackles, but thanks to his insane natural strength and durability, he doesn't really need to get fancy. He once sparred against Bang and despite taking no damage, lost the fight badly because Bang is a much better fighter than him.
  • Walking Shirtless Scene: He's only ever seen wearing a black speedo.

    12. Watchdog Man 

Watchdog Man

Voiced by: Yuji Ueda (Japanese), Arnie Pantoja (English), Alberto Bernal (Latin American Spanish)

Debut: Chapter 32 (Webcomic), Chapter 29 (Manga), Episode 6 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/watchdog_man_anime.png

Watchdog Man is a Hero wearing a dog suit. His silence and comical appearance belie incredible strength, as Watchdog Man is able to rip apart Monsters with his bare hands, enabling him to singlehandedly protect his city.


  • Almighty Janitor: Was tearing the heads off Demon-level monsters with no effort since he was C-Class. He is also the only hero in charge of the most dangerous city, takes out more monsters than anyone else, and is the ONLY S-Class hero that has never struggled in a fight on-screen. On top of all this, he never reports anything to the Hero Association, meaning he moved up the ranks purely from being seen fighting. He could very well be the most powerful S-Class hero, barring Tornado and Blast.
  • Animal Motifs: In case you missed something, his motif is of a dog — he took the term "city watchdog" literally, so he wears some sort of dog costume.
  • Atop a Mountain of Corpses: The first time we see him, he's sitting on top of the pile of slain monsters.
  • Beware the Silly Ones: He may dress and sometimes act like a dog, but don't dare underestimate him, because he can rip through hundreds of monsters with ease. He's been slaughtering Demon/Dragon-level monsters with his bare hands alone since his C-Class days. His dog-like fighting style also lets him effortlessly fight off Garou in their manga-exclusive fight, since Garou's techniques are meant for fighting proper humans, as opposed to one imitating a dog.
  • Confusion Fu: Garou pegs him as Unskilled, but Strong, but in reality, he's this. He fights less like a human and more like a wild beast, which causes Garou to severely underestimate his battle skills.
  • Creepy Monotone: In the anime, he speaks in flat monotone, no matter what the situation is.
  • Curb-Stomp Battle: In the manga, during the Monster Raid arc, he fends off Garou with no problem, showing he's far superior in speed and strength. Garou noted that he fights like an animal, and the martial arts he himself uses is meant to be used to fight humans, rendering it ineffective against Watchdog Man.
  • Killer Rabbit: Look at him and you won't think he's a hero. Cross him, however, and be prepared to be ripped apart.
  • Lethal Joke Character: When he says there's "nothing interesting to report", what he actually means is "Now that I'm here, I killed practically every monster in the area, and now there is no longer anything left to report to you".
  • Non-Standard Character Design: His face is drawn even more simplistically than Saitama's "relaxed" state, making him always appear bored or apathetic. Unlike Saitama, he is never drawn any other way and never shows any range of emotions. Seeing as only the very strongest characters in the franchise's setting are drawn this way (including Tatsumaki as well), it's a prime hint that Watchdog Man may have reached a similar level through his constant monster battles.
  • The Stoic: Appears even more apathetic to his surroundings than Saitama, but is very diligent in his role.

    13. Flashy Flash 

Flashy Flash

Voiced by: Kosuke Toriumi (Japanese), Lex Lang (English), Luis Navarro (Latin American Spanish)

Debut: Chapter 32 (Webcomic), Chapter 29 (Manga), Episode 10 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/flashy_flash_anime.png

Flashy Flash is the fastest of all the S-Class Heroes. He fights using his tremendous speed and mastery of swordsmanship to cut down his opponents with overwhelmingly fast slashes and thrusts.


