Age of Apocalypse
Remy was a close friend of Magneto's and a member of his resistance, but he fell in love with Magneto's ward, Rogue, who clearly reciprocated these feelings. Magneto promised him that he would find a way for Remy to touch her, but betrayed him by marrying her himself.
Remy was furious and broke all ties with Magneto and his team, forming his own group of rebels called the X-Ternals, which consisted of the mutants Lila Cheney, Jubilee, Sunspot and Strong Guy. He also started a relationship with Lila Cheney which, while not loveless, was always haunted by his former affair with Rogue.
However when Bishop was rescued, and the key to fixing the timeline was discovered, Magneto was quick to call on Remy for an almost impossible mission. He had to travel to the Shi'ar Imperium to retrieve a shard of the M'Kraan Crystal through which they could travel back in time. Ironically Magneto knew that he could trust Remy not to fail because he would not disappoint Rogue.
After the sacrifice of the truest part of himself (his love for Rogue), among other things, Remy managed to obtain the M'Kraan Crystal, but lost it through Strong Guy's betrayal, where he was forced to choose between the Crystal and Lila. Having no other option, and loving her more than ever, he chose Lila.
Magneto’s team retrieved the M'Kraan Crystal and they were successful, restoring the timeline to the way it should be. The rebels were then seemingly wiped out in a last-ditch, nuclear bomb attack on Apocalypse's domain in America by the humans.
However in the second Age of Apocalypse series it was revealed that Jean had saved them all and Remy went on working with Magneto, now to round up all of the mutants who had been followers of Apocalypse. While battling Sinister and his soldiers Remy was absorbed by Cloak and never seen alive again. The X-Men later buried their dead and created a tombstone for Remy saying, "Luck will always be on his side."
Gambit in Mutant X
Remy became a vampire in this reality, bitten by Bloodstorm to save his life. It happened on a mission to obtain two children, one of whom Remy would adopt and the other who would become X-Man, for Sinister from Apocalypse's laboratory. As Remy and Bloodstorm were partners in crime as well as lovers, she accompanied him and helped him infiltrate the building. Unfortunately, they were not stealthy enough as the Fallen detected them and attacked them. Remy was critically injured and begged Bloodstorm to change him into a vampire in order to save him, despite her reticence.
Despite this he managed to live some semblance of a normal life and his marriage to Belladonna cemented the alliance between the Thieves and the Assassins Guilds. Under his leadership, New Orleans became a safe zone for both humans and mutants, separate from any other politics.
However Julien still betrayed him in this reality, this time to Bastion, and this resulted in the death of Belladonna and the kidnapping of his adopted daughter. He chose to join Bloodstorm and the Six in order to get revenge, as well as rescue his child. He later abandoned them, once he had rescued Raven, as he knew that there was little hope of them surviving their latest encounter with Dracula.
Wraith
Todd Gambit was known as Wraith in the Amalgam reality. He obtained a magical set of playing cards in a New Orleans bar that allowed him to focus his mutant ability and change into a shadowy form. He joined Mr X's JLX, which was formed from the ranks of the Judgement League Avengers, and helped him find Atlantis, a long-lost mutant haven.
His powers also allowed him to touch Runaway, Rogue's Amalgam counterpart. However, because she absorbed some of his darkness each time they touched, she was gradually being driven insane and becoming reckless and evil.
New Son
New Son was born in the alternate reality's foremost mutant research and genetic planning facility, where he was trained for the use and exploitation of his mutant powers. When he hit adolescence he was finally skilled and powerful enough to incinerate the facility and escape, where he then made his way to the X-Men and found a home and family for a few years, until he killed that reality's Phoenix.
He was banished from the team and then spent some years both as an ally and foe of various superhumans and teams. When he was 18 he was taken in by Jean-Luc LeBeau, whom he eventually called friend and mentor, and while with the Guilds he was informed of the prophecies of the Resurrection of the Old Kingdom and his role in them. He was supposed to bring about heaven on earth and lead everyone as one into the shining light of the sun.
In a most tragic sense he did, but instead of the utopia for which the Guilds had hoped, the energies of the Old Kingdom, when combined with his biokinetic powers, created an uncontrollable cascade of energy that destroyed everyone and everything save New Son. Driven mad by guilt and grief he tried to undo his actions by controlling time through manipulating the flow of kinetic energies, but he could only breach the space between multiverses. So, now able to travel between realities, he decided to prevent his alternate counterparts from making the same tragic mistake as he had.
His original plan for Remy’s Earth had been to create an alternate earth in orbit around the sun, to which end he had Remy appropriating the technology he needed, however the fake world that Doom had shifted back from the universe to which the Fantastic Four and the Avengers had gone made that impossible. The orbital paths were too precise, and enough tension already put on them, to make another earth feasible. Instead he decided to try and get Remy to understand and control his powers through the Assassination Game and as that had failed he attempted to kill him.
Remy however managed to successfully defeat New Son and as a result of their battle, and the fact that Remy had supercharged him, New Son exploded when he was impaled on the spear of the King of the Old Kingdom.
X.S.E Future
In the the timeline that Bishop comes from the elderly Witness, said to have been the last person to have seen the X-men before they were killed, was also known as LeBeau. Shortly after having come to the present Bishop began to believe that Remy was the Witness, although a younger version of the man, and this lead to distrust and allegations that Remy was the traitor who betrayed the X-Men to their graves.
