!!Original Generations
* All pre-made ''Alpha'' protagonists [[DivergentCharacterEvolution become original characters]]. In the ''Alpha'' series, only[[Characters/SuperRobotWarsAlpha Kusuha Mizuha and Brookyln "Bullet" Luckfield]] were given unique personalities.
* The scene where [[Characters/MasouKishin Masaki Andoh]] uses the Cybuster and displays its power at Wake Island was pastiched from ''VideoGame/SuperRobotWars2''. Likewise, the scene with the first appearance of [[Characters/MasouKishin Lune Zoldark]] is a replica of a similar event from ''VideoGame/SuperRobotWars3''.
* In RealLife, the mechanical design of the Wildschwein is based off of an early mechanical design for the Huckebein. In-story, however, the Huckebein line was developed directly from the Wildschwein.
* Unlike ''[[VideoGame/SuperRobotWarsAlpha Super Robot Wars Alpha Gaiden]]'', the [[Characters/SuperRobotWarsAlpha Machinery Children]] in ''Original Generation 2'' are clones of [[Characters/SuperRobotWarsAlpha Arado Balanga]], not [[Characters/SuperRobotWarsAlpha Egret Fehu]].
* [[CombinationAttack Rampage Ghost]] can be used with the Rein Weiss Ritter for the first time in ''Original Generation 2''. In ''[[VideoGame/SuperRobotWarsCompact2 Super Robot Wars Impact]]'', the player has a choice of either reverting the Rein to normal or keep it as it is but lose the [[GetterRobo Shin Getter Robo]]; doing the latter, however, gains Rampage Ghost for the normal Weiss Ritter and Alt Eisen Riese, something ''Original Generation'' doesn't have.
* In-universe, the Wild Falken and Wild Wurger are meant to be a GenerationXerox of the Weiss Ritter and Alt Eisen, respectively.
* The key differences between the [[Characters/SuperRobotWarsAdvance Shadow-Mirror]] dimension and the Original Generation universe are as follows:
** The "Elpis Incident" killed off the entire [[Characters/SuperRobotWarsAlpha Branstein family]]. Fortunately, the youngest son [[Characters/SuperRobotWarsAlpha Raidiese]] survived; however, he was killed during the "Vanishing Trooper Incident". This event also made it taboo among mechanical designers to ever manufacture another [[AMechByAnyOtherName Personal Trooper]] that resembles a Huckebein, which explains the proliferation of Gespensts within the Shadow-Mirror.
** The [[Characters/SuperRobotWarsOriginalGeneration Aerogaters]] did not arrive after the [[CivilWar Divine Crusaders War]]: it was the [[Characters/SuperRobotWarsClassic Inspectors]]. Similarly, Meteor-3 did not crash on the Earth; it's implied the radioactive mineral "Tronium" used to power the SRX was brought to Earth rather than being found within the meteor.
** [[spoiler:[[Characters/SuperRobotWarsCompact2 Excellen Browning]] died in the shuttle crash. Her parents took her body and resuscitated her through science and technology, rendering her into [[Characters/SuperRobotWarsAdvance Lemon Browning]]]]. Likewise, [[Characters/SuperRobotWarsAlpha Sanger Zonvolt]] was killed-in-action: [[spoiler:his body was taken by the Shadow-Mirror and rebuilt into the W-Numbers [[Characters/SuperRobotWarsOriginalGeneration W-15 "Wodan Ymir"]]]].

!!Original Generation Gaiden
* Instead of the [[MobileFighterGGundam Devil Gundam]] dispatching the [[Characters/SuperRobotWarsMX Cry Wolves]], it was a [[spoiler:[[Characters/SuperRobotWarsCompact2 Jetzt Regisseur]]]].
* For both ''Alpha Gaiden'' and this title, [[Characters/MasouKishin Shu Shirakawa]] is the TrueFinalBoss. However, he blatantly states that he serves "[[Characters/MasouKishin Shiva Volkruss]]" for this game, instead of referring to it as "a being" for ''Alpha Gaiden''.
* Backstory in ''VideoGame/SuperRobotWarsCompact3'' loosely mentions another ''Heaven''-class Shura God in the Swordian Fortress. It still remains in slumber by the end of the game.

