!!Original Generations
* All pre-made ''Alpha'' protagonists [[DivergentCharacterEvolution become original characters]]. In the ''Alpha'' series, only [[Characters/SuperRobotWarsAlpha Kusuha Mizuha and Brookyln "Bullet" Luckfield]] are given unique personalities.
* The scene where [[Characters/MasouKishin Masaki Andoh]] uses the Cybuster and displays its power at Wake Island is 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. This is referenced InUniverse, as the Huckebein line is developed directly from the Wildschwein.
* Unlike ''[[VideoGame/SuperRobotWarsAlpha Super Robot Wars Alpha Gaiden]]'', the [[Characters/SuperRobotWarsAlphaGaiden Machinery Children]] in ''Original Generation 2'' are clones of [[Characters/SuperRobotWarsAlpha2 Arado Balanga]], not [[Characters/SuperRobotWarsAlphaGaiden Egret Feff]].
* "[[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]]'', players have an choice of either reverting the Rein to normal or keep it as it is but lose the [[Manga/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.
* InUniverse, 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" kills off the entire [[Characters/SuperRobotWarsAlpha Branstein family]]. Fortunately, the youngest son [[Characters/SuperRobotWarsAlpha Raidiese]] survives; however, he dies during the "Vanishing Trooper Incident". This event also makes it taboo among mechanical designers to ever manufacture another "[[AMechByAnyOtherName Personal Trooper]]" resembling a Huckebein, which explains the proliferation of Gespensts within the Shadow-Mirror.
** The "[[Characters/SuperRobotWarsOriginalGenerationAntagonists Aerogaters]]" do not arrive after the "[[CivilWar Divine Crusaders War]]": it's the "[[Characters/SuperRobotWarsClassic Inspectors]]". Similarly, Meteor-3 does not crash on the Earth; it's implied the radioactive mineral "Tronium" used to power the SRX is brought to Earth rather than being found within the meteor.
** [[spoiler:[[Characters/SuperRobotWarsCompact2 Excellen Browning]] dies in the shuttle crash. Her parents take her body and resuscitate her through science and technology, rendering her into [[Characters/SuperRobotWarsAdvance Lemon Browning]]]]. Likewise, Sanger is killed-in-action: [[spoiler:his body is taken by the Shadow-Mirror and rebuilt into the W-Numbers [[Characters/SuperRobotWarsOriginalGenerationAntagonists W-15 "Wodan Ymir"]]. It's implied the "[[Characters/SuperRobotWarsCompact2 Einst]]", instead of Excellen, targets [[Characters/SuperRobotWarsCompact2 Kyosuke Nanbu]], creating the destructive "[[Characters/SuperRobotWarsOriginalGenerationAntagonists Beowulf]]"]].

!!Original Generation Gaiden
* One of the ploys of [[Characters/SuperRobotWarsReversal Duminuss]] is to use a dead character close to the protagonists in order to demoralize them. In its [[VideoGame/SuperRobotWarsReversal original game]], [[Anime/MobileFighterGGundam Master Asia]] is brought BackFromTheDead via "[[Anime/MobileFighterGGundam Devil Gundam Cells]]" until an overload of "[[Manga/GetterRobo Getter Rays]]" purged it from his body. In ''Original Generation'', [[spoiler:[[Characters/SuperRobotWarsAdvance Lamia Loveless]] is used; rather than "[[Characters/SuperRobotWarsAlphaGaiden Machine Cells]]" (the ''Original Generation'' [[{{Expy}} equivalent]] of Devil Gundam Cells), she's reprogrammed in a way where it might not be possible to restore her (since she's the last of the Shadow-Mirror). [[Characters/SuperRobotWarsAdvance Axel Almer]], who's NotQuiteDead, reboots Lamia into her original programming via "Code: DTD"]].
* Instead of the [[Anime/MobileFighterGGundam Devil Gundam]] dispatching the "[[Characters/SuperRobotWarsMX Cry Wolves]]", it is a [[spoiler:[[Characters/SuperRobotWarsCompact2 Jetzt Regisseur]]. Subsequently, [[Characters/SuperRobotWarsMX Foglia Est]] isn't zombified a la the back-story of ''VieoGame/SuperRobotWarsMX'' and had to be given a MercyKill; instead, he pulls a HeroicSacrifice for his father [[Characters/SuperRobotWarsMX Albero Est]]]].
