YMMV / One-Punch Man

  • Accidental Innuendo:
    Genos: What do you want with Sensei's meat?
    Fubuki: Demon Cyborg, Genos... are you truly satisfied under that man?
    • This line from Mosquito Girl:
    "Come here, little ones. Empty all your stored juices into me."
  • Adaptation Displacement: Most people would be more familiar with the anime than the manga, and there are certainly less people familiar with the webcomic than the former. Doesn't help that the art from the webcomic is crudely drawn, turning off people from reading the original one.
  • Alternative Character Interpretation: Is Saitama's "being a hero is just my hobby" thing him playing off a genuine desire to help as I Was Just Passing Through, or does he genuinely not caring about the big picture as long as he gets the immediate gratification of fighting a monster and saving the day? He's clearly a decent person in many respects, but it's possible to read the setting as a Crapsack World and Saitama as someone who genuinely doesn't really think or care about the horrific damage wrecked by the constant monster attacks it faces as long as he gets good fights out of it.
  • Angst? What Angst?: Saitama is pretty unfazed by the unwarranted hate mail he gets.
  • Arc Fatigue: The "Tournament Arc" in the manga. With ONE and Murata's long pauses the story is far from the end. Don't help the story is a "Filler" (even tough is One's idea, so it's canon) in the middle of the "Garou Arc" and some fans hate this.
  • Awesome Art: Both Yusuke Murata's redraw and the anime. Just compare ONE's original drawings (which aren't too bad themselves) to Murata's.
  • Awesomeness Withdrawal:
    • The anime has gained a massive following thanks to affectionate and off-the-wall parodying of shounen tropes, wonderful animation, and crazy cast. This is why the anime's mere 12 episode run (with no confirmed release date for season 2) has left many starved for more. Then season 2 was announced to be launched in the later months of 2016, probably around the same months of the first season's release. Now..... Subversion confirmed!
  • Base-Breaking Character:
  • Broken Base:
    • The fandom is pretty split between preferring ONE's original work and Murata's redrawn version, to say the least.
    • Naturally, the dub is polarizing to some degree. Some people think Saitama's English voice does his perpetual boredom justice, while others think it's missing a certain charm that the original Japanese voice had. In particular Genos' dub voice has garnered a lot of split opinions among viewers. Some think its a perfect match with Kaito Ishikawa and fits his serious militaristic personality while others find that his voice is incredibly forced and doesn't sound natural at all.
  • Cliché Storm: Well, it was created as a parody of shounen and superhero tropes in general. It is part of the charm.
  • Counterpart Comparison: King draws some comparisons to Mr. Satan from Dragon Ball Z, being a Muggle who's mistakenly believed to have taken down powerful alien threats. Both men are also quite skilled, but not in the way the public thinks they are. Unlike Mr. Satan, however, King isn't a Glory Hound at all, and in fact mostly finds his reputation to be a bother; he just doesn't have an easy way out of it.
  • Crowning Music of Awesome: Lots with the 2015 Anime by Studio Madhouse.
  • Draco in Leather Pants: Speed-o'-Sound Sonic certainly counts. Although Sonic is classified as a villain in-series, has made it his life's goal to kill Saitama, and has endangered innocent lives to goad Saitama into a fight, many fans often downplay his villainous actions. Although he does have genuine Pet the Dog moments, they only occurred in an anime-only OVA.
  • Ensemble Darkhorse:
    • Licenceless Rider only has a significant role in one of the story's arc but has gained a lot of fans, particularly after standing up to the Sea King (the aforementioned arc).
    • Blizzard, who doesn't even appear in the anime's first season, is second only to Saitama himself by a narrow margin in the 2015 character poll, outranking even Sonic, Licenceless Rider, and Genos. Keep in mind, Blizzard is a relatively recent addition to the band, especially in the Murata version where she's only been around for a handful of chapters. Her sympathetic motives and Action Girl status no doubt helped, as well as being a drop-dead gorgeous but tasteful Ms. Fanservice. As such, she's also had a number of special chapters centered around her. It's even brought up in the post-poll chapter, the Blizzard Group mentioning how she's had little screen time. She had this to say:
      Blizzard: "But not placing first doesn't feel right after all, which means I have to become the main protagonist."
    • Tatsumaki, for anime-only watchers. While manga readers know that she's a Little Miss Badass, her great design in the anime, and the fact that she's the first female hero introduced on-screen, garnered her an immediate following. For double the irony, unlike her sister Fubuki (who is actually shown to become part of Saitama's circle of acquaintances by regularly visiting his apartment, much like King), Tatsumaki only really gets to interact with Saitama in the webcomic after the Monster Association arc.
