Line #73 YMMV/OnePunchMan


1	----
2
3	* AccidentalInnuendo:
4	** Chapter 89 of the manga:
5	---> '''Genos''': What do you want with Sensei's meat?\
6	'''Fubuki''': Demon Cyborg, Genos... are you truly satisfied under that man?
7	** Chapter 168 has Genos ramming Saitama to cheer his return, with rather specific place Genos [[https://cdn.readdetectiveconan.com/file/mangap/3262/10168000/71.jpeg decided to hit.]]
8	* AdaptationDisplacement: Most people would be more familiar with the anime than the manga, and there are certainly fewer people familiar with the webcomic than the former.
9	* AlternativeCharacterInterpretation: Is Saitama's "being a hero is just my hobby" thing him playing off a genuine desire to help as IWasJustPassingThrough, or does he genuinely not care 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 CrapsackWorld and Saitama as someone who genuinely doesn't really think or care about the horrific damage caused by the constant monster attacks he faces as long as he gets good fights out of it.
10	** During the fight with Garou the manga would point toward the former interpretation. Saitama seems to want to help people, but not being good at it, complaining he lacks the "instinct" and arrives too late (comparing himself to King and even Garou himself, who in the end turn out to always be exactly where they are most needed to help). It helps that Saitama is shown engaging in heroic behavior that doesn't involve just beating the opponent, like making Child Emperor see through Phoenix Man's manipulation or reassuring Tareo he won't harm Garou and trying to redeem him.
11	* AngstWhatAngst: Saitama is pretty unfazed by the unwarranted hate mail he gets.
12	* AntiClimaxBoss: Gouketsu gets a ''lot'' of build-up in the Super Fight Arc. He beats Genos, martial arts champion Suiryu and a monsterized Bakuzan without even trying. Genos, one of the few people who knows Saitama's real strength, says he sensed an unfathomable amount of power from Gouketsu in their short fight, similar to Saitama, and believes only a quick ambush by Saitama ''and'' the S-Class heroes could safely defeat him. When Saitama goes to face him alone, Suiryu begs him not to go, and when Saitama leaves, Suriyu curses himself for not being able to stop his savior from meeting certain death. [[spoiler:And then Saitama casually obliterates Gouketsu (off-screen no less), just like nearly every opponent he faces. When asked if he was strong, Saitama says he couldn't tell, because Gouketsu didn't last long enough to make an impression.]]
13	* {{Applicability}}: Creator/BillBurr mentioned in [[https://www.youtube.com/watch?v=r4WQal7L2Cw&ab_channel=BillBurr one of his podcasts]] that ''One-Punch Man'' could be read as a commentary on modern Japan, with Saitama being the everyman who beats up villains that symbolize what's wrong with society.
14	* ArcFatigue:
15	** The martial-arts TournamentArc that lasted from Chapters 58 to 71 in the manga ended up being quite fatiguing for some readers, particularly with ONE and Murata's long pauses, not to mention the focus was on a massive monster breakout that occurred during the tournament that resulted in many one-off heroes battling the monsters, rather than on Saitama’s arc. As a result, many felt that the arc was detracting from the central plot. It also doesn't help that the arc can be seen as "{{Filler}}" [[note]]The tournament arc was ONE's idea, so it's technically canon[[/note]] for being smack dab in the middle of the ongoing "Hero Hunter Garou Arc", which is a sore spot for the fans that wished to finally see the Garou storyline conclude.
16	** The manga's version of the Monster Association Arc was turned into an ''extremely'' long arc due to the many additions to the story, which is not helped by a somewhat [[ScheduleSlip inconsistent publishing schedule and highly varying page counts for chapters (usually from 15 to 80 pages)]] The [[https://onepunchman.fandom.com/wiki/Monster_Association_Arc#Trivia wiki]] lists it beginning at Chapter 78, which was published in 2017. It's not until ''mid-2022'', over seventy chapters later, that the arc finally reaches its conclusion.
17	*** The attack on the Monster Association's hideout gets this from some readers due to excessive {{Padding}}. This mostly stems from the plot falling to a snail's pace because of the number of chapters that Murata spent showing off new, or extended, fights between the heroes and low-tier monsters that weren't there within ONE's original comic. As a result, there isn't much storytelling throughout these chapters other than showing off the powers of the heroes. Some of the extended fights, such as Child Emperor vs. [[BaseBreakingCharacter Phoenix Man]], and the Heroes vs. a combined Psykos/Orochi, received the most backlash due to their length or redrawing them again.
18	*** The waiting for this arc to finally finish only gets worse due to Murata going back and making a bunch of revisions to previous chapters while the arc is ongoing. [[spoiler:For example, Murata originally had Sweet Mask kill a group of human mercenaries, but he eventually goes back to revise said chapter so that the mercenaries [[{{Retcon}} actually live this time around]]. This would lead to later chapters also getting revisions to include new scenes of the mercenaries since it wouldn't make sense for them to just disappear after the retcon]].
19	*** The worst part? An arc took FIVE YEARS to finish, lasted InUniverse for about a WEEK, with most of the story and essential battles happening for one day. Talk about ExtremelyShortTimespan.
20	* ArchivePanic: With how many redraws happened in the Monster Association Arc, it's hard to keep a track on which version is official and which is outdated. The new versions of chapters often don't get translated to other chapters either, which just adds more oil to the fire. The Wiki itself has this problem, as the online chapters differ from volume ones, so many of the latter don't even have their own pages.
21	* AssPull: In chapter 168 of the manga, [[spoiler:Garou has come to realize that his Awakened Form (gifted by God) has caused everyone around him to die due to cosmic radiation, including Tareo. So he uses his powers to {{Time Travel}}, asking Saitama to copy and further improve it because he apparently is capable of replicating all of the latter’s techniques by a ''single glance''. Many fans have criticized the ending of the conflict because not only was it not foreshadowed in the first place, it erases the stakes and {{Character Development}} Saitama and Garou had from previous chapters.]]
22	* SugarWiki/AwesomeArt:
23	** Yusuke Murata's redraw. Just compare ONE's original drawings (which aren't too bad themselves and certainly have a charm) to [[http://i.imgur.com/IUQAKRN.jpg Murata's.]]
24	** The first season of the anime was also brilliantly drawn and animated by the staff at Madhouse Inc., setting a new precedent for animation in anime.
25	* AwesomeEgo: Garou is this way for most of the Human Monster Saga as he continuously beats hero after hero; fans just love his unrepentant evil. [[spoiler:Until Saitama brutally humbles him.]]
26	--> '''Garou''': Stop me if you can! Until then, I'll stay this cocky!
27	* SugarWiki/AwesomeMusic: [[AwesomeMusic/OnePunchMan Lots]] in both Madhouse and J.C. Staff's seasons.
28	* AwesomenessWithdrawal: 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 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..... [[http://www.gamespot.com/articles/one-punch-man-season-two-confirmed/1100-6443906/?ftag=GSS-05-10aaa0a Subversion confirmed!]]
