Ben 10: Alien Force is an American animated television series created by Dwayne McDuffie and Glen Murakami and the studio "Man of Action" (a group consisting of Duncan Rouleau, Joe Casey, Joe Kelly, and Steven T. Seagle), and produced by Cartoon Network Studios. It is a sequel to Ben 10.
Set five years after the original series, the storyline is notable for having matured the characters and taking a darker tone, with more complex plots, and sometimes characters dying on-screen.
