History
Mystique shared a similar history to his Earth-616 counterpart up until Archangel became the Horseman of Death and managed to "rebel" against his master. After several mutants showed up dead, Mystique was contacted X-Factor to inform them Freedom Force was to be put under their protection/rule them out as suspects. Mystique refused so X-Factor attacked to knock them out and detain them.[1]