29	* BaseBreakingCharacter:
30	** Saitama himself. His main gag, the gag that is the manga's title even, is either a side-splittingly hilarious exaggeration of one of Shonen's key tropes or it overstays its welcome (the fact that internet trolls have run it into the ground ''has not'' helped at all). The caped baldy's constant "meh" attitude at everything thanks to said main gag is also either very funny or annoying. Part of the problem is that it's become fairly unclear how much of Saitama's absurd strength is parody and how much of it is being played seriously, again its split down the middle whether or not explanations for Saitama's "power level" make the story better or not.
31	*** Is Saitama the most entertaining or the most boring part of the story? This is a fairly heated side debate that's come about from the increased focus on side characters in the manga adaptation of the webcomic. For every fan that loves Saitama and wants to see him more and more, there's another who would prefer if Caped Baldy stepped aside so some fan favorites could get more page time.
32	** Genos. Although no one really ''hates'' him, there are some fans who find his character rather boring or at the very least uninteresting compared to Saitama, who [[OvershadowedByAwesome constantly overshadows him in battle.]] The fact that he [[MemeticLoser never seems to win any of the fights he's in]] adds to this. However, others like him for his cool fight scenes, being TheComicallySerious, and actually displaying more emotion than Saitama.
33	** Puri-Puri-Prisoner. Many fans got turned off by him, due to being a hero who cannot help himself from [[PrisonRape having his way with men.]] Some think he's still hilarious and an entertaining character but others, especially some of the LGBT fanbase, think he should be cut off from the story due to being a {{Bara}} [[NakedPeopleAreFunny caricature]] on top of the previous issue's [[AllGaysArePromiscuous unfortunate and offensive stereotype]].
34	** Phoenix Man. Suddenly, a mid-level Mook is [[spoiler:given a power boost that makes him rival the very leaders of the Monster Association themselves?]] Some fans find him [[ShockingMoments a welcome surprise]] that spices up the story and gives Child Emperor a real challenge to show off his skills, while others feel he steals the thunder of the soon-to-be-introduced cadres and slows down the story too much. Phoenix Man wasn't like this in the original webcomic either, which of course grinds the gears of all webcomic purists.
35	*** Nowadays, Phoenix Man doesn't get a flac for his expansion, which is actually often praised, but the redrawn version of him and his fight. Some feel the "official" version makes more sense for Child Emperor development, while other critique Phoenix Man's BadassDecay, with the battle mostly [[PlayedForLaughs being joke heavy]], especially by Saitama who was for many an unnecessary addition.
36	* BrokenBase:
37	** The fandom is pretty split between preferring ONE's original work and Murata's redrawn version, to say the least. Things got worse during Monster Assocation arc, and how [[ArcFatigue really long it was]].
38	** Naturally, the English 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 it's a perfect match with Creator/KaitoIshikawa and fits his serious militaristic personality while others find that his voice is incredibly forced and doesn't sound natural at all.
39	** Whether Tatsumaki wears underwear [[GoingCommando or not]]. No, really. Many fans think that she wears very thin thongs, while others, as seen from many scenes which show her buttcheeks and buttcrack, insist that she wears nothing down there. Chapter 181 of the manga and chapter 79 of webcomic would both reveal that she does wear underwear.
40	** Season 2's presentation has been much discussed. Not only did Creator/JCStaff make stylistic choices such as using [[PastelChalkedFreezeFrame "dezaki" frames]] (which are actually very much praised in ONE's other work ''Manga/MobPsycho100'') and CG animation that clash with the first season, but the production in general has brought debates if JC Staff's animation is either not as good as {{Creator/Madhouse}} or just flat out incompetent even for ''their'' standards. Likewise, the sound design by Yoshikazu Iwanami -- does it capture the feel of the manga enough? Or is it just too much like his work on previous efforts such as ''Anime/Berserk2016'' or ''Manga/JoJosBizarreAdventure''. This is not helped by the fact that they had 6 months to make 12 episodes and kept everything in house (except for freelancers) for the sake of consistency. For reference, well made anime give studios 2-3 months ''per episode''. JC got a sixth of that time.
41	** Creator/{{Sony}}'s announcement of a LiveActionAdaptation has raised many eyebrows. A vocal majority have already declared it a lost cause due to the mediocre track record of Hollywood anime adaptations in the past, while other fans are cautiously optimistic and willing to give it a chance. One thing can be agreed on: everyone is concerned.
42	** In large part thanks to the manga, anime, and different guide books all saying different things about Boros and his Collapsing Star Roaring Cannon, there have been endless debates over how strong Boros truly is and whether he's a planet-buster, star-buster, continent-buster, or just simply a planetary surface wiper. The fact that we never see the full extent of what his Collapsing Star Roaring Cannon can do before it gets pulverized by Saitama only adds more fuel to the flames.
43	** Purists have issues with the anime and manga. Webcomic purists get annoyed by the manga and anime. Manga purists get annoyed by the anime. For example, webcomic purists don't like Orochi. As for the anime, the manga clearly shows that Seaking was still alive and conscious enough after Saitama's punch to look down at his fatal injury in a ThisCannotBe reaction shot; in Season 1 of the anime, his eye is hanging out and he has dead fish face. Seaking was such a {{Jerkass}} that some fans were disappointed that he didn't live long enough to have regrets like in the manga. In Season 2, several heroes were excluded from the 100 Eyes Octopus fight that were in the manga such as Red Muffler and Bones. While these are small time characters, each hero is usually a send up to some of the most popular manga, anime, TV shows, etc. in history leaving certain fans put out. Plus there was no good reason for them to not at least be present besides taking shortcuts on animation.
44	* CatharsisFactor:
45	** After he [[CurbStompBattle gave several heroes the fight of their lives]], sadistically attempted to devour several innocent civilians, and boasted about being the WorldsStrongestMan, it can be rather satisfying to see Saitama prove Deep Sea King dead wrong by using his [[SignatureMove signature one-punch]] to quickly end his life.
46	** After [[MemeticLoser becoming a meme for never winning a fight]] and usually ending up in pieces as a set-up for stronger heroes, Genos [[ThrowTheDogABone gets some vindication]] once he joins the fight against the monster association. Not only does he [[TookALevelInBadass showcase his improvements]] by swiftly eliminating G5, he then becomes an active player in the battle against [[spoiler:Psychos/Orochi]] and instrumental for the victory and finishing a major fight while still standing.
47	* ClicheStorm: Well, it was created as a parody of shounen and superhero tropes in general.[[Administrivia/TropesAreTools It's part of the charm.]]
48	* CommonKnowledge:
49	** Madhouse is exclusively given credit and praise for animating Season 1, particularly after JC Staff was announced to be animating Season 2, and only intensified when the latter season aired to poor reception. While Madhouse was ''officially'' the studio that animated Season 1, much of the animation wasn't actually done in-house. Many of the best-animated scenes in Season 1 were done by animators from Creator/StudioBones, who worked under aliases (most notably, [[https://www.sakugabooru.com/post/show/23510 Yutaka Nakamura]], who went [[UncreditedRole uncredited outright]]). The [[https://www.sakugabooru.com/post?tags=arifumi_imai fight]] between Saitama and Genos, which is often used to show the first season's animation quality? Mostly done by an animator (Arifumi Imai) associated with Wit Studio, not Madhouse. While many other notable scenes (such as [[https://www.sakugabooru.com/post/show/17714 Crablante's death]] by Taiki Imamura, or Deep Sea King's [[https://www.sakugabooru.com/post/show/18835 punch]] on Saitama as animated by Bahi JD) were done by freelance animators as a favor to director Shingo Natsume. Madhouse only produced the series and provided the studios used to do in-betweens and paint the scenes (save for the few episodes completely outsourced to Creator/DRMovie in Korea). Possibly, even Madhouse itself wouldn't have been able to match Season 1's quality if they'd done Season 2 since many of the animators from Season 1 are currently at different studios.
