In Marvel Comics canon, Danielle Moonstar (aka Mirage/Psyche) is a Cheyenne mutant who can create illusions based on her opponents' greatest fears and wishes. One of the leaders of the group of teenagers, she plays a central role in the influential 1984 storyine "The Demon Bear Saga," which is thought to be a significant influence on the film.

The New Mutants is described by Boone (The Fault In Our Stars) as “a full-fledged horror movie set within the X-Men universe,” one without costumes or supervillains. A plot synopsis suggests the film will deviate significantly from the source material: “Held in a secret facility against their will, five new mutants have to battle the dangers of their powers, as well as the sins of their past. They aren’t out to save the world — they’re just trying to save themselves.”

The New Mutants arrives in theaters April 13, 2018.
