Clockwerk was the main antagonist of Sly Cooper and the Thievius Raccoonus, the founder of the Fiendish Five, and a chief villain in Sly 2: Band of Thieves. Residing in Russia, Clockwerk is an eurasian eagle owl and as time passed he replaced his body parts with advanced machinery in the hopes to wipe out the Cooper clan. His motive was to show the world that The Cooper Clan was nothing without The Thievius Raccoonus. He is the arch nemesis of the entire Cooper Family and Sly Cooper. He is arguably the main villain of the Series.