50	** It's stated as fact by many online that Season 2 was terrible and had no animation. While it certainly wasn't as [[ToughActToFollow consistently extraordinary as Season 1]] and lacked the all-star line-up of staff that production benefited from, it by no means lacked any good animation at all. In fact, it features more quality action scenes than most other anime done by JC Staff. Just about any scene animated by Kenichiro Aoki [[https://www.sakugabooru.com/post/show/80734 holds]] [[https://www.sakugabooru.com/post/show/105743 up]] [[https://www.sakugabooru.com/post/show/137097 pretty]] [[https://www.sakugabooru.com/post/show/109100 well]] against Season 1, and he did a truly remarkable number of scenes across the season for just one person.
51	** People often draw parallels between the Hero Hunter Garou and the Hero Killer Stain (from ''Manga/MyHeroAcademia''). On the surface, they are quite similar, but there's a tendency to assign Stain's goals -- to purge the streets of unjust heroes -- to Garou, which is inaccurate. While Stain is concerned with good vs. evil, Garou rejects the notion of justice and concerns himself with popular vs. unpopular. He wants to get back at those who are in power. He believes it's unfair how society assigns "heroes" and gives them the ability to do whatever they want, while others are assigned as "villains" or "monsters" and are subjected to the heroes' punishments. To make the popular people of the world feel what it's like to be the unpopular guys for a change, he wants to become the ultimate, unfair monster and turn the tables. [[spoiler:Only it's not actually that, but Garou wants to become the ultimate monster so that it would unite humanity and give birth to the greatest hero]].
52	* CrackShip:
53	** Tatsumaki and Genos have exploded in popularity after the two of them teamed up to bring down Psykorochi, with Tatsumaki genuinely complimenting Genos for fighting off Psykorochi in a BeamOWar using his ten-second SuperMode. She also protects him from falling after he runs out of power and he returns the favor while she's losing consciousness, leading to many seeing this as a fast-developing VitriolicBestBuds relationship ''at the very least.'' It goes up to eleven and beyond when she’s critically injured by Fuhrer Ugly and Genos carries her to safety, PietaPlagiarism style, only for her to wake up sooner than he or Bang expected and jump right back in with them without a single complaint. After that, Genos is the one to save her from Black Sperm’s grasp, and when Genos gets slammed through the ground immediately after, she actually cries out his real name (rather than “Demon Cyborg”) and there is visible worry on her face -- and then there’s the casual yet friendly banter and the BackToBackBadasses moment that follows. All of this occurs in just a few chapters and shows extreme CharacterDevelopment in their views on each other to the point where it’s extremely debatable whether this even counts as a CrackShip anymore.
54	** There's a surprising amount of Garou x Fubuki fanart out there, despite their only interaction being [[spoiler:a webcomic-only scene of Garou striking fear in her heart as he first appears as a monster.]]
55	* CrossesTheLineTwice: Puri-Puri-Prisoner is intended to be this, what with being a gay {{Bara}} caricature who engages in regular PrisonRape and yet is still portrayed as a heroic character. [[BaseBreakingCharacter The fandom is divided on whether he crosses the line once, twice, or three times.]]
56	* DracoInLeatherPants:
57	** 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 PetTheDog moments, they only occurred in an anime-only OVA.
58	** Garou can get this treatment either due to his FreudianExcuse of being bullied as kid by the local popular kid, some of the heroes being jerks who are [[OnlyInItForTheMoney obsessed with fame and fortune]], his PetTheDog moments towards Tareo, or that he's a [[spoiler:WellIntentionedExtremist that aims to unite the world through fear]]. But among the heroes he beat, he also beat up genuinely heroic ones such as Mumen Rider, after [[NoGoodDeedGoesUnpunished he protected him against Tanktop Master no less]], and while some of the heroes are jerks, he had caused significantly more damage in his actions than any of them, such as [[FridgeHorror potentially causing indirect civilians' deaths as the heroes can't fight off the monsters due to being hospitalized]], Hero Assocation's reception becoming worse and many of their members retiring and [[spoiler:his plans are deconstructed by [[InvincibleHero Saitama]] who notes his plan could only work by defeating him.]]
59	** On the good side, psychic sisters Tatsumaki or Fubuki can have their actions or abrasive qualities overlooked or justified that some other characters won't get, due to them being MsFanservice combined with the manga's SugarWiki/AwesomeArt, as well as their FreudianExcuse of Tatsumaki being sold out as a kid or Fubuki living under her sister's shadow.
60	* EnsembleDarkhorse:
61	** Mumen Rider only has a significant role in one of the story's arcs but has gained a lot of fans, particularly after standing up to the Deep Sea King.
62	** Mosquito Girl managed to place 9th in the character poll, despite only appearing for two chapters. Much like Fubuki, a lot of popularity is owed to her attractive design ([[CuteMonsterGirl for a woman that's part mosquito]]) and fanservice factor.
63	** Similar to Mosquito Girl above, Zombieman managed to come in at 7th place in the character poll despite his only appearance in the series at the time being little more than a cameo.
64	** Captain Mizuki got some attention for being an adorable AmazonianBeauty with an interesting fighting style based on Olympic events. Even before that, her AmazonianBeauty traits gave her many fanarts and PerverseSexualLust factors.
65	** Deep Sea King, due to being one of the most [[ForTheEvulz villainous monsters]] thus far, his ridiculous yet intimidating presence and providing a few [[SignatureScene Signature Scenes]].
66	** Boros is quite popular with the fans for the following reasons: He's the first one to somewhat match Saitama in a fight; his BloodKnight and AffablyEvil personality is likeable; he [[GracefulLoser accepts]] his demise [[GoOutWithASmile peacefully]], and is actually quite an attractive villain, despite -- or maybe even because of -- him having [[{{Cyclops}} only one eye.]] He is also one of the few villains that respect Saitama. It's not uncommon to find fanart of him and Saitama together.
67	** Many of the members of the Monster Association:
68	*** Psykos is well-liked for her evil cunning, her connection to [[spoiler:Fubuki]], and her…[[MsFanservice other assets]].
69	*** Black Sperm's bizarre design and impressive powers quickly made him a fan favorite. [[spoiler:The fact that he manages to survive the Monster Association war to stick around with Forte and Butterfly DX helps.]]
70	*** Orochi's battles have some of Murata's best-looking panels in the Monster Association arc, making him an audience-pleaser every time he appears.
71	* EpilepticTrees:
72	** 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.
73	** Like how Saitama lost all his hair once he acheived his absurd strength, fans like to speculate that Tatsumaki's short height and small body is caused by her having incredibly powerful psychic abilities.
