[[folder:Super Robot Wars Z]]
* The Sphere of the "Wounded Lion" manifests in the [[spoiler:Gunleon]], rather than a person or a combat-based HumongousMecha to avoid fighting. It would have worked too, [[spoiler:if Mel Beater hadn't been killed by [[{{Xabungle}} Breakers]]]].
* [[Anime/AfterWarGundamX Tifa Adil]] and [[EurekaSeven Eureka]] quickly become best friends, and Tifa ocasionally gives her ominous warnings about her visions of Eureka from the future. [[Anime/AfterWarGundamX Garrod Ran]] and [[EurekaSeven Renton Thurston]] form a BashBrothers-style friendship as well, and Garrod even gives Renton tips on how to handle a MysteriousWaif girlfriend. Although this gets more screentime in Rand Travis' route, it's present in both routes.
* The other prominent cross-series friendship that gets more screentime on Setsuko Ohara's route is [[Anime/MobileSuitZetaGundam Kamille Bidan]] and [[Anime/MobileSuitGundamSEEDDestiny Shinn Asuka]]. Like Garrod and Renton, they also become BashBrothers, but ''Z'' actually points out the differences between them (since the fandom likes to belive Shinn is a Kamille {{Expy}}; both are quite different, as specifically pointed out by [[Anime/MobileSuitGundam Amuro Ray and Char Aznable]]). Kamille plays TheHeart, TheSmartGuy and is considerate of others' emotions and is saddened and angered by the warfare (his CharacterDevelopment in ''Anime/MobileSuitZetaGundam'' and ''Z'' take him in a positive direction), whereas Shinn's the BloodKnight and TheBerserker who views everything as his enemy (Amuro admits to Char that sensing Shinn's malice when he blocked him from going on a murderous rampage scared him). Shinn's CharacterDevelopment in ''Anime/MobileSuitGundamSEEDDestiny'' was taken in a negative direction, and he only got worse as the show went on. While ''Z'' still has Shinn go down the drain for a while, ''Z'' doesn't take him to the same extreme the anime did, and it begins rebuilding him as a heroic figure, which truly shows in the ZEUTH route split, where he never abandons the party and goes up against [[Anime/MobileSuitGundamSEEDDestiny Gilbert Durandal]].

* The ADW has two Japans: one Japan is still free, while the other is [[Anime/CodeGeass Area 11]]. Similarly, the ADW has two moons: one is the real deal, while the other holds the [[Anime/TengenToppaGurrenLagann Cathedral Terra]]
* [[http://www.youtube.com/watch?v=0eiMViXkAQE One scenario]] involves a gladiatorial fight between [[CodeGeass Kallen Kozuki in her red RPI-11 Glasgow]] and [[ArmoredTrooperVotoms Chirico Cuvie in his comparatively inferior ATM-09-ST Scopedog]]. [[CurbStompBattle It ends against Kallen's favor]].
* The cross-series friendship continues in ''Hakai-hen'', one of which is [[Anime/MobileSuitGundamWing Heero Yuy]] and [[Anime/MobileSuitGundam00 Setsuna F. Seiei]], with the most prominent scene being the one after Heero self-detonates the [[MobileSuitGundamWing Wing Gundam]]. As he's recovering, most of the ''MobileSuitGundam Wing'', ''MobileSuitGundam00'' and ''Code Geass'' cast are there to see how he's doing, with Setsuna proclaiming "You are also Gundam".
* The ACW counterpart of Renton addresses [[OvermanKingGainer Gainer Sanga]] as "Gainer-san" and [[OvermanKingGainer Sara Kodama]] laughs at him for it. This refers back to the Renton from the UCW calling him "Gainer nii-san", which is akin to "Big Brother Gainer".
* [[Anime/MobileSuitGundam00 Lockon Stratos]] tells Setsuna that if there's someone who knows how to be Gundam, it's Amuro. In one of the final scenarios where they meet Amuro, Setsuna asks him a few questions about that.
* [[GodMars Emperor Zul]] knows quite a lot about ZEXIS, due to the amount of battles quotes he has when fighting against most of the non-voiced protagonists. He even mentions a few specific things other villains don't normally know. HOW he knows all this is another question entirely.
* [[TengenToppaGurrenLagann Lord Genome]] and Emperor Zul state they both are aware of the power of [[CodeGeass Geass when they fight Zero]], even mentioning it's the "Power of Kings". Lord Genome [[http://www.youtube.com/watch?v=O1lzW2zP71E also mentions]] that [[ShinMazinger Mazinger]] looks like Zeus and talks about the Shin Getter.
* When Chirico shoots down one of the planes from the [[GodMars Gishin Empire]], he and [[Anime/MobileSuitGundamWing Trowa Barton]] comment on their choice of weapons. The Scopedog and [[MobileSuitGundamWing Heavyarms]] possess nearly the same type of weaponry.
