Grey is one of the Ziraxia characters.
He is a tall, muscular, and very old member of his own alien race (only known as the Greys). He is usually seen as a hologram. He is the cruel, demanding commander of the Ziraxians' ship. He is the only crew member whose position is higher up than X-captain Zira.
He is a white humanoid with black eyes and a skull-like head and a goatee. He wears a black-gray cloak with a gold belt and is sometimes seen riding a scooter that flies through space.
