See you in the next world, Sly Cooper.
― Mz. Ruby, during her encounter with Sly Cooper[src]

Mz. Ruby is an alligator who was originally the chief mystic of the Fiendish Five. Her plan was to create an army of ghosts to take over Mexico. She appeared in Sly Cooper and the Thievius Raccoonus as the main antagonist of "Vicious Voodoo."

She was voiced by Presciliana Esparolini.



Mz. Ruby as a child

Mz. Ruby was born into a family of mystics and was feared by other children due to her strange powers. Despite an earnest effort to fit in, learning to summon the undead was the only possible method she had of gaining friends. Years of bitterness led an adult Mz. Ruby to use her voodoo talents for crime to take revenge on the world for fearing her as a child. She became the chief mystic of the Fiendish Five, which allowed the group to break both the laws of man and nature at the same time.[1]

Sly Cooper and the Thievius Raccoonus[]

As a member of the Fiendish Five, she accompanied her fellow cohorts during the attack on the Cooper home and was involved in the subsequent murder of Sly Cooper's parents. She departed with the manuscripts of Slytunkhamen Cooper I and fled into the jungles of Haiti. Mz. Ruby used her voodoo knowledge to create armies of ghosts from bones and body parts, setting them within and around her alligator skull temple.

Despite numerous obstacles, Sly managed to reach Mz. Ruby's skull temple, where he faced off against her in a battle of "Voodoo Simon Says," as he put it. Mz. Ruby was beaten and forced to reveal the location of the Panda King. Her voodoo activities, primarily the creation of zombies, earned her a life sentence behind bars. Years later, after the fall of the Klaww Gang, Mz. Ruby was still in jail, along with Raleigh and Muggshot.[2]


Physical appearance[]

Mz. Ruby is a dark green alligator with a light green belly and mouth, along with sharp teeth, spikes on her tail and dark blue hair. She also has red eyes. Her attire includes what appears to be a pinkish-purple sleeveless shirt, a red bandana on her head tying up her hair, one gold ring on each of her ankles and two of them on her wrists. She also has her fingernails and toenails painted red in addition to the ruby in her belly button, and also wears a gold necklace around her neck. Her appearance is typical of a voodoo priestess.


Mz. Ruby is a particularly cold and dark individual due to years of isolation in her early childhood. Despite her eventual use of magic in order to make friends, she later employed these abilities in a life of crime. She is somewhat maternal towards her zombie creations, calling them her children. Mz. Ruby possesses an eccentric and sadistic sense of humor, quite delighted at the thought of Sly dying. She had ambitious plans to use her dark creations to take over Mexico.

Despite her great power and large build, Mz. Ruby is cowardly and opts to fight Sly from a distance rather than hand to hand. Additionally, when Sly rode on Chumley (at Mz. Ruby's insistence) to get close enough to strike, Mz. Ruby killed Chumley, either out of anger or bad aim. Later, one of the large mosquitoes assisted Sly during the final stage of the battle by allowing him to ride on its back so that he could approach her one last time. This would suggest that the local wildlife was angry at the priestess for poisoning their jungle. Such instances further substantiate how her youth of isolation impaired her ability to care for others.


Mz. Ruby possesses numerous magical abilities including conjuring ghosts, reviving the dead, shooting energy blasts and teleportation, as seen in her battle with Sly.[3] The blasts are so powerful, they killed her servant Chumley and a mosquito in one hit. On top of this, she was able to predict Sly's arrival in Haiti. In the introduction of "Vicious Voodoo," she was seen looking into a crystal ball, suggesting the abilities of a seer.

During the boss battle, Mz. Ruby would make different sounds that were specific to each attack she unleashed, and these were repeated by Sly as he dodged them.[4]

  • square - Dig
  • circle - That
  • triangle - Voo
  • x - Doo

Whenever Mz. Ruby would successfully land a hit on Sly, she would briefly be seen using her belly like a drum, similar to what Raleigh's walrus guards do.