  • The Ace:
    • Zombieman says that Flash is rumored to be one of the best fighters in the S-Class. Not only is he super-fast, but he’s also a talented swordsman who’s also proficient in unarmed combat. In the webcomic, he is able to kill the Hot Rod Brothers before either of them could even react. In the manga, he is the first S-Class shown to take down two Dragon level monsters single-handedly. He only even struggles with them because he was waiting for the opportunity to kill them both at the same time. He’s also the only S-Class hero who was able to dodge any of Awakened Garou’s attacks.
    • According to Gale Wind, Flash is the strongest member of the 44th generation of Ninja their village has produced. And as proven during their battle, he's more than capable of taking him and Hellfire Flame (being The Aces of the 37th generation and Demon-level threats aside) on at the same time, even after they turn into their Dragon-level monster forms.
  • Agent Peacock: Downplayed in that he lacks the flamboyant personality that is usually associated with this trope, but he wears high heels and has hair accessories.
  • Badass Cape: He wears a dark blue bodysuit with a long white cape over it. It usually gets splattered with blood.
  • Bishōnen: Flash has feminine features, sharp blue eyes, and long blonde hair. He could give even Amai Mask a run for his money.
  • Combat Stilettos: A rare male example. Flash wears high heels as a part of his outfit and does attacks such as "Flashy Kicks".
  • Department of Redundancy Department: Just like "Speed-o'-Sound Sonic", though "Flashy Flash" is a bit more on the nose than "Lightspeed Flash" would be.
  • Did You Just Flip Off Cthulhu?:'
    • After Tornado killed Hundred Eyes Octopus before him, he insulted and challenged her, claiming to be even stronger. Luckily, the other heroes stopped him.
    • He's the only member of the S-Class heroes willing to fight Amai Mask when he tries to muscle in on the planning for the assault on the Monster Association base, despite knowing both of Amai Mask's power and influence in the Association and the public.
  • Defector from Decadence: The ninja "village" was more like a single giant facility maintained by an organization that kidnapped children and raised them into killing machines, including Flash and Sonic. Flash and Sonic decided it was too evil to be allowed to exist.
  • Dub Name Change: The original Japanese name is more like "Lightspeed Flash", though the result does make it more obvious how redundant and ridiculous his name is meant to be, much like Sonic's is, at the expense of losing how both are specific references to their speed.
  • Dude Looks Like a Lady: Many fans thought he was a woman when he first appeared. However, his masculine voice tipped them off.
  • Genius Bruiser: Flashy Flash isn't just a fast ninja, he's a seasoned fighter who has deep insight in how people fight (allowing him to analyze the fighting style of two monsters with better speed and compensate through skill and prediction)
  • Genocide from the Inside: Flash killed all the teachers, staff, and his other students in order to destroy the Ninja Village from within. Of course it helps that the "Ninja Village" is actually the name of a group that specializes in taking in orphans just to train them brutally to become assassins in the criminal underworld.
  • Good Counterpart: To Speed-o'-Sound Sonic. Both are prideful, effeminate speedsters who take an interest in Saitama after he No Sells two of their attacks. They even share a technique, the "Wind Blade Kick". The manga version at least confirms that they came from the same ninja village. In fact, he's a good counterpart to the entirety of the village, with Sonic being the least evil of the rest of them, although he fits the spirit of the trope with Sonic more because Sonic's alone and a more major character.
  • Hard Work Hardly Works: Averted. Flash achieved his level of speed and skill through rigorous training, not some innate ability. As he tells Gale Wind and Hellfire Flame, he got as far as he did because he trained harder than anyone else in the ninja village and when the fallen monsters ask him what they lacked as they die, he only replies "more training".
  • Ironic Name: "Flashy" Flash is anything but flashy in reality except for his costume. His fighting style allows him to win before anyone can see he's won, he's neither a braggart nor a flamboyant man, and he's done a lot of work against underground criminals in private, purposefully omitting that in his reports. He is a ninja after all.
  • Katanas Are Just Better: Flash wields a katana with a round guard. He appears to be skilled in using it in combat, as he defeated a Demon level monster with it and later during the Monster Association assault slaughters dozens of lower-level ones at a time.
  • Light Is Good: His speed and color scheme make people associate him with light, and he's on the side of good.
  • Lightning Bruiser: So far, only Saitama and Garou have outclassed him in speed.
  • Long-Haired Pretty Boy: Very noticeable since unlike other characters who fall under this category, he doesn't tie it up.
  • Ninja: At least in the manga version where it's confirmed that he came from the same ninja village as Speed-o'-Sound Sonic, Gale Wind, and Hellfire Flame.
  • Pet the Dog: Compliments the A-Class Hero Shadow Ring's technique during the Monster Hideout Raid and asks where she learned it, which is quite possibly the nicest he's shown acting towards the lower-ranked heroes that doesn't come off as condescending.
  • Pride:
    • Like Sonic, he is so proud of his speed that, when Saitama evaded his first attack, he attacked him again despite knowing that Saitama was not an enemy.
    • He also has a large level of pride in his status as a S-Class hero as well as his abilities, to the point he gets pissed at Tornado killing Hundred-Eyed Octopus before him and at Amai Mask for trying to make himself the commander of the assault on the Monster Association (and by extension the S-Class heroes, despite only officially being A-Class) to the point of being ready to fight them.
  • Speed Blitz: Being a discreet and to-the-point Hero, Flashy Flash usually finishes off enemies in one decisive attack too fast for them to even see coming before they're cut down.
  • Stock Ninja Weaponry: Flash also carries a Kunai with him, serving as an emergency weapon when he has to defend against two comparable ninjas.
  • Super Speed: Flashy Flash lives up to his name, being so fast that he can move and attack faster than the ordinary person can see, run up cliffs casually, and instantly reach a giant monster's every weak point. In the webcomic, he killed Gale and Hellfire, two Disaster Level Demon mysterious beings who took great pride in their speed, before they could understand what had happened. In the manga, he easily keeps up with Gale Wind and Hellfire Flame, who both moved way faster than Sonic could handle. He is the only S-Class hero who managed to dodge any of Garou's attacks after his transformation.
  • Underestimating Badassery: While he considers Saitama to be worthy, Flash is ignorant of the true extent of his strength. He presumptuously calls Saitama his disciple and has a sparring match with him. Needless to say, Saitama casually nullifies all of Flash's attacks and outmaneuvers him. Flash also believes Garou was considerably weakened by the S-Class heroes when the truth was they were too fragile for him and that Saitama was the one who crushed him for good.
  • Well-Intentioned Extremist: His sense of justice made him want to bring down and destroy the Ninja Village, stopping them from taking children and turning them into killers ever again. Unfortunately, his solution meant to kill everyone associated with the facility to make sure no trace of them existed.
  • We Used to Be Friends: This is how Flash is connected to Sonic. They were both in the same class who deliberately held themselves back so they'd get the most brutal, yet best training possible. They planned together to stop the Ninja Village once and for all from taking in and raising kids to be brutal killers, but Sonic grew distant and cold when he ended up using his abilities working for criminals.

