Femur's arrogant, wheedling, and manipulative nature hardly befits his status as Emperor of the Imperial Bone Empire. Yet, Femur is a fitting ruler for a planet where the most cunningly manipulative and deceiving individuals procure royalty status. Despite having Femur as their leader, the people of Bone are known for their bravery and ferocity in battle. Weak willed, and blindly arrogant, Femur looks for whatever options will best benefit him personally. His trust is constantly tested by the alliance, however he can be incredibly persuasive at times, unfortunately, it is usually for selfish reasons.

Pelvus Young and opportunistic, Pelvus is Femur's second-in-command. Since assassination is the only means of promotion on Planet Bone, he is constantly trying to do away with Femur so he can ascend to the Throne. Femur is well aware of Pelvus' plans and constantly tries to stay one step ahead of him.

The Bone Warriors are fierce and brave fighters and unlike their half hearted ruler Femur, never run from conflict. Dedication, strength and stamina are necessary characteristics for Sternum soldiers, however, intelligence is not. To make up for their lack of intellect, Planet Bone scientists have created 'Smart Suits', armored combat suits that are endowed with artificial intelligence. These suits enable warriors with better decision making abilities in battle, often nudging or suggesting courses of action. A symbiotic relationship exists between the suits and the weapon systems that the Sternum Warriors carry. This relationship allows the suit to maintain and rearm the weapons properly, something that warriors would normally have a great deal of difficulty with. In battle, smart suits have been known to act in very bizarre and unpredictable ways, even having been witnessed carrying off dead or disabled warriors to safety while still continuing to fire at enemies. The Sternum Warrior / Smart Suit combination is a highly efficient and powerful weapon in any combat situation.