!!The Second Original Generation
* [[Characters/SuperRobotWarsOriginalGeneration Ing Egret]] is [[spoiler:not a Machinery Child: he's a clone of [[Characters/SuperRobotWarsAlpha Ingram Plisken]]. This is why [[Characters/SuperRobotWarsAlpha Euzeth Gozzo]] absorbs him in the final scenario of the ''Second Original Generation'', in hopes to take a sample of Ingram's DNA]]. Most people have inferred that Egret Fehu was working for [[spoiler:Euzeth]] all along, just like [[spoiler:[[Characters/SuperRobotWarsOriginalGeneration Nibhal Mubhal]]]] has been doing since the very beginning.
* Back in ''Super Hero Sakusen'' ("Super Hero Operations"), Euzeth used the power of Series/{{Ultraman}} to become Chojin Zest, an {{Expy}} of [[Series/UltramanTiga Evil Tiga]]. [[spoiler:In the ''Second Original Generation'', he does the same, but with the [[Characters/SuperRobotWarsAlpha Nashim Gan Eden]] instead of Ultraman, becoming the Adamatron]].
* The [[Characters/SuperRobotWarsClassic Zuvorg Alliance]] haven't directly fought the [[Characters/SuperRobotWarsAlpha Ze Balmary Empire]]: in fact, it's unclear if the latter even exists in ''Original Generation''. It's suggested the Zuvorg had scuffles on the edges of their systems with the Balmar's Neviim and their automated legions and such, referring to those things as the "wandering Balmar".
* The fate of [[Characters/SuperRobotWarsDestiny Perfectio]] remains the same, except [[spoiler:[[Characters/SuperRobotWarsDestiny Ventus]]]] is the one who takes the place of [[MobileSuitGundamWing Treize Kushrenada]]. Perfectio even reveals the memories of [[spoiler:[[Characters/SuperRobotWarsDestiny Felio Radcliffe]]]], which fills in some lingering {{Plot Hole}}s from ''VideoGame/SuperRobotWarsDestiny'', namely explaining the SplitPersonality of [[Characters/SuperRobotWarsDestiny Cliana Rimskaya]], since the ''Second Original Generation'' did not use the experimentation trauma from ''Destiny'' which caused the split, and where the missing Melior Esse comes from ([[spoiler:Liana being an incomplete Melior Esse]]). Perfectio also notes about [[{{Precursors}} an ancient civilization that created the Cross Gate]].
* The Medius Locus stops evolving after it reaches its second form because [[spoiler:[[Characters/SuperRobotWarsMX Eldy Mitte]]]] assassinates [[Characters/SuperRobotWarsMX Albero Est]], believing he is an obstacle for the AI-1's evolution. The Medius Locus is discarded afterwards; instead, its replacement is the [[spoiler:Model-X "Garberus", previously hinted at in ''VideoGame/SuperRobotWarsMX'', and the intended final prototype of the Tsentr Project]].
* Rather than use the [[{{Raideen}} the Star of La-Mu]] in ''MX'', Eldy uses the Crossgate beneath Antarctica to power up AI-1. [[Characters/SuperRobotWarsOriginalGeneration Duvan Org]] tries to do it too, but the Alles Geist can't handle its power. Since Eldy is simply using Duvan to buy time, the AI-1 consumes him once she doesn't need him anymore.
* The [[Characters/SuperRobotWarsOriginalGeneration Gaia Sabers]] don't seem to really mind Eldy, in general (until it turns out [[spoiler:Euzeth]] was counting on her to complete the AI-1 all along), and General Mitall Zapad was openly trying to stop her from working on it. Like ''MX'', [[spoiler:Eldy eventually kills Mitall for interferring with her plans]].
* The plan to include [[Characters/SuperRobotWarsOriginalGeneration Arteil Steinbeck]] in the story has been around since they were drawing up the story for ''Original Generation''. The writers even thought about adding him to ''Divine Wars'', ''Original Generations'' and ''The Inspectors''. Instead, Steinbeck is briefly mentioned in ''Original Generation Gaiden'' before appearing fully for the ''Second Original Generation''.