74	** Who Blast actually is. [[spoiler: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''.]] [[spoiler:Subverted when Blast makes a cameo when he meets Saitama and Flashy Flash during the Monster Association Arc. It is implied that Blast is on a mission to stop "God" and collects God's mysterious cubes, keeping them out of reach.]]
75	** Who [[spoiler:the entity Homeless Emperor calls "God"]] is and what plans they have in store.
76	** With {{Word of God}} saying that both Boros and Orochi are above Dragon but under God, people have been speculating who will be the God-tier monster that will inevitably face Saitama in the future.
77	* EvilIsCool:
78	** Garou has a sizeable fanbase for his cool fight scenes and AntiVillain tendencies. [[spoiler:Ironic, considering how bad he is at being evil as Saitama points out]].
79	** Lord Boros can also qualify thanks to his unique design and transformations as well as his massive ship. It certainly doesn't hurt that he's the first villain to [[VillainRespect treat Saitama with respect]] and [[spoiler:[[NoSell doesn't go down after just one punch!]]]]
80	* FandomEnragingMisconception: Fans of American comic book superheroes will get annoyed at the less informed reader of ''One Punch Man'', since while it parodies certain aspects of the Superhero genre, ''One Punch Man'' is more of a parody of the Japanese superhero tropes. This gets especially annoying when some fans proclaim that heroes like Franchise/{{Superman}} [[TheCape and similars]] should be more like Saitama or that the latter is the best example of the former, which will annoy fans.
81	* FandomRivalry:
82	** With ''Franchise/DragonBall''. 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 (such as Vaccineman and Boros). Still, that doesn't stop fans from comparing who is stronger of the two. ''Anime/DragonBallSuper'' 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 animations in the industry thanks to Creator/{{Madhouse}}. ''Dragon Ball'' fans were quick to reply that the animation of ''One Punch Man'' would naturally be better since the budget only had to satisfy a dozen episodes, while the animation budget behind ''Super'' had to continue indefinitely.
83	** A similar example with Franchise/{{Superman}}, probably as an extension/consequence of the ongoing rivalry with Goku. While this particular rivalry can get nasty since both fans tend to use the no-limit fallacy when discussing who's stronger than who, [[BerserkButton what really ticks off Supes's fans]] is when discussing who is the best character in terms of characterization and heroism. It doesn't help that Superman fans have been having some [[Film/ManOfSteel controversial]] [[Film/BatmanVSupermanDawnOfJustice movies]] where [[AntiHero Superman characterization is less than stellar in their eyes.]]
84	** ''Manga/MyHeroAcademia'' is also victim to this, due to fans unfairly comparing it to this, and some even going so far as to call it a rip-off, even though there have been other [[Anime/TigerAndBunny superhero-themed]] [[Manga/{{Zetman}} anime and manga]] [[Manga/{{Kinnikuman}} before]].
85	** A much smaller rivalry has developed with the [[CultClassic niche but dedicated]] fandom for ''Anime/ConcreteRevolutioChoujinGensou'' 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.
86	* FanNickname:
87	** "Fubooty" for Fubuki, [[MsFanservice for obvious reasons.]]
88	** Saitama has been affectionately called by the fandom as "Egg" thanks to his simplistic designs.
89	** Speed-o'-Sound Sonic, however, is referred to by the fandom as "[[StupidSexyFlanders Stupid Sexy Sonic]]".
90	** Genos meanwhile is called by fans as "Toaster".
91	** Vaccine Man is "Purple Piccolo" thanks to his similarities with [[Franchise/DragonBall Piccolo]]. And then the dub ascended it by actually casting [[Creator/ChristopherSabat Piccolo's voice actor]] as Vaccine Man.
92	** Mumen Rider has been dubbed "Bike Man" in certain parts of the fandom.
93	** Some of Garou's upgrades have been nicknamed for convenience, like "Spiral Garou" for the stage that has him [[spoiler:defeating Superalloy Blackluster.]]
94	** Manako, the monster who guides Flashy Flash and Saitama through the Monster Association base, was nicknamed [[WesternAnimation/MonstersInc "Mike Wazowski"]] before her [[FemaleMonsterSurprise gender reveal]].
95	** King has been christened "''One-Stare Man''" by the fandom, on the courtesy of actually ''staring'' a monster to death in the span of seconds and nothing else. Other names cropping up for him are "''One-Gaze Man''" and "''No-Punch Man''" for the same feat.
96	** [[spoiler:Psykos and Orochi's fused form has been nicknamed "Psykorochi", or some variations of it like "Psyrochi".]]
97	* {{Fanon}}:
98	** Garou's [[spoiler:horned monster form was named "Awakened Garou"]] by the fans, but has yet to be officially referred to as such.
99	** Many theorize that Garou was the destined opponent Boros was supposed to face since [[spoiler:his awakened form is the only other character in the series to last as long against Saitama as he did.]]
100	** While started out as a meme, eventually some fans believe that [[spoiler:King]] does have superpower on his own, with the most common one being his extreme luck to [[ActionSurvivor survive even the most dangerous situations]], [[DoesNotKnowHisOwnStrength even if he isn't aware of it]]. Considering that the setting is a CrapsackWorld where [[AMillionIsAStatistic normal humans can die easily in large number without any fanfare]], there's no way [[spoiler:King]] can survive disasters after disasters without any innate superpower if he's just a regular man, which makes this theory rather believable.
101	* FoeYayShipping: Garou and Metal Bat have quite a lot of shipping in the fandom after their fight in Chapter 57. The rule still stands: if two pretty anime men have a grueling battle, they will be shipped together.
102	* FriendlyFandoms:
103	** There's been quite a few people that have noticed how much the series has in common with ''ComicBook/{{Empowered}}'', what with all the superhero parody, kooky powers and supposed "loser" main protagonist. Not to mention [[CerebusSyndrome that when it stops being funny, it REALLY stops being funny]].
104	** 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).
105	** With ''VideoGame/Fallout4'', 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.
106	** Obviously one with ''Webcomic/MobPsycho100'' due to both works sharing the same creator (ONE).
107	** With ''Manga/MyHeroAcademia'' because of how both series are Japanese takes on the Western superhero genre. This has created a significant overlap in the fandoms rather than a rivalry. The fact that ''One-Punch Man'' is a seinen with a much older target demographic and more adult humor than ''My Hero Academia'' helps. Heck, it's to the point where some jokingly suggest that ''One-Punch Man'' is a DistantFinale for ''My Hero Academia'', with Saitama being the final[=/=]current user of One For All.
108	* GeniusBonus:
109	** The [[https://static.tvtropes.org/pmwiki/pub/images/vlcsnap_2016_01_19_00h06m38s248.png Tree of Evolution]] shown behind Dr. Genus in Episode 3 is Ernst Haeckel's Tree of Life.
110	** Why is Mosquito Girl a female? Because only female mosquitoes drink blood. That being said this applies [[{{Squick}} only when they're pregnant]], but still suits her given her reliance on her "babies".
111	** During Garou and Suiryu's online battle in an OVA, Suiryu has several moves reminiscent of Drunken Style martial arts. This is because Suiryu was originally planned to use Drunken Style, but it was changed to the fictional Void Fist.
