Jamie has the ability to make duplicates of himself called Kinetic Duplication.
In the town of Los Alamos, New Mexico, it was immediately apparent that Jamie Madrox was a mutant as soon as he was born. When the doctor performed the old-fashioned smack to encourage the baby to cry and breath, a twin baby suddenly appeared. However, it wasn't a twin, but a duplicate. James Arthur Madrox was a rarity amongst mutants, in that his mutation was clear from birth, instead of waiting to develop in his teenage years. He would uncontrollably form a duplicate of himself upon physical impact. This was a shocking experience to the doctor and to his parents as well.
Professor X was an old friend of the Madrox family and upon his advise Jamie's family moved to a farm in the middle of Kansas. Jamie's father, Dr Daniel Madrox created a special suit for Jamie to wear that would inhibit his mutant power.
