FX's Marvel Comics adaptation "Legion" will come to a close at the end of its upcoming third season, the head of the network said.

John Landgraf, chief executive officer of FX Networks and FX Productions, said Monday during the Television Critics Association winter press tour that "Legion" would be ending after three seasons in accordance with the wishes of series creator Noah Hawley.

Landgraf said Hawley had always envisioned the show as a three-season story arc and the upcoming final season will allow the show to come to a natural conclusion.

"Legion," which stars Dan Stevens as mutant David Haller, was renewed for a third season in June. The premiere date has not yet been announced.

The series, based on the Marvel Comics by Chris Claremont and Bill Sienkiewicz, follows Haller as he discovers his schizophrenia might be a manifestation of powerful mutant abilities.

"Legion" also stars Rachel Keller, Aubrey Plaza, Bill Irwin, Amber Midthunder, Jeremie Harris, Jean Smart, Jemaine Clement, Katie Aselton, Navid Negahban and Hamish Linklater.

Hawley serves as executive producer alongside John Cameron, Lauren Shuler Donner, Simon Kinberg and Jeph Loeb.