112	** When Tatsumaki rescues Child Emperor with one of her barriers, she makes sure to keep holes in the bottom to let the water inside pour out. She even adds a hole at the top of the barrier to avoid the [[https://www.stevespanglerscience.com/lab/experiments/floating-water-mystery/ floating water]] effect -- air needs to be able to enter the barrier in order for the water to pour out; if all the holes point downwards that becomes difficult or even impossible.
113	* GrowingTheBeard: For fans not entirely sold on the series beforehand, due to seeing little plot to help support the SugarWiki/AwesomeArt and comedy, the Boros arc and the succeeding chapters act as this since it's where the focus starts shifting from Saitama to other characters to help further flesh out the world, as well as being the point in the series where it became DarkerAndEdgier.
114	* HarsherInHindsight: One of the manga covers has the text "Being adult is looking good in black", featuring several characters with cool clothes. It becomes this when you realise that around that time, Murata's father died.
115	* HesJustHiding: Mosquito Girl, [[ATwinkleInTheSky having merely been sent flying]] by Saitama's swat, when the monsters he hits usually end up in LudicrousGibs (even the bloody smear she leaves on a building in the anime can be explained away as the result of her blood sack rupturing on impact). It doesn't hurt that Murata has published [[https://pbs.twimg.com/media/Ce7aWy1VAAA6LDV.jpg:large drawings 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.[[spoiler:Eventually she came back in chapter 190.]]
116	* HilariousInHindsight:
117	** Creator/YuuichiNakamura's role as [[BadassNormal Licenseless Rider]] is pretty hilarious if you take into account he's the Japanese dub voice of '''ComicBook/CaptainAmerica''' in the ''Franchise/MarvelCinematicUniverse''.
118	*** On that note, Nakamura also goes to voice another character named [[Manga/JujutsuKaisen Satoru]], but this time he gets to become WorldsStrongestMan instead.
119	** The same goes for Creator/HirokiYasumoto (King), which is the Japanese dub voice of ''Film/{{Aquaman\|2018}}''.
120	** The fact that there's a powerless bike-themed superhero constantly getting OvershadowedByAwesome, and it isn't [[Series/ThatMitchellAndWebbLook The Bmx Bandit.]]
121	** Creator/KenjiroTsuda (Atomic Samurai) is the Japanese dub voice of [[Film/TheForceAwakens Kylo Ren]], another swordsman, except being evil.
122	** One for the Dub: Remember the time when some ballsy [[{{Website/Reddit}} redditors]] covered the [[https://www.youtube.com/watch?v=Z12IvPBe7o8 OP]], and someone went full LargeHam screaming "'''IT'S BARGAIN DAY AT THE SUPERMARKET!!!'''"? [[spoiler:[=Dub!Saitama=] says the line word for word in episode 3.]]
123	** Licenseless Rider's main concept was a Kamen Rider parody without a license who rode an ordinary bike that he occasionally attacks with. Thanks to ''Series/KamenRiderExAid'', 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.
124	** Pig God's hero name has been slightly modified in the Italian translation of the manga, since translating it literally results in a quite widespread, but also quite blasphemous, exclamation against the Omnipotent.
125	** Given the rivalry between ''One Punch Man'' and Franchise/{{Superman}} fans, it's fairly hilarious that after getting cast as Saitama for the English dub, Creator/MaxMittelman almost immediately followed that up by taking over as one of the primary voice actors for ComicBook/JimmyOlsen, aka Superman's Pal. And then he topped it by going on to voice [[WesternAnimation/DCSuperHeroGirls the Man of Steel himself]].
126	* HypeAversion: 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.
127	* IAmNotShazam: Despite what people may believe, Saitama is not actually called One Punch Man. If anything, he should be called by his hero name: Caped Baldy.
128	* IKnewIt:
129	** Many fans guessed that Sweet Mask [[spoiler:is an Ugmon monster himself]] before the reveal.
130	** It was widely theorized that Orochi [[spoiler:would return after his fight with Saitama]], which he did twenty chapters later.
131	** When [[spoiler:Golden Sperm showed up very early into the Monster Association battle compared to his webcomic counterpart]], fans were quick to guess an even stronger form would be revealed later on. This came true with [[spoiler:Platinum Sperm]].
132	* JerkassWoobie:
133	** Fubuki, a woman whose innate talents made her believe she was destined for great things. But her sister is Tatsumaki, who is the third strongest hero on the planet and crushed Fubuki'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 Fubuki to resent her sister, as well as turning the B-Class of Hero Association into TheDon, purposely DecliningPromotion to feed her InferioritySuperiorityComplex against her sister (though later it's revealed to be her own method to make Tatsumaki regain her trust within allies) to the point of forcing the other heroes to join her Blizzard Group lest she will cripple anyone who resists including Saitama.
134	** Tatsumaki, [[spoiler: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, Tatsumaki 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 Tatsumaki'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 Fubuki which of course has led to their strained relationship, Tatsumaki being a meddlesome, stifling control freak in Fubuki's life who thinks she knows what's best for Fubuki. All in all, Tatsumaki 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.]]
135	** Suiryu. Very much a ArrogantKungFuGuy who also has a philosophy that [[SocialDarwinism the strongest will survive]], [[{{Foreshadowing}} so there's no point of being a hero and rescuing those in danger]] [[TheHedonist and it's better to just enjoy life and having fun with fighting, winning and being the best]]. However, Suiryu suffers such a TraumaCongaLine that it's pretty hard to not at least pity him: [[spoiler:he finally looses in a fight thanks to Saitama, he gets heavily beaten by monster Gouketsu despite the fighter best efforts ''[[FromBadToWorse and]]'' then Bakuzan transformed into monster drives Suiryu into DespairEventHorizon and proceeds to shout for any hero to show up and save him and rest of unconciuos people on the stadium. Thankfully, after all of this, [[BidDamnHeroes Saitama reappears]].]]
136	** Garou. He was bullied by the other kids in school for sympathizing with the monsters on TV shows and for not playing along with their hero games on the playground. When school authorities got involved, he was [[UsefulNotes/VictimBlaming victim-blamed]] for not conforming to the other kids' standards. Because of this, he's always felt like a universally-hated underdog, and it's part of why he goes on his self-destructive crusade to knock heroes down a peg and become the ultimate monster. And despite all of his violence, he never truly intends to kill anyone -- he just wants to give the little guys of the world a chance to get back at their oppressors. Then, it's revealed that [[spoiler:Garou wants to become the ultimate monster so that ''someone else'' can become the ultimate hero in return -- the poor guy wants good in the world, but simply lacks the self-confidence to be a hero himself]]. Makes it hard not to root for him, or at least get him a hug.
137	* JerksAreWorseThanVillains: The villains of the series usually lean into EvilIsCool (Garou, Boros, Phoenix Man), EvilIsHammy (Carnage Kabuto, Deep Sea King), or sexy (Mosquito Girl, [[spoiler:Psykos]]) territories, sometimes combiniation of all these three (Speed-o'-Sound Sonic) or straight up [[WeHardlyKnewYe don't last long enough to give any impression]] (Vaccine Man, Beefcake) usually thanks to Saitama himself. However, there are several loathsome characters on the heroes and citizen sides who are straight up unlikeable, even more than the villains.
