Description: The Earth is the battleground in an age-old struggle for control over the universe. Ordinary looking planes, cars, and vehicles suddenly transform into mighty robots that wage war with the advanced armory of super technology. It's the Decepticons against the Autobots in a battle for the world's energy supply. With the help of human allies, the Autobots just might be able to keep control away from the power-hungry Decepticons. Featuring episode, "Rebirth 1-3," The Decepticons attack Autobot City in an attempt to steal the key to the plasma chamber on Cybertron. They succeed and Punch is badly damaged. The Decepticons (led by Cyclonus), ten Autobots (led by Hot Rod), and the key end up on the planet Nebulos.
Note that these 3 episodes make up the entire run of Season 4, as broadcast in the United States.
