* Almost everyone who actually gets to play ''VideoGame/SuperRobotWarsUX'' will agree the story astonishingly brilliant, so much that its popularity now only rivals ''VideoGame/SuperRobotWarsW'' (too bad for those from the state side). One of the main props is that ''UX'' has one of the largest SecretCharacter cast in recent SRW titles (''almost all'' canon deaths can be saved), and if you manage to save them the scenerio will drastically change afterwards (some even up till the epliogue); meanwhile there're just "oh god how many" crossovers between different series to the point that they're all smoothly written. Some of the best moments will be explained in the following lists.
* After being mistreated in ''VideoGame/SuperRobotWarsK'', the ''[[Anime/FafnerInTheAzureDeadAggressor Fafner]]'' cast finally receive their justice, filled with awesome moments here and there...Some along with [[Anime/MobileSuitGundamSEEDDestiny Shinn Asuka]] and his [[MemeticMutation Mark Destiny]].
** Stage 25. When Kazuki is in a pinch defeating those Festum on Tatsumiyajima, Shinn also joins the fray to protect Yumiko (who is about to get killed), but his Impulse gets heavily damaged in the process. However, before Shinn gets assimilated (even telling Kazuki, who rushes in to help him, to get away so that he can protect more people) we hear Tsubaki's whispers, and she ''remotely delivers the newly repaired Destiny Gundam'' to Shinn's hands, who proceeds to rip Festums apart together with Kazuki...All happens along the song ''Life Goes On''.
--->'''Tsubaki:''' It's fine, the destiny is on your side...And since it's your answer, this is the wings of fate you hoped for!
** Stage 27 ([[Anime/TheWingsOfRean Byston Well route]]) is a '''major''' one, but only if you fulfill requirements to save Shouko Hazama: [[Anime/TheWingsOfRean Rouri Yahan and Kanamoto Heiji]] are beating up your team badly with their new Aura Battler, but suddenly Soushi receives a familiar signal in Siegfried System, and out there comes no one but that supposed-lost Mark Sechs and Shouko, who ''outright curbstomped Rouri on spot''. To put it into perspective, ''Fafner'''s resident ill girl [[TookALevelInBadass has been level-grinding]] so much that she's now known as [[MemeticMutation a skillful female Aura Battler]]. Suddenly the stage's title "Earthlings' Aura Power" (and her name) instantly leads to a whole new meaning.
*** The next stage involves [[Toys/BBSenshiSangokuden Koumei Re-GZ]] seeing through [[Anime/TheWingsOfRean Sakomizu's plan]] and asking [[VisualNovel/{{Demonbane}} Al-Azif]] to lend him the Mirror of Nitocris, allowing him to recreate the infamous "Empty City Strategy" to ensure Sakomizu's flagship's guns are occupied, while Lockon (directed by Shuuyu Hyakushiki) takes out said flagship's main cannon before it can recharge. It then follows that up with Sousou Gundam [[TheReasonYouSuckSpeech taking Sakomizu to task]] for his overreliance on trickery.
--->'''Sousou Gundam:''' This is what you hail for your dream, Sakomizu? Sacrifices are permissable, but one who only relies on evil plans and trickery will not become a real king!
** Stage 29, Shinn and Lunamaria rush out to save the ''Fafner'' cast as they try to persuade Koyo Kasugai to regain his humanity (if Shouko is alive, she'll pitch in too), and revealing their new CombinationAttack in the progress. Luna then states she'll bear Shinn's responsibility to protect those around from being harmed, as she is now his partner. It also gets heartwarming when you realize [[Creator/KenichiSuzumura the]] [[Creator/MaayaSakamoto two]] actually get married in real life.
*** The after-stage Lantern Flow scene (which used to lament for the dead) is a minor SugarWiki/MomentOfAwesome, as the scene will run differently depending on your routes taken, and if you saved someone before. To a surprise for ''VisualNovel/{{Demonbane}}'' fans, Leica will also lament for her brother Ryuuga. This is BIG, because their origins and relations were cut out in the anime, while only one route in the original VisualNovel will mention it. Clearly the staff has ShownTheirWork.
