Caliban is a mutant that can sense other mutants within a 25 mile radius of himself. He was a Morlock, a member of X-Factor and X-Force as well as Apocalypse's faithful hellhound.
For a while Caliban was known as Hellhound, but was later officially announced as Death, Archangel's replacement in Apocalypse's Horsemen. He would use his enhanced senses and strength to locate more mutants for Apocalypse, and his personal anger and rage to punish his enemies. However, after Apolcaypse was defeated on the moon by the combined forces of X-Factor and the Inhumans, Caliban returned to Earth and began his hunt for Sabretooth, who had returned to the Morlock tunnels to kill any remaining Morlocks. As Sabretooth hunted the remaining Morlocks, Caliban hunted him. Caliban was unaware of Sabretooth's healing factor, so when he broke Sabretooth's back and left him for dead, he had unwittingly spared him his life.
