History Trivia / OnePunchMan

*** Possibly the most dramatic divergence occurs in chapter 164 of the manga, which was heavily redrawn just two weeks after its release. In the original version, at the climax of his fight with Saitama, Garou realises how hopelessly outclassed he is and gives up on trying to win, becoming suicidal and launching one last futile attack in the hopes that Saitama will kill him. Saitama effortlessly catches his punch, and realising that Garou seems to have some deep-seated issues surrounding heroes, invites him to sit down and talk things over, culminating in an amusing scene of the two of them sitting around a table, Saitama focusing intently while Garou - still in his hulking monster form - looks a little shy and embarrassed. In the redrawn version, which the rest of the manga follows on from, [[spoiler: instead of becoming suicidal, Garou's resolve endures, and he proclaims that he won't lose to the likes of Saitama...right before he gets punched so hard he flies right out of his monster form. In this moment, God sees an opportunity to use Garou as his avatar, and offers him a power-up. This results in Garou finally achieving his Awakened form, which imbues him with new PersonOfMassDestruction abilities and lets him (''very'' briefly) match Saitama's strength]].

** The French dub casts rapper Orelsan as the voice of Saitama. Outside of acting, his music portfolio is [[ComicsRuleEverythingAroundMe known for carrying some pop-culture referenced songs]], making his role fitting for the character.

** It shares some voice actor as well with Manga/DemonSlayer.

*** [[Creator/Saori Hayami Fubuki]] is Shinobu Kocho.

* FanNickname:
** "Fubooty" for Fubuki, [[MsFanservice for obvious reasons.]]
** Saitama has been affectionately called by the fandom as "Egg" thanks to his simplistic designs.
** Speed-o'-Sound Sonic, however, is referred to by the fandom as "[[StupidSexyFlanders Stupid Sexy Sonic]]".
** Genos meanwhile is called by fans as "Toaster".
** 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.
** Mumen Rider has been dubbed "Bike Man" in certain parts of the fandom.
** Manako, the monster who guides Flashy Flash and Saitama through the Monster Association base, was nicknamed [[WesternAnimation/MonstersInc "Mike Wazowski"]] before her GenderReveal.
** 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.
** [[spoiler: Psykos and Orochi's fused form has been nicknamed Psykorochi.]]

** The French dub casts rapper Orelsan as the voice of Saitama. Outside of acting, his music portfolio is known for carrying some pop-culture referenced songs, making his role fitting for the character.

* CelebrityVoiceActor: In the Latin American Spanish dub, Sonic is voiced by Mexican rock singer Rick Loera.

*** ONE said Tatsumaki would've been able to defeat [[spoiler: Golden Sperm if she hadn't been recently weakened]]. She would probably be able to defeat Mob from ''Manga/MobPsycho100'' as well, but if Mob got serious ONE wouldn't be so sure.

** [[Creator/MinamiTakayama Child Emperor]], [[Creator/RikiyaKoyama Deep Sea King]] and [[Creator/WataruTakagi Hammerhead]] are [[Manga/DetectiveConan Conan, the second Kogoro and Genta, Inspector Takagi and Kamen Yaiba]].

** Vaccineman in the Japanese version is voiced by Creator/RyuseiNakao, who voices Baikinman from ''Franchise/{{Anpanman}}'', the character who Vaccineman took his inspiration for his name from. The dub just cuts straight to the chase and cast [[Franchise/DragonBall Piccolo]] [[Creator/ChristopherSabat himself]].

** Kenichiro Aoki, an animator for season two, is a big fan of ''One-Punch Man'' and [[https://www.sakugabooru.com/post?tags=kenichiro_aoki+one-punch_man_2 it shows]].

** Murata has [[{{Rewrite}} redrawn entire chapters]] on multiple occasions. Usually, the online chapter release and the physical volume release differ in this way - here's a [[https://66.media.tumblr.com/b73226d958aab16393b0ee9c3fddf6a5/tumblr_nwsl8h49xs1sl7gimo1_1280.png great]] [[https://vignette.wikia.nocookie.net/onepunchman/images/6/62/King_face.jpg/revision/latest?cb=20190807175729 example]]. The volumes are considered canon in the end, and they are what the anime adaptation is based on. This is normally to {{Retcon}} old story ideas to pave way for the future, or just because Murata is dissatisfied with how his art turned out. Some notable redraws include:

* TheWikiRule: [[http://onepunchman.wikia.com/wiki/One-Punch_Man_Wiki One Punch Man Wiki]].

