Penelope is a mouse from Holland who founded the ACES Competition. She flew and fought under the alias "Black Baron" during her career, as whom she gained both fame and infamy. She was later exposed by the Cooper Gang, after which she joined them as their RC specialist up to and during their mission to access the Cooper Vault. During this time, Penelope developed a relationship with Bentley, and following Sly Cooper's disappearance, she became his pseudo–wife and partner in crime for the next seven years before joining forces with Cyrille Le Paradox and giving him access to the time machine that they created in an attempt to sever all of Bentley's ties to the Cooper Gang and unlock what she believed to be his full potential, which was implied to be world conquest.

She is voiced by Annette Toutonghi.



Little is known about Penelope's early life, other than her apparent enormous wealth and her Dutch nationality. As her interest in plane fighting grew, she invented a disguise she called the "Black Baron" to get past competitions' strict age limits. She still identified herself online as Penelope, but no one was the wiser about her double life.

The Black Baron soon became a celebrity, and Penelope found her wearing the costume and assuming the alias more and more often. At some point, Penelope wanted a challenge to her expert skills. So, she set up a yearly international competition called ACES in an effort to attract worthy opponents. Every year she would win the competition, either by shooting down everyone else or getting her gunships to shoot down anyone who was about to win.

Joining the Cooper GangEdit

When the Cooper Gang met Penelope online, they expressed their interest in a specialist with remote-controlled inventions, something that Penelope was also very adept with. She gave false information, claiming to be one the Black Baron's mechanic, but told the Gang that if they wanted her on the team, they'd have to beat the Black Baron in the upcoming ACES competition. She did not anticipate them to potentially win, as she had full trust in her piloting skills as well as her tricks. The Gang accepted her challenge and traveled to Holland.

Some time before the ACES Semifinals, Bentley contacted Penelope via ham radio requesting her help to defend the Cooper's Hangar from Muggshot's team of pilots' attempt to destroy their plane. Penelope, who was extremely against any forms of cheating between teams (even as the Black Baron), fully supported the Gang in defending the hangar.

During the Finals of the competition, Sly managed to nearly destroy the Black Baron's biplane, and the latter called in his gunships and a passenger plane for backup. Bentley, having anticipated the gunships, utilized the nearby windmills to destroy them, and Sly battled the Black Baron on the left wing of the plane. The costume was destroyed and Penelope was revealed to be inside it. She later explained the purpose of the suit, and joined the Cooper Gang without hesitation.

The Cooper Vault HeistEdit

Between her joining the Cooper Gang and the heist itself, Penelope assisted in recruiting two more members to the Gang - the Panda King and Dimitri - through the use of her RC devices. She was captured by Captain LeFwee, who had planned to make Penelope his wife until the Gang intervened. Penelope even demonstrated her ability in sword dueling against LeFwee on his ship's mast, the latter of whom lost and fell to the ocean. She also realizes she holds strong feelings for Bentley, leading her to heroically saving him and becoming his girlfriend.

As part of the heist, Penelope was crucial to eliminating the threat of guards in Sly's path as he climbed his way towards the Cooper Vault. After the heist failed, Penelope utilized her RC car to destroy the nearby radar towers; had she not, Sly - who later used his biplane to clear the skies of enemy fire - would have been under attack by homing missiles.


After the heist was a success (even though Sly had disappeared) and the Gang disbanded, Penelope remained with Bentley and the two formed a relationship. They worked on a number of inventions, the most notable of which was a time machine. After just finishing the time machine, Penelope just vanished, much to Bentley's dismay. Bentley later discovered that the Thievius Raccoonus was beginning to disappear right before his very eyes, so he had to put off searching for Penelope to get Sly and Murray back together to save the Cooper legacy.

As it turns out, Penelope's disappearance was somehow intentional; Cyrille Le Paradox had hired her to steal Bentley's time machine plans and to create a completely separate time machine. Bentley's suffers from a tragic flaw: it requires an item from the era the user wishes to travel to. Penelope's version does not - the year itself can just be input. Le Paradox also entrusted Penelope to steal Sir Galleth Cooper's cane and stand guard over Medieval England, using a new suit, The Black Knight.

Penelope's intention was to double-cross Le Paradox and convince Bentley that the two of them could be the greatest minds in the world, using their combined intellect to make millions in weapons designs. Bentley, however heart-broken he was at Penelope's betrayal, stuck by his friends and their code of honor. Disgusted by her greed and rudeness to him, he realized the truth that she was completely blind to--that Le Paradox was the one calling the shots, not her.  He defeated Penelope and her suit with his own (made from parts of the Moat Monster), and by the end of the game, she was sent to Paris's highest-security prison...only to escape sometime later, no doubt using her mechanical prowess to do it. But recently, Bentley has been receiving some very strange postcards, with Penelope's symbol (a pink mouse face) on the picture.