    • Mosquito Girl managed to place 9th in the character poll, despite only appearing for two chapters. Much like Blizzard, a lot of popularity is owed to her attractive design (for a woman that's part mosquito) and fanservice factor.
  • Epileptic Trees:
    • How Saitama actually achieved his strength. The only explanations we've received in-setting are Saitama's description of his training (which was treated as a ridiculously insufficient explanation even by the other characters) and a fairly vague conversation between Zombieman and the head of the House of Evolution about "surpassing his limiter." As a result, theories have been popping up like mushrooms.
    • Who Blast actually is. Not diminished at all when it was eventually revealed that Tatsumaki knew Blast from her childhood, as his similarities to Saitama have generated even more questions. Also not helped by the fact, depending on how one interprets Tatsumaki's monologue, Blast is not really unreachable, but actually missing.
    • With Word of God saying that Boros is above dragon but under god, people have been speculating who will be the God-Tier monster that will inevitably face Saitama in the future.
  • Evil Is Sexy:
    • Mosquito Girl: Despite being part mosquito, there is no denying that she is certainly attractive, even to a point that her good looks won over enough fans to be place 9th in the character poll.
    • Speed-o'-Sound Sonic: A handsome Bishōnen wearing a very form-fitting ninja suit that shows off his slender, yet muscular, figure. Even though he occasionally plays the role of Anti-Hero, he still counts.
    • Slingshot S (or "Do-S" depending of translation): Another Cute Monster Girl much like Mosquito Girl, but has a more human appearance. Her super revealing BDSM outfit certainly shows off her well toned, voluptuous figure.
    • Bizarrely enough, there is a section of female fans that finds Lord Boros attractive. It probably helps that he's a parody of bishounen villains.
  • Fandom Berserk Button: Moreso across all anime fandoms (and comic-book fandoms), but inserting Saitama into any Versus Discussion is bound to create this reaction. It is one of the primary reasons for the Fandom Rivalries listed below.
  • Fandom Rivalry:
    • With Dragon Ball. There have been wars over whether Saitama is stronger than Goku or vice versa. Ironically, One Punch Man is an affectionate parody of shounen tropes with characters being expies of Dragon Ball characters(e.g. Boros). Still, that doesn't stop fans from comparing who is stronger of the two. Dragon Ball Super in particular has a huge rivalry with the One Punch Man anime. The animation problems of Super has been a mocking point by fans of One Punch Man, since that series has some of the best animation in the industry thanks to Madhouse. Dragon Ball fans are quick to point out that the anime of One Punch Man should have better animation since the series is only 12 episodes while Super is an on-going series that will continue for an indefinite amount of time.
    • Same deal with Superman. This particular rivalry can get nasty since both fans tend to use the no-limit fallacy when discussing who's stronger than who.
    • My Hero Academia is also victim to this, due to the Fan Dumb unfairly comparing it to this, and some even going so far as to call it a rip-off, despite the fact that there have been other superhero-themed anime and manga before.
    • A much smaller rivalry has developed with the niche but dedicated fandom for Concrete Revolutio: Choujin Gensou which aired during the same season as One-Punch Man and also revolved around superheroes. While One-Punch Man quickly became a mainstream hit in the anime community, Concrete Revolutio remained very obscure and only got recognition from anime bloggers and critics.
  • Foe Yay:
    • Sonic's obsession with defeating Saitama shows signs of this. The anime furthered this with Sonic jumping towards Saitama for an attack but Saitama's fist ended up touching his genitals, although he apologized that he didn't mean to do that.
    • In Chapter 43, Sonic seeks out Saitama to fight him again in order to show his newfound strength. Predictably, Genos doesn't take too well to that, and the confrontation scene reeks of an ex meeting the new Clingy Jealous Girl girlfriend.
  • Friendly Fandoms:
    • There's been quite a few people that have noticed how much the series has in common with Empowered, what with all the superhero parody, kooky powers and supposed "loser" main protagonist. Not to mention that when it stops being funny, it REALLY stops being funny.
    • Fanarts comparing Saitama and Gudetama are also popular due to their similarities, from being lazy, looking like eggs (one is a literal egg while the other is usually drawn with an egg-like head.), having the same color scheme, and the fact that both their names end in -tama (from "tamago" meaning "egg" in Japanese).
    • With Fallout 4, weirdly enough, thanks to a mod that can customize the player character to look like Saitama and can even one punch all enemies with max stats. Basically, a god-mode mod for players to have fun with.
    • Obviously one with Mob Psycho 100 due to both works sharing the same creator (ONE).
  • Genius Bonus:
    • The Tree of Evolution shown behind Dr. Genus in episode 3 is the Ernst Haeckel's Tree of Life.
    • Why is Mosquito Girl a female? Because only female mosquitos drink blood.
