History
Arclight shared a similar history to her Earth-616 counterpart up until Archangel became the Horseman of Death and managed to "rebel" against his master. After several mutants showed up dead, X-Factor attempted to capture all known rogue mutants for their protection/determine if they were the killer. The Marauders met to discuss what there future plans should be with Arclight being present. [1]
