How Professor X Fits Into the Final Season of FX’s ‘Legion’

TCA 2019: Get ready to see how the ”X-Men“ leader defeated the Shadow King

For its final season, “Legion” is bringing in its most famous mutant this side of Wolverine: Charles Xavier, better known as Professor X, the leader of the “X-Men.”

But Xavier’s (who will be played by “Game of Thrones” alum Harry Lloyd) appearance on the FX drama will be one fraught with more personal stakes. He is David Haller’s (Dan Stevens) father, after all. Though the identity of Haller’s father was heavily teased as being Xavier (just like in the Marvel comic the series is based on), this will mark the first time it’s 100 percent confirmed.

“We know enough, even in the mythology of the show, to know that when David was born his father went off to fight [Amal Farouk] and kick Farouk out of his body,” Noah Hawley, the show’s creator, told TheWrap. “And so I think what we’re going to explore, is that story.”

And it will involve time travel, something the show already has experience with.

At the end of Season 1, David learns that he’s been mentally tormented his whole life by Amahl Farouk (Navid Negahban), also known as the Shadow King. After losing a telepathic battle with Xavier, Farouk attached himself to David as a parasite within his own mind when he was a child. In a cruel twist of irony, Xavier sent David away as a child in order to keep him safe from Farouk’s influence. Earlier in the season, a brief glimpse of Xavier’s wheelchair was also shown in a flashback.

“At a certain point, his parents felt like the child was in danger and so they gave him away to be raised by somebody else,” Hawley continued. “Not because they didn’t want him, but for his safety, without realizing that already that he had been compromised.”

Hawley said getting the famous “X-Men” leader into his show was always his intention, though he knew he was going to have to get through some corporate red tape first.  Twentieth Century Fox owns the rights to “X-Men” and still has one more film to get out before it’s acquired by Disney — June’s “Dark Phoenix” — which will see James McAvoy play Charles Xavier for the fourth time. Prior to McAvoy, an older version of Xavier was played by Patrick Stewart in the first batch of “X-Men” films.

“The movie studio definitely controls that story and those characters and there was a negotiation that had to go on,” Hawley explained. “Going into this third story, that conversation began to be had at the highest levels, because I can’t finish the story unless I can do it.” And Hawley said the studio basically let him do what he wanted with the character, instead of putting shackles on what he could and couldn’t do.

“The good thing with ‘Legion’ is that our reality is so detached from the comics — or anything — because it’s David’s subjective experience,” he said. “The tesseracts in his reality doesn’t really have to linearly tie to anything we’ve seen before.”

In the comics, David is the illegitimate son of Xavier and his lover Gabrielle. Gabrielle kept David’s existence a secret from his father for years, though Xavier eventually found out that he had a son, and yes, he had dangerous mutant powers and serious mental instability. How much the TV version adheres to the comics — which has always been very loose — remains to be seen. Hawley teased that even he doesn’t yet know if this will end up being a good thing for David.

“Whether David is going to get what he wants out of that or not it to be written.”

The third and final season of “Legion” premieres on FX in June.
