Lodestar is the Omnitrix's DNA sample of a Biotsavartian from the planet Maxwell.
Lodestar has a magnetically floating metal head surrounded by a glowing white aura and levitates in an arch between his shoulders. He has crab-like claws for hands (similar to Brainstorm (Ben 10)'s) and his body is mainly brownish-black with yellow feet, hands, shoulders, and chest. His body is also made of living alien metal.
In Omniverse, Lodestar has a yellow eyebrow-like crest on his forehead, which looks similar to that of Jetray. His head is more skull-shaped with has lines beneath his mouth. The glowing aura around his head is recolored green, the yellow from his feet go up to his thighs, his shoulders are now larger, and the yellow stripes by his chest are shorter.