* In a save-quit intermission conversation between [[MacrossFrontier Ozma Lee]], [[Anime/MobileSuitGundam00 Johann Trinity]] and [[TengenToppaGurrenLagann Kamina]], they comment on how they're always stuck with a little brother/sister. All three characters are voiced by the [[Creator/KatsuyukiKonishi same voice person]].
* When the [[GetterRobo Getter Team]] meets the ''Macross Frontier'' cast, [[MacrossFrontier Alto Saotome]] states his surname, and [[GetterRobo Ryouma Nagare]] wonders if he's related to [[GetterRobo Professor Saotome]].
* [[http://www.youtube.com/watch?v=duf_39yHrnE Rather than pilot the combined Ganmen via the first movie]] (only [[TengenToppaGurrenLagann Viral]] commands it), the [[TengenToppaGurrenLagann Four Supreme Generals]] pilot their respective {{Ace Custom}}s.
[[/folder]]

[[folder:Second Super Robot Wars Z: Saisei-hen]]
* ''Gurren Lagann'' uses an original story to its plot involvement in ''Saisei-hen'' (Banpresto didn't use the TV or the movie endings: the original director made a new, unresolved conclusion exclusively for this game). In Scenario 54, [[TengenToppaGurrenLagann Simon]] uses the titular HumongousMecha to rescue [[TengenToppaGurrenLagann Nia]] from the [[TengenToppaGurrenLagann Anti-Spiral]], who uses a unit called the "[[EvilKnockOff Anti-Gurren Lagann]]". The [[MidSeasonUpgrade Arc Gurren Lagann]] only appears as a [[http://www.youtube.com/watch?v=EOjCf2NR4dY final attack]] for the Gurren Lagann, while the Chouginga Gurren Lagann does not appear at all.
* The translated version of the speech Uther Insalaum recites during the Arclinus Insarius' [[http://www.youtube.com/watch?v=HPtN0wMGeJY his strongest attack]] is as follows:
--> As the sun shines upon all creation,[[note]]Sol Lucte Omnibus[[/note]]
--> [[WellIntentionedExtremist a king's love]] is for his subjects.[[note]]Et Carita Rex Vivito Populus[[/note]]
--> [[BloodKnight You who walk]] [[FallenHero a foolish path]].[[note]]Nos Struc Qui An Prato Via[[/note]]
--> [[LightIsNotGood By the light of Salvation]], [[MercyKill Thou shalt be saved]].[[note]]Luces Se Viate Du Ad Baros[[/note]]
* The one who handles the make-up for [[Anime/MobileSuitGundam00 Tieria Erde]] when he cross-dresses to infiltrate the [[MobileSuitGundam00 A-LAWS]] is [[MacrossFrontier Bobby Margot]].
* [[ArmoredTrooperVOTOMS Wiseman]] is one of people to [[http://www.youtube.com/watch?v=lH7-_gwwDew snap]] [[CodeGeass C.C.]] out of her amnesic state.
* Kamille acts as a mentor for Setsuna during those [[http://www.youtube.com/watch?v=UDFetkztTIA trippy scenes]] when the eponymous machine of ''Gumdam 00'' allows the latter to sense the feelings of all combatants in the battlefield.
* Heero is the only non-''Code Geass'' protagonist to know Zero's identity is [[CodeGeass Lelouch Lamperouge]] before the big reveal. When [[CodeGeass Jeremiah Gottwald]] returns in Scenario 38, Heero and the [[MobileSuitGundamWing Wing Gundam Zero]] is the only unit with the ''Code Geass'' cast while everyone else, including the rest of the ''Gundam Wing'' characters, head to the Dark Continent.
** [[MobileSuitGundam00 Saji Crossroad]] is the second person that comes closest to learning of Zero's identity thanks to his job delivery pizza to [[CodeGeass Ashford Academy]] and C.C., but never actively gets any concrete evidence. Also, he's aware something is up with [[CodeGeass Rolo Lamperouge]], because having left the academy following the end of ''Hakai-hen'', his memories weren't rewritten, thus he recalls [[CodeGeass Nunnally Lamperouge]] is Lelouch's sister, but he decides to keep this to himself out of nervousness, and also since he has no idea what it means.
* [[Anime/MobileSuitGundam00 Celestial Being]] is the one who repairs (and [[http://www.youtube.com/watch?v=ZbvmfDsxP9Q upgrades]]) the [[Anime/MobileSuitGundamWing Sandrock to the Sandrock Custom]] after [[Anime/MobileSuitGundamWing Quattre Rabarba Winner]] goes on an emotional rampage with the [[http://www.youtube.com/watch?v=dOaH0tsG3z00 Wing Zero]].
* [[GenesisOfAquarion Pierre]] is a big [[MacrossSeven Basara Nekki and Fire Bomber]] fan. This is because Ozma lent Pierre his Fire Bomber CD collection.
