The Klaww Gang was an international group of criminals that produced and distributed illegal spice. After some time, they utilized the stolen components of Clockwerk to accelerate spice production and for their own personal schemes. They were eventually defeated by the Cooper Gang.
- Dimitri's nightclub (closed down)
- Rajan's palace
- Spice temple
- Contessa's rehabilitation prison
- Contessa's castle
- Nunavut Bay
- Lumber camp
- Arpeggio's blimp (destroyed)
The Klaww Gang's apparent plan had been to use illegal spice for profit. While Rajan would produce the spice in India and ship it around the world, Jean Bison utilized his Iron Horses to spread the shipments across the North American continent. The Contessa used her incarceration facility in Prague to hypnotize criminals who consumed the spice into revealing the location of all their stolen loot. Dimitri used his nightclub to assist in having the citizens of Paris purchase it. Once they stole the recovered components of Clockwerk, founder of the Fiendish Five, and adapted the components for their own use via Arpeggio, their spice operation accelerated in profit; Rajan was able to produce ten times the amount of spice than before, the Contessa was able to increase her hypnotic abilities, and Jean Bison was able to improve his trains so they could run endlessly day and night. Clockwerk's body was also able to allow Dimitri to begin a counterfeiting operation, with the refined alloy in the tail feather's composition doubling as printing plates.
The actions of the Klaww Gang earned the attention of Sly Cooper, who began hunting down each of them to recover their stolen Clockwerk Parts. However, Arpeggio as part of his own grand design, planned on luring the Cooper Gang to steal the parts from his cohorts, and eventually hoped to steal them all back and keep them in his possession. Rajan would grow the spice as part of the original plan; meanwhile, Arpeggio would assign Jean Bison to convert the northern lights into energy, store it in a battery, and ship the spice to Paris, where Dimitri would distribute it throughout the city. Hypnotic devices created by the Contessa would be powered with the Northern Light energy to deliver the same hypnotic frequencies as her own devices in Prague (but at a far longer range since the ones in Prague work at close range to specific people). After integrating these methods into his blimp, Arpeggio would fly over Paris and the spice consumed by Paris' citizens would allow the Klaww Gang to enact mass hypnosis, putting them into a violent rage.
It is implied this plan of Arpeggio's was given the rouse as being an extension to the original and was to be used to help increase the purchasing of spice for their operation. In reality, the rage generated by the hypnosis would create a massive hate generator which would empower Arpeggio once he merged himself with a reassembled Clockwerk to become immortal. It is unknown what his plans were once he obtained immortality.
After fully developing the plan and having purchased the Clockwerk Parts from Jean Bison, Arpeggio set his blimp on course to Paris from Canada and began reassembling Clockwerk for the final stage in his concocted vision. Sly Cooper, having infiltrated the blimp, unintentionally locked the Clockwerk pieces together instead of breaking them apart and alerted Arpeggio of this new development. Impressed by Sly's actions, Arpeggio thanked Sly and prepared to merge himself and finally execute his plan. Immediately, Neyla, Arpeggio's protégé, betrayed him and merged herself with Clockwerk's body instead. Dubbing herself "Clock-La", she crushed the helpless Arpeggio in her beak, killing him. With the death of Arpeggio and the later destruction of Clock-La, the Klaww Gang collapsed without any members left active.
After serving their time in prison, each member of the Klaww Gang went their own way.
- Dimitri became a dance teacher on a cruise ship after serving time and later ended up in jail again for an unknown reason as shown early in Sly 3. He was freed and later recruited to be the frogman for the Cooper Vault job.
- Rajan started the Karpet King rug dealership franchise in North America.
- The Contessa became the most successful real estate broker in the Greater Milwaukee area. As seen from her customers, it seemed her talents in hypnosis helped.
- Jean Bison began to work for the EPA and ended up frozen yet again on a mission to save baby penguins.
When the Klaww Gang stole Clockwerk and scattered the parts around the world from the Museum of Natural History in Cairo, Egypt, they divided the parts among the five of them. The parts they took depend on what was most useful to the member.
- Clockwerk's Tail Feathers: Used by Dimitri, the Clockwerk Tail Feathers were put to use as printing plates for his Paris counterfeiting operation. Because of their metallurgical properties, the Tail Feathers would have never worn out.
- Clockwerk's Wings: Taken by Rajan, the Clockwerk Wings weren't put to any practical use. Instead, Rajan had them mounted on a statue in his palace ballroom, where he hoped they would bring him prestige.
- Clockwerk's Heart: Another of Rajan's parts, the Clockwerk Heart acted as a powerful pump that allowed Rajan to grow illegal spices at much faster rates than normal. Half the Heart was used in this manner, while the other was attached to the end of Rajan's staff, allowing him to unleash electrical attacks.
- Clockwerk's Eyes: Components with powerful entrancing qualities, the Clockwerk Eyes were given to the Contessa, who intended to use them to enhance her own hypnosis machinery.
- Clockwerk's Lungs and Stomach: Given to Jean Bison to transport illegal spice across North America, the Clockwerk Lungs and the Stomach allowed him to keep his Iron Horse trains running all day and night without stopping.
- Clockwerk's Talons: Razor-sharp blades capable of slicing through plates of steel, the Clockwerk Talons were used by Jean Bison in his lumber jacking enterprise.
- Clockwerk's Brain: The final Clockwerk part were given to Arpeggio. He didn't use them for anything like the other Klaww Gang members, as his view of the parts was different.
- Clockwerk's Hate Chip: Clockwerk's power source, the Hate Chip's what gave Clockwerk their seeming immortality. Once it was destroyed, the Clockwerk parts faded into nothingness.
- Throughout the game, the player can listen in on radio broadcasts and transmissions from the various Klaww Gang members which reveal parts of the master plan.
- The Klaww Gang shares a number of characteristics with the Fiendish Five: Arpeggio and Clockwerk are both birds who have great mechanical knowledge and seek immortality, Jean Bison and Muggshot are both massively strong with limited intelligence, The Contessa and Mz. Ruby are both the only women in their groups and are interested in black magic, Rajan is like Panda King because both grew up poor and later convinced themselves and others of their "royalty", and Dimitri and Raleigh both have experiences with piracy (Dimitri's grandfather was robbed by pirates and the former later helps the Cooper Gang in a pirate gig, whereas Raleigh experimented with piracy before joining the Fiendish Five).
- In Naughty Dog's Jak and Daxter: The Precursor Legacy, there is a boss character named Klaww.
- The Klaww Gang symbol can be seen on a box in He Who Tames The Iron Horse outside of Jean Bison's house. It can also be seen on various barrels of spice around their bases.