138	** Despite being supposedly the "good guys", some of the lower-ranked heroes are unpleasant jerks who like to rookie-crush newbies and even ruin other heroes' reputation. Examples being Tank Top Tiger, who accuses Saitama of being criminal for very filmsy reason[[note]]He pretty much wants to rookie-crush Saitama to make himself look good[[/note]], and fellow Tank Top Black Hole, being UngratefulBastard who blames Saitama for the meteor aftermath and gaslights the citizens to mob-shame him, despite Saitama pretty much saved them from the catastrophe. Unlike higher-ranked heroes, who either have AwesomeEgo or being JerkassWoobie at worst, these heroes are mostly SmallNameBigEgo and have very few redeeming qualities.
139	---> '''Bang''': So they're out to crush a rookie and perform a publicity stunt at the same time. I'd say they've gotten a little greedy. No wonder they can't rise above Class B.
140	** On the citizen's side, there's a foul-mouthed, entitled civilian from the Sea King Arc fan-named "NEET evacuee" who badmouths the heroes for losing against Deep Sea King, and mocks their effort, saying that the monster probably wasn't all that strong if a Class C rookie managed to defeat him. Apparently, it gets so bad that Saitama has to pull ZeroApprovalGambit to save the heroes' reputation. With his rather fitting name for such attitude, said civillian is generally agreed to be even more loathsome than the Deep Sea King himself.
141	** There's also Tacchan, a character from the past, who bullied Garou and is a main cause of the creation of a Hero Hunter. While playing the game of "heroes and monsters", Tacchan jumped off of a high perch and kicked his friend on the back. Garou visibly got concerned and said that doing such things was dangerous, and in response, surprised Tacchan chose to make him his next victim, [[DirtyCoward telling his friends to restrain Garou, while beating him]]. Later, Garou challeged his bully and wanted a payback, and again, Tacchan's friends hold him while the "Justice Man" beat him again. What's worse, [[UsefulNotes/VictimBlaming it was Garou who suffered the punishment]] and not [[KidsAreCruel Tacchan]], who [[KarmaHoudini never got his karma]]. Given how we never hear one mention of him in the modern story, especially in the Hero Association, it can be more than likely assumed that he in fact [[DoomedByCanon failed]] to become a hero like what he so desired to be as a kid.
142	%%** Hero Association has [=McCoy=], an executive who (insert police omake and recent chapter info here)
143	* JustHereForGodzilla: Saitama is what most people know the series for, and people will often watch the show to see his one-punch antics completely unaware of the rapidly-developing plot that lies beneath.
144	* LauncherOfAThousandShips: Saitama. If one looks at fanworks, he's shipped with everyone, with the most popular pairings being with Genos (due to HoYay) and the sisters Fubuki and Tatsumaki (due to interpreting their relationship as BelligerentSexualTension). Not bad for a bald guy.
145	* LoveToHate: Not any of the villains, [[JerksAreWorseThanVillains but rather a particularly foul-mouthed civilian]] from the Sea King Arc, dubbed Frog Lips by fans. A real jerkass who starts bad-mouthing the Hero Association by pointing out a B-Class hero was able to beat the Sea King in one punch while none of the others could, and being quite the UngratefulBastard. He may have only ever shown up once, but few characters are so much fun to loathe.
146	* MemeticBadass: Naturally, as a series parodying various shonen tropes, it has this in spades.
147	** '''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''.
148	** Mumen Rider, oddly enough, despite his [[FailureHero track record]] being the exact opposite, has developed this reputation almost as much as Saitama, but for the exact opposite reasons. He has no powers, he never wins a fight, and he never even slows the villains down -- and he ''[[{{Determinator}} just. Keeps. Coming.]]''
149	** King. After all, he's the strongest man in the world. [[spoiler:Even after he's revealed to have no superpowers at all, this only elevates his badass status to many, such as his extreme luck to [[ActionSurvivor survive even the most dangerous situations]], or the ability to summon Saitama anywhere and anytime.]]
150	** Watchdog Man. 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.
151	** 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 [[GracefulLoser a final chat with his opponent]].
152	** Garou, after [[CurbStompBattle curb-stomping]] [[spoiler:nearly every S-Class hero]].
153	** Phoenix Man, for his [[spoiler:sudden power boost that rivals even the ''Monster Association cadres'']]. Murata has also redrawn Phoenix Man's fight with [[spoiler:Child Emperor]] multiple times, leading to jokes that Phoenix Man's [[spoiler:resurrection]] powers traverse time and space. He even [[{{Rewrite}} brought the Narinki Squad back to life]].
154	** The hot-dog monster that appeared in Volume 10 omake somehow got a reputation of being a god-level threat that could end humanity.
155	** Due to him sharing his initials with [[spoiler:Awakened Garou]], a FanNickname of said character which refers to the time frame he occupies at the end of the Monster Association arc, there are jokes about how Armored Gorilla played a huge role at the end of the Monster Association Arc.
156	** Any objects that are somehow undamaged by Saitama when he hits them, like his alarm clock or table.
157	** The mosquito in Episode 2 is considered as such being the one thing Saitama cannot hit.
158	** On a meta-level, due to him delivering a ton of high-quality artwork updating the manga regularly, many fans will mention how Murata [[TookALevelInBadass broke his limiter]].
159	* MemeticLoser:
160	** Genos has such a reputation of getting trashed by his opponent that anytime he prepares to fight, fans are just counting down to how long he goes before losing at least one limb. Thankfully he becomes MemeticBadass quite a few times in the story, especially in Human Monster Saga.
161	** Atomic Samurai just like the other S-Class heroes is very much well liked, although he has his lesser moments, particularly his fight with Black Sperm and other battles in Monster Association Arc, that managed to give him "Atomic Sandbag" name and reputation, often editing him to the fights where he's beaten like a sandbag.
162	* MisaimedFandom: Due to its very premise, the series attracts lots of attention from "power-scaling" fans who like to debate about who can beat who based on feats, similar to ''Dragon Ball''. This is terribly ironic, as a major theme in the story is that logic can't capture certain forces of nature; the flaws of the hero rankings and monster disaster levels are a clear example. Not only is Saitama's strength incalculable, but everyone else's is too. Characters like King, Black Sperm, Phoenix Man, Garou, and more are constantly overestimated or underestimated by those around them, many fluctuating greatly in strengths and weaknesses across the series. It's like the story ''itself'' is making fun of such calculations.
163	* {{Misblamed}}:
164	** Some people blame Murata for making the story longer in the manga by adding "filler" to the story, such as the Super Fight arc. However, everything added to the manga is either ONE's idea or an idea approved by ONE himself (meaning any kind of "filler" is actually canon). If anyone's to blame, it'd be the original author himself.
165	** There are plenty of fans who claim J.C. Staff is a "bad studio" because of Season 2's poor quality, and believe that Madhouse is a "good studio" in contrast. However, this is disregarding all the talented animators who were commissioned for Season 1 but ''didn't actually work at Madhouse'' at the time. J.C. Staff did indeed drop the ball to some extent, but the real reason it wasn't as good is because it didn't have a dream team of Japan's best animators working on it anymore.