* The Kedora event from ''Shin Mazinger'' traps every ZEXIS member in their dreams, not just [[ShinMazinger Baron Ashura and Kouji Kabuto]]. This is why various events from each respective series occur.
* Like the [[MacrossSeven Protodevlin]], Dimensional Beasts are affected by [[http://www.youtube.com/watch?v=awAi36JjFiQ Basara's singing]], damaging them in the process. Likewise, the [[MacrossFrontier Vajra]] are demoralized by Basara's songs; this explains why [[MacrossFrontier Grace O'Connor]] loses control over [[MacrossFrontier Ranka Lee]] in the ''Macross Frontier'' finale. In regards to Gaioh, whatever Basara's songs are doing is heavily affecting his abilities to control dimensional energies.
* [[Anime/MobileSuitGundam00 Ribbons Almark]] has [[http://www.youtube.com/watch?v=Vb4BP3VNlsA character-specific dialogue]] for Kamille, [[Anime/MobileSuitZetaGundam Quattro Bagina]] ("Or should I say 'Char Aznable'?"), Amuro ([[TalkingToHimself several unique battle quotes directly referencing him]]), Heero (though he's just talking about the "Zero System"), the colony Gundams as a whole, the [[Anime/AfterWarGundamX Gundam DX]] and Anime/TurnAGundam (he refers to them as the "world-destroying Gundams"), the [[Anime/MobileSuitGundamSEEDDestiny Destiny, Strike Freedom and Infinite Justice]] (he brings back the "Freedom, Justice, Destiny" motive The Edel and The Edel Bernal had back in ''Z''), Shinn and [[MobileSuitGundamSEEDDestiny Kira Yamato]]. Note that Ribbons refers to Amuro, Kamille, Shinn and Kira by their full names.
* Kallen gets a lot of interaction with the ''Gundam 00'' cast. Not only does she visit Saji in his cell on the ''[[MobileSuitGundam00 Ptolemios]], she gradually gets it into his thick skull about the situation of the ADW. Notably, when he repeatedly calls her out as a terrorist, Kallen doesn't accepts the accusation. Later, she's also responsible for motivating [[MobileSuitGundam00 Sumeragi Li Noriega]] to return, rather than Setsuna, as he promptly leaves her with Kallen, who he thinks can talk to her better because "they're both women". While Kallen believes this is the dumbest thing she's ever heard, she manages to convince her when she tells Sumeragi the story of her mother.
* The telepathic conversation Alto, Ranka and [[MacrossFrontier Sheryl Nome]] have during the ''Macross Frontier'' finale is facilitated by Setsuna [[Anime/MobileSuitGundam00 using the TRANS-AM Burst in the 00 Raiser]].
* In one of the route splits mid-game, ZEXIS is watching Ranka's concert. Setsuna and Heero are talking about the power of Ranka's song, but [[Anime/MobileSuitGundamSEEDDestiny Lacus Clyne]] corrects them and explains her song is not about power but rather a feeling. Unfortunately, both are slightly confused:
-->'''Setsuna:''' "Do you know what she's saying?"\\
'''Heero:''' "Not in the slightest."
* Crowe and Marylin Catto's relationship is pretty much a HilariousInHindsight if you take into account their voice actors portrayed [[LoveHina Keitaro Urashima and Mutsumi Otohime]], respectively.
* Sumeragi wrote a thesis back in university about combat with unmanned units. This ends up as the concept behind the [[Anime/MobileSuitGundamWing Mobile Dolls]], [[HeelRealization which is what led Sumeragi to quit]] [[Anime/MobileSuitGundamWing the Organization of Zodiac]]. They decide to put them in stuff found from the UCW.
* ''Saisei-hen'' ties [[Anime/CodeGeass Charles zi Britannia]] and C.C. to the plot by making the Code be a mark of the Black Knowledge. After Charles dies in the Sword of Akasha, Lelouch and C.C. discover the ultimate end of the universe, with the former at least trying to think of a way to avert it.
** Also, the power of Geass is revealed to share the same roots as the [[ArmoredTrooperVOTOMS Overmen]], an ability that exists so that humans may protect themselves from "[[BiggerBad Ba'al]]".
* "The Abyss" is a rupture in the dimensional boundary line that connects the various UCW, ADW and other worlds. It only opens at specific times and conditions, but allows safe passage between worlds with correct timing. ''[[Anime/MobileSuitGundamSEEDDestiny The Eternal]]'' battleship is able to use it to travel to the ADW on instructions from [[GenesisOfAquarion Gen Fudou]], who appears to be the only person capable of moving between worlds at will. The Abyss is also responsible for triggering the Anti-Spiral's "[[ApocalypseHow Human Extinction System]]". Because the Abyss is currently acting as a conduit between the UCW and ADW, the system calculates both worlds' human populations together. With a combined total exceeding ten billion (rather than one million from ''Gurren Lagann''), it initiates the second phase.