Penelope makes her first appearance in MCF: Families Reunited at Last: Switched Minds in which she had accidently switched minds with a boy named Ash, a pokemon trainer, after she, Le Paradox, El Jefe, Toothpick, The Grizz, and Miss. Decibel tried to use the machine that switch the Cooper's, Ratchet's, Clank's, Jak's, and Daxter's minds with some kids in an attempt to get skills of a master thief. She and the other villains tried to attmept crimes in the kids bodies, mainly by stealing valuables recovered from the Titanic but Ash's Pikachu saw through the ruse and eleticuted them. The MCF girls, kids, heroes, and Wing were able to return everyone to their right bodies during the witch's moon but Penelope, Le Paradox, El Jefe, Toothpick, The Grizz, and Miss. Decibel escaped right under their noses and took a special gift meant for Starz that give each of the villains powers and Starian star tattoos over their right eyes.

She appears again in MCF: Families Reunited in The Medical Mayham in which she used special medical syrum to cure sick people at first but then it turns them into robots from the inside out. Through she was stopped by the MCF girls, Jake Long, and Spud, Penelope got away with Haley's dragon powers which she had stolen from Haley when she was a robot. However, why she was after the power is currently unknown.

Penelope is set to appear in MCF and the Cooper Caper as one of the possible villains who kidnapped and give a 'gift' to Princess Vivian that starts to suck the life out of the princess. If Penelope is the one to do so, however, it will not be reveled until the story is written.


Penelope initially comes off as a nice and outgoing person. She enjoys utilizing her RC talents against enemies, and while doing so she can get a little excited. While Penelope had only been a member of the Cooper Gang for a short time, she was dedicated and loyal to her new-found friends, eagerly supporting them whenever they needed help. Unfortunately, her lack of physical prowess and abilities makes her rather timid when actually confronted by an enemy, but when someone she loves - namely Bentley - is threatened, she becomes a powerful combatant.

Unfortunately, at some point during her relationship with Bentley, despite the events that took place during Sly 3, she somehow became possessed by the belief that Bentley was being held back and controlled by Sly's morals. She began to develop a similar mindset to Dr. M, despite once being a moralist herself when she was an extremely firm opponent of cheating during the ACES competition. Of course, it's possible that her dislike for cheating and her violent reprisal against those who betrayed her Black Baron persona were a result of them going against rules she had set for the tournament, but only added to the point of her being moralistic. This is also backed up by her thinking in a way that Sly is evil and that his thieving capers are nonsense and for his own selfish gains, drawing a parallel to Carmelita. With their combined intellect, Penelope started to believe that she and Bentley could have made billions in weapon design, and they could have ruled the world. She began to use and betray anyone to get what she wanted; in some cases, drawing a parallel to Neyla. She also began showing a more aggressive and angry side of herself, prominently when trying to finish off Sly and then, after a failed attempt to reason with her, tried to waste Bentley as a means of making their breakup offical.

She also became surprisingly cruel and gained a dark sense of humor as she even went as low as to torture Sir Galleth physically and mentally by putting him in the circus, and even joking about making a rug out of what was left of Sly once the Moat Monster was done with him, or turning the Cooper Van into a clown car, even saying behind his back that she finds Bentley "cute when he's being dumb".

At this point, Penelope's true character is a mystery. She also seems to be huge on masking her identity. Whether these are her true colors that were hidden from the Cooper Gang for a period of time or that they were somehow newly-developed is unknown, and disguises like the Black Baron or the Black Knight may not have been her first. Some might even think that Penelope might not be her original name. Even how she obtained her skills is a complete mystery. Who Penelope really is may be unknown for quite some time.

Powers and AbilitiesEdit

Other than boxing or sword fighting, the latter of which she probably had to self-teach quickly in order to fight LeFwee, Penelope does not have much in terms of physical abilities. This makes her a potentially easy target when out in the field, shown by her constant capture by certain enemies in Sly 3. To make up for this shortcoming, she has multiple fields in technology, including piloting, using remote-controlled devices, and machinery. She is also capable of using disguises to get through certain bumps in the road. In her debut, she mostly only utilized her RC capabilities, using the RC Car and RC Chopper. Where she acquired any of these talents is unknown.


  • She is the only member of the Cooper Gang to later betray it. Neyla was the first to betray the gang but she wasn't an offical member.
  • According to some concept art for Thieves in Time, Penelope was supposed to remain a protagonist at one point in development, as confirmed by the scrapped mole character and Penelope's revamped original design.
    • What caused the creators to make her a villain is still unknown.
    • In that same piece of concept art, there is a crazier version of the evil Penelope alongside her current design. This was scrapped because she looked too obvious, and the developers needed a design that made it hard to tell she had become a villain.
  • Penelope is the only female character in the series that has been flirted with and admired by more than one male character in the Cooper Gang, namely Bentley and Dimitri, though at first she only had eyes for Sly.
  • She is the only character positively known to have escaped from prison in the Sly Cooper series while Muggshot's possible escape is unconfirmed and unknown.
  • In her original design from the third game, she didn't have her tail. It was added later on in the fourth game.
