Penelope

Penelope is a character from the Sly Cooper series first introduced in Sly 3: Honor Among Thieves  voiced by Annette Toutonghi. She initially appears disguised as the infamous pilot, The Black Baron, but is unmasked by  Sly Cooper  towards the end of the aviation Tournament and decides to join the gang as the RC expert.

She is an anthropomorphic mouse who posseses an RC flight prowess which suprasses that of even Bentley. Discovered by Bentley in the Thiefnet  chatroom Penelope refused to join the gang until they proved themselves to be 'the best' and defeat her current 'employer' The Black Baron. Working together the gang shot down the Baron's plane at which point Sly engaged him in a battle of fisticuffs on the wing of another, much larger plane. After being outmatched he is unmasked and revealed to be Penelope in disguise using the mask of the Baron to enter tournaments she was barred from due to age restrictions (leading most fans to believe she is quite young); after Penelope won her first battle disguised, the Black Baron became a dog fighting enigma, and she soon found she no longer needed to keep up the appearances of the Black Baron.