Tank-Top Master

Voiced by: Katsuyuki Konishi (Japanese), Patrick Seitz (English), Raúl Solo (Latin American Spanish)

Debut: Chapter 32 (Webcomic), Chapter 29 (Manga), Episode 10 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/tank_top_master_anime_9.png

Tanktop Master is the head of the Tanktopper Army and uses the Tank-Top fighting style. He is very strong and is actually a decent person, but gets overshadowed by his fellow S-Class Heroes.


  • Asskicking Equals Authority: He's the highest ranking practitioner of the "Tank-Top" fighting style and is the master to all the other Tank-Tops.
  • Badass Normal: One of the few S-Class heroes who doesn't have a gimmick other than being incredibly strong.
  • Charles Atlas Superpower: In some chapters, it is shown that he gained his strength through doing rigorous workouts, like carrying absurdly heavy weights. He can lift building debris many times his size with one arm.
  • Clothes Make the Superman: Parodied. He, along with the other practitioners of the Tank Top fighting style, apparently draw their strength from wearing tank tops, though usually this comes with some other gimmicks and plenty of strength training.
  • Fantastic Fighting Style: Parodied with the Tank Top fighting style, which he is a master of. Apparently, wearing a tank top gives you super powers, and its "versatility" can be used in various ways to kick an opponent's ass.
  • It's All My Fault: After the Garou arc, he notes that many other Tanktop heroes have retired and blames himself for losing, believing that was being a catalyst for the others to lose hope.
  • Jobber: He's the only S-Rank Hero that gets humiliated every time he appears. Tornado shows him up using her psychic powers during the alien invasion, he attacks the drones Metal Knight was using to rebuild A-City and feels inadequate once the project is finished in a week when it would have taken him hundreds of days just to clear the rubble, and later Garou succeeds in beating him, which boosts his confidence and makes him decide to graduate to fighting S-Class heroes..
  • Overshadowed by Awesome: He's strong enough to be a S-Rank hero. It's just that Tornado, Metal Knight, and Garou are far more formidable than he is.
  • Reasonable Authority Figure: Compared to the most of the others who use the Tanktop Fighting Style, he's actually a decent guy.
  • Running Gag: Defeat or humiliation is what always happens to the members of the Tank Top Army.