* Every person with access to the Black Knowledge is trying in their own way to resist fate:
** [[ShinMazinger Dr. Hell]] wants to conquer the ADW so he can use all of Earth's means to fight against it.
** Wiseman wants humanity to evolve through conflict in order to fight the Ba'al and, failing that, [[spoiler:for Chirico to inherit his powers and knowledge to fight in his stead]].
** Lord Genome knows that the Spiral Nemesis is part of the Ba'al, thus works with the Anti-Spiral to suppress all Spiral beings.
** Charles and [[CodeGeass V.V.]] aim to [[AssimilationPlot convert all of humanity into a single consciousness]] so they can survive it.
* It appears the Zero System is also part of the plans created by [[Anime/MobileSuitGundam00 Aeolia Schenberg]]. This implies the system was designed over 200 years ago along with [[MobileSuitGundam00 VEDA]]. In a way, this appears to be a {{Homage}} to the Creator/IsaacAsimov ''{{Foundation}}'' trilogy, where the Zero System functions as the "Second Foundation" or backup for VEDA should the plan ever get derailed. On Stage 58 on the Believe Zero/Black Knights Route, once Tieria had gained control of VEDA, Ribbons was DangerouslyGenreSavvy to quickly board his Reborns Gundam and destroy Seravee before Tieria could finish using the Trial Field to shut down all the Gagas. However, Heero was able to use the Zero System to interface with VEDA and disable all the Gagas functioning as sort of a backup Trial Field which was something that Ribbons did not see coming. Heero also revealed a [[Gundam00AWakeningOfTheTrailblazer Gundam 00 Movie]] easter egg which identified Ribbons Almark as: '''''Code X1409 EA Ray'''''
** The [[MobileSuitGundamWing five Gundam professors put an end to the Libra and Quinze]] [[http://www.youtube.com/watch?v=cx0sIBXsN94 by activating the self-destruct mechanism of the satellite]]. Before they die, they reveal they used to work with Celestial Being but left due to some disagreement. The Zero System was initially conceived to work in tandem with the "[[MobileSuitGundam00 Twin Drive System]]".
* Kira has unique battle dialogue (while attacking and evading, possibly taking damage, too) when fighting [[CodeGeass Gino Weinberg]] and [[MacrossFrontier Brera Stern]], where he refers to them by name; Gino returns the favor (instead, he refers to Kira by his full name). All three characters are voiced by Creator/SoichiroHoshi.
* [[MacrossFrontier Mikhail Blanc]] doesn't think [[spoiler:[[Anime/MobileSuitGundam00 Lyle Dylandy]]]] is fit to replace Lockon since he isn't a dedicated sniper, more so since Mikhail takes it upon himself to pick up the slack after [[spoiler:Neil]] dies. Following the scenario where Mikhail, [[OvermanKingGainer Gain Bijou]] and [[spoiler:Lyle]] needed to destroy a Dimensional Beast from long-range, [[spoiler:Lyle]] comes through perfectly and decides he's fit to take over after [[http://www.youtube.com/watch?v=NifZP6DjGXM all]].
* The death of [[MobileSuitGundam00 Nena Trinity]] in ''Saisei-hen'' can occur in different scenarios depending on whether the player chooses to trust Zero or not. If the former is chosen, she dies in Scenario 51; if not, Scenario 52. What makes her death different from ''Gundam 00'' is Setsuna wonders what she's doing at the abandoned satellite where he's supposed to rendezvous with [[MobileSuitGundam00 Wang Liu Mei]] (in the anime, the appearance of the [[MobileSuitGundam00 Throne Drei]] was a surprise). [[spoiler:ZEXIS witnesses Nena assassinate Liu Mei as she proclaims the real relationship between Liu Mei and [[MobileSuitGundam00 Hong Long]] (in the anime, no one finds out about this)]]. Even her dying words are slightly different, [[spoiler:as [[MobileSuitGundam00 Louise Halevy]] tells Nena she knows she doesn't want to die this way AFTER dealing the lethal blow, while Nena is coughing up blood]].
* During Scenario 27, when the main ZEXIS force arrives, [[http://www.youtube.com/watch?v=_aFWZou7RZk attacking Heero in his Wing Zero with specific pilots will result in special dialogue where they either briefly manage to get through to him]] (resulting in Heero receiving a Will decrease) or enrage the Zero System further (Heero gets a boost in Will):
** Characters who decrease Heero's Will:
*** Quatre, Kamille, Basara
** Characters who increase Heero's Will:
*** Lelouch, Setsuna, Crowe
* [[{{Dancougar}} Emperor Muge Zorbados]] and Emperor Zul use the power of darkness to bring the [[{{Gravion}} Zeravire]] into the ADW, though the Black Knowledge may have some part in knowing how to create them.
