The game was based on the episode Dr. Animo and the Mutant Ray, in which Ben broke the face plate of the Omnitrix, and when he transformed, he turned into hybrids of two aliens. The three alien hybrids from this episode are: * Stink Arms (Stinkfly and Four Arms) * Diamond Matter (Diamondhead and Grey Matter) * Heat Jaws (Heatblast and Ripjaws)
