* SugarWiki/AwesomeMusic:
** "Cantata Orbis", the closing music from ''Be Invoked''. Though we must consider on how ironic the lyrics meant, as how it portrays [[spoiler: glorification of life and God]], all the while [[spoiler: when all the characters are already dead in the end]].
** No love for the opening and ending?
** "[[https://www.youtube.com/watch?v=D_cGHNoKSKc Overwhelming Power]]". When you heard it, you know that [[spoiler: anyone who opposed Ideon is just good as dead.]]
* EarWorm: "[[https://www.youtube.com/watch?v=TIcYvE231q8 Fukkatsu no Ideon]]," the ([[SoundtrackDissonance rather peppy]]) opening.
-->"SP-PACE RUN-A-WAY IDEON! I-DE-O-NNNNNN!!"
* EsotericHappyEnding: [[spoiler: Everyone dies in the most cruel and tragic way, including women and children, after which the explosion of Ideon destroys a huge chunk of the galaxy. And then... the child of Karala and Bess becomes a real messiah and leads the souls of the dead supporters of her mother and father to the newly reborn Earth, where they will be reborn in the new world as Gundam characters. Yes, this is also MindScrew as it sounds.]]
* FridgeHorror: Just how many times has the Ide [[ApocalypseHow pushed the reset button]]?
* HilariousInHindsight: Mechas called the Dogg Mack and [[VideoGame/ZeroWing 'Take off every Zigg Mack']].
* ItWasHisSled: One of the most well known parts of the series is its ending.
* MemeticMutation: '''Ideon destroyed the universe!'''
** [[NeverLiveItDown Which is kinda odd because it only destroyed the solar system it was in/that part of the galaxy it was in.]]
** [[TakeAThirdOption Okay, let's just say it destroyed humanity.]]
** Hey, look at the monitor to your left. [[FourthWallPsych *Stares at troper*]]
** Frequently, Doba's manly-tears-closeup near the end of ''Be Invoked'' is a standard [[ImageBoards imageboard]] reply to something awe-inspiring.
* NightmareFuel: A lot of the deaths in the show (as you can see [[https://www.youtube.com/watch?v=GiFPvqnzK9g in this video]]) and especially the movie Be Invoked, are pretty gruesome, but what takes the cake is [[spoiler: the death of [[HeartwarmingOrphan Ashura]], who [[OffWithHisHead gets her head cleanly blown off.]] ''And she's a kid of a mere 5 years.'']]
* [[NiceJobBreakingItHero Nice Job Breaking The Universe Heroes]]: Well duh.
* HilariousInHindsight: So, as Ideon and Anime/{{Macross}} essentially have the same idea, but told it in a tragic and correspondingly optimistic way, it can be quite fun to watch the first brutally scoff at the idea of ​​PowerOfLove victory over xenophobia and the war between two different peoples.
* NarmCharm:
** Even now, fans can't decide if Cosmo's massive afro is really hilarious or really awesome.
** If you've heard the ending of the series before watching it and started to watch this show in our time, its absurdly excessive cruelty, especially in combination with the old-fashioned anime, can get very much into this trope. Up to the point that it will be perceived as an evil parody of the old MechaGenre.
* SeinfeldIsUnfunny: At the time, DownerEnding and MindScrew were so shocking and depressing in this show that ratings began to fall sharply, and the studio reduced the number of episodes. Now his despair is more likely to be treated as MemeticMutation and NarmCharm because of his nature of the "strange old mecha show".
* SoOkayItsAverage: The movie is really the main reason this show stays on the map, as it was where most of the over-the-top violence and the KillEmAll ending actually played out. The actual show isn't terrible, but the episodes are StrictlyFormula and rather cliché-ridden, and [[OffModel the animation budget]] wasn't exactly huge.
* TropeCodifier: For the philosophical SpaceOpera with esoteric GainaxEnding and war DownerEnding. For the latter, this is probably one of the most vivid and memorable examples in anime, taking into account the eastern tragedy and sadness.
* WhatDoYouMeanItsForKids: Turning a children's show with robots into an extremely tragic-depressing version of Romeo and Juliet with one of the most famous DownerEnding in the history of anime, was obviously not a good idea. But it worked and made this anime a legend, yes.
* WhatDoYouMeanItsNotSymbolic: [[spoiler:Cosmo and Kasha name Karala's child Messiah.]]
* WhatAnIdiot: Karala's reckless actions in the first episode causes so much grief for the human main characters and kick-starts the plot.
* WTHCostumingDepartment: Reviewers on the Internet have pointed out how Buff Clan generals' uniforms resemble [[HilariousInHindsight stereotypical Elvis impersonators' outfits.]]
** They're more than likely meant to invoke the look of alien warlords from the days of Flash Gordon and other 30s serials.
