Gambit - Remy LeBeau

Abandoned at birth due to his burning red eyes, the child who would one
day become Remy LeBeau was kidnapped from his hospital ward by members
of the New Orleans Thieves' Guild who referred to the child as "le
diable blanc" - the white devil. They believed he was the child that
had been prophesied to unite the warring Guilds. Soon after, Remy was
placed in the care of a gang of street thieves who raised the child and
taught him the ways of thievery.

Later, when he was around ten years old, Remy attempted to pick the
pocket of Jean-Luc LeBeau, then-patriarch of the Thieves’ Guild.
Jean-Luc took the boy in off the streets and adopted him into his own
family. As part of a peace pact between the Thieves’ Guild and their
rivals, the Assassin’s Guild, a marriage was arranged between Remy and
Bella Donna Boudreaux, the granddaughter of the head of the Assassin's
Guild. However, Bella Donna's brother Julien objected to the marriage
and challenged Gambit to a duel. Remy killed Julien in self-defense,
but was excommunicated and banished from New Orleans in an attempt to
maintain the nonaggression pact between the two guilds.

Remy
 wandered the world as he plied his skills as a master thief, aided by
his mutant power to charge objects with explosive energy. He employed
playing cards he charged with kinetic energy as his trademark weapon.
At one point Remy had approached the master geneticist Mr. Sinister for
help in controlling his powers. Sinister removed some of Remy's brain
tissue to reduce his power levels, thus affording him a greater degree
of control. As a result, Remy was now in the geneticist's debt, and
Sinister subsequently charged the thief with assembling the team of
assassins called the Marauders. Remy did not realize that Sinister would employ the Marauders to massacre the underground mutant community known as the Morlocks. Seeing the horrific results of his actions, Remy attempted to stop the massacre but was almost killed by the Marauder named Sabretooth. However, he did manage to save one young Morlock girl who would one day grow up to become the X-Man named Marrow.

Eventually, Remy encountered Storm, a member of the outlaw team of mutant adventurers known as the X-Men.
 Storm had been transformed into an amnesiac child who had turned to
theft as a means to survive. Remy helped her escape her enemy, the
malevolent psionic entity known as the Shadow King, and they became partners. Later, when the X-Men's founder Professor Charles Xavier
 returned from a long period of traveling in outer space, Storm
sponsored Remy's admission into the X-Men. Remy soon fell in love with
his fellow X-Man, Rogue, blessed and cursed with the ability to absorb
other mutants' thoughts and abilities through skin-on-skin contact. The
feeling was mutual, but the two soulmates were condemned never to touch.
 At one point, Rogue left the X-Men after she kissed Remy and absorbed a portion of his memories, learning of his role in the Morlock Massacre.

Remy was subsequently captured and brought before a mock trial held by Magneto,
 the mutant master of magnetism, then disguised as Erik the Red. He was
 summarily cast out of the X-Men and was abandoned in the frozen wastes
of Antarctica. Starving to death, Remy made his way back into Magneto's
 citadel where he came upon the psionic essence of a dead mutant named
Mary Purcell. The wraith-like Mary bonded with him, allowing him to
survive until he reached the Savage Land,
 a hidden jungle nestled in the icy wasteland. There, Remy struck a
deal with the enigmatic being known as the New Sun. In exchange for
passage back to America, Remy agreed to run errands for the New Sun.

Remy returned home and encountered the X-Men again when he attempted to steal the fabled Crimson Gem of Cyttorak
 for his new employer. He agreed to return to the team, mainly for his
self-respect and for his love for Rogue. However, Mary began to
threaten Remy and his friends if he didn't agree to stay with her
forever. When the X-Men finally found out about Mary, the wraith fled
with Remy to her old hometown, where she tried to force him to merge
with her and become a new type of hybrid lifeform. While Remy wrestled
with her, Rogue charged in with a containment unit, which ultimately
dispersed Mary.

During a trip back in time, Remy's powers were restored to their
maximum potential by Sinister and he was able to utilize them to return
to the present. Soon after his return, Remy served for a time as
patriarch of the Thieves' Guild in his father's stead, as well as
leading one of two teams of X-Men. Remy was also responsible for the
unification of the Thieves' and Assassins' Guilds into the Unified
Guild, of which he also served briefly as patriarch.

Meanwhile, the New Sun revealed his true nature after organizing
an assassination game for a cadre of super-powered mercenaries with Remy
 as the target. When Remy took the fight back to the New Sun, he was
shocked to learn that the New Sun was actually an alternate reality
version of himself. In his own reality, the New Sun's kinetic charging
powers had flared out of control, burning the world and killing
everyone. As a result, the New Sun hunted down and killed versions of
himself in other realities to ensure that they would not repeat his
mistakes. During their final battle, Remy burned out his enhanced
powers to defeat the New Sun, ending his threat and returning his powers
 to their normal level.

