!Trivia
* The primary theme of ''W'' involves the "[[ArtisticLicenseSpace Big Crunch]]": after a time, the universe contracts on itself, then is reborn in another Big Bang. In the backstory of ''W'', various cultures sent parts of their civilization, such as [[Anime/GaoGaiGar Galeon]] and the Anime/GoLion (as well as the [[spoiler:''Valstork'', Valhawk and the Database]]) forward in time from previous generations.
* The [[Anime/DetonatorOrgun Evoluders]] in ''W'' are a direct off-shoot of the [[Anime/TekkamanBlade Radam]]: while rescuing his son [[Anime/TekkamanBlade Takaya Aiba]], Takaya's father was also able to steal a [[Anime/TekkamanBlade Tekkaplant]] and send it to the ''Cygnus'' before it fell into a black hole. The crew of the ''Cygnus'' used the system to survive the harsh conditions of space and eventually became Evoluders. Takaya's father's consciousness ends up linked to Jupiter by [[Anime/GaoGaiGar THE POWER]].
** This is a reference to how both shows attempted to reimagine the old Tekkaman series and/or Orgun's designs were rejected Tekkaman ones.
* The [=GoLion=] team went to the same training academy as [[Anime/GaoGaiGar Guy Shishioh and Mikoto Utsugi]].
** Similarly, the [=GoLion=] was created by the [[Anime/GaoGaiGar Trinary Culture]], who created Galeon, and sent it as a defender for the Leo Union.
* Since Earth was not destroyed in WorldWarIII, the [=GoLion=] team returns to Earth after getting [=GoLion=] the assistance in fighting the [[Anime/GoLion Galra Empire]]. Meanwhile, [[Anime/GoLion Honerva and Saki]] decide to join forces with [[Anime/{{Mazinkaiser}} Dr. Hell]] in order to destroy them.
* [[Anime/GaoGaiGar Mike Sounders the 13th]] appears earlier in the ''[=GaoGaiGar=]'' storyline, running off on his own and meeting [[Anime/GaoGaiGar Mamoru Amami]] (as well as [[Literature/FullMetalPanic Kaname Chidori]] and the [[Characters/SuperRobotWarsW Ardygun family]]) at the Marine World Amusement Park.
* Instead of hiding out in an alternate dimension, [[Anime/GaoGaiGar the Eleven Masters of Sol place Pisa Sol]] near the planet Venus, hiding it in front of the sun.
* [[Literature/FullMetalPanic Seina]] survives the battle in Tokyo, and joins up with [[Anime/MobileSuitGundamSEED Cagalli Yula Atha's]] resistance force, along with [[Anime/MobileSuitGundamWing Quatre Raberba Winner]]. [[spoiler:She is KilledOffForReal during the [[Anime/MobileSuitGundamSEED "Battle of Orb"]]]].
* The Radam (and presumably the Evoluders) are proven to be immune to the [[UnwillingRoboticisation Zonderization process]]. [[Anime/GaoGaiGar The Machine Kings]] attempt to kidnap [[Anime/TekkamanBlade Miyuki "Tekkaman Rapier" Aiba]] during her escape to find a way around this.
* ''W'' takes great pleasure in ''not'' killing off [[spoiler:[[Anime/MartianSuccessorNadesico Gai Daigoji]]: his in-series death is averted, due to the episode where he gets KilledOffForReal and the following one where [[Anime/MartianSuccessorNadesico Ryoko Subaru]] and her squad is introduced being merged into the same scenario. While it appears he dies helping the crew of the ''Nadesico'' escape to Mars, he returns during the climatic battle over the ruins to save [[Anime/MartianSuccessorNadesico Akito Tenkawa from Hokushin]], along with [[Anime/MartianSuccessorNadesico Tsukumo Shiratori]], who missed ''his'' own death due to the fact that the changes to the ''Nadesico'' plot also changed whom [[Anime/MartianSuccessorNadesico Genichiro Tsukiyomi]] shot (ironically enough, it's ''Gai'', which he '''still manages to survive'''). Finally, Gai collapses at the end of that scenario, apparently not fully recovered from his wounds, but he live through that, too]].
