Shadow Raiders - Season 1 - Eps 4: Bad to the Bone
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.
