The Cooper family have been master thieves for thousands of years, stealing only from criminals. They often assemble other thieves around them, forming the organization known as the Cooper Gang. The Cooper Clan has often clashed with criminal organizations. Their most ancient enemy is Clockwerk, who founded the Fiendish Five.
Known Members
- Slytankhamen II: Sly's ancestor from ancient Egypt, and creator of the Cooper Vault. He had two canes, and used the ability to turn invisible to steal from rich noblemen. He also was skilled at putting up traps that were used in ancient Egyptian tombs.
- Sir Galleth of the Knights of the Cooper Order: Sly's ancestor from the Medieval Time. An honorable knight and cunning thief who fought with a lance with a hook point.
- Salim al Kupar of Arabia: A Cooper hailing from Arabia said to hold the stealth of 40 thieves, a reference to Ali Baba. His weapon was a sword with a curved, hooked blade - sporting a scimitar-like look, but with a much thicker blade. He wore a turban in his Cooper vault portrait, indicating a possible Muslim or Dharmic religion.
- Slaigh MacCooper: The strongest of all of the Coopers, he could break any lock with one blow with his large stone cane. Judging from his Celtic attire in his Cooper vault picture (for example his kilt), he lived in a Celtic region such as Scotland or Ireland.
- Rioichi Cooper: Sly's ancestor from feudal Japan. He created the ninja spire jump. His weapons were two hooked daggers.
- Henriette "One Eye" Cooper: A woman who sailed the seas and stole from other pirates. She had the innate ability to smell gold. Originally wielding a hooked dagger (as seen in the portrait of her in the Cooper vault), it can be assumed that she lost a hand and replaced it with a hook shaped like the trademark Cooper hook (as seen on the pedestal in front of the portrait), an obvious reference to Captain Hook, antagonist of Peter Pan by J. M. Barrie.
- "Tennessee Kid" Cooper: Sly's Western-outlaw ancestor from nineteenth century United States of America. The "Kid" in his name alludes to Billy the Kid, a famous outlaw in the American west. He carried a gun with a hooked handle. Tennessee Kid also invented the rail walk and rail slide.
- Thaddeus Winslow Cooper III: A Cooper who was the most "gentlemanly" thief and a master of disguise - he had a cane similar to Sly's, the only difference being a red ruby-like gem at the end of it.
- Otto Von Cooper: An ancestor of Sly's who was a genius mechanic and skilled fighter pilot. Due to his physical ineptitude, he used that talent to pull off heists, his machines facilitating his thievery. He kept some of his technical blueprints in the Thievius Raccoonus. The propeller blades of his biplane were shaped like the trademark Cooper hook.
- Drake Cooper: He created the knockout dive. This move is available in Sly 2: Band of Thieves
- Sally Cooper: She created the roll move.
- Dev Cooperinda: The creator of the slow motion jumps.
- Chris Cooper: He invented the coin-collecting dive technique. The move comes standard in both sequels, however it no longer collects coins as it makes its impact, rather relying on its brute force to render enemies unconscious.
- Karen Coopergiwa: She invented the coin magnetism technique.
- Rob McCooper: He created the explosive hat mine technique.
- B.F. Cooper: The inventor of the fast motion technique
- Suzanne Cooper: She created the ability to jump out of water.
- Sir Andrew Cooper: He created the thief replica, or "decoy" technique.
- Kelle McCooper: The creator of the electric upgrade of the roll technique.
- Bruce O'Coop: An ancestor of Sly's who was an expert hacker.
- Matthew de la Coopeur: He created the perpetual slow motion technique. This is available in the other two Sly games, but renamed "Thief Reflexes".
- Huckleberry Cooper: The inventor of the ability to move (slowly) while invisible.
- Colonel Reid Cooper: The inventor of the time stop move and the final ability. This is available in the other two Sly games.
- Augustine Cooper: Inventor of the ability to briefly defy gravity.
- Sly's father: He used the same cane that belongs to Sly. Before being killed by the Fiendish Five, he pulled heists with McSweeny and Dr. M, and created a technique to slide along lasers. He is listed in the Disney magazine as having the first name Connor.
- Sly Cooper : Recoverer of the Thievius Raccoonus, he defeated Clockwerk at the age of 18, and then defeated the Klaww Gang, recovering the stolen Clockwerk parts and defeating Clock-La.
Thievius Raccoonus
The Thievius Raccoonus is an ancient book in which every Cooper Clan member over the centuries has recorded their thieving escapades, in addition to instructions on their various moves. It was passed down through the family for generations, but was later stolen and divided among the Fiendish Five. After 10 years, Sly tracked down the criminals and recovered the Thievius Raccoonus, afterwards recording his own adventures in the book. After Sly left the life of a thief behind to strike up a relationship with Carmelita Fox, the book was given into the care of Bentley, who became the first non-Cooper in history to write in the Thievius Raccoonus.