* Getter Energy is what the Gods from Shin Mazinger use to power their armor.

* The [[ShowWithinAShow movie within a]] [[http://www.youtube.com/watch?v=N6GaIYxoO_0 movie]] from ''A Wakening Of The Trailblazer'' is parodied in ''Jigoku-hen'', with a unique map, characters and units (such as Mazinger, Gurren Lagann and Shin Getter), but is non-playable. InUniverse, viewers are under the impression Celestial Being has access to {{Super Robot}}s - if they see something like Godmars in RealLife, they'd believe it's part of the organization. ''Jigoku-hen'' also gives names to the pilots in the movie: Setsuna -> Michael; Lockon = Warren; Allelujah = Jennifer; Tieria = Olson.
** Almost all the ZEXIS walk away annoyed after watching the film, with Mikhail commenting he expected more of a documentary and Alto complaining about how the film depicts the [[MacrossFrontier VF-25 Messiah]]. The exception is Kouji, who's amused [[{{Foreshadowing}} the film version of Mazinger is a 200-meter tall giant of light]].
* [[http://www.youtube.com/watch?v=NyvJDYj9e8g In Scenario 9 of the Chase Route, every young member of your team really wants to help Sousuke and Chidori track down a mysterious pervert. Hijinks ensue, including randomly running into Ryouma and Viral. They find the Pony pervert who wears a horse head . . . who ends up running into Beastmen . . . who of course, are all piloting the horse headed Ganmen. After that, cue the debut of Bonta-kun here to save us from all of these ponies. Every girl is insanely jealous pony dude attacked Alto instead, turning him into a pony girl too Ryouma and Viral mistake Hibiki and Sousuke for the pony dude and attack them along with the FMP?F policewoman]]. [[http://www.youtube.com/watch?v=ffyBwdAGRlE In the Training Route, everyone is Rugby hell training with Sousuke, Bobby, Ryouma and Viral.]] [[TakeThatScrappy Katz Kobayashi gets Mao's training hell from her personally]]. Both routes introduce Bonta-kun, so you'll end up trashing the entire stage with Black Getter + Bonta-kun either way.
** [[http://www.youtube.com/watch?v=ffyBwdAGRlE The Rugby team decides to play Brockenball with Brocken's head.]]
** After the the battle on either route, Ryouma is hired by [[LightNovel/FullMetalPanic Jindai High]] as a security guard/assistant janitor. Apparently, adventuring doesn't pay all that much.
** Amalgam pops up a lot, working with Martial and Geminis and so on, and A21 and Sousuke tie in to the Endless Waltz stuff.
** Kamille, Banagher, Amata, Shinji, Alto and Kouji bust into the women's hot spring in a enactment of a scene from ''Full Metal Panic? Fumoffu''. However, Gates appears out of nowhere and ruins their fun.
** Beck and Kan Yu are now Gauron's lackeys in this game where those two will usually show up along with Gauron and maybe Gates. They also get Firebug to follow them because Gauron made them work for him and that they were out of a job.
** Chidori's whispered knowledge apparently gives her knowledge of black history; She's the first person to mention the Axis drop, before even Char mentions it. The ZEUTH people recall seeing this in the black history stuff back in Z1
* Due to LaserGuidedAmnesia, Z-BLUE cannot remember characters from any absent series in ''Jigoku-hen''. However, only memories in the combined world in this game are affected: when [[http://www.youtube.com/watch?v=QkphvyzMDj0 Kei and the Orguss arrive from an interdimensional rift]] into the world of ''Jigoku-hen'' does Z-BLUE recall he is their comrade. PlayedForLaughs regarding [[GenesisOfAquarion Apollo]] near the end of the game - when told he was a "dog", Z-BLUE agrees, a CallBack to his scruffy appearance and feral demeanor.
* As a parallel to his ''VideoGame/SuperRobotWarsAlpha'' counterpart, [[RebuildOfEvangelion Shinji Ikari]] converses with [[AquarionEVOL Mikono Suzushiro]] about feeling "useless", yet Z-BLUE actively praises Shinji's efforts, such as the [[http://www.youtube.com/watch?v=qnHlOjKcGVY&feature=gp-n-y fight]] against [[RebuildOfEvangelion Ramiel]]. [[RebuildOfEvangelion Misato Katsuragi]], who's usually around with the ''Dai-Guard'' characters, has [[Anime/DaiGuard Shunsuke Akagi]] [[http://www.youtube.com/watch?v=ShmegGI0IsA become]] Shinji's BigBrotherMentor in ''Jigoku-hen''.
* [[http://www.youtube.com/watch?v=mIdzq_iQp60 Heero]] and [[http://www.youtube.com/watch?v=p9CwQAvPct0 Chirico]] each use the Bonta-kun suit once, on different routes; Heero remarks that it doesn't suit him, and ends up returning it to Sousuke.
