* SugarWiki/AwesomeMusic: [[https://www.youtube.com/watch?v=1JuAFiNmuNg The main title]] is suitably epic.
* BrokenBase: Fans of the show generally can't decide amongst themselves whether Femur is an [[TheScrappy obnoxious line-stealing distraction]] from the main plot, or a much needed comic relief character in an otherwise nihilistic cosmic horror series.
* 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 WesternAnimation/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? [[WesternAnimation/TransformersTheMovie Deja vu]].
%%* ToyShip: Pyrus and Zera.
* TheScrappy: Lord Mantle is a warmongering {{Jerkass}} whose attempts to usurp leadership of the Alliance from Graveheart and establish Rock as the supreme power in the Cluster only make things worse for the Alliance. Granted, it seems he was an ''[[HateSink intentional]]'' example.
