The Mutiny, Part III

Summary
Tyrannosaurus and Dragonzord begin to attack the bystanders of the bike event. Billy and Trini complete the device to stop Pirantishead's signal.

When it doesn't work at first, the five main Rangers use the Power Blaster to injure Pirantishead so Green Ranger can troubleshoot the machine. Blue Ranger realizes that a battery was in the wrong position, and the device finally works. The zords are freed.

Lord Zedd uses his magic to sink the zords below the Earth's surface. Dragonzord is sent to slumber in the ocean before Zedd can do the same to it. Alpha is able to recover enough of the old zords to create the Thunderzords. Zedd has turned Pirantishead into a giant. The Thunderzords are called for and form Thunder Megazord. It finishes off Pirantishead with the Thunder Saber. Tommy watches the battle from the Command Center, and Alpha says that they'll find a way to fully recharge his powers.

Lord Zedd is furious over his first loss and blames his underlings. Finster mutters that it wouldn't have happened if they had used one of his monsters.

On the viewing globe, the Rangers see what happened to Rita. She's stuck in her space dumpster, floating in space. Bulk and Skull are stuck on their bikes, which are still under the influence of Pirantishead's magic. The gang uses the device to help them. Everyone rides their bikes across the finish line of the race.

Errors

 * The zords are very big. So why didn't the bystanders notice these huge robots before riding their bikes into their direction?  Dragonzord's missiles and Tyrannosaurus' breath attack would have surely killed these people, but all it did was blow up some ground.


 * Zordon mistakenly calls the Thunder Megazord (its official title) the "Mega Thunderzord". This happens several times this season.
