Pirantishead takes control of the Tyrannosaurus Dinozord and the Dragonzord, commanding them to destroy the city. Our heroes, Zordless, watch helplessly as their Zords go on a rampage. Zordon & Alpha unveil a new set of five Zords, enhanced by the power of Thunder.
Tommy, due to his lack of sustained energy, is not given a new Zord. Before they can create these new Thunderzords fully, they must regain their old ones. This is easier said than done, as Pirantishead has full control of them.