    16. "Metal Bat" / Bad 

Bad

Voiced by: Wataru Hatano (Japanese), Sam Riegel (English), Eduardo Ramírez (Latin American Spanish)

Debut: Chapter 32 (Webcomic), Chapter 29 (Manga), Episode 10 (Anime)

https://static.tvtropes.org/pmwiki/pub/images/metal_bat_anime.png

Bad, a.k.a. Metal Bat, is a hot-blooded delinquent who wields a metallic baseball bat. Not only is he strong and insightful in battle, but the angrier he gets and the more damage he takes, the more powerful he becomes. Metal Bat can shrug off the gravest wounds to continue fighting. He is fond of his little sister, Zenko.


  • Affectionate Parody: Of a certain type of Shōnen hero. Specifically those like Yusuke Urameshi and Ichigo Kurosaki who tend to be Japanese Delinquents with a Face of a Thug and matching personality while still being unexpectedly heroic. No matter what fantastic powers they possess their biggest asset tends to be their unwavering will to win.
  • Almighty Janitor: Was taking out Demon level threats back when he was in C-Class.
  • Badass Normal: Possibly. It's unclear whether his ability to get stronger as he gets angrier and takes more damage is natural or not.
  • Batter Up!: He wields a metal bat, which doesn't seem to break or get damaged. Before his promotion to S-Class, he went through a ton of normal metal bats. Upon his promotion to S-Class, the Hero Associate decided to give him anything he wanted as a celebratory gift. He requested an unbreakable bat.
  • Bullying a Dragon: He tried to pick a fight with Tornado, in spite of her rank and Superpower Lottery after she insulted him. Luckily for him, Flash defused the situation before the fight could take place.
  • Coat Cape: How he wears his black jacket.
  • Critical Status Buff: In his fight with Garou, the latter notices that he becomes stronger the more damage he tanks.
  • Defector from Decadence: He left the Hero Association and joins the Neo Heroes as of chapter 110 in the webcomic. His motives behind this are unknown, though it may have been because of how low the Association has sunk following the whole deal with Garou.
  • Determinator: Part of his style is that he refuses to go down even after getting beat up. In fact, he becomes stronger and faster the more damage he takes and the longer the battle drags on. When Garou thinks he won, Bad gets right back up and is microseconds away from caving Garou's skull in. Zenko showing up is the only reason Garou’s hero hunt doesn’t end right there.
  • Everyone Calls Him "Barkeep": Even his own sister usually calls him Metal Bat.
  • Good Is Not Nice: He's a delinquent, is not afraid to say what he thinks, and is all too willing to get into fights with other heroes if they rub him the wrong way. However, he is a good guy deep down.
  • Heroic Second Wind: Murata's Centipede arc shows this is something he takes active advantage of. When he takes serious damage, he gets stronger and faster, something he describes as his "fightin' spirit". He can take an incredible amount of punishment, to the point of multiple bone fractures, and be ready for another fight.
  • Japanese Delinquents: During his C-Class days — he still has the pompadour to prove it.
  • Jerk with a Heart of Gold: Has a soft spot for his little sister and his cat.
  • Kindhearted Cat Lover: Has a pet cat named Tama. He was absolutely livid about being called out to fight a Dragon-level Kaiju on the day she was expected to give birth.
  • Made of Indestructium: The volume 11 omake depicting his promotion from C-Class to S-Class shows that his only request upon being promoted was for a metal bat that wouldn't break no matter what. It's seen that when he fought with an ordinary metal bat, it would end up bent out of shape afterwards.
  • Unskilled, but Strong: During their fight, Garou remarks that Metal Bat is strong, but lacks the skill needed to fight against someone who uses martial arts like Garou. Justified as other than his ridiculous strength and endurance, he's just a delinquent whose fighting style is simply "smash opponent with metal bat." This alone, however, allowed him to instantly go from C-Class to S-Class.
  • When All You Have Is a Hammer...: Metal Bat solves all his problems by smashing them with his metal bat.
  • Who Names Their Kid "Dude"?: Murata revealed that his real name is "Bad". It's canonized in Chapter 80 of the manga.
  • Would Hit a Girl: He was not afraid of challenging Tornado to a fight when she insulted him, showing that he does not discriminate genders at the time of fighting.
  • Younger Than They Look: He's seventeen, despite looking a tad older, which also makes him one of the youngest S-Class heroes.

Puri-Puri Prisoner is a burly man with flamboyant yet super powerful special moves who loves good-looking guys and addresses everyone with the suffix -chan. He is a strong Hero and usually a decent person, but chooses to live in prison lest he harass good-looking boys.


