What Happened To Everyone Who Became Horsemen Of Apocalypse?

14. Caliban

Caliban was another mutant to join Apocalypse in the aftermath of the Mutant Massacre, although one not nearly as notorious as the previously mentioned Archangel.

Like Warren, Caliban was serving with X-Factor by the time Apocalypse came around. When he saw what he did to Angel, he begged Apocalypse for equal treatment, determined to seek revenge against those who had wronged the Morlocks during the earlier massacre. From there he became a hellhound, but after Archangel broke Apocalypse's control he then also assumed the title of Death.

For a while, though, Caliban is able to shake Apocalypse's control. He joins up with X-Force, but is then plucked away by En Sabah Nur once more, where he is then bestowed the title of Pestilence. This time around, Apocalypse alters his powers even further, granting him the ability to spread disease telepathically. (No, we don't know how it works either, just role with it.)

Caliban actually gets released by Apocalypse in the end, and goes on to live the rest of his life helping the X-Men, passing away during the events of Messiah Complex.
