Lord Zedd had come to the Moon, to try destroying the Power Rangers and taking over Earth himself. He sent down Pirantishead, who succeeded in freezing four Dinozords and taking control of the other. A simple refractoring of morph waves by Alpha 5, the Dinozords became Thunderzords, much more powerful than there predecessors.The Thunder Zord squadron battled the forces of Lord Zedd with their massive power, far better then the Dino Zords. The Thunderzords were Red Dragon, Lion, Griffin, Unicorn, and Firebird. They combined to form the Thunderzord assault team, with the Red Dragon riding the other four combined as an airborne chariot, and the Thunder Megazord. The Thunder Zords fought numerous battles until they were destroyed by Rito Revolto.