** Heero saving Sousuke's teacher in the hijacking scene
** Heero, Sousuke and Chirico [[http://www.youtube.com/watch?v=0bnWqJsN_m8 "......"]] conversation.
** At onw point, Chirico goes after Fyana with CC. Teitania shows up, they fight. Gauron is working with the cult from Shining Heresy. Chirico is wary of Fyana's safety so he leaves her with the cult.
* [[Gundam00AWakeningOfTheTrailblazer Graham Aker]] takes a page from [[MobileSuitGundamWingEndlessWaltz Zechs Marquise]] and calls himself [[MobileSuitGundamWingEndlessWaltz Preventer]] "Lightning", a ShoutOut to Zechs' own Preventers CodeName "Wind". If Graham is in a support attack with Zechs, he'll refer to the latter as ''Fujin'' ("God of Wind") and himself as ''Raijin'' ("God of Thunder").
* When the [[MobileSuitGundamWingEndlessWaltz Mariemeia Army]] kidnaps [[MobileSuitGundamWingEndlessWaltz Relena Darlian]], they also take with them [[CodeGeass Nunnally vi Britannia]]. This leads to Zero and [[CodeGeass Suzaku Kururugi]] infiltrating the Brussels Presidential Bunker and saving the hostages.
** As a CallBack to the ''Second Z'', Zero is the one who talks [[MobileSuitGundamWingEndlessWaltz Chang Wufei]] out of his HeroicBSOD following the events of ''Endless Waltz''.
* Shin Mazinger plot is takes ideas from ''Manga/ShinMazingerZero''. They speculate what would happen if Kouji loses control of the Mazinger and if the Photon Power kept leaking. on that note Zeus battle was fun, they also mention Tetsuya again and Yumi mentions of a possible another dimension Mazinger existing in their world. because Brocken had to run from a battle against a Mazinger and he wanted revenge against Kouji ( 2nd stage event) so he attacked him, Kouji notes that he doesn't understand why Brocken wants revenge, Sayaka reminds him he did beat [[spoiler: Dr.Hell who went into hiding]]. Oh and [[spoiler: Viscount Pygman is dead]].
** It turns out that all the rank and file Mycenaeans were killed by Gaiou, [[spoiler: he DIDN'T kill Hades and the 7 Generals]]
** Hades and Zeus appear in the present time because Baron Ashura kills him/herself.
** Hades said that if Z-BlUE can't beat the Kedora made with the brains of the Invaders, how could they hope to beat the Baal army?
** At some point, Mykage's forces will attack Hades' and vice versa.
** At one point, Kouji has a hard time against Hades. Go and the Shin Dragon shoots him with Getter Rays and Mazinger Z powers up.
* As a ShoutOut to ''Zeta Gundam'', Kamille becomes upset when a student from the karate club at Jindai High [[http://www.youtube.com/watch?v=qRV7EC85is8 calls him a girl]]. He proceeds to beat him senseless, a reference to him doing the same thing to [[MobileSuitZetaGundam Jerid Messa]].
** Rather than use the Zeta Gundam, Kamille begins ''Jigoku-hen'' as a test pilot for the [[MobileSuitGundamUnicorn RGZ-95 ReZEL]] by [[MobileSuitGundamUnicorn Anaheim Electronics]], and is partnered with [[MobileSuitGundamUnicorn Riddhe Marcenas]]. Since the [[MobileSuitZetaGundam Anti-Earth Union Group]] is no longer needed, its members have been absorbed into [[MobileSuitGundamCharsCounterattack Londo Bell]].
* Since [[MobileSuitZetaGundam Katz Kobayashi]] survived the events of ''Z'', he returns in ''Jigoku-hen'' as part of Londo Bell and becomes a BigBrotherMentor to [[MobileSuitGundamCharsCounterattack Hathaway Noah]]. In contrast to his ''Alpha'' counterpart being TheScrappy, Katz has matured and is less obnoxious about others, particularly about Char being ObviouslyEvil with regards to [[MobileSuitGundamCharsCounterattack Neo Zeon]].
* Neo Zeon in ''Jigoku-hen'' is primarily based on Char's faction from ''Char's Counterattack''. This causes problems with [[MobileSuitGundamUnicorn Marida Cruz]], as she comes from the original Neo Zeon faction created by [[MobileSuitGundamZZ Haman Karn]] in ''MobileSuitGundamZZ'', which doesn't appear in the ''Z'' series. Instead, Marida is more or less a "[[SuperPrototype prototype]]" of [[MobileSuitGundamZZ Elpeo Ple]]; her history as a sex slave is glossed over.
