In an effort to regain control of the Dinozords, Billy & Trini create a Signal Blocking device. It works perfecty (after installing the batteries correctly), and Pirantishead loses control of the Tyrannosaurus & Dragonzord.
Zordon then infuses each of the main five Dinozords with a lightning charge, causing them to morph into the mighty new Thunderzords! The Red Dragon, the Yellow Griffin, the Blue Unicorn, the Black Lion, and the Pink Phoenix come together to form the Thunder Megazord. With it, Pirantishead is sliced in half by their Saber.
Lord Zedd is furious upon failing, blaming Baboo, Squatt, and even Goldar for the loss. Our heroes quickly turn to the chairty 4-wheeler race, just in time to finish near-last. Oh, and Bulk & Skull, saved by the Rangers for the umpteenth time, decide on a new mission in life: to find the secret identities of the Power Rangers!