* For ''Alpha Gaiden'' and this installment, [[Characters/MasouKishin Shu Shirakawa]] is the TrueFinalBoss. However, he blatantly states he serves "[[Characters/MasouKishin Shiva Volkruss]]" for this game instead of referring to it as "a being" for ''Alpha Gaiden''. Meanwhile, the final battle against him in ''Original Generation Gaiden'' is more of a parallel to the same one from ''Super Robot Wars 3'' than ''Alpha Gaiden'' by summoning several automated Valsion units, with the title of the scenario being called "Armageddon", the same one from ''3''.
* Back-story 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
* Back in ''VideoGame/SuperRobotWarsEX'', playing Masaki's route will lead to him and his allies encountering the Elemental Lord Zamzeed under control of the Shutendonias Alliance, with vague mentions that [[Characters/MasouKishin Tytti Noorbuck]] has a history with the machine. It isn't until ''The Lord of Elemental'' is released this PlotHole is resolved; as LateArrivalSpoiler is in play for this game regarding ''Masou Kishin'', Tytti explicitly tells the surface dwellers the Zamzeed was previously used by their [[PosthumousCharacter posthumous comrade]] [[Characters/MasouKishin Ricardo Silvera]]. The game also highlights Tytti's conflicting emotions when [[Characters/MasouKishin Mio Sasuga]] is chosen to be Ricardo's successor.
* [[Characters/SuperRobotWarsOriginalGenerationSteelDragonBattleGroup Ing Egret]] is [[spoiler:not a Machinery Child: he's a clone of [[Characters/SuperRobotWarsAlpha Ingram Plisken]]. [[Characters/SuperRobotWarsAlpha Euzeth Gozzo]] uses Ing as an "artificial pilot" in place of [[Characters/SuperRobotWarsAlpha2 Irui Gan Eden]] to control the [[Characters/SuperRobotWarsAlpha2 Nashim Gan Eden]]]] in the final scenario of the ''Second Original Generation''. Most people have inferred that Egret Feff was working for [[spoiler:Euzeth]] all along, just like [[spoiler:[[Characters/SuperRobotWarsOriginalGenerationEarthFederation 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 create the "Chojin Zest", an {{Expy}} of [[Series/UltramanTiga Evil Tiga]]. [[spoiler:In the ''Second Original Generation'', he does the same, but with the Nashim Gan Eden instead of Ultraman, creating the "Adamatron"]].
* It's explicitly stated the "[[Characters/SuperRobotWarsClassic Zuvorg Alliance]]" haven't directly fought the "[[Characters/SuperRobotWarsAlpha Ze Balmary Empire]]". It's suggested the Zuvorg had scuffles on the edges of their systems with the Balmar's "Neviim" lunar satellites 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 [[Anime/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'' regarding the SplitPersonality of [[Characters/SuperRobotWarsDestiny Cliana Rimskaya]], since the ''Second Original Generation'' does 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 [[Characters/SuperRobotWarsMX Medius Locus]] stops evolving after it reaches its second form because [[spoiler:it absorbs Albero into its Lasmunanium]]; the machine is discarded afterwards. Instead, its replacement is the [[spoiler:Model-X "Garberus"]], previously hinted at in ''MX'' and the intended final prototype of the "[[Characters/SuperRobotWarsMX Tsentr Project]]".
* Rather than use the "[[{{Anime/Raideen}} the Star of La-Mu]]" in ''MX'', [[spoiler:[[Characters/SuperRobotWarsMX Eldy Mitte]] uses the Cross Gate in the Fabula Fores beneath Antarctica to power up the "[[Characters/SuperRobotWarsMX AI-1]]". [[Characters/SuperRobotWarsOriginalGenerationAntagonists Duvan Org]] also attempts it, but the Alles Geist can't handle its power. Since Eldy is simply using Duvan to buy time, the AI-1 absorbs Duvan and the Alles, turning into its final form from ''MX'']].
* In general, the "[[Characters/SuperRobotWarsOriginalGenerationAntagonists Gaia Sabers]]" don't seem to really mind what [[spoiler:Eldy]] is doing throughout the game (until it turns out [[spoiler:Euzeth was counting on her to complete the AI-1 all along]]), and General Mitall Zapad was openly trying [[spoiler:to stop her from working on it. Like ''MX'', Eldy eventually kills Mitall for interferring with her plans]].
