* {{Asspull}}: Sayla's involvement in the series often gets this response due to lack of foreshadowing or explanation to her actions. It is heavily suggested that her appearance was meant to foreshadow a role in ''Anime/MobileSuitGundamCharsCounterattack'', but as her VA was unavailable for the film, this didn't materialize.
* BaseBreakingCharacter: Beecher and Mondo's ChronicBackstabbingDisorder in the early portion of the series rubbed some fans the wrong way, especially because it was often PlayedForLaughs. This is a side effect of the first half of the show being LighterAndSofter than the predecessors. As explained below, viewers tolerance for the antics of the duo was really determined by how much they liked the early tone of the series.
* BizarroEpisode: "Prelude ZZ", the ''very first episode'', has no particular plot and consists of a long stream-of-consciousness recap and foreshadowing mixed in with occasional acid trips and mobile suit quizzes.
* CompleteMonster: While LighterAndSofter than earlier works, especially ''[[Anime/MobileSuitZetaGundam Zeta]]'', ''ZZ'' still has this duo:
** [[SociopathicSoldier Axis-Zeon]] AcePilot [[ColonelKilgore Rakan Dahkaran]] was an {{expy}} of ''Zeta's'' Yazan Gable, and, like his inspiration, a [[TheBrute brutal]], [[ImplacableMan nigh-unkillable]] BloodKnight with a [[IFightForTheStrongestSide tenuous grasp of personal loyalty]]. Cold-blooded and willing to do whatever it takes to get the job done, Rakan has no qualms about harming civilians. This is best demonstrated in Episode 35, where he [[TheStoic impassively]] [[KickTheDog guns down hospital ships and evacuation craft]] fleeing the Dublin ColonyDrop, and destroys roads and bridges in order to make sure that nobody escapes the blast radius. He kills longtime ''Gundam'' veteran Hayato Kobayashi when the latter tries to stop him, and, following his defection from Haman Khan's forces, willingly kills many of his old comrades, including [[AntiVillain Mashmyre Cello]] and Royal Guardsman Lance, before being stopped by Judau. Axis's go-to guy for the dirtiest of jobs, Rakan proves that in the end, his only loyalty is to himself.
** While the anime version of [[TeensAreMonsters Glemmy Toto]] had enough redeeming traits to keep him off this list, the same cannot be said for [[AdaptationalVillainy his manga counterpart]], a vicious SmugSnake and [[TheStarscream Starscream]] who is bad news from his first appearance to his last. Coldly manipulating Puru, an unstable ChildSoldier, into doing his killing for him, Glemmy keeps a small army of brainwashed clones of her as backup for when she inevitably dies on him. He burns down a village to draw out [[TheProtagonist Judau Ashta]], has a defecting Puru [[WouldHurtAChild killed]] by her EvilTwin Puru-2, and eventually [[TheStarscream betrays]] [[BigBad Haman Khan]], triggering a devastating EnemyCivilWar in the process, as he aims to make himself the dictatorial ruler of both Earth and the colonies, unleashing his entire clone army in the process. Idolising the franchise’s original CM, [[Anime/MobileSuitGundam Gihren Zabi]], [[YouClonedHitler whose DNA]] may [[ApocalypseHitler run in his veins]], Glemmy promises to be every bit as brutal a tyrant as he was, and betrays no concern at all for the dozens of little girls who are dying to make his dream a reality.
* ContestedSequel: It's not ''[[Anime/MobileSuitZetaGundam Zeta]]'', and it's attracted quite a bit of backlash for that.
* DracoInLeatherPants: Haman's fans are divided between those who LoveToHate her and those who want to turn her into a hero, marry her, or both. She's already a highly sympathetic character, but there are those who take that too far and forget the part where she's a mass-murdering MisanthropeSupreme dictator. With the Gundam video games, this has [[RunningTheAsylum translated]] into cases of AdaptationalHeroism.
* EnsembleDarkhorse: Elpeo Ple, who is also one of the first lolicon characters in anime history.
* EvilIsSexy: Haman Karn and Chara Soon, though with contrasting styles.
* {{Fanon}}: A rather popular in its day theory says that [[spoiler: Glemy isn't Gihren Zabi's clone, ''but his bastard child''. The whole "clone" deal would be false, for two possible reasons: either Glemy a) claimed to be a clone to to disguise his true heritage as Gihren's child ''and'' the other Zabi descendant (aside of his "cousin" Mineva) from enemies; or b) it was a lie that he came up with as a youngster to psychologically protect himself from such a burden, and then he himself came to believe it as he grew up.]] It ''does'' provide for a rather interesting AlternateCharacterInterpretation, though.
** Years before, Yoshiyuki Tomino confirmed in interviews with Animedia and B-Club magazines that Glemy was Gihren's son with an unnamed Newtype woman. He also confirmed that Ple and Ple-Two were "artificial[=/=]unnatural twins" whose parents were Gihren and a different Newtype woman, meaning they're half-siblings, which adds a new layer of {{Squick}} to those scenes where Ple-Two acts romantic towards Glemy.
* FanonDiscontinuity: Fans who were less than happy with ''ZZ'' eagerly latched onto the CompilationMovie version of ''Zeta Gundam'', whose ending was incompatible with ''ZZ'', as proof that it had been kicked out of canon. [[WordOfGod Tomino himself said]] this wasn't the case, and the ''Zeta'' movies were merely another take on the events. This was supported by ''[[Anime/MobileSuitGundamUnicorn Gundam Unicorn]]'', which features not only several ''ZZ'' mobile suits, but a character closely tied to that series as well.