However the Witness also made an appearance in the present, with both Remy and Bishop present, and he revealed that he existed simultaneously in all timelines at once, this being the reasoning for him witnessing and knowing everything.
Who the Witness really is is a question that still hasn't been answered, although there is speculaion that Remy’s powers will evolve or be altered to allow him to become the Witness or that the Witness is Remy's future offspring.
Exiles/Weapon X
As one of many super-beings to become unstuck in time, a version of Remy was summoned by the Timebroker to join Weapon X and succeeded Sabretooth as leader of the team. Weapon X was the more merciless of the two teams that were hopping around the dimensions in order to fix timelines gone wrong.
Very little of Remy's native reality was revealed, the only thing being that he was married to a Storm that had died, which explained the effect that one of his teammates was a teenage Ororo had on him. Later, during one of Weapon X’s missions, he was forced to kill another counterpart of the woman which tore him apart.
Although he was a darker character than his 616 counter part Remy was unlike most of his teammates in the fact that he wasn't totally ruthless or a psychopath. So when Hyperion, a complete psychopath, became the team's self-styled leader Remy fought against him, which cost him an arm. He then joined up with the Exiles, who were stuck on the same world, in order to stop the threat Hyperion and his group posed. They managed to kill Hyperion, though Remy had to sacrifice his life to accomplish this.
Ultimate
In the Ultimate universe Remy LeBeau was a runaway who was abused by his father. He was a charming mutant thief, who was willing to do the right thing despite his past, which he proved when he helped save a little girl from the murderer Hammerhead. Remy's past seems to be checkered though, despite his good nature, as he has a past with a gentleman named Essex who murdered more than one mutant. He was also distrustful of do-gooders and refused the X-Men's offer to join them. He believed that the roof and warm bed that Xavier offered came with the price of late night visits from the professor.
Remy later took on a commission from Fenris to abduct Rogue, however they fell for each other despite the circumstances of their meeting. Eventually, upon realising what Fenris wanted with Rogue, he helped her escape and they became partners in crime, Rogue having left the X-Men to be with him. However their good times did not last, as Remy was mortally wounded while defeating the Juggernaut and then absorbed by Rogue, which killed him.
Rogue kept Remy's eye and some of his personality, his powers overlaying hers and cancelling them out, and she began to use cards as a weapon much as he had. Most recently however his powers and personality have faded away, leaving her the same as she had ever been.
X-Babies
The X-Babies were originally a team of real X-Men who had been deaged by Mojo, who wanted them to star in one of his shows. Remy was not a member of the team at this point and so was not made an X-Baby.
However, once the X-Men had managed to escape and re-age, Mojo decided that he wanted to create his own set of X-Babies to continue to catch the high ratings. Remy was a member of this team with Archangel, Bishop, Cyclops, Iceman, Rogue and Storm.
After Mojo was killed the new regime decided to cancel the X-Babies, believing that there was no place for them in the new entertainment-free regime. Two executioners, Gog and MaGog, were sent after them. However the X-Babies managed to escape to Earth, where they encountered the real X-Men and enlisted their help to defeat the pair. The X-Men were finding it a difficult battle, and the executioners were stopped just before killing the X-Babies by Dazzler, whose husband Longshot was aiming to take leadership of the Mojoverse and had Gog and MaGog's loyalty. She revealed that the only way for them to be safe was for the X-Babies to go and live with her until Longshot had succeeded in his task. This is the last that has been seen of this group of X-Babies.
What If? II #100
Remy betrayed his X-Men teammates by stealing information from Cerebro and giving it to Mister Sinister in exchange for a piece of the cure to the Legacy Virus. Mister Sinister also informed him that he had a cure to Rogue's powers and Remy travelled under New York City to retrieve a tithe box for Sinister. When Rogue downed the vial containing the "cure" that Sinister had given Remy, she kissed him and drained the life from his body, killing him.
What If? II #106
After Remy's past connections with Mister Sinister were revealed during the trial in Antarctica, he was left there by Rogue. He eventually made his way to Paris, where the X-Men found him and argued over what his fate should be.
Wolverine suggested that he and Angel duel for his life, in the Morlock fashion, but Angel spared Remy death in favor of shunning him from the X-Men forever. Marrow on the other hand, having found out that Remy was responsible for the death of her people, wanted death for him and threw a bone projectile that impaled and killed Remy.

Wha...Huh? (2005)
When Cyclops got an eye infection and tried to fire an optic blast, he just fired a bunch of blood from his visor due to the infection. Remy in this universe does not seem to be any different to his Earth-616 counterpart.
Millennial Visions 2000 - "Universe Rex"
Remy and all of the other X-Men portrayed as dogs.
Millenial Visions 2000 - "X-Sentinals"
While most of the injuries that the X-Men took during their tenure of battling evil were reversible, that was not always the case and cybernetics came in to play. Although it may have started as a damaged limb here and there eventually their whole bodies were replaced, as they became too old to fight.
Their consciousness was downloaded into robot bodies, modeled after their original flesh bodies to maintain their visual identity.
Eventually, after centuries, the mental facilities of these robots became overloaded and they were left with only one purpose... to save mutantkind by wiping out the humans.
Marvel Zombies
It started with a flash in the sky and a ripple through the clouds. The hunger came to feed, and feed it did until the Marvel Heroes were no more. They were replaced by soulless monsters, driven only by an insatiable hunger for human flesh. Remy became a hungering zombie, much like many of the other Marvel Heroes.