* The plan to include [[Characters/SuperRobotWarsOriginalGenerationAntagonists Arteil Steinbeck]] in the story has been around since the developers 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 [[Characters/SuperRobotWarsAlpha3 Gebel Gan Eden]]]][[/note]]

!The Moon Dwellers
* In ''VideoGame/SuperRobotWarsJudgment'', the "[[Characters/SuperRobotWarsJudgment Fury]]" state they were locked in a previous war with another faction to determine the fate of the Earth. In ''The Moon Dwellers'', this mysterious faction are [[spoiler:[[Characters/SuperRobotWarsDestiny Perfectio and the Ruina]], whom the Fury sealed with the "Fabula Fores" in the Antarctic. The "Granteed" constructed by the Fury serves as a countermeasure in the event Perfectio returns]].
** Building off the above, [[spoiler:the "Sympathia System" used in the ''Destiny'' HumongousMecha are replicas of the Fury's "Cytron Control System", first hinted at when [[Characters/SuperRobotWarsDestiny Joshua Radcliffe]] is using his "Geant Chevalier" and it resonates with the Granteed; this is later confirmed]].
* Following TheReveal in ''Judgment'' regarding [[spoiler:[[Characters/SuperRobotWarsJudgment Al-Van Lunks]]]], [[Characters/SuperRobotWarsJudgment Calvina Coulange]] starts taking out her anger on her co-pilot trio, leading to [[LightNovel/FullMetalPanic Melissa Mao]] [[GetAHoldOfYourselfMan slapping some sense into Calvina]]. In ''The Moon Dwellers'', she demands to know from [[Characters/SuperRobotWarsJudgment Touya Shiun]] [[spoiler:if his father knew of Al-Van being TheMole for the Fury]], leading to Touya accusing Calvina of possibly conspiring with the enemy. [[Characters/SuperRobotWarsClassic Irmgard Kazahara]] steps in to intervene; while there's no ArmorPiercingSlap, [[Characters/SuperRobotWarsAlpha Aya Kobayashi]] mentions to Calvina [[YouAreNotAlone she isn't the first person to have been betrayed]] [[CallBack by one whom they thought was their ally]], a clear reference to [[spoiler:Ingram's FaceHeelTurn]].

!The Inspectors
* In the first episode, aside from the SRX 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 Franchise/{{Gundam}}, though not as much as the Huckebein). Likewise, the "[=GuarBein=]" MK III Trombe belonging to [[Characters/SuperRobotWarsOriginalGenerationSteelDragonBattleGroup 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 InUniverse prototype of the MK III.
* The {{Leitmotif}} "Fairy Dang-Sing" heard in episode ten is the first time since ''Alpha'' a character's theme song is given official lyrics. Current [=SRW=] series producer Takanobu Terada wrote the lyrics, with the voice actresses for [[Characters/SuperRobotWarsOriginalGenerationSteelDragonBattleGroup Latooni Subbota and Shine Hausen]] singing it.
** In the same episode, the SuperRobot ''Gravilion'' used by [[Characters/SuperRobotWarsOriginalGenerationAntagonists 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 Creator/MasamiObari and Terada, respectively. This marks the first time the Choukijin are voiced.

!Tropes
* ActorAllusion: Of sorts; the voice actor for [[Characters/SuperRobotWarsOriginalGenerationSteelDragonBattleGroup 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'' isn't demanding in terms of "mandating" players to put which character in whichever unit; 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 becomes mandatory. Even when she isn't using the Fairlion, the Wildraubtier remains her default unit. Made more obvious when the Wildraubtier "Schnabel" is personally fine-tuned InUniverse by Latooni herself before the events of the ''Second Original Generation''.
* CastingGag: When [[Characters/SuperRobotWarsOriginalGenerationSteelDragonBattleGroup Shouko Azuma]] turns into "[[HenshinHero Fighter Emi]]", her helmet is shaped like a cat's head, a reference to Shouko's voice actress Creator/HiromiKonno and her role as Neko Musume from the 2007 version of ''Manga/GeGeGeNoKitaro''.