* [[spoiler:[[Anime/MobileSuitGundamSEED Fllay Alster]]]] survives due to the fact the entire scenario objective dealing with [[Anime/MobileSuitGundamSEED Rau Le Crusset]] [[spoiler:transferring her and the N-Jammer Canceller plans to [[Anime/MobileSuitGundamSEED Muruta Azrael]] is to prevent it from happening at all. Thus, she is safely ''far'' away from the "[[Anime/MobileSuitGundamSEED Battle of Jachin Due]]" when it occurs]]. Unfortunately, [[spoiler:even without the Cancellers]], the Earth Alliance instead develops ''Anti-Matter'' missiles to use on the [[Anime/MobileSuitGundamSEED PLANTs]]. [[NiceJobBreakingItHero Nice job breaking it]], [[BadassArmy "Neue Wärter"]].
* In order to keep all its members close by, Wärter has [[Anime/{{Mazinkaiser}} Kouji Kabuto]] and the ''Manga/GetterRobo '' team transfer to Kaname's school. To think that [[Literature/FullMetalPanic Sousuke Sagara]] alone was bad...
** This gets worse when [[Anime/GaoGaiGar Bionet]] uses the "Poniman" incident as a cover to try and kidnap Kaname. Depending on the playthrough, this can be kicked off with a [[Anime/MartianSuccessorNadesico Daimajin]] getting destroyed by [[Anime/FullMetalPanicFumoffu Bonta-Kun]].
** Also, Akito decides to spend his downtime running a ramen shop near the school.
** Since he doesn't have to go to school, [[Characters/SuperRobotWarsW Kazuma Ardygun]] opts out figuring it'd be better to train and become a pilot. To his horror, he winds up getting TrainingFromHell from [[Literature/FullMetalPanic Melissa Mao]] and [[Anime/MobileSuitGundamWing Lucrenzia Noin]]. This doesn't do him any favors regarding him [[RunningGag meeting girls, either]].
* In ''W'', the [[Manga/GetterRobo Shin Getter Robo]] is built primarily as a check against the Anime/{{Mazinkaiser}}, just in case it goes berserk when activated. [[spoiler: Though dialogue with the Database during the final stage implies that Shin Getter is even more dangerous than what it's supposed to stop, as Inference implies that it could destroy the universe when fully awakened.]]
* The [[Anime/MartianSuccessorNadesico Jovians]] were given the ''Anime/{{Gekiganger 3}}'' discs by [[Anime/MobileSuitGundamSEED George Glenn]]. A mistake on his part, since he was planning on giving them data discs. [[spoiler:Unfortunately, this winds up being the spark that ignites conflict between the Jovians and the Earth]].
* The event in ''Anime/TekkamanBlade II'', the Black September of Prague, is omitted to fit the storyline. Because of this, Natasha's father and her estranged relations with him are basically AdaptedOut and instead of being arrested and executed to stop the event, Noal lives through the whole series. Dead's motivation is also changed, now he's angry at Blade for not being quick enough to eliminate the Radams that they managed to rob him his humanity, so he joined the Radam for vengeance against Blade.

!Tropes
* FanTranslation: The game was translated into English by a team consisting of Kingcom (known for previous ''Super Robot Wars'' fan translations, including ''W'''s [[VideoGame/SuperRobotWarsJudgment immediate predecessor]]), [=Brunom1=], and Fei, among others.
* NoExportForYou: Rather typical for the franchise, though it's a little more surprising for ''W'' since every series in the game was licensed for North American distribution at the time of release, and a couple series (''[=GoLion=]'', ''Orgun'' and ''possibly Tekkaman Blade'') seem to have been included more to appeal to an American audience than any fan demand in Japan (which is particularly non-existent for ''[=GoLion=]''); idle speculation formented the idea that this was done to increase international appeal, but the game still never crossed the Pacific officially.
** Ironically, it probably had to do with ''[=GoLion=]/Voltron'', since there are discussions about the ownership of the series for the American market.
*** A panel with Media Blasters claimed the license for Voltron was in order...until {{Creator/Nickelodeon}} optioned ''WesternAnimation/VoltronForce''. The optioning prevented games with the Voltron license from being released without Nick's approval, and the ensuing legal drama kept the game from being exported.
* ReferencedBy: One of the ''Manga/LuckyStar'' anime adaptation's numerous {{Shout Out}}s to ''Literature/FullMetalPanic'' is done in the style of this game, down to imitating both flavors of SuperMovePortraitAttack and coming very close to the game's actual animations for the Arbalest and Codarl-i.
* WhatCouldHaveBeen: An option for a female protagonist was planned at one point, and there was even a portrait of a male version of Aria in the game, who would have been the female protagonist's rival instead. The male Aria portrait was edited and reused as the mugshot of the [[CloneArmy Deceivers]].
