Powers and abilities
Madrox's duplicates can die without long term physical harm to himself, as demonstrated when the mutant Proteus possessed a duplicate then consumed its life force — leaving only a burnt out husk, as with all victims of Proteus. The possession caused Madrox to collapse in pain, aware of what was happening, but he later recovered. Another Madrox dupe died of the Legacy Virus, but Madrox himself was unaffected, although he would presumably have received the virus if he absorbed the infected dupe.
