Who is Gambit? Well, read and learn my friend. Remy LeBeau was born in New Orleans, Louisiana. He was kidnapped from the hospital where he was raised by the Thieves Guild, and given to the Antiquary as a tribute.
They referred to the child as "le diable blanc" ("the white devil") and believed he was prophesied to unite the warring Thieves and Assassins Guilds. Soon after, Remy was placed in the care of Fagan's Mob, a gang of street thieves who raised the child and taught him the ways of thievery. After living as an orphan on the streets, a 10 year-old Remy attempted to pick the pocket of Jean-Luc LeBeau, then patriarch of the Thieves Guild. Jean-Luc took the boy off the streets and adopted him into his own family.
Remy's biokinetic charging abilities manifested early in his teens, although he kept it secret from his family and friends, practicing his powers away from prying eyes. When he was 15, he accompanied his best friend Etienne Marceaux on his "Tilling", the ritual initiation test of the Thieves Guild. However, it went awry as they were assigned to steal from the powerful immortal mutant Candra, who quickly captured them. Candra recognised Remy from an encounter that had taken place in her past but in his future (due to a time travel mission to the 19th Century Remy would take as an adult) and sold them to the deformed, mutant gangster and child slave trader known as the Pig, who planned to sell them and others their age on to HYDRA as boy soldiers. Remy used his powers to escape their holding pen, but the physically enhanced Pig quickly caught up to them. Remy discovered his signature attack when he picked up a playing card that the downed Etienne had dropped, charged it and threw it in the Pig's face, taking out his eye. Finally escaping his clifftop headquarters by diving into the sea, Remy was ultimately rescued by the Guild but Etienne instead drowned. Gambit is a very crucial member to the X-men, a Marvel superhero team of mutants.
