Shadow King

The Shadow King (Amahl Farouk) is a supervillain appearing in American comic books published by Marvel Comics, primarily as an enemy of the X-Men. His nemesis is the X-Men's leader, Professor X, while he also figures into the backstory of the X-Man Storm. As originally introduced, Farouk was a human mutant from Egypt who used his vast telepathic abilities for evil, taking the alias Shadow King. Later writers established Farouk as the modern incarnation of an ancient evil entity. The Shadow King has appeared in various adaptations of X-Men stories. The character's live-action debut is as the primary antagonist in the television series Legion, portrayed by Aubrey Plaza and Navid Negahban.