Remy was later framed by mutant businessman Sebastian Shaw for the death of the Australian crimelord named Viceroy. With the assistance of Rogue, her team of X-Treme X-Men, and former Triad member Red Lotus,
 Remy was able to clear his name. Soon after, Remy became embroiled in
the X-Treme X-Men's fight against an alien invasion of Earth. He was
captured and used as a power source for the invaders to open a portal
that would allow their full invasion fleet to pass through and complete
the conquest of Earth. The process was halted by the enigmatic villain
known as Vargas,
 who plunged his sword into Remy's chest. Remy survived, but found that
 he had lost his mutant abilities. As a result, he and the
also-powerless Rogue sought to live a normal life together and retired
from the X-Men.

However try as they might, a normal life was not for them to lead as
the pair soon became embroiled in the X-Treme X-Men's fight against the
mutant predator Elias Bogan. After Bogan was defeated, the X-Man named
Sage used her mutant ability to "jumpstart" Remy's mutant powers and he
rejoined the team.

In an alternate future over 70 years from now in which the X-Man Bishop was born, Remy had become an aged figure named the Witness,
 so-called because he had apparently witnessed the betrayal of the X-Men
 by one of their own members. He was also thought to be the last
survivor of the X-Men. Upon joining the X-Men himself, Bishop suspected
 Remy to be the traitor until realized that Xavier's mind and Magneto's
mind spawned the corrupt psionic entity known as Onslaught.

During Apocalypse's
 most recent bid for power, Gambit joined Apocalypse's side as the
horseman, Death. Gambit believed that Apocalypse would be able to save
the mutants, but he would be able to stop Apocalypse should he betray
them.

As Death, Gambit attacked his lover Rogue and his former group
X-Men. Cyclops arrived with The Avengers to stop Apocalypse and his
Horsemen. Apocalypse finally lost, and seems dead for a while. Sunfire,
Apocaypse's other Horseman rescued Death from battle and they escaped.
Afterwards they returned to take Polaris, who had also become a Horseman
 of Apocalypse only to find Polaris had been injured in the last battle
and was now in a coma. Death and Sunfire lost the battle and were forced
 to run from the X-Base. Afterwards they discussed what will happen to
them without Apocalypse. During their conversation, Mr. Sinister found
them and they joined his Marauders.

As Death, Gambit regretted attacking Rogue. Sinister rescued him
from his Death form, leaving Gambit feeling betrayed by the X-Men and
indebted to Sinister. In the end, Gambit decided to stay with Sinister.
 The Marauders waited for the right time to attack the X-Men, with
Gambit at the Marauders' side. During the battle, Mystique betrayed the
X-Men and shot her step-daughter Rogue, Gambit's lover. They then took
Rogue and ran. The Marauders had won the first battle.

After that, Gambit and Sunfire attacked Cable. Cable lost and was
 thought to be killed by Gambit, but Cable was in fact not dead.

The X-Men went to the Marauders for the baby where Wolverine
injured Gambit, and learned the baby Messiah was actually with Cable.
Upon learning the Marauders had no idea where the baby was, it was
surmised Gambit assisted Cable in taking her.

When Bishop attacked Cable, Gambit rescued the baby, but as he
returned to Sinister, he discovered Mystique killed him. Gambit felt as
if he was finally free, and when Mystique used the baby to try to heal
Rogue, Gambit saved baby again. Professor X and Cable came to take
child, so Gambit gave the baby to them. Rogue was healed, and even
though she wanted to kill Mystique, she didn't. Rogue's final request of
 Gambit was that he didn't follow her.

The Acolytes kidnapped Xavier's body, and Exodus healed him to lead
them, but Xavier declined the offer. Xavier, with the help of Eric
Magnus Lehnsherr, defeated Exodus at the cost of losing his memories
after Bishop shot him. When Xavier's life was again threatened, Gambit
had followed and saved him. Charles, didn't remember Remy, but he used
his telepathic powers on Remy and saw many images locked inside his
mind. Soon another group of attackers assaulted the duo, and Sebastian
Shaw came to their rescue. Somehow, something done to Xavier in his past
 by Mr. Sinister caused Xavier to take on his personality and abilities.
 A Doctor Mueller tried to take Sinister's power from Charles, and even
with Gambit and Shaw's help, it was unsuccessful. Gambit found Professor
 X's body, but it's not Xaiver anymore - the Professor changed to
Nathaniel Essex (Mr Sinister).
