Lamprey is a master of deceit and subterfuge who weakens worlds from the inside out through complex gambits, occasionally pausing to murder people who cross her path for little other reason than to amuse herself. Lamprey introduces herself tricking Emperor Femur into installing a device meant to drain all the life from Planet Bone. After this, Lamprey possesses Tekla and tries to use her to destroy the Alliance from the inside out, contenting herself with subjecting her to horrific Mind Rape of her planet's destruction and trying to slowly kill her from the inside once this fails. After this fails, Lamprey murders a resident of Planet Fire and pins it on Jade's hands, intending for her to be horribly executed by being dipped into a fall of lava. Lamprey's final crimes in the series stem purely from petty spite: Seeking revenge against Tekla, Lamprey has her Beast drones attack a bar with the intent to kill everyone inside, personally disintegrates Captain Blaze once he gets in her way, and furiously attempts to kill everyone who stands between her and Tekla before her own demise.
Blokk is a brutish warrior who firmly believes in the power of absolute force over everything else, preferring to overrun worlds through his armada to destroy all they see whilst basking in the carnage. Blokk's repeated attempts to attack the planets in the Cluster result in numerous deaths and the successful destruction of Planet Jungle. Blokk personally attempts to trick Cryos into killing his own daughter whilst leaving his planet vulnerable, and grows more and more vicious after his repeated punishments at the hand of the Beast. In the finale of the series, Blokk takes over Planet Rock by force by besting and killing Lord Mantle, while promising to give the Alliance members he's captured—two children among them—a slow death at the Beast's hands. Once he's left stranded on Rock, Blokk slaughters his way to Rock's World Engine, personally executes Feldspar, and sets the entire planet on a collision course with the nearest star out of sheer spite.
Darkness-Induced Audience Apathy: Nothing the heroes do has any chance of destroying the Beast Planet; if anything, they kill as many innocent people as it does.
Genius Bonus: As with all Mainframe Entertainment 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 Beast Wars, Mainframe shows that being a children's show does not mean intelligence is left at the door.
What Do You Mean, It's for Kids?: A Cosmic Horror Story... aimed at kids. Tons of horrific imagery, violence, death, and the onscreen obliteration of entire planets and their inhabitants beside the general premise. Even the ending is depressingly bleak, although this is more fault of being Cut Short.