* The dialogue during the [[spoiler:"Elyon Yada Domar" attack of the Adamatron]] mentions the following, with an appropriate silhouette(s):
--> "This is the Black Hell" [[note]][[spoiler:Euzeth's Black Judecca]][[/note]]
--> "This is the Black Angel" [[note]][[spoiler:Astranagant]][[/note]]
--> "This is the Black Gun God" [[note]][[spoiler:Dis Astranagant]][[/note]]
--> "These are your ancient forebearers" [[note]][[spoiler:Nashim Gan Eden and Gebel Gan Eden]][[/note]]

!The Inspectors
* In the first episode, aside from the SRX that Beowulf destroys, two other machines are seen. According to WordOfGod, they are the Grungust and the Wildraubtier.
** The Huckebeins being ExiledFromContinuity in ''Divine Wars'' is continued to the point of self-parody: Bullet's intended Huckebein MK II and its mass-produced variants are replaced by a mass-produced Wildschwein (a mech that ''also'' resembles a {{Gundam}}, though not as much as the Huckebein). Likewise, the "[=GuarBein=]" MK III Trombe belonging to [[Characters/SuperRobotWarsOriginalGeneration Ratsel Feinschmecker]] in episode nine is a mish-mash of the Huckebein MK III and his old Guarlion Custom, while [[Characters/SuperRobotWarsAlpha Ryoto Hikawa]] gets the '''[=EX=]'''bein, the in-universe prototype of the MK III.
* The {{Leitmotif}} "Fairy Dang-Sing" heard in episode ten is the first time since ''Alpha'' that a character's theme song is given official lyrics. Current [=SRW=] series producer Takenobu Terada wrote the lyrics, with the voice actresses for [[Characters/SuperRobotWarsOriginalGeneration Latooni Subbota and Shine Hausen]] singing it.
** In the same episode, the SuperRobot ''Gravilion'' used by [[Characters/SuperRobotWarsOriginalGeneration Archibald Grims]] is a case of WhatCouldHaveBeen: the animated staff states the Gravilion was originally going to be in the first game as an enemy unit for the Divine Crusaders, but this was dropped during development. Eventually, they decided to bring it into ''The Inspectors'' to showcase the Neo Divine Crusaders having access to exotic, {{Super Robot}}s other than the Valsion Custom in ''Divine Wars''.
* In episode nineteen, the voices of the [=RyuOhKi=] and [=KoOhKi=] are Masami Obari and Terada, respectively. This marks the first time the Choukijin are voiced.

!Tropes
* ActorAllusion: Of sorts; the voice actor for Russel Bagman has no other roles, because his primary job is "director photographer". In other words, he's the one in charge of the background.
* AscendedFanon: Latooni and use of the Wildraubtier. ''Original Generation'' wasn't very demanding in terms of "mandating" players to put which character in which unit, and due to her lack of plot focus, the game allows Latooni to be in any mecha without protest. However, savvy players will put two-and-two together and place her in the Wildraubtier the instant [[Characters/SuperRobotWarsAlpha Ryusei Date]] is done with it, due to it matching her high evasion stat and ranged combat style perfectly. This didn't go unnoticed by the developers, and in ''Original Generations'', the switch became mandatory. Even when she isn't using the Fairlion, the Wildraubtier remains her default unit.
* ColbertBump: A meta-example - [[Characters/SuperRobotWarsClassic Lenonjayce Stallord and Patricia Hackman]] may have created some of the Gespenst's more famous attacks, but by the time ''Original Generation'' came around, the machine had fallen on hard times. When Kai Kitamura shows up, he gives the Gespenst a well-deserved bump back into the halls of awesome. InUniverse, he takes this further by designing the MK II M Custom in ''Original Generation Gaiden'' on his own (with some internal support from [[Characters/SuperRobotWarsClassic Gilliam Yeager]]) and promoting its benefits to the higher-ups.
* FanNickname
** "Dytrombe"/"Daitrombe" for the Aussenseiter, particuarly when it transforms into a MechanicalHorse via "Pferd Mode"; bonus points as Ratsel's stallion is named "Trombe".
