Powers; Madrox creates an identical physical living duplicate of himself upon any physical impact, possibly via extradimensional mass acquisition similar to the process used by Ant-Man or the Hulk. This process is spontaneous and cannot be prevented by Madrox. Although he can create multiple duplicates, and the duplicates themselves can also replicate, each is only able to create one duplicate at a time; he has been seen to produce around forty duplicates before no more would be created. The duplicates think, feel, and act independently, though usually guided by the original. Each tends to manifest one aspect of Madrox's personality, which increases in strength with lengthier separation from the original; these traits have recently become more extreme. Madrox is telepathically and empathically linked to his duplicates, suffering severe, potentially fatal, trauma if one dies. Madrox can "reabsorb" his duplicates, gaining their new knowledge and skills. Similarly, he will acquire any physical injury - though not any actual toxin - from a duplicate; symptoms are typically lessened by half during absorption. If Madrox himself were killed, it is not known whether any existing duplicates would continue to function independently; it is virtually impossible to distinguish the original from the duplicates.
Abilities; Madrox has acquired extensive knowledge and skills via his duplicates' experiences, such as human anatomy, speaking Russian, and Shaolin monk stealth techniques.
Weapons; None
Paraphernalia; Madrox's original costume absorbed kinetic energy, preventing accidental duplication. Madrox's strength was proportionately increased via this absorbed energy.
