* DesignatedProtagonistSyndrome: Humble, level-headed Graveheart is easily the least interesting member of the ensemble.
** There's a reason why this is under YMMV, yes he is humble and level-headed almost to a fault, but the fact that he remains that way even after basically becoming the de-facto leader of an ''entire solar system'' is what makes him so fascinating to many fans.
* GeniusBonus: As with all MainframeEntertainment productions, classic quotations and references abound throughout the series, particularly in episode titles. ''J'accuse'' deals with a murder accusation against respected soldier Jade and ''Ragnarok'' brings about the end of the traditional Cluster society. As with ReBoot and WesternAnimation/BeastWars, Mainframe shows that being a children's show does not mean intelligence is left at the door.
* HilariousInHindsight: A sci-fi CosmicHorrorStory about an unstoppable mechanical EldritchAbomination where the heroes have to unite a divided galaxy to fight the looming threat? [[Franchise/MassEffect Sounds familiar]].
** A mechanical monster planet whose first shown act is eating a world of living robots, only to have their one survivor deliver exposition on its identity to the heroes later? [[TransformersTheMovie Deja vu]].