  • Arrested for Heroism: Played with — apparently he put HIMSELF into prison (with an infinite year sentence) because he didn't want to use his strength just to try and stalk guys. He literally breaks out of prison when given the call (he writes an apology note for the damage and promises to be back soon to make it okay).
  • Ass Shove: Guess how he carries his phone even when he's naked.
  • Badass Gay: He's an openly gay member of the S-Class Heroes.
  • Battle Strip: Flexing his muscles at 100% strength tears all his clothes, leaving him butt naked.
  • The Big Guy: Huge and ripped like no one's business.
  • Does Not Like Shoes: Puri-Puri Prisoner tends to go barefoot.
  • Everyone Has Standards: He may be a Stalker with a Crush to attractive men, but he does not hesitate to stand up to Amai Mask when the latter insults him and the S-Class heroes for the destruction of A-City.
  • Expy: Many people also notice he resembles Hugo/Andore from Street Fighter/Final Fight.
  • Fan Disservice: Every time that he fights nude. Even In-Universe the audience is always disgusted, with people choosing to leave rather than look at him naked.
  • Full-Frontal Assault: His "Angel Style" is simply him flexing his muscles so hard he tears off his clothes, so he fights in the nude.
  • Gentle Giant: As the lowest ranked hero in the S-Class, he seems to be more down to earth and genuinely heroic (barring the sexual harassment) than some of the more self-absorbed heroes in S-Class. He tells Saitama about Lady Shibabawa and her predictions when the former asks him about her, without caring about him being a B-Class hero in a meeting for S-Class heroes.
  • Gratuitous English: Almost all of his attacks have an English name that he yells before he uses them.
  • Ham-to-Ham Combat: His fight against Sea King — it basically boils down to "You call that an attack? THIS is a real attack!" over and over.
  • Heroic Build: Quite built (his muscles have muscles) and he's definitely a hero... Despite his strange "quirks".
  • Heroic Self-Deprecation: After both of them lost to Garou, he admitted to Superalloy Blackluster that he only does hero work so he can hook up with guys.
  • Humble Hero: When fighting Vacuuma, Puri Puri states that he's just an average human being compared to the other S Class Heroes. While he may not have the devastating skills or abilities as the other S ranks, his battles prove him to be far from average.
  • Large Ham: He can be... Really excessive when he wants to be, like a gay version of Alex Louis Armstrong.
  • Macho Camp: Muscled enough to rip all his clothes when he flexes, and camp enough that his superhero uniform's a cute little sweater with a big red heart in it.
  • Made of Iron: Though he still lost to it, the fact that he survived The Sea King's chain attack, and took no apparent long-term damage, speaks volumes for his toughness considering every strike was said to pack the intent to end his life.
  • New Powers as the Plot Demands: During the invasion of the Monster Association, he gains the ability to vibrate his body and increase his attack power after receiving several elemental attacks. Shortly after when confronting Nyan and the monsterized prison convicts, he spontaneously sprouts body hair that gives him further toughness he calls "Angelic Plumage" (much to the convict's disgust). While Puri Puri thinks this is all a result of his "deep overflowing love" awakening new abilities, Nyan thinks it's just simple evolution but is nonetheless disturbed by it.
  • Play-Along Prisoner: He only stays in prison because he put himself there. He breaks out effortlessly when he's on hero business.
  • Please Put Some Clothes On: People who see his Angel Style really want him to do this.
  • Prison Rape: Implied to be what he does to other inmates as punishment, though he'll sometimes let them off with just a French kiss.
  • Rapid-Fire Fisticuffs: His Angel Rush, and later Dark Angel Rush.
  • Real Men Wear Pink: Wears a hand knitted sweater with a heart on it made by his boyfriend, until he ripped it to shreds in his fight against the Sea King. He gets a new one before the Monster Association raid.
  • Rousing Speech: He gives one to Superalloy Blackluster after said hero experiences just how strong Garou has become and begins to think the battle is hopeless.
  • Self-Restraint: He put himself in prison to keep himself from assaulting pretty guys. This way, he only limits himself to the criminals sharing his cell block (including those he apprehended himself to build his own harem).
  • Took a Level in Badass: The Sea King really plays his attacks down and laughs at his conviction to protect men. During his fight with Melzargard, he even gets a small flashback of the insults Sea King threw at him... and then he shows off what he learned from that fight.
  • Transformation Sequence: Parodied in the anime, where he gets a magical girl-ish transformation scene that he calls "Angel Style" which results in his clothes simply being ripped off, leaving him completely naked.