* HilariousInHindsight: There's an online quiz out there that lets you construct your wolfkin name by matching your first and last name to two wolf-related words. Due to the word Moon appearing in both lists, it's possible to be named ''Moon Moon'', which has even led to MemeticMutation.
** Speaking of the Moon Moon, a race of people who live on the moon and prefer peace when possible, and the protagonist crossdressing at one point? [[Anime/TurnAGundam Sounds familiar.]]
* MagnificentBitch: Axis warlord and Neo-Zeon RegentForLife Haman Khan came closer to conquering the Earth Sphere than any of the despots to come before or after her in the UC timeline. Intervening in ''[[Anime/MobileSuitZetaGundam Zeta Gundam]]'''s Gryps Conflict on the side of Paptimus Scirocco's Titans, Haman helped turn the battle between the AEUG and the Titans into a full scale civil war within the Earth Federation, a war from which she emerged as the one true winner following Scirocco's death and the obliteration of the Titans and most of the AEUG. Invading the Earth before the Federation could recover from the war, Haman occupied huge swathes of the planet, and used the Dublin ColonyDrop to terrorize Federation officials into surrendering to her, all while employing sheer force of personality to mask her myriad personal issues and hold the backstabbing house of cards that was Axis-Zeon together. Betrayed at the zenith of her power by Glemmy Toto, and faced with internal rebellion by his supporters, Haman quickly moved to quell the descent, meeting Glemmy in open battle. Confronted by series' protagonist Judau Ashta, Haman was persuaded that humanity did not, in fact, need her jackboot on its throat to [[WellIntentionedExtremist stop them from killing each other]]. The only UC BigBad self-aware enough to come to grips with [[MisanthropeSupreme what she had become]], Haman [[DrivenToSuicide killed herself]] in the name of giving the world a better future.
* {{Moe}}: Ple and her clones.
* MoralEventHorizon: The Dublin Colony Drop serves as one for most of those involved: Haman Khan (who orders its implementation), Mashmyre Cello (who aims it), Rakan Dakharan (who guns down the civilians attempting to flee it), ''and'' the Federation officials (who leave their own citizens behind to die in it.)
* NightmareFuel: Ple and Kamille go utterly ''batshit'' when Dublin is destroyed via ColonyDrop. The split-second image of Ple, who was not in the best mental health to begin with, spasming in terror is one of the most unnerving images in the entire franchise. At least for some people.
** Also, what happens when [[spoiler: Haman shoots Leina]]. Judau, normally a HotBlooded kid, completely '''snaps''' in the mother of all [[TranquilFury tranquil furies]], with anger and power strong enough to ''cause Haman to FreakOut and literally cry in fear'' and be felt by Newtypes who were ''far'' away from the place. (The visualization was a demonic phantom emerging out of him. [[Anime/MobileSuitGundam The last time this happened]], it was [[AFatherToHisMen Dozle Zabi]] [[YouShallNotPass doing it]].) '''That is how massively pissed off he was''', and it's scary to see. This scene is probably why some consider Judeau to be the Newtype with the strongest raw power.
* RetroactiveRecognition: ''Gundam'' fans who started with later shows and worked their way backwards might find themselves asking "Why does [[Anime/MobileSuitGundamWing Dorothy]] have purple hair?"
* TheScrappy: Emily Ounce gets a fair bit of hate because her character does nothing except obsessively pursue Bright despite knowing that he's HappilyMarried to Mirai (when her subordinate Milly points this out, Emily simply glares daggers at her). This obsessive crush even results [[spoiler: in her eventual death,]] but most fans felt much sorrier for the Anaheim employees who had to put up with her crap and [[spoiler: almost got killed alongside her.]]
* SpecialEffectFailure: When [[spoiler: Rasara Moon]] dies, she's ''supposed'' to be crushed by falling debris beforehand, but due to an animation error, the debris lands a few feet away from her, making it look like she just fell on Mondo and died for no reason.
* TakeThatScrappy: Judau's first meeting with the much-despised [[Anime/MobileSuitZetaGundam Wong Lee]] ends with the former kneeing the latter in the gut.
* TooDumbToLive: In early episodes Judau does not follow orders of repairing the Zeta Gundam just because he doesn't like being ordered. Guess what nearly happens the next time he fights?
* ToughActToFollow: The show is a direct follow-up to ''Zeta''. Needless to say, fan reactions tend to be divisive. See ContestedSequel above.
* VillainDecay: Yazan. After being the resident CompleteMonster of ''Zeta'' and miraculously surviving the final battle thereof, he's subjected to repeated embarassment at the hands of the ''ZZ'' cast before being forced to [[DroppedABridgeOnHim leap from a flying mobile suit]]. With a ''poncho'' for a parachute. You could almost feel sorry for him... almost.
** Actually, he makes a couple of [[DemotedToExtra blink-and-you'll-miss-it cameos]] after this, so he may have at least managed to pull a KarmaHoudini.
** Especially considering [[spoiler: he manages to kill one more significant member of the Argama crew]] before the decay sets in.
** Fanon tries to explain this away as a combination of oxygen deprivation (after being shot out of his suit at the end of Zeta) and hunger (being forced to live like a bum for a majority of his appearance). That might make his situation AFateWorseThanDeath.
*** As of ''The Return of Johnny Ridden'', he's gone back to being a bloodthirsty AcePilot, so this definitely counts.
* VindicatedByHistory: Gundam ZZ has started to get some love, namely in ''Anime/GundamBuildFightersTry'', [[spoiler:a Puru clone]] in [[Anime/MobileSuitGundamUnicorn Unicorn,]] an entire Gundam Evolve short about what Judau's up to sometime after ZZ, and Judau shows up as a CoolOldGuy in various spinoff mangas.
