Caliban is an albino mutant character with the ability to track other mutants. He first appeared in Uncanny X-Men #148 in 1981. He was introduced as a meek member of a community of mutants that lived underground and avoided conflict with the outside world, The Morlocks. He later would ally himself with Apocalypse in exchange for a more powerful form. A minor character in the X-Men universe, he has switched sides several times depending on the story. The character appeared in the service of Apocalypse in X-Men: Apocalypse played by Tomas Lemarquis.
Last week, two major roles for the film were revealed (see “Two Key 'Logan' Roles Revealed”).
The film is due in theaters on March 3, 2017.
