Play free Generator Rex games online and experience the thrill of being Rex, a teenager who can change his body into weird and wonderful machines. Now that’s cool! In ‘Enemy Alliance’, Rex must use his new weapons like the Funchuks and Blastcaster in a beat-em-up that pits our hero and Van Kleiss against an army of rock creatures created by the evil computer ZAG-RS. ‘Providence Defender’ is a superfast shooter sure to get your pulse racing. Rex uses his Boogie Pack to find humans, while Bobo blasts the flying EVOs. Perhaps the most challenging of the Generator Rex games, ‘Nanite Master’ sees Rex battle with the ferocious Biowulf.
