Ben 10 Alien Force

---Plot of Ben 10 Planet---
Ben 10: Alien Force (formerly called Ben 10: Hero Generation) is the sequel series to the original Ben 10 series. 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 (formerly called Ben 10: Evolution).
Alien Force is set roughly 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. This change received mixed reactions from the fans, and caused a division amongst them. Despite this, Alien Force's ratings were successful, allowing the production of Ultimate Alien. In this serie,Ben meets a girl,called Julie and she become the "first" girlfriend of our hero.
