The war between the good & heroic Autobots and the evil & villainous Decepticons continues as they flea their dying world of Cybertron to a new planet called Earth. The Autobots, not wanting Earth to end up like Cybertron did, strive to protect Earth with the help of Spike Witwicky, his wife Carly, his son Daniel, his best friend Chip Chase, and the military organization known as NEST (Non-biological Extraterrestrial Species Treaty). The Decepticons plan to rule the planet by killing the human race.