* AllStarCast: The voice acting credits is basically a roll call of anime's top Japanese voice actors - even one-episode characters are voiced by heavy hitters such as Creator/MiyukiSawashiro (Mosquito Girl) and Creator/UnshoIshizuka (Asura Rhino).

** The English cast is no slouch, either, bringing together voice actors from not only [[Creator/BangZoomEntertainment Bang Zoom]]'s stable, but also from Texas, including Funimation's Creator/ChristopherSabat and Creator/MikeMcFarland.

** This isn't the first time Creator/JamiesonPrice has been [[VideoGame/BlazBlue an intelligent robot warrior]], though he's upgraded from cyborg to robot drone controlled by scientist.

*** From the same series, Creator/SaoriHayami plays Atalanta, who has similar shades of green hair as Fubuki and also has similar dynamics to Furukawa's character. The main difference being that Achilles has a crush to Atalanta and later develops to a LikeBrotherAndSister relationship (though as of ''[[VideoGame/FateGrandOrder Grand Order]]'', they do seem to have feelings towards each other), while Fubuki develops her respect to Saitama and goes to become VitriolicBestBuds (time will tell over what ONE decides to do with their relationship).

* CreatorsPest: Murata has stated he dislikes Sweet Mask. Because of this, he tries to draw him as handsome as possible in order to get over his feelings.

** Speed-o'-Sound Sonic however, is referred to by the fandom as "[[StupidSexyFlanders Stupid Sexy Sonic]]".
** Genos, meanwhile is called by fans as "Toaster".
** Vaccine Man is dubbed as "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.

* GodNeverSaidThat: There's a rumor floating around that ONE said Saitama's Serious Punch is half the strength of the Big Bang, and that he could easily destroy the entire universe with only his punches. No records of ONE saying this exist.

*** Morikawa voiced as Ryu and Nash in VideoGame/StreetFighterAlpha 3 and Toriumi voiced as Fei-Long. Nakamura voiced as Fei-Long in VideoGame/StreetFighterIV and Toriumi voiced as Nash in VideoGame/StreetFighterV.

*** Cretor/ChrisTergliafera (voice of G4, Tank-Top Tiger, and Heavy Kong) is Mohammed Avdol.

** Originally, Suiryu used Drunken Fist in combat and was Lin-Lin's brother. The Drunken Fist was changed to the fictional Void Fist (a homonym in Japanese), since the style was deemed too comical for intense scenes such as the Gouketsu fight. However the idea of Suiryu having a sister was later repurposed ito a new character called Suiko.

This is normally to {{Retcon}} old story ideas in order to pave way for the future, or just because Murata is dissatisfied with how his art turned out. Some notable redraws include:

*** The series' most infamous redraws have definitely been those done during the Monster Association raid, from Chapters 99 and on. Some notable ones include: retconning Sweet Mask's murder of the Narinki Squad, adding a fight between Zombieman and some Metal Knight-based monster drones, introducing Manako, and redrawing the entire Phoenix Man fight ''twice''. As of writing this, the arc's redraws are ''still'' on-going.

** According to Murata, the energy balls used by Vaccine Man, Homeless Emperor, and Monster!Choze are all made of the same kind of energy.

*** ONE stated [[spoiler: Golden Sperm]] is as powerful as Ossan from ''Makai no Ossan''. Murata said that he's not sure who would win between him and Orochi, since [[spoiler: Golden Sperm]] is much faster but Orochi has greater fighting technique.

* DoingItForTheArt: Pretty much the only reason the first season, an anime with an average budget, has such beautiful animation.
** While the second season's animation suffered a bit due to a studio change and rushed production, some of animator Kenichiro Aoki's best work is in the series just because he loves it.

** Kenichiro Aoki, an animator for season two, is a big fan of One-Punch Man, and it shows in [[https://www.sakugabooru.com/post?tags=kenichiro_aoki+one-punch_man_2 his work]].

* PromotedFanboy: Murata is this in some ways; he loved One-Punch Man before he even met ONE and began working on the redrawn manga.

*** On the Japanes side:

** [[Manga/Haikyuu]] has some of the voice actors:

*** [[Creator/YuuichiNakamura Mumen Rider]] is Film/{{Captain America|TheFirstAvenger}}.

*** [Creator/KoukiUchiyama Melzalgald]] is Tsukishima.
