As far as we know the Remy LeBeau of Earth 616 has no descendants. However in alternate universes this has not always been the case. Listed here are the descendants of those alternate Remy LeBeaus, both biological, adopted and suspected.

Biological Desendants

Oliver LeBeau X-Men: The End	Bekka LeBeau X-Men: The End
Olivier takes after his mother, Rogue, more than his father, having a quick temper and loving to fight. Unlike his mother though, he is more interested in the martial arts than brawling, showing the same finesse and style in fighting as Remy and showing considerable skill given his age. It is clear that he has had training and practices often with his father. It is unknow what, if any, mutant abilities he has, since Olivier is too young to have manifested them.	Bekka takes after Remy, whom she adores, far more than her mother. She had his patients and appears to be far calmer than her hot-headed brother. She seems to have a love of music, particularly Jazz. She is also close friends with the Frost-Summers children. As with her brother it is unknow what, if any, mutant abilities she has, being too young to have manifested them.
Medea Millenial Visions
Medea is the daughter of Remy and Ororo Monroe (Storm) and posseses the ability to shoot rapid-fire chain lightning, a mixing of her parent's powers. She is a member of a team of X-Men led by Kitty Pride.

Adopted Desendants

Lucas Bishop X.S.E Future Timeline/Earth 616	Raven LeBeau Mutant X
Bishop was initially adopted by the Witness when he was a young child, although it is unknown for how long or how he ended up in the Witness's care while his sister stayed with their Grandmother. Eventually he was reunited with his family and lived with them until their Grandmother died and they were forced out on to the streets. Going on to join the Xavier Student Enforcers, he eventually ended up in the Witness's debt in an attempt to save his sister, and lived with the man as a guard for a year. He would later return to him in an attempt to glean information about the death of the X-Men, before ending up in the current Earth 616 Universe.	Raven was one of two children that Sinister hired Remy to steal, intending only to keep the boy and dispose of the girl. Remy refused to do so and instead adopted her alongside Belladonna, whom he had remained with in this reality. Although Sinister let Remy keep her, after a battle, he warned that one day he or someone far worse would try to take her. This happened years later when S.H.I.E.L.D was given the Guild's location by Julian Boudreaux and killed Belladonna, capturing Raven. Remy did everything in his power to find her, including joining the Six, and then abandoned them to protect her once he had. It is unclear what abilities she might posses, but it is known that her power levels are off the chart.

Suspected Desendants

Arcadian Marvel 2099	Plague X-Men Millenial Visions
Arcadian was one of the reanimated Undead that the X-Men of 2099 faced. It is never stated who exactly he was, or who his parents were, but it is inferred that they were Rogue and Remy. There is various evidence pointing towards this conclusion including his red eyes, the fact that he wears a trench coat, his speech pattern being a mix of Cajun and Southern drawl, throwing charged tarot Death cards, fighting with a Bo, and references to a thieving father. Some thought that he was Remy reanimated, but it was explained that he died around the year 2040, and he still had the appearance of a young man, so that was debunked.	Plague is commonly believed to be the daughter of Magneto and Rogue Darkholme (a single entity consisting of Rogue and Mystique), however when it came to light that the Rogue personality was having an affair with Remy, it threw in to doubt whom her real father was. Plague has the ability to create tiny robotic viruses, which she termed Micro-Sentinals, and control people with them.

Other Desendants

Charles LeBeau
Charles LeBeau was the child that resulted in a Danger Room session that Rogue ran to see what life married to Remy and living in suburbia would be like. As a Danger Room simulation he has never actually been real.
