* CrowningMusicOfAwesome: 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=GPmJPMzKFmM english intro]] 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]].

* 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.
** His [[spoiler: HeelFaceTurn]] near the end of the series, his sincere grief and regret over his actions when [[spoiler: Shadow is killed]], and his PetTheDog moments with [[spoiler: Reese]] probably have a lot to do with this as well.
* EnsembleDarkhorse: O'Connell has quite the fanbase in the US despite having a relatively minor role.
* FanNickname: "Guardian Force" for the Post-TimeSkip episodes. These episodes were still officially titled "Chaotic Century".
* FirstInstallmentWins: Most fans agree that the best storyline and CharacterDevelopment happens in this series. The others have their charm but are not as respected. As always however, Your Milage May Vary.
* HilariousInHindsight: In one instance Fiona is caught by one of Rosso and Fiola's henchmen, who comments that she's cute and will be a "real knocker in few years." Come the timeskip in Guardian Force, we see he was right on the money.
* 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://t3.gstatic.com/images?q=tbn:ANd9GcQtw9Ipmxw3-rIWheHUnIZYOgewm9P4C24fTnc6Kk0g-My6Qz3JHQ Hiltz when he]] [[http://oi41.tinypic.com/2unycur.jpg merges with the]] [[http://oi39.tinypic.com/fmjp1g.jpg True Death Saurer's Core.]] 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.
** [[spoiler:It gets better though, in the form of a Mid Season Upgrade]].
** To this Troper, Rudolph's blood-curdling scream when [[spoiler: Van's Shield Liger gets destroyed]].
* TooDumbToLive: Van's Shield Liger's E-shield is almost never used.
** Rosso and Viola's romantic exchange in the cockpit of an Iron Kong before it gets electrocuted to hell by Raven's Geno Saurer.
* ToyShip: Van and Fiona in Chaotic Century.