* ColbertBump
** Meta-example - [[Characters/SuperRobotWarsClassic Lenonjayce Stallord and Patricia Hackman]] may have created some of the Gespenst's more famous attacks, but before ''Original Generation'' was released, the machine was largely forgotten by [=SRW=] players. When [[Characters/SuperRobotWarsOriginalGenerationSteelDragonBattleGroup Kai Kitamura]] makes his debut in the games, who demonstrates why the Gespenst isn't a simple {{Mook}} unit, fan reception to the mech, largely due to Kai's {{Memetic Badass}}ery with the machine, gave it a well-deserved bump back up on par with other units like the SRX and Dygenguard. By the ''Second Original Generation'', the Gespenst is as easily recognizable as some of players' favorite units throughout the franchise.
** {{Irony}} ensues InUniverse: TheFederation originally intended to scrap the Gespenst in favor of the cost-efficient, mass-produced Huckebein until Kai takes this further by designing a customized, mass-produced Gespenst MK II in ''Original Generation Gaiden'' on his own (with some internal support from [[Characters/CompatiHeroSeries Gilliam Yeager]]) and promoting its benefits to the higher-ups. By the ''Second Original Generation'', these Gespenst MK II Custom units are used widely by the military over the Huckebein.
* ContestWinnerCameo: [[Characters/SuperRobotWarsOriginalGenerationSteelDragonBattleGroup Katina Tarask]] was the winner of a character design contest for a TradingCardGame.
* FanNickname: See [[FanNickname/SuperRobotWars here]] for the entries
* IKnewIt
** Played with regarding Beowulf: fans deduced he was 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 explain why Beowulf's Gespenst MK III could regenerate a lost limb after Axel 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.
** When the [[spoiler:Nashim Gan Eden]] fires a WaveMotionGun towards the moon just as the FinalBoss scenario is underway in the ''Second Original Generation'', many players believed this event was simply {{Foreshadowing}} ''Judgment'' getting into ''Original Generation'' as the villainous Fury reside deep within the moon; even [[Characters/SuperRobotWarsAlpha3 Elma]] makes a quip about this in ''Dark Prison'', citing the blast "did not hit any man-made structures". Sure enough, they serve as the headlining antagonists in ''The Moon Dwellers''.
* NamesTheSame: [[Characters/SuperRobotWarsOriginalGenerationOthersAndWalkingSpoilers Professor Kisaburo Azuma]] to [[Characters/CompatiHeroSeries Doctor Kisaburo]]
* RelationshipVoiceActor: Due to probably sharing the same hiring studio, starting with the ''Second Original Generation'', a lot of voice actors are recycled from works in the [[Creator/{{Koei}} Tecmo Koei]] ''[[VideoGame/DynastyWarriors Warriors]]'' [[VideoGame/SamuraiWarriors fran]][[VideoGame/WarriorsOrochi chise]]. For instance, with the exception of Joshua, [[Characters/SuperRobotWarsDestiny Contagio]] and Perfectio, the cast of ''Destiny'' have done at least one ''Warriors'' installment; as of ''The Moon Dwellers'', all of the ''Judgment'' cast (except the [[Characters/SuperRobotWarsJudgment co-pilot trio and Fu-Lu Mu-Lu]]).
* TalkingToHimself
** Creator/ReiSakuma voices [[Characters/SuperRobotWarsOriginalGenerationSteelDragonBattleGroup Radha Bairaban]] and [[Characters/MasouKishin Kuro]], the latter of Masaki's two {{Familiar}} cats.
** Creator/YumikoKobayashi voices [[Characters/SuperRobotWarsOriginalGenerationSteelDragonBattleGroup Ariel Org]], the same voice actress as Ryoto, except this time it isn't a CrossdressingVoice.
** Subverted with [[Characters/SuperRobotWarsOriginalGenerationAntagonists Keparoc Narmo]]; despite Creator/TetsuInada voicing him, he and Ratsel do not meet.
** Creator/KenyuHoriuchi voices [[Characters/SuperRobotWarsOriginalGenerationOthersAndWalkingSpoilers Jonathan Kazahara]] and his son Irmgard in ''The Inspectors''.
** Creator/KaoriShimizu for Lamia and [[Characters/EndlessFrontier Aschen Blodel]] in ''The Moon Dwellers''.
* TheOtherDarrin
** Creator/ShihoKawaragi as [[Characters/SuperRobotWarsOriginalGenerationSteelDragonBattleGroup Eun Hyojin]]
** YuuAsakawa as [[Characters/SuperRobotWarsClassic Aguija]] in ''The Inspectors''
** Kousuke Okano as [[Characters/SuperRobotWarsOriginalGenerationAntagonists Lee Linjun]] in ''The Inspectors''
