Caliban

Caliban (voiced by Michael Dobson) is a mutant in the X-Men series. Caliban was named by his father after the grotesque creature in Shakespeare's play, The Tempest. A mutant with the mental power to sense and detect other mutants nearby, Caliban helped Callisto assemble the underground society of mutant outcasts called the Morlocks. Before Caliban joined X-Force, Apocalypse vastly increased his size and strength and gave him the role of Death, one of Apocalypse's Four Horsemen. Caliban can psionically intensifies other's fears and can create a psychoactive virus that attacks the mind.