* InUniverse, conspiracy theorists state the [[MobileSuitZetaGundam Mineva Lao Zabi]] representing Neo Zeon is a fake because she's too young, given the time frame between ''Z'' and ''Jigoku-hen''. Naturally, any person who has read ''Gundam Unicorn'' or watched its AnimatedAdaptation knows [[spoiler:[[MobileSuitGundamUnicorn Audrey Burne]]]] is the ''real'' Mineva.
* Mykage uses the Vajra as mooks because Mykage brainwashed the Vajra with his song.
** Mykage kidnapped Ranka and Sheryl in one of the NGE missions and proceeds to use their songs to power the Evil Aquarion in a later scenario. An angry Basara says that their songs have been twisted by Mykage.
** Jin's first contact with women are the one in Z-BLUE He thinks that all women are immortal, that they are able to command the battle while drunk and violent, and that they are hard to understand.
** Jin [[spoiler: isn't trapped in a frog]], and Kagura and Zessica are actually be allowed to interact so Zessica getting over Amata for Kagura will actually not be forced and contrived.
** The original Aquarion was stored in Central Dogma within NERV along with Lilith.
* The Z-BLUE pays a visit in Paradigm City, which results in Aoi vs Schwarzwald, then Gunbuster to the rescue.
** Roger essentially reverts to living out the dream state he was in during Episode 14/the first episode of Big O Season 2. Hobo Roger spends a good part of the game wandering around Paradigm until Dorothy finally finds him, he suddenly remembers who he is, and he becomes Roger the Negotiator once again.
** Big Venus is involved with the incident 12,000 years ago that Zero and Gendou and other people who actually know what's going on talk about. [[spoiler:Paradigm City is supposedly a trial run of the time prison. The wasteland outside the dome is the result of the nuclear winter caused by a parallel Char's Axis drop.]]
** Big Venus came into conception because that jerk Gadlight managed to give Angel that "push" to go ahead with it.
** Big Venus works like Zonuda. It deletes your units after the fight.
* In the [[TengenToppaGurrenLagann Alternate Space]] [[LotusEaterMachine Labyrinth]], Z-BLUE experiences their idealized world. In a twist, the Labyrinth forces ''Gundam'' characters to experience nightmares; for the most part, the worst elements from their shows' respective canon storylines:
** Setsuna in despair
** Shinn' fury over Kira
** Amuro and Char bickering against one another during the Axis ColonyDrop
** Heero being given the order to assassinate Relena
** [[MobileSuitZetaGundam Paptimus Scirocco]] successfully {{Mind Rape}}s Kamille before he dies
* Ryouma shoots Simon with Getter Beam to give him a power boost needed to combine into the Chouginga Gurren Lagann
* As per its series, the eponymous TengenToppaGurrenLagann is the size of a galaxy. To justify how the rest of Z-BLUE can fight the Anti-Spiral and the similarly, galaxy-sized [[TengenToppaGurrenLagann Grand Zamboa]], [[TengenToppaGurrenLagann Spiral Power]] affects all of their respective HumongousMecha, rendering them into galaxy-sized versions of their normal units. This is designated in-game with an infinity symbol as unit size.
** Alternate Armageddon Ryoma mentions that the [[spoiler: UCW Getter Team has "vanish[ed]"]]
** [[spoiler: Axis just fulfills yet another of Ba'al/Anti-Spiral's attempts to drop something onto earth]] and gives Simon his moment where he promises Nia to save her and we get to see the real Nia for a short moment.
* If Ryouma, Kouji or Simon engages the Anti-Spiral, dialogue reveals [[spoiler:the latter is an ally of the [[ShinMazinger Mycanae Empire]] and is supposed to guard the titular "time prison" to ensure organizations like Z-BLUE does not exist]].
* ''Jigoku-hen'' is the first [=SRW=] since ''VideoGame/SuperRobotWarsCompact'' the FinalBoss is not an OriginalGeneration ([[Characters/SuperRobotWarsZ Shikuu]] is the PostFinalBoss), but the Anti-Spiral with the Grand Zamboa, due to it being the authority behind a "battalion" of the Ba'al, having half of the antagonists in the game under its command. Essentially, ''Jigoku-hen'' is a lead-up to the encounter with the Anti-Spiral.

[[folder:Tropes]]
* ActorAllusion: The [[{{Grendizer}} Vegan Empire]] {{Mook}}s in ''Z'' are voiced by NobuyukiHiyama, and will often quote "Courage won't work here!", a reference to his earlier role as the Gai Shishiou from ''{{GaoGaiGar}}''.
** Reportedly, several others wanted to do the role of the Vegan {{Mook}}s but, when told it was Hiyama doing it, they gave up and said something along the lines of "[[OvershadowedByAwesome We can't compete with that!]]".
