Omni-Tricked Part 4. After his encounter with the villainous Vilgax, Ben is trapped cycling through aliens without hope of becoming human again. When Vilgax attempts to dangerously use a volcano to power his spaceflight home, Ben gets the idea to "upgrade" the Omnitrix to defeat his new nemesis and save the entire earth, which begs the question: what exactly was the Omnitrix upgraded to?!?

While on a seemingly endless summer vacation with his Grandpa Max and Cousin Gwen, Ben Tennyson discovers an alien watch: the Omnitrix. This device gives Ben the ability to transform into any one of ten spectacular and powerful aliens! Ben, Gwen and Max travel the country in their motor home affectionately known as the Rust Bucket seeing the sights, stumbling into adventures and beating down would-be villains while generally having a blast!
