Megas XLR (2004)

Coop accidentally teleports himself directly into the Karrajor, the Glorft Mothership, and now Kiva and Jamie have to figure out how to pilot Megas to save him. They do okay at first, but eventually crash into the Glorft mothership and get themselves - and Megas - captured. Fortunately, Gorrath foolishly lets Coop get the car, so Coop tears through the ship, intent on rescuing his friends and Megas. Now Coop must rescue everyone while finishing off the Glorft invasion once and for all, but how is he supposed to do that when the sheer amount of Glorft mech's overpowers even Megas and tears off several vital parts? Even worse, the Glorft have a new mech, the Karrajor in Mech mode, which is even larger than the UMD, which raises the question: how will Coop defeat this new threat with a critically damaged Megas?
