Cyrille Le Paradox is a character and main antagonist from Sly Cooper: Thieves in Time.
Cyrille is a member of a long line of thieves, the Le Paradox clan, which is similar to Sly Cooper and his family. Before Thieves in Time took place, Cyrille's father had planned to steal the world's biggest diamond, but he was beat to the punch by Sly's father. This made Sly's father a legendary thief, but Cyrille's father got caught and was arrested.
Because his father was in jail, Cyrille didn't have a mentor in the family business and Cyrille himself got caught during jobs and arrested. He used his know-how to bribe inmates to do his dirty work and ended up using his contacts to set up his own group after being released. He maintained the appearance of a law-abiding citizen, posing as a treasure collector, although he was a dealer in the black market.
His hatred for the Cooper Clan was immense, since his family business was ruined, so he planned to go back in time and erase the existence of the Cooper Clan throughout time. This plan, which was to incapacitate the Coopers in some way, as well as steal their canes, would have been successful if it wasn't for the Cooper Gang. It wasn't until Arabia that the player learned of Le Paradox's plans, which was to use Miss Decibel and members of the Forty Thieves to forge documents to fake a royal heritage, essentially making Cyrille rich and powerful in the present.
In the end, Cyrille's overconfidence eventually got himself into a battle with Sly, who defeated him in battle. He managed to escape by stealing Sly's Paraglider, but he got sucked into one of the propellers and fell in the ocean. He survived, but was subsequently arrested and placed in an odor-proof jail cell.
