The Beast was a huge serpent that Sly Cooper encountered in Haiti. During the job "The Lair of the Beast," Sly explored the Beast's territory in search of a treasure key, only to end up running for his life when the Beast awoke. Due to its tremendous size, the Beast could not be damaged. Sly later used the Beast to bash through a barricade to gain access to more of Mz. Ruby's lair.
It had red and yellow scales, red-pink eyes and razor sharp teeth.
The beast is very large and flexible. Sly's cane appears to have little to no impact on it.
- The Beast is a very large sea serpent, possibly larger than Clockwerk.
- Due to its fearsome and vicious nature, nearly every character fears it, including Mz. Ruby, who keeps it in a large swamp cage with one of the treasure keys.
- When Sly opens the three-lock cage in Haiti, it comes out and destroys a large gate that blocks the path to the Ghost Production Facility.
