History Trivia / OnePunchMan

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

** [[Creator/ToshiyukiMorikawa Boros]], [[Creator/KosukeToriumi Flashy Flash]], [[Creator/HirokiYasumoto King]], [[Creator/MiyukiSawashiro Mosquito Girl]], [[Creator/AoiYuuki Tatsumaki]], [[Creator/YuuichiNakamura Mumen Rider]], [[Creator/WataruHatano Metal Bat]], [[Creator/YujiUeda Watchdog Man]] and [[Creator/KazuhiroYamaji Silverfang]] are [[Franchise/StreetFighter Ryu, Nash, Guile, Cammy, Menat, Fei-Long, Rufus, Blanka and G]].

** [[Creator/TakahiroSakurai Zombieman]], [[Creator/KatsuyukiKonishi Tanktop Master]],[[Creator/TesshoGenda Doctor Bofoy]], [[Creator/TakehitoKoyasu Gyoro Gyoro]] and [[Creator/RyuseiNakao Vaccineman]] are [[Manga/SaintSeiya Shiryu, Ikki, Aldebaran, Radhamanthys and Isaac]].

*** The Alien Conquerors arc had multiple redraws. Originally Boros had a much different design, appearing less like an alien and more like a generic one-eyed {{Bishonen}} in demonic black armor. Later, during his fight with Saitama, Boros broke off one of the ship's fins and threw it at Saitama, nearly bisecting the entire spacecraft in the process. This was all redrawn, making him look more alien and swapping out the fin-toss for the moon-kick. There was also a plan for a flipbook animation of Bang hurtling through rubble after being hit by Melzargard, though it never got past the draft phase.
*** Chapter 71 included a panel showing Gouketsu's original design, which was much more ogre-like. Murata believed Gouketsu would be scarier if he looked more intelligent and [[MonstrosityEqualsWeakness less brutish]], so he redrew it.
*** 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 redraws are ''still'' on-going.

*** Chapters 99-100 were completely redrawn for several reasons: giving Child Emperor's Brave Giant a more unique design, and slightly changing how the fight with Phoenix Man flowed. However, even that wasn't enough for the perfectionist Murata...
*** Chapters 99-100 were redrawn ''again'' for the volume release, and this time ''completely'' revamped. Now the fight includes appearances from Saitama, Orochi, and Zombieman, gives Phoenix Man some creative new transformations and powers, and most importantly, lets Phoenix Man ''survive'' the encounter instead of being killed. Additionally, the entire tone of the fight is much more energetic and comedic, instead of being dire and tense like the original, which gives the audience a break from the [[DarknessInducedAudienceApathy constant coolness]].
*** Chapter 101 was redrawn to include an encounter between Zombieman and two Monster Association-made robots based on the captured Metal Knight drone. This was likely to give a bigger payoff to the scene where Child Emperor ponders the status of Metal Knight's drone.
*** Chapter 103 was redrawn for the volume to {{Retcon}} Sweet Mask killing the Narinki Squad, due to the fact that killing brainwashed humans would be much more controversial in-universe [[WhatMeasureIsANonHuman than killing monsters]]. Instead, Atomic Samurai's disciples keep him in check and Sweet Mask spares them.
*** Murata wasn't satisfied with how chapters 122-124 flowed, so he revised it. He made the S-Class narration more similar to the webcomic and led into it by introducing Manako and her fear of the S-Class Flashy Flash.

* 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 fairly easily destroy the entire universe with only his punches. No records of ONE saying this exist.

** [[Creator/MinamiTakayama Child Emperor]] and [[Creator/RikiyaKoyama Deep Sea King]] are [[Manga/DetectiveConan Conan and Kogoro]].

** [[Creator/KatsuyukiKonishi Tanktop Master]], [[Creator/TakehitoKoyasu Gyoro Gyoro]], [[Creator/TomokazuSeki Stinger]] and [[Creator/UnshoIshizuka Asura Rhino]] are [[VideoGame/FistOfTheNorthStarKensRage Kenshiro, Rei, Toki and Kaioh]].

*** [[Creator/WataruHatano Metal Bat]] is Hitoshi Shinsou.

** Franchise/ShinMegamiTenseiPersona have many voice actors:

*** Chris Tergliafera (voice of G4, Tank-Top Tiger, and Heavy Kong) is Mohammed Avdol.

*** Jason Marnocha (voice of Hedro-Jellyfish and Monster King Orochi) is Keicho Nijimura.

*** Brook Chalmers (voice of Bomb) is Polpo.

*** Ben Diskin (voice of Ground Dragon) is Younger Joseph Joestar.

*** Joe Zieja (voice of Awakened Cockroach, Saturn Man, and Butterfly DX) is Oingo.

** 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 in order to pave way for the future, or just because Murata is dissatisfied with how his art turned out. Some notable instances include:
*** Chapter 35 had a scene planned where Boros threw a giant pillar at Saitama during their fight. However, it was redrawn and updated online so quickly that no one's sure what would've happened afterwards.
*** Chapter 71 was slightly redrawn to make Gouketsu's design less ogre-like, since Murata believed Gouketsu would be scarier if he looked more intelligent and [[MonstrosityEqualsWeakness less brutish]].

* TroubledProduction: While season two of the anime didn't turn out completely terrible, many fans were disappointed by its animation, sound direction, and pacing. A lot of this was due to the studio change forcing JC Staff to suddenly stuff ''One-Punch Man'' in between several other shows that were also in the works, leading to a lot of priorities changing and production being rushed. If one is to look at JC Staff's other works at the time such as ''Manga/ACertainScientificRailgun'', the production is much cleaner and the animation much prettier.

*** Chapter 34 originally featured Saitama vs. Geryuganshoop directly in Boros' throne room, like in the webcomic, but it was moved locations to a surveillance room elsewhere for the volume and the anime adaptation.

*** Chapter 102 was redrawn to extend Iaian, Bushidrill, and Okamaitachi's fight with Do-S and the Narinki Squad.

** As of manga chapter 109, 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.
