Prince Gasket and Archerina have created the Chronosapios, a crystal ball-like device which alters the space-time continuum, causing it to repeat, but so far only Tommy has been affected. When the Rangers discover the plot and go to destroy the device, Prince Gasket sends the Protectron monster to guard the crystal ball. The Rangers manage to destroy the Chronosapios, but when the Protectron grows to huge proportions they must first call on the Super Zeo Zords, and then the Warrior Wheel, to destroy it and set time back to normal.
