Xavier: Renegade Angel is an American adult animated black comedy television series created by Vernon Chatman and John Lee for Cartoon Network's nighttime programming block Adult Swim. It was produced by PFFR Productions, producers of Wonder Showzen, with computer animation provided by Cinematico. It premiered on November 1, 2007, on the Adult Swim website and November 4, 2007, on Adult Swim. Xavier features an elaborate and nonlinear plot following the musings of an itinerant humanoid pseudo-shaman named Xavier. The show is known for its use of ideologically critical dark comedy as well as surrealist and absurdist humor presented through a psychedelic and satirically New Age lens. The program is also normally rated TV MA for intense, graphic, often bloody violence, as well as strong sexual content, use of racially/ethnically offensive language, and grotesque depictions in a comedic manner.