166	* SugarWiki/MostWonderfulSound: Hearing Saitama's punches connecting with some poor monster is ''damn'' satisfying -- the sound effect itself resembles a mixture of gunfire and realistic, meaty impacts with plenty of reverb, sort of like a weightier version of [[Manga/JoJosBizarreAdventureStardustCrusaders Star Platinum's punches]]. Unfortunately, the only time we get to hear it at length is during a fight that turns out to be AllJustADream.
167	* MoralEventHorizon: Several villains cross it over the course of the series with their attacks on cities and civilians, justifying their deaths at the hands of heroes, especially Saitama, but some are more notable than others.
168	** Deep Sea King crosses it when he attacks a little girl with acid just because she was cheering for Genos. Thankfully, [[HeroicSacrifice Genos saves her at cost of destroying most of his body.]]
169	** Boros and his crew cross it when they devastate A-city because the former was looking for a worthy opponent.
170	* {{Narm}}:
171	** King's TheReveal scene is played very seriously in all iterations, and it is indeed very touching... except that anime's version of it is mixed with Genos's fight against the villain G4, making the entire scene feel quite awkward and disorted.
172	** Orochi's voice in the English dub is a growling [[WesternAnimation/InspectorGadget Dr. Claw]]/[[VideoGame/JakAndDaxter Oracle]] voice that... isn't all that intimidating, to say the least.
173	* NarmCharm: Saitama's constantly bored SeenItAll attitude towards the threats he faces, least of all an alien invasion in the Season 1 finale, can seem pretty ridiculous at times. However, given that he is the WorldsStrongestMan who can take down anyone with just [[OneHitKill one punch]] and hasn't been able to face a worthy opponent in years, his attitude actually makes sense. [[RuleOfFunny It helps that it's also pretty hilarious.]]
174	** Saitama's appearance in general is this. He is meant to invoke the UnusuallyUninterestingSight among the more detailed characters, and his design doesn't change much from Webcomic to Manga either, even when other characters undergo significant ArtShift. And yet the series will lose most of its charm if Saitama has the appearance of StockShonenHero or StockLightNovelHero.
175	* OlderThanTheyThink: Due to AdaptationalDisplacement, you'd be forgiven for thinking ''One-Punch Man'' started around 2015; in reality, the original webcomic has been going since 2009.
176	* OneSceneWonder:
177	** This is bound to happen to every MonsterOfTheWeek thanks to being one punched by Saitama. Many of them only appear in one or few chapters, but because of their designs, presence, and lines, they remain well-remembered in fans' minds. Vaccine Man, Crablante, The Brain and Brawn Brothers, and the Subterraneanans are quite iconic, but they all appear only in the first episode of the anime.
178	** An unnamed monster who looks like a CuteMonsterGirl fusion of some sort of cat or zebra with a bell around her neck has noticeably been making the rounds, particularly in the {{NSFW}} area. Not bad considering her only appearance [[spoiler:is being one of the poor {{Mooks}} being [[YouWillBeAssimilated absorbed into Orochi's Heart Element form]]]] (although that might actually explain the abundance of {{NSFW}} art around her).
179	* ParodyDisplacement: In the West, many viewers are completely unaware of Saitama being a parody of ''Literature/{{Anpanman}}''.
180	* PeripheryDemographic: 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.
181	* RescuedFromTheScrappyHeap:
182	** Fans were initially lukewarm towards Monster King Orochi. Being a manga-original creation who was given position over favorites like Black Sperm, on top of having an [[spoiler:initially]] boring design and bland personality, many were disappointed that a perceived DumbMuscle for Gyoro-Gyoro had such an important role. Once Orochi's backstory was revealed and he had his fight with [[spoiler:Garou, revealing a frightening and awe-inspiring transformation and demonstrating abilities like breathing white fire, mastering techniques at a glance, and summoning dragons from his body,]] fan opinions began to change. To top it off, WordOfGod claimed [[spoiler:Saitama wouldn't kill him with one punch]]! Fan respect skyrocketed, even to the point where fans were relieved to see [[spoiler:Orochi's return after his first defeat at the hands of Saitama]].
183	** Waganma has a fitting name, since he's a SpoiledBrat [[UngratefulBastard who's rude to pretty much anyone who tries to save him]], making the entire operation for rescuing him in Monster Association arc feel unnecessary, since some don't even want him to be rescued. Later however, he does begin to feel bad for his actions such as lying that there's other hostage in the base, which doesn't even anger Child Emperor and instead he thanks Waganma for admitting this. After entire arc, [[spoiler:he befriends Tareo and invites him to his house, despite Waganma's earlier mistreatment of him]]. This CharacterDevelopment was enough for many fans to stop hating on the kid at least a little bit.
184	** While Sweet Mask was not outright hated, he was considered a rather bland and obnoxious KnightTemplar {{Bishonen}} hero. However, once his backstory as [[spoiler:an ugly human who became a mysterious being]] was revealed, along with showing more parts of his personality which are [[spoiler:surprisingly noble]]. Fans now appreciate him more and genuinely want to know what will happen to him, [[spoiler:especially since his identity was revealed to the public with Saitama helping him escape and the Neo Heroes hunting him down]].
185	* RootingForTheEmpire:
186	** In a weird sense, 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 the desire to see someone that can be a WorthyOpponent for Saitama. Examples include Sonic, Boros, and Garou.
187	** Played straight at other times, whether it's because the heroes are acting like dicks or the villain/monster is just [[EvilIsCool too cool]]. In particular, webcomic readers hope for a ''real'' threat to appear and beat down the arrogant members of Neo Heroes.
188	** Garou is a lot more sympathetic than Boros and definitely invokes this, especially since most of the battles involving him against the heroes are shown from his perspective such as his battle against eight Pro Heroes hunting him down.
189	* SacredCow:
190	** Season 1 and any arc related to it is this. With its amazing animation, writing, characters, music, etc you will rarely find harsh criticism for this season of the series and if you do, you won't be taken seriously.
191	** On the character's side, despite being a secondary, Mumen Rider is very much well liked for his famous scene in his "battle" with Deep Sea King. Making a statement that you don't find his kind attitude charming or that he deserved to get beaten by Garou ''will'' make the others a bit annoyed, to say it mildly.
192	* SeasonalRot: The second season is considered to be significantly inferior to the first for these reasons:
193	** Season 2 had to deal with a change in animation studios, with J.C. Staff taking over for Madhouse. This resulted in the animation quality taking a nosedive, with the incredibly fluid and immaculately presented action sequences from the first season being replaced by stiff movement and flat composition. While the writing remained relatively untouched, given that the first season was especially praised for its incredible action the downgrade came as a major punch to the gut in the eyes of many fans and critics.
194	** The story had its issues too, in the view of some. The episodic format from the first season were replaced by several season-long arcs (Garou, the Monster Society, the martial arts tournament) that, while more ambitious, [[EndingFatigue started to drag after a while.]] The tournament plot in particular lacked the ridiculous heroes and monsters the show was known for, instead being populated by a lot of guys in identical clothing who all had the same general ArrogantKungFuGuy shtick. The season also spread itself thin over so many characters that there wasn't much room to develop any of them.