** In Stage 38, to prevent Tatsumiyajima being nuked, Mamoru becomes such a {{Determinator}} that he ''nearly kills [[Anime/TheWingsOfRean Sakomizu]]'', who're just going to activate Oukaou's SuperMode, and ''impressing'' him, of all things. Unfortunately [[Anime/NinjaSenshiTobikage Hazard Pascha]] [[KickTheDog kills Mamoru seconds later]], [[MoralEventHorizon despite the fact that he is protecting his frigging nuke-carrying ship the whole time]]. Such act just gets Sakomizu (and your teammates) understandably and mightily pissed. Oh, and Mamoru does all these, as of original, ''without his Goubain helmet''.
*** Mamoru also gets one later in Stage 41 if you manages to save him. The new Fafner pilots and your team are facing the assault of the new Festums, and the rookies are understandbly shaken, but Mamoru pulls out a BigDamnHeroes along with a RousingSpeech and ShoutOut to ''Manga/KamenRiderSpirits'', and conduct a CombinationAttack with Hiroto Douma (too bad it doesn't get animated).
--->'''Mamoru:''' Even there're no chance of victory, one will still fight for he believes that tomorrow will come...That is what known as Goubain!
--->(Cue CombinationAttack)
--->'''Mamoru:''' There're still many enemies out there...But yet it's not a problem, for me and Hiroto are now Double Goubain!
** Stage 39, we finally come to Operation Azure. If conditions are fulfilled, Michio Hino will pull out a BigDamnHeroes to save [[Anime/NinjaSenshiTobikage Irubora]] from Idun, to repay Irubora's act of saving his life earlier. But the real awesome moment? ''Not only'' does Maya take advice [[Anime/Gundam00AWakeningOfTheTrailblazer from]] [[Anime/MacrossFrontier resident]] [[Manga/LinebarrelsOfIron snipers]] to take out Idun near the end, and ''not'' only do the the Earth Federation's forces (specifically, [[Anime/Gundam00AWakeningOfTheTrailblazer Kati's troops]]) help with your assault, but also ''Fei-Yen HD'', who finally fully awakens, sings ''[[VideoGame/VirtualOn In the]] [[MeaningfulName Blue Sky]]'' to give your team HeroicSecondWind to defeat Idun once and for all. (Which actually becomes obvious if one understands [[{{Foreshadowing}}how to pronounce "39" in Japanese.]])
* Stage 4. [[Anime/NinjaSenshiTobikage Tobikage]] [[BigDamnGunship comes out of nowhere]] and BEATS UP '''[[VisualNovel/{{Demonbane}} Master]] [[BigBad Therion]]'''. No more explaination is needed.
* Stage 22 can be alternatively called as SugarWiki/MomentOfAwesome: The Stage. Your team is still [[HeroWithBadPublicity the enemy of the whole world]] despite fighting so hard against [[Manga/LinebarrelsOfIron Katou Organization's satellite weapon]] ''and'' their alien reinforcements, freakin' [[Anime/NinjaSenshiTobikage Hazard Pascha]] is about to become Commander-In-Chief of all Federation's forces, [[ShoutOut the democracy seems dying out]] [[Film/RevengeOfTheSith with the thunderous applause among the council]]...Until [[Anime/MobileSuitGundamSEEDDestiny Arthun]] (who pulls off his [[PaperThinDisguise Alex Dino disguise]] almost exactly the way and the words [[Anime/MobileSuitZetaGundam Quattro Bagina]] used) and [[Manga/{{Heroman}} Agent Hughes]] arrive on time, reveals that Hazard is actually betraying everyone and giving him a proper verbal smackdown before the President relieves Hazard from duty [[note]]as she doesn't have enough evidence to prove said treason to relieve him until this moment[[/note]]. She then immediately contacts your team and calls on them to do something about the aforementioned satellite weapon, preferrably something martial. Now your team (which up to this point is mostly regarded as an antagonistic mercenary group) finally becomes the force of justice!
