Legion, based on the Marvel comic book of the same name, sees Dan Stevens as David Haller, a man who believed himself to be a schizophrenic, only to uncover the truth that he may actually be the most powerful mutant in the world.
The character of Switch also exists in Marvel comic continuity, where she is portrayed as Devon Alomar, a member of the Hellions who is able to possess the bodies of others by switching minds with them.
Season three of Legion is slated to air later this year, and features a cast that also includes Rachel Keller, Jean Smart, Jeremie Harris, Amber Midthunder, Bill Irwin, Aubrey Plaza, Jemaine Clement, Hamish Linklater, and Navid Negahban.