195	* ShockingMoments: The series as a whole is full of this, from Saitama punching Vaccine Man in one hit, to [[spoiler: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.]]
196	* SignatureScene:
197	** Saitama's practice bout with Genos as a whole is often cited to show off the series' [[SugarWiki/VisualEffectsOfAwesome animation quality]], and the [[https://www.youtube.com/watch?v=IIkcSu0EH-s Death Punch]] scene tends to be parodied often.
198	** Mumen Rider's HeroicResolve when he takes on the Sea King despite knowing that he can't win. Pretty much everyone agrees that this is the very definition of being a true hero.
199	** Saitama's encounter with Boros, [[spoiler:particularly Saitama's deadpan response [[https://40.media.tumblr.com/99f93f96332bdc206f7b92b300844b4f/tumblr_inline_nyx0y4YAsm1r5ight_540.png when the latter loses his armor]].]] This includes [[https://www.youtube.com/watch?v=_Eqpc7E5tu4 Serious Series -- Serious Punch!]], being an amazing way to finish off the first season.
200	** Garou vs. Tanktop Master and the Tanktopper Army is often cited as a highlight of Season 2, which was regarded as otherwise unremarkable.
201	** Similar to above, Garou's fight with several heroes at the beginning of Monster Assocation's Arc is highly praised, and the episode which it appears is considered the best one from Season 2, with an 8.9 rating on {{Website/IMDb}}.
202	** A lot of Monster Association Arc scenes can be put here, but Saitama's final fight with Garou is by many considered as the most standing out. For manga, [[spoiler:there's [[EnlightenedAntagonist Awakened Garou]]: [[HumanoidAbomination Cosmic Fear Mode form]] being very popular on social media such as {{Platform/TikTok}} or {{Website/YouTube}}]]. For webcomic, [[spoiler:it's Garou's MotiveRant about his [[WellIntentionedExtremist "Absolute Evil" worldview]] and hate towards heroes, and Saitama's KirkSummation pointing out how flawed Garou's idea is]]. For both, [[spoiler:it's Saitama's performing his Serious Series move called "Serious Table Flip" with him rising up the entire ground around him to attack Garou]].
203	* SoOkayItsAverage: The second season of the anime was met with middle-of-the-road reviews from critics. It was praised for its expansions on the ''One-Punch Man'' universe and its attempt to tell a longer and more involved story arc (especially the inclusion of Garou), but the lackluster production was seen as holding it back and limiting its effectiveness. Partially in effect due to ToughActToFollow, considering how well-received the first season was.
204	* SpecialEffectFailure: The anime sometimes places a metallic texture on metal objects such as robots or armor. While the same technique was used in [[https://vignette.wikia.nocookie.net/onepunchman/images/b/bb/Bofoyrobot.png/revision/latest?cb=20160108182502 Season 1]] to great effect, it is used much more often and looks a lot worse in [[https://vignette.wikia.nocookie.net/onepunchman/images/8/81/Atomic_kills_Salamander.png/revision/latest?cb=20191208182602 Season 2]]. This metallic texture was used in a lot of unnecessary places and makes characters such as Genos and Superalloy Darkshine look grimy and overly detailed compared to their Season 1 designs. Fortunately, many scenes were retouched in the Blu-Ray releases to make the textures less gaudy, but they're still very present.
205	* StoicWoobie: Saitama himself. He doesn't really act like it, 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 NotSoDifferentRemark 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 anymore. 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. Later still, after the manga's tournament arc, comes a conversation with King where Saitama finally talks about his growing emotional detachment with someone, his lack of interest in virtually everything except the thrill of combat, but also showing that he may not be completely emotionally numb yet.
206	* TheyChangedItNowItSucks:
207	** Some webcomic-purists disapprove of the changes present in the manga (such as the addition of Super Fight, Orochi or pretty much everything in the Monster Assocation arc), believing ONE's writing shouldn't be tampered with, despite every change is made by ONE himself.
208	** Many were disappointed when the anime did not show the flip-book-like scenes from the digital manga the series is famous for, instead of using the tankobon versions of the scenes.
209	** For Season 2, many weren't happy with the speedy pace of the season which rushes through the story and doesn't allow time for other characters or scenes to really showcase themselves. The Garou vs Metal Bat fight, for instance, is over before it starts and many of the hero-versus-monster bits are shortened. Might borderline on ItsShortSoItSucks.
210	** Older fans are often disappointed by the official Viz English translations of character names, preferring the names from the fan-translations instead. In fact, many fans continue to refer to characters by their fan-translated names, which can cause some confusion when everyone has at least two names (i.e. Fubuki/Blizzard, Superalloy Darkshine/Blackluster, Elder Centipede/Centichoro).
211	* TheyWastedAPerfectlyGoodPlot: Some fans feel that specific chapters before being retconned were better that the official, "canon" version. [[spoiler:In one of the chapters, before it got changed, Saitama stops his fight with Awakened Garou, saying that it won't get them anywhere. They proceed to sit down in a near apartament. Even those who are satisfied with the change say the version before would be quite interesting to read.]]
212	* ToughActToFollow: The first season of the anime was cited as one of the best-animated and funniest shows of 2015, by casual and hardcore anime fans alike. A change of production teams and super-high fan expectations made it hard to follow up such a masterpiece with the second season.
213	* UnpopularPopularCharacter: 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 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.
214	* VanillaProtagonist: 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, and has no other defining features in contrast to the more colorful side characters like Genos. In the webcomic, even his drawing style feeds into this trope because he looks like a stick figure instead of a more detailed form like the other characters. [[spoiler: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 for becoming bald and being alienated from humanity.]]
215	* ViewerGenderConfusion:
216	** Sonic. None of the characters have difficulty telling that he's a guy, which is likely due to [[Creator/YuukiKaji his voice]].
217	** Lightspeed Flash confuses viewers for the same reason as Sonic, what with his flowing blond locks and slender frame.
218	** Okamaitachi, though it's a bit on purpose -- he is a {{Crossdresser}}.
219	** Manako is a female, but [[FemaleMonsterSurprise you wouldn't know that unless she told you]].
220	** A rare example of Viewer Race Confusion is present with Superalloy Darkshine. He has many of the characteristics of a stereotype of an African man, but in a flashback, he is shown to be lighter-skinned; in reality, he just has so much bronzing and spray tan on that he appears black, referencing a real-life UsefulNotes/{{bodybuilding}} practice.
221	* SugarWiki/VisualEffectsOfAwesome: The second season's hand-drawn animation quality definitely suffered, thanks to the sudden and rocky transition to J.C.Staff. However, one thing they did get right was the CG-animated characters, such as Elder Centipede. CG in anime had obtained mixed results throughout most of the 2010s, and it was refreshing to see CG animation that finally didn't clash too much with the traditionally-animated environments and characters.
222	* VocalMinority: The second season had absolutely no shortage of criticism by fans online about the animation quality. But, for all the complaints, it was still easily one of the most popular anime of Spring 2019 despite stiff competition from series such as Manga/DemonSlayerKimetsuNoYaiba and the second half of ''Manga/AttackOnTitan'' Season 3. While many may not have enjoyed it as much as Season 1, many still watched and enjoyed it, with a few scenes being quite popular on social media, just like with Season 1.
