Staroid

Staroid can radiate destructive lightning, and fire power blasts from his arms. Staroid's top segment of the star on his back can detach and transform into a boomerang of destructive energy. He has the ability to transform into a large metal sphere. As a sphere, Staroid is practically invulnerable to any attack. Staroid was chosen to lead the Machine  Empire's initial invasion due to his battle prowess. He initially overwhelmed the Zeozords until they combined into the Zeo Megazord. Staroid was destroyed by the Zeo Megazord's Saber.
