When Trey and his ship/zord, Pyramidas were shot down by alien bounty hunters, Trey was injured and Pyramidas was damaged. So Trey passed his Gold Ranger powers to Jason. Feeling he left Jason at a disadvantage without Pyramidas, Trey sent Warrior Wheel for Jason to use as his zord until Pyramidas was repaired. Warrior Wheel has a Two modes, Wheel Mode (left) in which he rolls into enemies to destroy them, and Warrior Mode (right) in which he can fight along side the Zeo Megazord. Warrior Wheel presumably is still in storage in the Zeo Zord holding bay.
