Haloid

Darkus Haloid is an ancient Vestroian Bakugan, imprisoned in the Doom Dimension for centuries as a forgotten scapegoat. He serves Yumeí as a guardian bakugan to gain his freedom-and former strength-from his prison. He seeks to one day repay the suffering he was forced to undergo to the one who falsely accused him.

Description
Haloid is a long, black snake with large, feathered wings and arms. A spined purple crest rests on top his head, and a long, jagged purple slash across his chest. He wears a golden collar around his neck as a power inhibitor.

Haloid is a very calm, logical being. He prefers to thnk things through, acting as a guide for Yumeí at times where her impulsive nature runs away with her.

Trivia

 * Haloid's design concept was taken from the Aztec serpent deity, Quetzalcoatl.
 * The world Haloid literally means "derrived from Halogen".
 * Haloid doesn't truly evolve; he regains his former strength, transforming into other forms that more closely resembles his true form.
