* SugarWiki/AwesomeMusic: The music for the anime is some of the best around, and it's used frequently for non-fiction history and military shows in the US.
** The [[https://www.youtube.com/watch?v=ilGmh8auaeA intro for the English dub]] really gets your blood pumping.
** The best example for Crowning Music Of Awesome in the anime would probably be [[http://www.youtube.com/watch?v=07cNDoNinww this]].

* BadassDecay: Reese gets hit with this pretty hard towards the end of the series. For most of her appearances, she's a competent warrior and a constant threat with her piloting skills and ManipulativeBitch schemes. However, once Hiltz disposes of her and she starts traveling with Raven, she's demoted to a sideline position where she can't do anything for the final episodes other than cry and scream Raven's name.
* CaptainObviousReveal: The revelation that the [[RedBaron Baron of Wings and the Sword of Storms]] are Rosso and Viola should not come as a surprise, considering that they made no effort to disguise their voices or hide their faces, aside from black visors that barely covered anything.
* CommonKnowledge:
** Ask anybody familiar with this series, odds are they'll treat the post-TimeSkip episodes as a SequelSeries with the subtitle "''Guardian Force''", in the same vein as ''[[Manga/{{Naruto}} Naruto Shippuden]]'' or ''Anime/DragonBallZ''. The post-Time Skip episodes are in fact, just the latter half of ''Chaotic Century''.
** If they're not treated as two separate series, the pre- and post-Time Skip episodes will probably be referred to as "Season 1" and "Season 2", respectively. There was no break in the episodes when they originally aired, the Time Skip is just the start of a new story arc.
* CompleteMonster:
** [[BigBad Gunther Prozen]], the EvilChancellor of the Guylos Empire, keeps a pointless war with the Helic Republic going so that [[AmbitionIsEvil he can seize control of the Empire]]. Attempting to murder the child emperor Rudolph, Prozen sends his personal killer, a boy he indoctrinated from childhood named Raven, after him while also sending "rescue squads" that he has Raven destroy in order to cover himself while he continues the war. Prozen then attempts to awaken the ancient weapon the [[SealedEvilInACan Death Saurer]] and demonstrates its power by attacking his own capital. Even after defeat, Prozen adopts the identity of the Dark Kaiser with intention of re-awakening the Death Saurer and [[OmnicidalManiac wiping out organic life]].
** [[BigBad Hiltz]] is an Ancient Zoidian who [[KillAllHumans desires to exterminate all human life]] and rule Planet Zi himself. Initiating a series of terrorist attacks to destabilize the hard-won peace, Hiltz [[YouHaveFailedMe kills any men who fail him]] and even tries to kill his [[TheDragon right-hand woman]], another Ancient Zoidian named Reese, just because [[YouHaveOutlivedYourUsefulness she's no longer useful to him]]. Revealing his secret weapon the Death Stinger, Hiltz proceeds to bombard civilian targets and announces that when he proceeds to the Guylos Empire, he'll destroy every civilian town and city he sees along the way. Finally fusing with the Death Saurer, the sadistic Hiltz dedicates himself to exterminating all organic life on Zi, gloating how he will be the one to rule over everything.
* DracoInLeatherPants: Raven is an egomaniacal bloodthirsty killer who starts off as Prozen's attack dog, and later goes rogue and becomes a terrorist. He abuses and belittles Shadow, wants to commit genocide against all Zoids, and will even murder his own allies; yet we're meant to feel sorry for this jerk because he has a [[FreudianExcuse tragic backstory]]. Predictably, he has ''tons'' of fangirls.
* EnsembleDarkhorse: O'Connell has quite the fanbase [[GermansLoveDavidHasselhoff in the US]] despite having a relatively minor role.
* EpilepticTrees: Fans have speculated that an uncut dub for this series (as well as ''[[Anime/ZoidsNewCentury New Century/Zero]]'') exists in some capacity considering some of the slip-ups of swearing and blood occurring during it's American broadcast. Since the series has been absent from American shores for many years now, this may never be known. On the other hand, this is averted with the Latin American Spanish dub, since it was dubbed from the original Japanese version, albeit according with some sources, it was dubbed without taking into consideration [=ShoPro=]'s American branch rights over the whole region, including Latin America.
* FanPreferredCouple: Let's see... [[ImpliedLoveInterest VanxFiona]], [[CargoShip VanxZeke]], [[FoeYay VanxRaven, SchubaltzxO'Connell]], [[HoYay VanxIrvine]], [[TheLancer Irvine]][[CoolBigSis xMoonbay]]... Mind you, these are just the most common!
* FirstInstallmentWins: Most fans agree that the best storyline and CharacterDevelopment happens in this series. The others have their charm, but are not as respected.
* HilariousInHindsight:
** In one instance Fiona is caught by one of Rosso and Viola's henchmen, who comments that she's cute and will be a "real knocker in few years." Come the time skip, we see he was right on the money.
** Hiltz is very much similar to [[Franchise/{{Naruto}} fellow Akatsuki member]] Sasori, an EvilRedhead who have a scorpion-like machine (or doll in Sasori's case) as a weapon. They even share [[Creator/{{TakahiroSakurai}} the same Japanese voice actor]]!
%%* IdiotPlot: Chaotic Century suffers from a SERIOUS case, to the point where the plot moves forward not because of the skill or resourcefulness of the protagonists, but because of the stupidity of the villains.
* NightmareFuel: [[http://oi39.tinypic.com/fmjp1g.jpg Hiltz when he merges with the True Death Saurer's Core.]] [[http://oi41.tinypic.com/2unycur.jpg Which then starts sprouting the faces of the Death Saurer's previous hosts.]] Try to even describe what that looks like.
* TearJerker:
** When [[spoiler:Irvine's Command Wolf]] bites the dust after being hit by Raven's charged particle cannon. More specifically, the monologue that [[spoiler:Irvine]] delivers to the dying Zoid is what pulls the heartstrings.
** Rudolph's blood-curdling scream when [[spoiler: Van's Shield Liger gets destroyed]].
** The death of [[spoiler: Shadow. Raven's breakdown after shows that he really did care about his Organoid. Shadow was the only family he had left and now he's gone.]]
* TooDumbToLive: Van's Shield Liger's E-shield is almost never used.
* ToyShip: Van and Fiona in Chaotic Century.