  • Hilarious in Hindsight:
    • Yuuichi Nakamura's role as Licenseless Rider is pretty hilarious if you take into account he's the Japanese dub voice of Captain America in the Marvel Cinematic Universe.
    • The fact that there's a powerless bike-themed superhero constantly getting Overshadowed by Awesome, and it isn't The Bmx Bandit.
    • Kenjiro Tsuda (Atomic Samurai) is the Japanese dub voice of Kylo Ren, another swordsman, except being evil.
    • One for the Dub: Remember the time when some ballsy redditors covered the OP, and someone went full Large Ham screaming "IT'S BARGAIN DAY AT THE SUPERMARKET!!!"? Dub!Saitama says the line word for word in episode 3.
    • Licenseless Rider's main concept was a Kamen Rider parody without a license and rode an ordinary bike that he occasionally attacks with. Thanks to Kamen Rider Ex-Aid, there's now a license-less rider (Though, it's more like an unlicensed doctor who's a Kamen Rider)and a rider who rides a bike that he pedals and uses for attacks.
  • "Holy Shit!" Quotient: The series as a whole is full of this, from Saitama punching Vaccine Man in one hit, to punching a meteor, fighting an alien leader who can destroy worlds, (and who kicked Saitama to the moon!!!) an enemy who can defeat nearly all S-class heroes, and finally fighting Tatsumaki herself.
  • Hype Backlash:
    • Like every Anime season, there's one show that gets more hype and promotion than others, and OPM was no exception, especially when it was revealed Madhouse were animating it. So of course, lots of potential watchers are turned off by the more overzealous fans claiming it to be "Anime of the Year" and actively refuse to watch the show as a result.
    • The English dub was one of the most anticipated dubs of 2016 but a lot of people felt that it wasn't as big as it could have been. Being one of the most popular anime in years many dub fans felt it deserved a grand dub mixing all-star voice actors with exciting unexpected casting decisions and tons of marketing. The first red flag came however when the dub was announced out of the blue at AnimeExpo alongside a Toonami airing that would begin TWO WEEKS after the announcement with little time to hype up the dub. One common complaint with the dub is that it was a non-union dub which locks some voice actors out of appearing and that Bang Zoom doing the dub instead of Studiopolis further limited the talent pool for the dub. The cast in particular was criticized for lack of ambition in that most of the voice actors in prominent roles were regulars in Bang Zoom dubs and a lot of the more creative casting decisions or voice actors who were requested to be in major roles ended up only voicing minor characters. People still like it, as the actors are all considered at least decent at their roles, but they still feel it could have been so much better.
  • I Am Not Shazam: Despite what people may believe, Saitama is not actually called One Punch Man.
  • Launcher of a Thousand Ships: Saitama. If one looks at fanworks, he's shipped with everyone, with the most popular pairings being with Genos (due to Ho Yay) and the sisters Fubuki and Tatsumaki (due to interpreting their relationship as Belligerent Sexual Tension). Not bad for a bald guy.
  • Love to Hate: Several mysterious villains qualify, but the ones at the top are Boros and Garou. Boros for being the first enemy to survive Saitama's punch and for giving what fans consider one of the best fights in the series. Garou for being a crazy awesome villain that defeated the S-class heroes and would have won if it wasn't for Saitama.
  • Memetic Badass:
    • Saitama. In particular on VS forums where 'one punch' is the answer to many debates involving him. Hilariously, it's not a status he has in-universe. It's gotten to such a point that he rivals even Chuck Norris as the biggest Memetic Badass of all time.
    • King. After all, he's the strongest man in the world. Or not.
    • Watchdogman. A lethal joke character that wears a dogsuit that is guarding one city declared a hotspot of monster activities and shown ripping a monster head nonchalantly in one panel.
    • After his absolutely insane battle with Saitama, Lord Boros easily reached this status. Exemplified by the fact that he withstood three of Saitama's attacks, and had enough life left to have a final chat with his opponent.
    • Garou, after curb-stomping nearly every S-Class hero.
  • Misblamed: Some people blame Murata for making the story longer by adding fillers (like the Tournament Arc), however, all the things absent in the webcomic are One's ideas and/or are made with his approval. Thus they are canon.
  • One-Scene Wonder: This is bound to happen to every monster of the week thanks to being one punched by Saitama.
  • Periphery Demographic: The show got wider audiences with the announcement of the anime, but the fandom did not explode until it was actually aired on TV. It attracted even casual and non-anime viewers thanks to its newfound popularity and humor.
  • Rooting for the Empire: In a weird sense, in that it's not out of sympathy with the villains, but sympathy with the hero. A few fans have admitted that they couldn't help rooting for villains during a couple of Saitama's "battles", if only for desire to see someone that can be a Worthy Opponent for Saitama. Examples include Sonic, Boros, and Garou.
