When does The X's return?

The X's is an American animated television series created by Carlos Ramos for Nickelodeon. The series centers on a nuclear family of four highly trained spies who must conceal their identity from the outside world. Mr. X (voiced by Patrick Warburger) is the team leader of the X's, and the main protagonist of the series. Jim Smith, alumni of The Ren & Stimpy Show, was a prominent storyboard artist on the series; he alongside Vincent Waller were instrumental in the formation of Nickelodean Animation Studio, having refused to join the studio after Spümcø was terminated from the series. The series premiered in multiple countries throughout Latin America in 2006.