** That's just half of the awesomeness. [[Anime/DancougarNova Eida]] fought very hard for the first 22 stages so that her companions can live their ordinary life (it's a long story), but now (at the same time as of the above events) she also reaches her limit and is about to get killed......But suddenly, a mighty cry resounds: '''"[[CombiningMecha CHOUJUU]] [[PreAssKickingOneLiner GATSHIN!]]"'''[[note]]Completely voiced, no less[[/note]] This signals Team D's reformation ''and'' your time to go on the offensive, ''while the game's main theme is playing''. The later half of the stage we'll see your team ''and'' Earth Federation race to destroy the nukes flying in the air, which is also an awesome thing to watch.
* Remember the [[Manga/LinebarrelsOfIron Final Phase scene]] from ''VideoGame/SuperRobotWarsL''? Well, now play Stage 45. If you fail to save Ishigami, he'll pull out a HeroicSacrifice as of in the manga; BUT if you manage to save him, Sakomizu and Ryofu Tallgeese, here's how it works: the group's under heavy attack from the Human Machinas, when all of a sudden Sakomizu returns to the field along with Ryofu, and they waste no time in kicking those Machinas to the curb (in Sakomizu's case, he'll reveal his CombinationAttack with Asap while he's at it); and when Ishigami is about to pull his HeroicSacrifice anyways, Shinn, Kira and Athrun convince him to live on so he can create a new future, and try to destroy the portal ([[FridgeLogic which brings out the question that why Mobile Suits' power output can be that high]]), and followed by EVERYONE (including Jin) pitching in to help them. To put the final nail in the portal's coffin, Ryofu, Ryuubi, Sonken and Sousou unleash their mightiest CombinationAttack (previously only seen in their series' manga), and everything ends with Ishigami and Katou's attack on the last of the Human Machinas. Oh, and even though Linebarrel's story in ''UX'' isn't from the anime, ''[[SugarWiki/AwesomeMusic PROUD]]'' is played all along Ishigami's scenes. [[LampshadeHanging Ishigami's words afterwards]] really drives the point home, though:
--->'''Ishigami:''' The future has been changed......Well Juda, seems that even you can't predict things like this, huh?
** A minor SugarWiki/MomentOfAwesome for Creator/JojiNakata (Ishigami's VA): he ''actually'' wrote on his Twitter that he wanted to voiceover those famous lines from the manga before Ishigami's HeroicSacrifice, and he got to do so.
* [[Anime/Gundam00AWakeningOfTheTrailblazer Setsuna and his 00 Qan[T] ]] doesn't get a lot of time to shine in the movie, but in ''UX'' his 00 Qan[T] rolls out much earlier, we finally get to see it in action. Its debut in Stage 38 involves trying to convince [[Anime/TheWingsOfRean Sakomizu]] to stop his conquest, telling him not to be trapped by the past events; and in Stage 43(Tatsumiyajima route), Setsuna actually ''uses the Quantum Burst'' on [[Manga/LinebarrelsOfIron Hisataka Katou]] so he can understand what his respected teacher (Amagatsu Kizaki) really means to save the world. One can say that the success to direct Amagatsu's last words from Kouichi to Katou makes Setsuna confident that he can do the same to ELS.
* Stage 49, you finally get to put [[Anime/NinjaSenshiTobikage Hazard Pascha]] out of everyone's misery for good. Admit it, after all those [[KickTheDog dogs he kicked]] and plummeting gleefully across the MoralEventHorizon, "satisfying" doesn't even enough to describe one's feelings upon his death. (At least in ''UX'', anyway)
* Stage 50 wraps up the last of ''Anime/MacrossFrontier''. As the possessed Queen Frontier is about to blast the Macross Quarter to bits with [[{{BFG}} its Macross Cannon]], a large cluster of Vajra, drawn in by Sheryl and Ranka's songs and emotions, return to [[TakingTheBullet block the shot]] as of original...''But it doesn't end there''. In fact, [[Anime/Gundam00AWakeningOfTheTrailblazer ELS]] '''and''' [[Anime/FafnerInTheAzureDeadAggressor Festum]] also rush to help protect your force: living proof that the attempt for coexistance does not, and will not end in vain. Your force then proceed to beat the living crap out of those Cyber Nobles, ending with the infamous Wing's Dance to end the war against Vajira.
