The news that someone at Fox may be stonewalling Legion from bringing on Professor X is disappointing, as so much of the show’s current story is rooted in the character.
Even bringing on Patrick Stewart to just show that one scene would be fantastic, although no one would complain if Stewart stuck around to play Xavier beyond that.
Legion has already confirmed the Shadow King’s origin story matched up with that of the comics, and that the villain’s consciousness was expelled from his body by Xavier and abandoned on the astral plane.
Beyond the fact that Charles Xavier is the father of David Haller, he’s also semi-responsible for why the series’ villain, The Shadow King, is causing so many problems.
