15The X-Men Connection
David Haller, aka Legion, is a well-established character in the Marvel comic universe. Created by legendary comic book men Chris Claremont and Bill Sienkiewicz in the 1980s, Legion has had a rough run in the comics world. Because of his mental illness, which he shares with the main
character of the show, he has vacillated back and forth between hero and villain, between ward and prisoner. The comic version of Haller is actually the son of Charles Xavier (Professor X) and has a long, storied history with the X-Men.
Showrunner Noah Hawley has, in interviews, not entirely ruled out the X-Men connection. It is clear from his comments that he’d like the show to stand on its own, but that it does take place within the X-Men movie universe (or maybe just the Logan universe). As of the first episode, there is no clear link between the show and the larger X-Men picture. There is also no direct indication that Haller is Xavier’s son, though nothing has been ruled out either.
