aka James Arthur "Jamie" Madrox, is a fictional character, a Marvel Comics superhero, associated with the X-Men.
Created by writer Len Wein with script from Chris Claremont and art by John Buscema, he first appeared in Giant-Size Fantastic Four #4.
Jamie Madrox was born to a family living near the Los Alamos research facility in New Mexico; the background radiation may have stimulated his mutation.
When Jamie was born, the doctor's slap causes him to multiply into two identical babies. Professor Charles Xavier, a friend of the Madrox family, suggests that they move to Kansas to raise the boy in privacy.
Dr. Daniel Madrox, Jamie's father, creates a suit for him to wear which is designed to absorb kinetic energy, the source of the duplication.
Later, Damian Tryp, of Singularity Investigations, makes his own offer to look after Jamie, claiming that Jamie is not just a normal mutant, but actually a "changeling", a predecessor to mutants who develops its powers at birth.
Jamie's parents refuse to give Jamie to Tryp. When Jamie is fifteen years old, his parents are killed by a tornado alleged to have been caused by Tryp, and Jamie begins to run the farm by himself along with his duplicates, or "dupes", until his suit is damaged.
Madrox goes to New York City for help where he meets Mister Fantastic of the Fantastic Four. He contacts Professor Xavier, who sends the youth to Muir Island with Moira McTaggert, to work in her laboratory and help her with research.
He later helps Moira and fellow mutants Havok and Polaris in searching for the escaped mutant, Proteus. Proteus hijacks one of Madrox's duplicates as his own body, although this does not harm Madrox.
Following the X-Men's battle with Proteus on Muir Island, Madrox was invited to join the X-Men, but he declined.
(Luornu Durgo) is a fictional character, a superhero in the 30th and 31st centuries of the DC Comics Universe and a member of the Legion of Super-Heroes.
She has also used the aliases Triplicate Girl, Triad, Una and Duplicate Damsel.
She first appeared in Action Comics #276 and was created by Jerry Siegel & Jim Mooney.
A native of the planet Cargg, Luornu could split into three identical bodies, as could all Carggites, due to the planet Cargg having three suns.
Her costume consisted of a purple dress, orange cape and belt, and black boots.
She was the fourth hero to join the Legion of Super-Heroes, and its first non-founder member.
Unlike her post-Zero Hour counterpart, Triad, she had brown eyes, not split purple/orange ones.
For a long time, she had an unrequited crush on Superboy.
One of her three bodies was killed by Brainiac 5's killer creation Computo The Conqueror (a rogue computer) early on, and she was thereafter known as Duo Damsel.
Her surviving two bodies continued to remember the trauma of experiencing her/their death, with the result that Computo was the one villain whom Duo Damsel was too frightened to confront.
Duo Damsel later donned a unique half orange, half purple costume which could divide with her, leaving one body wearing an orange costume and one wearing a purple costume.
The costume was initially designed to aid her in a mission on the planet Pasnic, but the character continued to wear "splitting" costumes such as this throughout most of the original continuity.
Duo Damsel left active Legion service to become a reservist after marrying fellow Legionnaire Bouncing Boy in Superboy #200; after this she then appeared only sporadically.
In later years of the first Legion continuity she served as an instructor at the Legion Academy along with her husband.
She suffered the death of one of her two remaining bodies battling the Time Trapper after she took part in a conspiracy to avenge the death of Superboy, which had been caused by the Trapper (After a minor reboot in 1990, it was stated that Glorith killed the second body during a conspiracy to avenge her genocidal destruction of the Daxamite race).
It was revealed that Luornu's second body was still alive.
This body, and the ability to duplicate herself, were restored to her, and she gained a new ability to generate force fields. This new ability was transferred to her by a special force field belt given to her by Brainiac 5 to protect her after the supposed death of her second body.
