* AlternativeCharacterInterpretation: [[spoiler:Is the existence and identity of the Takeru we see in ''Final Extra'' really the [[VictoryGuidedAmnesia same one as that of the one we stuck with in]] ''[[VictoryGuidedAmnesia Unlimited]]'' and ''[[VictoryGuidedAmnesia Alternative]]'', or [[CessationOfExistence did the latter cease to exist after 00-Sumika dies]]? The members of the English-speaking fandom holds either the former or the latter position. In favor of the former: he slips into deja-vu in both ''FE'' and ''Altered Fable''. In favor of the latter: one of the game's emphases is that a person's memories and experiences make up his identity; he describes his eventual fate in the ''Extra'' branch (that of gradually-merging with that branch's Takeru) as effectively ceasing to exist.]]
* SugarWiki/AwesomeMusic: "Asu E No Houkou", performed by none other than Music/JAMProject.
** They come back with another banger in the form of [[https://www.youtube.com/watch?v=dllJF6zPE9I "Akatsuki No Ute"]] for the second opening.
* MemeticBadass: Ikaruga is the pinnacle of '''[[MemeticMutation YAMATO DAMASHII]]'''. He's "so Japanese that he's more Japanese than all of Japan and its lands and Shinto deities combined; people look at him and see the General of Generals, while BETA burst into flames just by being near him."
* MemeticMutation:
** The aforementioned '''[[PatrioticFervor YAMATO DAMASHII]]'''.
** age's AsianSpeekeeEngrish in ''Alternative'' and other related works, along with the quote "English can eat shit. I repeat, English can eat shit." For obvious reasons, most of the Engrish was corrected in the official localization, though the latter quote remained intact.
** The 33rd page of the 19th's chapter of the manga has [[https://external-preview.redd.it/cqdWWSgQZ7fwKyf4p2DjZYwhRLP16is1_eYo1eMu18A.jpg?auto=webp&s=4c03dfdd0216b895e98a19f770771e7cf0822d44 an infamous]] [[GagDub replacement]] of part of its text, usually accompanied by a ThreatBackfire-sort of reaction.
* OneSceneWonder: For all his popularity, Ikaruga only appears during one very short scene that isn't even really about him.
* TheScrappy: Naoya Sagiri is not a popular character in the fandom, to say the least. The reasons for this largely revolve around [[spoiler:his behavior during the coup arc]] and his behavior back in the world of ''Extra'', where he comes across as extremely selfish.
* SpiritualAdaptation: ''Film/PacificRim'' is the closest thing we could ever get to a screen adaptation of ''Alternative''. The amount of similarities that they share is ''staggering'', from the pilot outfit design to a plot point.
* SuspiciouslySimilarSong: The track [[https://www.youtube.com/watch?v=T63WnocViSU "Howling Spirit"]] tends to almost immediately receive comparisons to the "Anime/GunBuster [[https://www.youtube.com/watch?v=MxKhhMdbU5I March]]".
* TheyChangedItNowItSucks: The first opening to the anime adaptation was not well received, not because the song was bad, but because a lot of people found it extremely unfitting to the spirit of Muv-Luv Alternative. The production committee seems to agree, as the second opening is sung by Music/JAMProject ''and'' Creator/MinamiKuribayashi, to the hype of many fans.
