* ActorAllusion: Creator/YuuAsakawa, who voiced the stoic samurai sword wielder, Sho Tachibana, in ''Shin vs. Neo'' would later go on to voice [[Anime/IkkiTousen Chou'un Shiryuu]], who, like Sho, [[{{Expy}} is also a stoic samurai sword user]].
* ActingForTwo: In ''Getter Robo Daikessen!'', several characters are voiced by the same person.
** Professor Tachibana and General Bat are both voiced by Tomihisa Aso.
** Bob Hosner and Count Rasetsu are both voiced by Akira Murakami.
** Emperor Gore, Professor Lando and John Lambert are all voiced by Kozo Shioya.
* AuthorExistenceFailure: Creator/KenIshikawa. This left Getter Robo Āḥ, the last series chronologically, on a very annoying cliffhanger since the magazine it ran in was cancelled and he was unable to pick it up again before his death.
** Possibly not. The ''Getter Robo Saga'' compilation manga (made while Ishikawa was alive) supposedly has a "revised ending for Getter Robo Āḥ", but few English-speaking fans have been able to read it.
*** The revised ending glosses over the previous cliffhanger and presents an even worse one. [[spoiler: Arc makes it back to Earth somehow, Kamui pulls a coup of the Dinosaur Empire and develops the anti-Getter weapon "Bug", and beats the crap out of Arc. Then Getter Dragon appears and it just stops there.]]
* FanNickname:
** [[CrazyAwesome "Batshit Ryoma"]] - Ryoma - a near permanent SlasherSmile combined with his sheer HotBlooded, balls-to-the-wall {{Determinator}} personality causes many to doubt his sanity.
** "[[WesternAnimation/SouthPark Kenny]]" - Musashi - for having to die in every continuity, HeroicSacrifice or not.
** THE RAPE MACHINE - The Black Getter from ''Armageddon'', thanks to a kickass design and a ''[[TheBerserker really]]'' [[TheBerserker aggressive fighting style]].
* RelationshipVoiceActor: In the OVAs, both [[Creator/{{HideoIshikawa}} Ryoma's]] and [[Creator/{{NaoyaUchida}} Hayato's]] voice actors are [[Franchise/{{Naruto}} Itachi Uchiha and his ancestor Madara]] respectively. Interesting, in both Armageddon and Shin vs Neo, Musashi's japanese voice actor (Shinpachi Tsuji) is also Pakkun while in New, one of the Four Heavenly Kings is also [[Creator/{{TesshoGenda}} Kurama]].
** Speaking of New, Heian Arc characters [[Creator/{{RomiPark}} Raikou]] and [[Creator/{{TakehitoKoyasu}} Seimei]] are also [[Anime/{{TurnAGundam}} Loran Cehack and Gym Ghingham]] respectively. Fitting,as both Raikou and Loran are [[{{WholesomeCrossdresser}} Heroic Crossdressers]].
* VideoGame/SuperRobotWars:
** Better to list which games ''doesn't'' include Getter in it, which are ''[[VideoGame/SuperRobotWarsJudgment J]]'', ''[[VideoGame/SuperRobotWarsK K]]'', ''[[VideoGame/SuperRobotWarsL L]]'', ''[[VideoGame/SuperRobotWarsUX UX]]'', ''[[VideoGame/SuperRobotWarsBX BX]]'' and [[VideoGame/SuperRobotWarsX X]]. Special mention in that it forms one of the corners of the "Holy Trinity" of the series, the others being Gundam and Mazinger. Another special mention is that VideoGame/SuperRobotWarsX is also the first-console game which Getter is absent.
** Also, most of the time it appears, it's ''Getter Robo G''. ''Shin Getter vs Neo Getter'', appears in ''[[VideoGame/SuperRobotWarsReversal Reversal]]'' and ''[[VideoGame/SuperRobotWarsGC GC/XO]]'', ''Armageddon'' appeared in ''[[VideoGame/SuperRobotWarsDestiny Destiny]]'', and ''New Getter'' appeared in ''[[VideoGame/SuperRobotWarsNEO NEO]]''. ''Armageddon'', however, made a triumphant return in ''VideoGame/{{Super Robot Wars Z}}2'', and has since become SRW's go-to Getter entry.
** Shin Getter is also part of a group called the Three Gods by much of the fandom, the other two being [[Anime/GaoGaiGar Genesic GaoGaiGar]] and Anime/{{Mazinkaiser}}. In-game and in promotional art, those three robots are considered pretty much the biggest heroes of the SuperRobot type and are always shown front-and-center.
* TheOtherDarrin: After Creator/AkiraKamiya's retirement, Creator/HideoIshikawa took the role of Ryouma from ''Armaggedon'' on. He almost became a ReplacementScrappy in some parts of the fandom for trying to keep with the DarkerAndEdgier setting by giving his own spins to his voice work.
** The OVAS also changes Hayato's role from Creator/KeatonYamada to Creator/NaoyaUchida. And Shinpachi Tsuji replaces Toku Nishio in the role of Musashi.
* WhatCouldHaveBeen: Besides Ishikawa's death, Imagawa was the one who directed the first 3 episodes of Armageddon. Everything was shaping up for an intense mystery martial arts mecha mashup with all of Ishikawa's series joining the fray. Then he got sacked, simply for taking a little too long. He took the scripts with him, leaving Armageddon the aborted mess it was post-Ep3.
** Considering what we still got in the end was still awesome, it could've been worse. Still one has to wonder...
