** [[Anime/MazinkaiserSKL The Machine Island]] was a research center for alternative energy sources established after World War II (tying into the plots of both ''Gundam 00'' and ''The Wings of Rean''). It produces an ore called Odyssite, which is critical to the Original story and has similar properties to [[Anime/NinjaSenshiTobikage Kilhacium]], [[Anime/MacrossFrontier Fold Quartz]], the [[Toys/BBSenshiSangokuden Dragon Seal]], and Anime/TheWingsOfRean.

** [[Anime/FafnerInTheAzureDeadAggressor Festum mind reading]] works on the [[Toys/BBSenshiSangokuden SD Gundam units]] despite the fact that it only works on humans due to their genetic similarity, [[spoiler:hinting at the fact that Militia is EarthAllAlong.]]

** [[Anime/FafnerInTheAzureDeadAggressor Festum mind reading]] works on the [[Toys/BBSenshiSangokuden SD Gundam units]] despite the fact that they were only supposed to work on humans, [[spoiler:hinting at the fact that Militia is EarthAllAlong.]]

* NothingIsScarier: The Riot X that only appear in the penultimate stage. Almost nothing is known about their origin other than that they were presumably [[spoiler: made by Noble Dylan in a previous cycle]]. Despite their resemblance to the prior Riot models, they weigh dozens of tons less, and their pilots fight in complete silence, making it ambiguous whether or not they're even human.

** The higher dimension that the [[Anime/FafnerInTheAzureDeadAggressor Festum]] have been trying to reach by returning the universe to nothing is speculated to be the world beyond [[[VisualNovel/{{Demonbane}} Yog-Sothoth's gate]], where the Great Old Ones, who were described by Al as beings of nothingness, dwell.

** Tatsumiya Island is a part of [[Anime/MobileSuitGundamSEEDDestiny Orb Union]].

** Fei-Yen's plot is tied in with Mazinkaiser SKL, since she was found underneath Kiba's fortress and was later revealed to have been summoned there by the Gravity Engine. Once you go on a route split she has an encounter with Miku[[labelnote:*]]Note that in game she never mention Miku's name[[/labelnote]] and gets her KYUNKYUN beam, then during SKL finale she goes super mode[[labelnote:*]]which is basically Fei-Yen's original SuperMode[[/labelnote]] when Kiba shows up, and during Fafner TV finale, she gets her Morale boosting special command. So, ''In the Blue Sky'' is unlocked during ''Operation Azure''.

* TokenEvilTeammate: [[Manga/LinebarrelsOfIron Miu Kujou]], true to her [[KnightTemplar potrayal]] in the source material, is notably the only teammate who disagrees with UX trying to make peace with the Festum and the Vajra and allying with the Katou Organization. She even comments that [[spoiler: humanity is one step closer to activating the self-destruct switch]] after [[spoiler: the battle with the Festum ended]].

* WeHaveBecomeComplacent: As part of the ''Manga/LinebarrelsOfIron'' plot, [[spoiler: there is a self-destruct switch in the human gene that activates when humans lose their imagination, which ended up happening when they achieved artificial immortality through nanomachines]]. Trying to stop this from happening is what motivated every major faction in ''Linebarrels''. Of course, the heroes reject the idea that [[spoiler:peace equals death]] and vows to find a better way.

** [[Manga/LinebarrelsOfIron The Human Machina]] kept the time loop in place because of [[spoiler: Kali Yuga]]

** It's eventually revealed that [[spoiler:[[Toys/BBSenshiSangokuden Militia]] is an iteration of Earth where the [[Manga/LinebarrelsOfIron Humanoid Machina]] successfully evolved into humans. [[Anime/{{NinjaSenshiTobikage}} Planet Ladorio]] is also a past version of Earth, and the actions of the ninja warriors in the present day turns out to be the source of Ladorio's ancient ninja legend.]]

** [[Anime/MazinkaiserSKL The island covered by the gravity curtain was apparently a research center]] for gravity engine cores since World War II (a key plot point to ''The Wings of Rean'').

* NiceJobBreakingItHero: In ''UX'', ALL of the aliens respond to Denton's message which include the Festum, Vajra, ELS, Human-Machina, Skrugg, and [[VisualNovel/{{Demonbane}} Anticross]]. [[spoiler:In ''Heroman'' finale, it's shown that that's not the case: the Skrugg were called to the ''wrong'' Earth by the same message which called the main cast.]]

** Fei-Yen's plot is tied in with Mazinkaiser SKL, where it is the robot used by the female kingdom. She starts out really reserved, then once you go on a route split she has an encounter with Miku[[labelnote:*]]Note that in game she never mention Miku's name[[/labelnote]] and gets her KYUNKYUN beam, then during SKL finale she goes super mode[[labelnote:*]]which is basically Fei-Yen's original SuperMode[[/labelnote]] when Kiba shows up, and during Fafner TV finale, she gets her Morale boosting special command. So, ''In the Blue Sky'' is unlocked during ''Operation Azure''.

* EvolutionaryLevels[=/=]UnroboticReveal: The Franchise/SDGundam[=s=] here are actually humans from the far future who've evolved into Gundams.

* HealingFactor: All the SD Gundam units have HP regen due to being living beings. The ''Linebarrel'' Machinas also regenerate health, but unlike in ''[[VideoGame/SuperRobotWarsL L]], they regenerate health every time they're hit in addition to the passive regen every turn.

* HealingFactor: ''Linebarrel'' units regenerate health once hit.

* GuideDangit: It's hard to tell what's a step for unlocking a secret character and what carries over to later playthroughs.