** Like [[VisualNovel/{{Tsukihime}} Aruceid]] [[Creator/RyokaYuzuki Brunsted]], Suzune also has a SplitPersonality.
* FandomNod: As a nod to the streamer who placed Katz in the Zeta Gundam during his stream, one of the DLC scenarios (Mr. Z-Blue) has Katz in the Zeta Gundam.
* FanNickname: See [[FanNickname/{{VideoGames N-S}} here]] for the entries
* HeyItsThatVoice
** The Edel Bernal is [[VisualNovel/SchoolDays Makoto Itou]]; the people at [=NicoNicoDouga=] had a field day with this.
** Gaioh is [[SoulEater Lord Death]]
** Shiony Regis is [[ElfenLied Lucy]]; also shares the same voice with [[GenesisOfAquarion Reika/Hong Lihua]] and [[MacrossFrontier Catherine Glass]], [[TalkingToHimself who are also present]] in ''Hakai-hen''.
** Marguerite Pistail is [[SoulCalibur Taki]]
** It appears [[ModernWarfare Soap]] is now in command of an Eldritch Abomination.
* NamesTheSame
** Rand is neither related to nor an {{Expy}} of country-music singer Music/RandyTravis.
** By the ''Second Z'', there are two types of "[[OvermanKingGainer Over]][[AMechByAnyOtherName men]]" and "[[ArmoredTrooperVOTOMS Over]][[{{Ubermensch}} men]]". Additionally, one must make a distinction between the Black Knights of ''Code Geass'' and the [[{{Dancougar}} Black Knight]].
** "[[Anime/CodeGeass Guren]]" and "[[GurrenLagann Gurren]]" are similar enough that Kallen and Kamina fight over the naming rights when they first meet.
** The final attack for the Li-Brasta is called "Unbreakable Fulcrum". Whereas the Li-Brasta B's version is a WaveMotionGun, Li-Brasta R's version involves RammingAlwaysWorks.
* TheOtherDarrin: A notable case with a few of the debut series - Olson and [[Anime/SpaceWarriorBaldios Flick]] (two roles originally done by the late Creator/HirotakaSuzuoki) are voiced in ''Z'' by Creator/KenyuHoriuchi and Creator/KeijiFujiwara, respectively; Fujiwara also voices [[GodSigma Gagan]] due to death of Mikio Terashima. Likewise, Creator/TakumiYamazaki and Creator/TomokazuSeki takes over the roles of Marin and Toshiya for the late Creator/KanetoShiozawa and Creator/KeiTomiyama. Averted in the case of [[MobileSuitGundam Bright Noah]] and [[{{Daitarn 3}} Banjou Haran]] (two other Suzuoki roles) as ''Z'' reuses old audio clips from previous [=SRWs=].
** In ''Hakai-hen'', Creator/IsshinChiba voices [[Anime/ArmoredTrooperVotoms Baiman]] in place of the late Creator/KanetoShiozawa, whilst Saisei-hen has Creator/KentaMiyake in take of the roles of [[Anime/ArmoredTrooperVotoms Bully]] and [[Anime/GetterRobo Stinger]] from the late Creator/DaisukeGori.
** In ''Jigoku-hen'', Creator/KenjiUtsumi recorded lines for [[Anime/ShinMazinger Hades]] before his passing, but not [[Anime/{{Gigantor}} Uchuu Maoh]], thus Creator/YusakuYara provides his voice for the latter.
* WhatCouldHaveBeen
** The ''Baldios'' storyline continues after its "[[DownerEnding interesting ending]]" in its home series and goes into the movie plot, suggesting this is how it was supposed to be all along. ''Z'' makes a note of this in Baldios' encyclopedia entry.
** Files uncovered after ''Z'' was hacked include Amuro's voice files for supporting [[Anime/MobileSuitVictoryGundam Usso Evin]] and [[Anime/MobileSuitGundamZZ Judau Ashta]] in combat. Considering the things current [=SRW=] producer Takenobu Terada has said in the annoucement of ''Hakai-hen'', both were probably considered, but only ''MobileSuitVictoryGundam'' is implied to be in a future game and ''MobileSuitGundamZZ'' seems to have been dropped due to story issues (it can't happen if the ''Zeta Gundam: A New Translation'' trilogy occurs) and the agenda NamcoBandai and Creator/{{Sunrise}} has for it.
** Furthermore, the voice data files for ''Z'' include quotes for Amuro and other Gundam characters using the [[Anime/MobileSuitGundamF91 VSBR]], and [[Anime/UFORoboGrendizer Rubina and Maria Grace Fleed]] calling out the names of {{Mazinkaiser}}'s weapons.
** Bosses in the ''Second Z'' have unused special quotes when fighting against Cheval Reptail, which suggests he might have been intially planned to be a SecretCharacter.
** ''{{Patlabor}}'' was supposed to make its debut in ''Jigoku-hen'', but the development team decided to put them into ''Super Robot Wars OE'' instead.
