Legion follows David Haller, a troubled young man who may be more than human. Diagnosed as schizophrenic, David has been in and out of psychiatric hospitals for years. But after a strange encounter with a fellow patient, he's confronted with the possibility that the voices he hears and visions might be real.
Legion is based on the Marvel Comics character created by Chris Claremont and Bill Sienkiewicz in the pages of the X-Men spinoff series New Mutants. Legion, real name David Haller, is the mutant son of Professor X. David is an incredibly powerful mutant with a full array of powers, but each of those powers is controlled by one of his multiple personalities, and not all of those personalities have David's or anyone else's best interests in mind.
Legion is created by Noah Hawley (Fargo), who will also serve as showrunner, and is a co-production of Marvel Television and FX Productions. Legion stars Dan Stevens as David Haller, along with Rachel Keller, Jean Smart, Aubrey Plaza, Jeremie Harris, Amber Midthunder, Katie Aselton, and Bill Irwin.
Legion premieres on Feb. 8, 2017, at 10 p.m. ET on FX.