** "Goth Lolion" for the Fairlion due to its ElegantGothicLolita design
** "Yoga-tan" for Radha Byraban, for obvious reasons
** Thanks to its appearance in ''The Inspectors'', "[[DoesThisRemindYouOfAnything Rapecage]]" for "Rapiecage"
** "[[MobileSuitZetaGundam Not-Titans]]" for the Gaia Sabers
** "Ultraman [[spoiler:Zest ]]" for [[spoiler:Euzeth Gozzo]]
* HeyItsThatVoice: Since the main cast is craploaded with them, this is for those exclusively in ''Original Generation''.
** Ratsel is [[Anime/TurnAGundam Harry Ord]] and [[DynastyWarriors Lu Bu]]
** Kai is [[FateStayNight Berserker]], when he actually speaks coherently.
** Kouta Azuma can't use the "[[Anime/GenesisOfAquarion Mugen Punch]]" or shout "[[{{Franchise/Jewelpet}} Burning]]", but he sure does sound like the person who uses it.
** Daitetsu Minase is the male half of [[MazingerZ classic Baron Ashura]]: ''no joke''...oh, and [[spoiler:like a certain [[{{Naruto}} old ninja, who doubles as the village's leader]], he too gets killed by a {{Face Heel Turn}}ing subordinate]].
** Lefina Enfield is [[Manga/CardcaptorSakura Tomoyo]], [[Anime/NeonGenesisEvangelion Hikari]] and [[MaiHime Akane]]
** Radha Byraban is [[Anime/OnegaiMyMelody My Melody]]
** Ariel Org is [[Franchise/{{Jewelpet}} Gumimin]]
** Rishu Tougou is [[DynastyWarriors Zuo Ci]]
** Imagine Kenneth Garret as [[{{Franchise/Jewelpet}} Aoi's new butler]]
** Brian Midcrid is [[{{Manga/Bleach}} Sosuke Aizen]] and [[SuperDimensionFortressMacross Maximillian Jenius]]
** Tenzan Nakajima is [[Anime/TurnAGundam Corin Nander]]
** Maier von Branstein is [[CodeGeass Charles zi Britannia]] and [[{{Hellsing}} Alexander Anderson]]
** Van Vat Tran is Albero
** Archibald Grims is an evil, crazed version of [[MacrossPlus Isamu Alva Dyson]], minus the variable fighter.
** Ouka Nagisa is [[Anime/FullmetalAlchemist Riza Hawkeye]] and [[LightNovel/FullMetalPanic Melissa Mao]]
** Wilheim von Juergen is [[VideoGame/TalesOfSymphonia Kvar]]; too bad there's no [[VideoGame/TalesOfSymphonia Kratos Aurion]]-equivalent in ''Original Generation'' telling him to "Feel the pain! Of those inferior beings! As you burn in Hell!"
** Mitsuko Isurugi is [[Characters/SuperRobotWarsZ Setsuko Ohara]]
* IKnewIt: Played with - fans deduced Beowulf is associated with the [[Characters/SuperRobotWarsCompact2 Einsts]] via FacialMarkings under his eyes in his character portrait for ''Original Generations'', similar to [[Characters/SuperRobotWarsCompact2 Einst Alfimi]]. The ''Endless Frontier'' drama CD doesn't tell us why the MK III could regenerate a lost limb, after [[Characters/SuperRobotWarsAdvance Axel Almer]] uses the Soulgain to destroy it, further fueling the speculation he is tied to the {{Eldritch Abomination}}s. The first five minutes of ''The Inspectors'' confirms this, but its validity in the games' {{Continuity}} has not been established yet.
* TalkingToHimself
** ReiSakuma also voices [[Characters/MasouKishin Kuro]], one of Masaki's two {{Familiar}} cats.
** Creator/YumikoKobayashi voices Ariel, the same voice actress as Ryoto, except this time it isn't a CrossdressingVoice.
** Subverted with Keparoc Narmo; despite Creator/TetsuInada voicing him, he and Ratsel do not meet.
** KenyuuHoriuchi voices Jonathan Kazahara and his son [[Characters/SuperRobotWarsClassic Irmgard Kazahara]] in ''The Inspectors''.
* TheOtherDarrin
** Creator/ShihoKawaragi as Eun Hyojin
** YuuAsakawa as Aguija in ''The Inspectors''
** Kousuke Okano as Lee Linjun in ''The Inspectors''
