Shadow Raiders

With the destruction of planet Tek, the sole survivor, princess Tekla accompanied by Voxx travels to another system to warn all planets about the Beast Invaders. She crash lands on planet Ice where a quarrel between the Royal legion of King Cryos confronts a Rock expeditionary mining squad, including Graveheart. A Beast cohort launches a full-scale attack and only the Ice sovereign, Graveheart and a convalescent Tekla survive the first purge. King Cryos and his aides heal their former adversary and welcome Graveheart in joining the Alliance. Meanwhile, the Beast Armada invades the system and begins preparations.

The Aurora, Cryos' flagship, travels to planet Rock to convince Lord Mantle to join the Alliance. Sadly, the army arrests Graveheart and the Rock King expels the Ice King determining he is still his greatest enemy. Lord Mantle condemns Graveheart to imprisonment. Meanwhile, Blokk the supreme warlord of the Beast launches an invasion on planet Rock with Voyd permission. Jade, a rock commander and a long time friend of Graveheart, releases him and they run to the Core central to activate the planet's defense – the Battle Moons. They succeed but Lord Mantle banishes the “miner” still not believing in the alliance. Despite all odds, Jade agrees to join them, claiming to need to watch her friend's back.

The Aurora travels to planet Fire in hope of convincing prince Pyrus to join them. The obstacle here is the Grand Vizier who doesn't trust strangers. He orders Graveheart and King Cryos to survive a labyrinth of lava where lava dogs are lethal beasts. Meanwhile, Zera, Cryos' daughter, is furious at prince Pyrus for not intervening but a Beast battalion interrupts their argument and wounds the young lord of Fire. However, Jade arrives at the last moment and saves the children. Graveheart and Cryos survive the test and Fire is pleased to join the Alliance.

The Beast Planet demonstrates its might, launching an armada to attack Fire while training its powerful cannons on the Battle Moons. A stray blast threatens to destroy Ice, but Tekla and Lady Zera discover world engines hidden within the planet, which move it out of the path of the blast.

The Beast Planet targets planet Fire. Graveheart and Tekla must hurry to find the world engines. During the invasion, Graveheart is injured while saving prince Pyrus. The Grand Vizier witnesses the sacrifice and reconsiders his judgment towards the outlanders. In the end, everything is lost for planet Fire but the Grand Vizier sacrifices himself and tells prince Pyrus that his new friends are indeed worthy ones. Prince Pyrus orders the Vizier to evacuate with the rest of his people, because he still needs his guidance and company. The Vizier disobeys, saying that Pyrus is old enough to rule, and that the Vizier does not want to die a coward. The Grand Vizier uses the world engines to ram Planet Fire onto the Beast Planet's claw, hoping that it will destroy the Beast Planet, The Beast Planet consumes planet Fire anyway, killing the Grand Vizier.

Emperor Femur and Pelvus must make good their commitment to return to the Alliance. They agree to feed all the people of the Alliance with the resources of Bone, and so Bone rejoins the Alliance.
