The Ben 10 Story

Ben 10 premiered on Cartoon Network on December 27, 2005. The show is about Ben Tennyson, who finds a device called the Omnimatrix (Omnitrix), which allows him to transform into 10 different aliens, spending the summer with his cousin, Gwen Tennyson and his paternal grandfather, Max Tennyson. Ben 10 lasted for four seasons and was replaced by Ben 10: Alien Force, by 2008.

Ben 10: Alien Force premiered on April 18, 2008, which takes place five years after the first series. Not only is Ben five years older and matured, but his Omnitrix is recalibrated and contains entirely new aliens and Kevin, from Ben 10, had changed sides and is now part of the team. Ben 10: Alien Force lasted for three seasons. A preview was shown during the last episode of Alien Force, for the now active series, Ben 10: Ultimate Alien.

Ben 10: Ultimate Alien premiered on April 23, 2010. This follows a now 16-year old Ben and Gwen and 17-year old Kevin about a few weeks after Alien Force. Ben's secret identity has been revealed to the world by a kid named Jimmy Jones, and Ben is now an international super hero, loved by kids all over the world, but distrusted by most adults. Ben is armed with a more powerful new device called the Ultimatrix.
