Arpeggio

Arpeggio was the chief inventor and leader of the Klaww Gang, as well as the mastermind behind the events of Sly 2: Band of Thieves. He was a small British parrot who desired to wield the power and immortality of Clockwerk, Sly Cooper's nemesis. To this end, he manipulated the Cooper Gang into stealing the Clockwerk parts from his fellow Klaww Gang members for him, with the help of his protégée and assistant, Neyla.

He was voiced by Sam A. Mowry.
