Ben 10: Alien Force

Ben 10: Alien Force is the sequel to Ben 10. It was created by the studio Man of Action and produced by Cartoon Network Studios. This series is followed-up by another sequel series called Ben 10: Ultimate Alien.

Alien Force is set five years after the original series. The storyline is notable for having matured the character and taking a darker tone, with more complex plots and more characters dying.

Plot
Five years after the events of the original series, 15-year old Ben Tennyson has returned to a normal, everyday life. His adventures all done, Ben has taken off the Omnitrix and has grown from a young boy into a confident teenager. However, the mysterious disappearance of Grandpa Max forces Ben to wear the Omnitrix again, as well as forcing him, his cousin Gwen, and his old enemy Kevin to search and locate Grandpa Max. At the same time, they must enlist the help of the Plumbers' kids (children or grandchildren of retired Plumbers which are commonly half human and half alien) and repel attacks from a new enemy, the Highbreed.

In the third and final season, Vilgax returns as the main antagonist forcing Ben, Gwen, and Kevin to tackle bigger problems and find out more secrets about the Omnitrix. In the series finale, The Final Battle, Ben faces Vilgax again in their final battle, destroying the Omnitrix in the process. At the end, Ben is now armed with a new Omnitrix called the Ultimatrix.
