Sly 1: Sly Cooper comes from a long line of master thieves (the Cooper Clan) who only steal from other criminals, thus making them vigilantes. The Cooper family's heirloom, an ancient book by the name The Thievius Raccoonus, records all the secret moves and techniques from every member in the clan. On his 8th birthday, Sly was supposed to inherit the book and learn all of his family's ancient secrets which was supposed to help him become a master thief, however, a group of thugs by the name "The Fiendish Five" (led by Clockwerk, who is the arch-nemesis of the family clan) attack the Cooper household and kills Sly's parents and stole all of the pages from the Thievius Raccoonus. After that, the ruthless gang go their separate ways to commit dastardly crimes around the world. Sly is sent to an orphanage where he meets and teams up and forms a gang with two guys who become his lifelong best friends, Bentley, a technician, inventor and a talented mathematical hacker with encyclopedic knowledge who plays the role as the brains of the gang, and Murray, a huge husky cowardly guy with a ginormous appetite who plays the role as the brawns and the getaway driver of the gang. The three leave the orphanage together at age 16 to start their lives becoming international vigilante criminals together, naming themselves "The Cooper Gang". Sly swears one day to avenge his family and track down the Fiendish Five and steal back the Thievius Raccoonus. 2 years later, the Cooper Gang head to Paris, France, to infiltrate Itnerpol (a police headquarters) in order to find the secret police file which stores details and information about the Fiendish Five but during the heist they are ambushed by Inspector Carmelita Fox (towards whom Sly develops a romantic attraction), a police officer who is affiliated with Interpol and is after the Cooper Gang. The gang manage to steal the police file and successfully escapes from her and the rest of the cops. With the secret police file finally in their hands, the Cooper Gang manage to track down the Fiendish Five. Sly2: Two years after defeating Clockwerk, Sly Cooper breaks into the Museum of Natural History in Cairo to steal the Clockwerk parts and destroy them to end his threat against Sly's family for good, but discovers that the parts are already missing. Inspector Carmelita Montoya Fox and her new partner, Constable Neyla, confront Sly, but he escapes before Carmelita and Neyla can arrest him. Before making his escape, Sly hears Neyla suggest that the evidence actually suggests that the Klaww Gang stole the parts for their own use. The Cooper Gang heads to Paris, where the first Klaww Gang member Dimitri is using Clockwerk tail feathers as printing plates to create counterfeit money. Sly and the gang shut the operation down and Dimitri is arrested by Interpol. The gang then heads to India, where the second Klaww Gang member Rajan puts Clockwerk's wings on display at a ball he is hosting. Rajan is also the kingpin of a local crime syndicate that grows and sells "spice", an illegal plant indigenous to the Indian jungle. Also present at the ball are the other Klaww Gang members and several undercover Interpol agents, including Carmelita and Neyla. The gang steals the Clockwerk wings in the middle of the ballroom while a disguised Sly creates a distraction by dancing with Carmelita. After the Cooper gang escapes with the Clockwerk wings, Carmelita blows her cover and starts making arrests. The Klaww Gang flees the scene, and Rajan goes into hiding somewhere deep in the jungle. The gang tracks him to his spice-growing facility in a long-abandoned temple, where he is using half of Clockwerk heart to super-irrigate his spice crops. He carries the other half of the heart on the end of a staff that he carries with him at all times. The gang steals both halves of the heart and incapacitates Rajan, but Carmelita, Neyla and the Contessa arrive. Neyla frames Carmelita of working with the Cooper Gang on the night the Clockwerk wings were stolen. She betrays the Cooper Gang and puts Sly, Murray, and Carmelita under arrest. Sly3: Set a year after the events of Band of Thieves, Sly Cooper, Bentley, Murray, and other unidentified characters attempt to open the Cooper Vault on Kaine Island. Unfortunately, they are intercepted by Dr. M, the owner of the island. Murray and Bentley escape, but a monster grabs Sly. During this scene, Sly's life flashes before his eyes, and the game flashes back. Sly learned that the Cooper Vault was hidden on Kaine Island from one of his father's colleagues, Jim McSweeney. The vault contains the accumulated wealth of the Cooper Clan built up over the centuries. Sly went to find the vault, only to discover that M had built a fortress on the island in an attempt to get at the wealth hidden in the vault. Sly needed additional experts in order to get past Dr. M's extensive security; he needed the Cooper Gang back in action. First, Sly and Bentley seek Murray, who had left the team due to guilt for causing Bentley's leg injury, which would end up paralyzing him. They learn about a mob boss, Octavio, who operates in Venice, Italy, where Murray was. Sly finds Dimitri in a cell at the local police station. He agrees to find Murray if Sly helps him escape. Sly finds Murray, while evading Carmelita Fox, who had become more hateful towards crimes since their last encounter. Murray had become a trainee for a peace-loving figure known as the Guru in order to become more peaceful. Murray refuses to rejoin Sly and Bentley until the canals are clean, the task the Guru gave to him. Sly and Bentley take down Octavio, who had been polluting the canals with tar as part of a scheme to threaten the city into liking opera again. After putting together some plans, they destroy Octavio's comeback recital, but Octavio injures Bentley, making Murray so mad that he quits his training and battles Octavio and defeats him. Octavio is arrested, and Murray rejoins the team.
