Dinobot's sudden change in allegiance causes Rattrap to distrust him even more. When Megatron and Rampage discover that a valley with early anthropoid humans exists he decides to destroy the valley and everything that was in it to prevent the human race from existing long enough to interfere with the wars between the Autobots and Decepticons. Dinobot realizes that Megatron's powers will be limitless if he doesn't stop him from destroying the valley. Dinobot then radios Optimus for help but finds that he must make things right.
