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 Alliance travels to planet Bone but finds a surprise – the Beast planet is already there. Emperor Femur, an arrogant and egotistical leader, agreed to welcome both the Beast and the Alliance on his world. Lamprey the Deceiver and her agents convince the Bone Emperor to side with them and send on the run King Cryos, Graveheart, Jade and prince Pyrus. The young prince of Fire believes he can reason with Femur but is captured by Lamprey and her warriors. Eventually it is revealed that the field generator built on planet Bone will not protect the planet but will instead seal the entrance to any Alliance Battle Fleets. When betrayed, Femur rescues Prince Pyrus and creates a diversion allowing the Aurora to destroy the Field Generator giving their fleets the chance to swarm the invaders. Bone joins the Alliance. Back at their World Fortress, Lamprey tells Blokk and Voyd that she believes Tekla to be responsible for uniting the worlds.

Lamprey possesses the body of Tekla and intends to crush the fragile Alliance by murdering its leader Graveheart. Her plan fails when she mentions details the real Tekla couldn't know. She escapes inside Femur's flagship heading back to Bone.

Tekla and Lamprey battle for the domination of Tekla's body and spirit. Tekla manages to defeat her enemy and regains control of herself.

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.

Captain Blaze and his renegade squad steal one of the Battle Moons and attempt to regain their lost honor in destroying the Beast Planet. But when Blokk and his battle fleets almost seize Prince Pyrus, Captain Blaze returns to save his young lord. At the command center, Jade is contacted by Lord Mantle to finish their bargain.

The Alliance travels to planet Sand. Lady Zera meets one of the Sand People, Zuma. She is a telepath. In the end, the great Sand People save the day with their mind power.

Jade, princess Tekla, Lady Zera, Pelvus and Zuma head for "Moon Over Mayhem" to socialize. In an attempt to reconcile, Tekla gives Jade the key of the Cluster defenses. During this pleasure trip they are attacked by Fire's pirates and smugglers as well as Lamprey and her drones.
