Coop has found the ultimate robot and decided to revitalize it (it's been in a dump for the past 70 years)soon he gets a visit from a future girl named Kiva followed by the evil aliens which had conquered earth in the future. Now coop along with his best friend Jamie and the new future girl drive off an army of the Glorft, but this is only there first encounter!
Coop enters Megas in a local car show, and tries to show up fellow gearhead Tiny. Unfortunately, damage recieved in an earlier incident with a cheez whiz monster combined with Coop's showing off causes Megas to break down. The Glorft catch wind of this, and attack the car show in their efforts to capture Megas. With Megas crippled, Coop must rely on his new ""manual mode"" and the help of his gearhead friends to hold off the Glorft long enough for Kiva to get Megas running at 100%.
