Lodestar

Lodestar is the Omnitrix DNA sample of a Biosovortian from an unknown planet.

Appearance
Lodestar has a floating metal head which levitates between his shoulders, however, it is still bonded to his body as wherever his head goes, his body follows as shown in Video Games. He has crab-like claws for hands and his body is mainly black with yellow feet, hands, shoulders and chest. His mouth rarely moves, even when he's talking.

In Omniverse, Lodestar has two spikes on his head and new head shape. He also has lines beneath his mouth and his mouth now moves when he talks. The white glow around his head is now green. The yellow from his feet go up to his thighs. His chest and shoulders are bigger and the yellow stripes by his chest are shorter.

Lodestar wears the Prototype Omnitrix/Ultimatrix/Omnitrix symbol on his chest.

Powers and Abilities
Lodestar is able to project magnetic waves that are capable of overloading electrical circuits and attract metal, he can also emit magnetic pulses that allows him to magnetize any metal objects. His magnetic pulses in Alien Force/Ultimate Alien are white, but green in Omniverse.

Lodestar can generate a green electromagnetic force field that protects him from most ballistic attacks.

If Lodestar is destroyed he can easily pull back the fallen pieces. As seen in Ultimate Aggregor he can regenerate if he is destroyed. He can levitate and fly.
