Synopsis
The Ranger teens take part in a charity 4-wheeler race on Earth. But up on the moon, things are far from routine. Rita Repulsa and her gang plan yet another attack, when Lord Zedd, Rita's boss and evil overlord, returns to our galaxy!
The tall, skin-less, metal-plated face, tubed-veined man arrives, and has Rita placed in another Space Dumpster. She's failed once too often for his tastes, and she has to go. Goldar quickly changes allegances, helping to shrink Rita down and shoot her off into the depths of space forever. Zedd alters most of the castle, and changes the Putty Patrollers into white-suited armored Z-Putties. They're sent down to Earth, and prove formidable foes, until their weaknesses are discovered (hit the big Z power source on their chests, and they shatter to pieces).
Zedd creates the Pirantishead monster from a fish out of the Rampoon River, and sends it to Angel Grove. Its twin-fish flutes cause all of the Dinozords to become instantly frozen!