  • The Scrappy:
    • The Tanktop brothers are widely hated due to Tanktop Tiger being a sore loser and the brothers convincing the populace Saitama was the reason why the town got destroyed, even if he was the reason no one died in the first place. Thankfully Saitama put them in their place with a "Reason You Suck" Speech, and they don't appear to represent all the Tanktops, as Tanktop Master shows.
  • She's Just Hiding: Mosquito Girl, by virtue of having merely been sent flying by Saitama's swat, when the monsters he hits usually end up in Ludicrous Gibs (even the bloody smear she leaves on a building in the anime can be explained away as the result of her bloodsack rupturing on impact). It doesn't hurt that Murata has published artwork of her as a worker in Genus' takoyaki stand, complete with prosthetic limbs and a bandage above her buttocks, where her abdomen used to be.
  • Signature Scene:
  • They Changed It, Now It Sucks: Many were disappointed when the anime did not show the flip-book like scenes from the digital manga the series is famous for, instead using the tankobon version of the scenes.
  • Unintentionally Unsympathetic: Saitama after destroying the meteor. If he had taken the time to think things through, he might have realized that smashing the meteor into hundreds of pieces instead of using controlled force to redirect it back out into space might not be the best idea. Considering that the resulting debris destroyed the most of the city, you can't really blame the citizens for forming an angry mob when Tank Top Black Hole tried to incite them against Saitama.
  • Unpopular Popular Character: In-universe, Saitama is hated by nearly all citizens, save for a chosen few, for thinking he cheated on ranks and took credit from others' work. It's not helping that he is encouraging this mindset to let the others look good. Yet this is exactly the reason why fans love him outside the show, to the point where he's at the top of the character polls.
  • Viewer Gender Confusion:
    • Sonic. None of the characters have difficulty telling that he's a guy, which is likely due to his voice.
    • Lightspeed Flash. Same reason as Sonic. The fandom has joked that the two are related 'cause of their similarities.
  • Vanilla Protagonist: Invoked with Saitama. In his own words, he's just "a hero for fun" and his backstory is nothing more fantastic than "former salaryman does strength training until his hair falls out". He is a plain guy, his ungodly strength aside, he had no other defining features in contrast to the more colorful side characters like Genos. In the webcomic, even his art style feeds into this trope because he looks like a stick figure instead of a more detailed form like the other characters. As we find out, the webcomic explained that he truly is an unremarkable person that was able to break his limiter through sheer determination in exchange of becoming bald and being alienated from humanity.
  • What an Idiot: Who in the Hero Assocation thought it would be a good idea to release a Hero Catalogue to the public that not only reveals the locations of where the heroes are but also where they are usually seen? Why would they have entries about their "secret" moves? Did it ever occur to them that villains, like Garou, might also look through the catalogue?
  • The Woobie:
    • Saitama himself. He doesn't really act like one, but it's clear that his story-breaking powers have taken their toll. It's first evidenced in earlier chapters when he reflects on how every fight is boring and how even with his deeds, no one recognizes him. Later on, during his fight with Boros, Boros has a Not So Different moment with Saitama, claiming how he himself was the strongest person on his own planet, to the point he searched the universe for a worthy opponent because he wasn't able to take any pleasure in fighting any more. His final words to Saitama hit home, when he acknowledges the pain that comes with it and how they couldn't have a proper fight with our hero holding back. Saitama simply walks away without any words and a sad look.
    • Blizzard, a woman whose innate talents made her believe she was destined for great things. But her sister is Tornado, who is the second strongest hero on the planet and crushed Blizzard's self-esteem, making her believe she could never be anything more than second best. Furthermore, she was picked on as a kid for having her powers in the first place and her sister protecting her only alienated her further, leading Blizzard to resent her sister.
    • In terms of Jerkass Woobie, Tornado, who was taken from her family at a young age and used as a guinea pig for years because of her psychic powers. She was even isolated from the outside and denied any contact with her parents or sister. Eventually she stopped using her powers out of spite, but it only led to her being thrown in a cell until she started using them again. Even when an experimental creature went on a rampage, Tornado still didn't use them and was only saved by Blast stepping in to kill the monster, after which he told her not to expect someone to come save her every time. It led to Tornado's current worldview, being bitter at the world and believing that she can only rely on herself and that connection to others and coexistence are pointless. It also led to her being overprotective of Blizzard which of course has led to their strained relationship, Tornado being a meddlesome, stifling control freak in Blizzard's life who thinks she knows what's best for Blizzard. All in all, Tornado is a giant bag of issues due to severely traumatic experiences as a child which could have been avoided if someone had shown her basic decency.
