Ben 10: Alien Force begins the next chapter in the continuing Ben 10 saga five years later when 15-year-old Ben Tennyson chooses to once again put on the OMNITRIX and discovers that it has reconfigured his DNA and can now transform him into 10 brand new aliens. Joined by his super-powered cousin Gwen Tennyson and his equally powerful former enemy Kevin Levin, Ben is on a mission to find his missing Grandpa Max. In order to save his Grandpa, Ben must defeat the evil DNALIENS, a powerful alien race intent on destroying the galaxy, starting with planet Earth. Ben will join forces with other young heroes to save the galaxy and his Grandpa Max, while passing along his knowledge to a whole new generation. The animated series will premiere with a special one-hour episode on Cartoon Network in Spring 2008.
