Clockwerk is the arch-nemesis of Sly Cooper in the "Sly Cooper "game and film series. He founded and leads the villainous group Fiendish Five so that he can someday destroy the entire Cooper family.
Clockwerk appears in all four video games and the "Sly Cooper" film. He replaced his mortal body with machinery and appears as a large metallic eagle-owl with golden claws and light beaming from his eyes. The arch-villain kills Sly Cooper's father and steals the Thievius Raccoonus, a book containing the Cooper family's thieving secrets. He obsesses over becoming superior to the Coopers. Eventually, Sly Cooper defeats and kills Clockwerk.
