After Xavier: The Age of Apocalypse
Factor X consists of the Elite Mutant Force, who serve Apocalypse. They are split into five sibling groups: Cyclos and Havok (Scott and Alex Summers), Emplate and the M twins (Marius and Nicole & Claudette St. Croix), Cannonball and Amazon (Sam and Elizabeth Guthrie), the Bedlam Brothers (Jesee and Terrence Aaronson), and Aurora and Northstar (Jean-Marie and Jean-Paul Beaubier). The EMF is tasked with maintaining control of Apocalypse's breeding pens, where people are imprisoned, tortured, and experimented on by the dark Beast, also a member of the EMF.
This series shows the stories arround the hierarchy of Apocalypse´s most skillful mutants and the atrocities inside Apocalypse´s citadel.
