Bentley's crossbow was his main weapon in Sly 2: Band of Thieves. It was replaced in Sly 3: Honor Among Thieves and Sly Cooper: Thieves in Time by his wheelchair, which he put the dart shooter into the arm of the chair.
It shoots sleep darts through Bentley's binocucom, and he could use it as a melee weapon. It had a number of power-ups assigned to it, such as the Size Destabilizer. Bentley does not use his crossbow as a melee weapon in Sly 3 or Thieves in Time, rather, he uses his wheelchair to spin around and hit enemies and objects with the wheels.
- In concept art of Bentley from Sly 2, the crossbow has a light bulb-type device on the end. What this would have accomplished is unknown.
