* {{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 ''CharsCounterattack'', but as her VA was unavailable for the film, this didn't materialize.
* BizarroEpisode: "Prelude ZZ" 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: Rakan Dahkaran, Neo-Zeon's answer to Yazan Gable, who shoots down hospital ships, kills [[spoiler:Mashmyre and Hayato]], fires on civilians, and changes loyalties the instant he believes he's found someone stronger than his current employer.
** In the manga, [[spoiler:Glemmy]] definitely fits the bill. He lacks the sympathetic qualities his anime counterpart had (for example, his crush on Roux) and is immediately shown to be a serious threat - in sharp contrast with Mashmyre, who retains his AntiVillain characterization - and to be coldly manipulating Ple. At the end of Volume 1, [[spoiler: we are shown Ple being cruelly brainwashed in order to make her into a subservient weapon. When a Neo Zeon scientist expresses concern for the girl's life, Glemmy dismisses him as "too soft", and when Judau manages in DefusingTheTykebomb, Glemmy sorties to kill Ple himself. He doesn't manage to, but still...]] And in Volume 2, it gets worse: [[spoiler:in an attempt to lure out the Nahel Argama, Glemmy has civilian villages bombed and massacred, and when the Nahel Argama crew does intervene, Glemmy sends out Ple-2 to kill Judau and Ple - and she does manage to kill the latter.]] When, during the final battle, [[spoiler:Judau calls him out on his actions, Glemmy just smirks and tells him that a few sacrifices have to be done for a lofty goal such as the reconstruction of the Zabi family. Of course, Judau tells him to shove it.]]
* ContestedSequel: It's not ''[[Anime/MobileSuitZetaGundam Zeta]]'', and it's attracted quite a bit of backlash for that.
* 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.
* FanonDisContinuity: As far as some fans are concerned, this series never happened. Then again, others will take ZZ over A New Translation any day. Whatever.
* FanDumb: Quite a number of Western fans delude themselves that Tomino never directed the first half, apparently unfamiliar with ''half'' of the mans works.
** It's not so much that he didn't direct period, it's just that he had a far less "hands-on" approach to it due to him pitching ''CharsCounterattack'' at the time.
** Definitly applies to Zeta fans when it comes to this series who disregard it simply for not being Zeta.
** There's also a huge amount of Char fans that hate [[TeenGenius Glemmy]] [[TheStarscream Toto]] and claim he is a failed CharClone. While Glemmy does have parallels to the darker sides of Char, his character mainly relates to Gihren Zabi from {{Mobile Suit Gundam}} so much so that it's even [[LampshadeHanging lampshaded in the series]]. A few Haman fans also get angry that Glemmy threatened to steal her thunder as well.
* MagnificentBastard: There is Glemmy Toto, who along with having [[HiddenAgendaVillain his own agenda]] and managing to keep it under wraps until the big reveal, flies up the ranks quickly in order to get close enough to Haman. And managed to [[TheCharmer charm her for a while]] too. Only to use his new status and popularity [[TheStarscream to form his own faction]], [[ManipulativeBastard giving a riling speech to the people of Zeon to motivate them to fight for his side]]. He [[NobleDemon also believed in handling things in a sophisticated manner]]. His ultimate goal is [[WellIntentionedExtremist to see Zeon united under the Zabi rule]], believing their method to be the most successful. He tried to accomplish this not only by winning the crowd over, but also [[MadScientist creating clones]] to [[TykeBomb use as military weapons]], being one of the first [[BigBad big bads]] to use clones in the ''Universal Century''. And although he was ultimately defeated by Judau and Roux, his actions did make an impact on Zeon while he was alive. And he managed to accomplish all of this ''[[TeenGenius at the mere age of seventeen]]''.
** Haman Khan fits the trope, though her personality is significantly different from Glemmy's. While she's not quite as deceptive as Glemmy, this is mainly stylistic; she's equally skilled at politics and able to effectively play her enemies off against each other. In addition, her [[NervesOfSteel strength of will]] is beyond question; she is willing and [[{{Badass}} more than able]] to take to the battlefield when it's called for, whether on foot or in a mobile suit, and she once stood down an attacking mobile suit with bladed hands and didn't even blink. She makes it clear that her goal is to bring the Earth Sphere under her jackbooted heel, and while she doesn't win, she outlasts Glemmy's rebellion against her.
* MoralEventHorizon: The Dublin Colony Drop serves as one for everyone involved: Haman Khan (who orders its implementation), Mashmyre Cello (who aims it), to Rakan Dhakaran (who guns down those trying 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 mom and grandmom of all [[TranquilFury tranquil furies]], with anger and power strong enough to ''cause Haman a FreakOut'' and be felt by Newtypes who were ''far'' away from the place. '''That is how massively pissed off he was''', and it's scary to see.
* 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?"
* TakeThatScrappy: Judau's first meeting with the much-despised [[ZetaGundam 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?
* 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 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.
