Power Rangers Zeo

After Master Vile turns back time and transforms the Rangers into children, they search across different eras for the pieces of the Zeo Crystal. Once time is restored, their old base is destroyed. In a newly built command center, they gain the power of the Zeo Crystal and become the Zeo Rangers. They face the Machine Empire with help from the Gold Ranger, whose powers are later entrusted to Jason before being returned to Trey.
