Place of Birth


First appearance



Jamie Madrox's mutant ability was apparent at birth when a duplicate was created upon his being slapped by the doctor. Two weeks later, Jamie's father resigned from the Los Alamos Nuclear Research Center and moved his family to an intentionally isolated farm in Lawrenceville, Kansas at the suggestion of Professor Charles Xavier. Later, Damien Tryp, of Singularity Investigations, made his own offer to look after Jamie, claiming that Jamie was not in fact a mutant, but a "changeling," a predecessor to mutants whom develop their powers at birth. Jamie's parents, however, refused to give Jamie to Tryp. From a young age, Madrox was given a special suit to wear that would neutralize his mutant power, but before this could be explained to him a freak tornado killed his parents when he was 15, later revealed to have been caused by Tryp.

Madrox spent the next six years alone caring for his parents' farm. When he was 21, malfunctioning control elements in the suit caused a power surge that released his inhibited power and caused the suit to begin absorbing ambient electrical energy. Confused, frightened, and driven mad by isolation, Madrox felt himself drawn to New York City. There, he was found by Magneto who taught him to control and embrace his powers.

Powers and Abilities


Madrox is a Changeling, the genetic predecessors of mutants whose powers manifest at birth instead of during puberty. Madrox's powers include:

  • Kinetic Duplication: Jamie Madrox creates an identical physical living duplicate of himself upon any physical impact, possibly via extra-dimensional 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' personality, which increases in strength with lengthier separation from the original; these traits have recently become more extreme. Madrox is telepathically and empathetically linked to his duplicates, suffering severe, potentially fatal, trauma if one dies. If Madrox himself were killed, it is not known whether any existing duplicates would continue to function independently; it is said in theory, that if the original Madrox was killed, that one of his active dupes is capable of taking over as the new original and will assume the dominant abilities and collective personality that the original Madrox had. It is virtually impossible to distinguish the original from the duplicates. His powers have increased during his life. He was once able to create hundreds of dupes by himself. He has even gained better control of his powers, he has learned to prevent his body from producing duplicates, and has even been shown at one time to have duplicated without kinetic impact. Madrox was able to merge himself into the home-dimension of the duplicates, and came back without kinetic impact from the dupe who absorbed him.
    • Duplication Absorption: The original Madrox can absorb them back into himself at will, at the same time absorbing the memories, skills and experiences of the duplicate. The only limit to this power is he can't absorb a dead dupe.
    • Duplication Experience Transference: When Madrox merges back, he retains memories (albeit somewhat imperfect), knowledge, and experiences of the dupe. Madrox doesn't have to absorb his duplicates to absorb information from them, he automatically absorbs information from any of his dupes if it kills itself.
    • Duplication Healing: He also uses merging as a form of healing - Originally, uninjured Madri "shared" the damage when they reemerged (e.g., if an injured dupe merged with an uninjured Madrox, the resulting Madrox had an injury half as severe as the original injury). Now, however, the core Madrox can reabsorb injured or even near-dead dupes without taking on any of their physical injuries at all.


  • Madrox has acquired extensive knowledge and skills via his duplicates' experiences, such as human anatomy, speaking Russian, and Shaolin monk stealth techniques. He also has hand to hand combat training. Madrox has medical training and training as a gymnast, and can pick locks.

Strength level

  • Jamie Madrox possesses the normal human strength of a man of his age, height, and build who engages in intensive regular exercise.


None known.



  • Madrox once wore a suit that damped kinetic impacts so that he wouldn't duplicate from accidental impacts.

Transportation: None known.
Weapons: None known.


  • No special notes.


  • The plural form of Madrox has been given as both "Madri" and "Madroxes".
