Ben 10: Alien Force is an animated TV series created by the Man of Action team and produced by Cartoon Network Studios. It is a darker follow-up to the original Ben 10 series and takes place five years later. The show premiered in the US on April 18, 2008, and ended on March 26, 2010, after three seasons and forty-six episodes. It was nominated for four Emmy Awards, winning one for Outstanding Sound Mixing.

The show follows Ben Tennyson, now a teenager, as he once again dons the Omnitrix to protect the Earth and other parts of the universe from evil alien activity. The Omnitrix is a device in the shape of a wristwatch that allows Ben to transform into various alien forms and inherit their unique abilities. With the help of his cousin Gwen and his friend Kevin, Ben faces off against a variety of alien villains.

Throughout the series, the trio faces off against the Forever Knights, Xenocytes, DNAliens, and the Highbreed, among others. The show takes a more serious tone than its predecessor, with more complex storylines and character development. The final episode of the series aired on March 26, 2010, but a sequel titled Ben 10: Ultimate Alien was released afterward.
