Amazing! Colonel Reid Cooper's time stopper technique! Press TriangleButton and execute a flash bang that will stun all guards in the world for a few seconds! I can see how this might be useful... and entertaining too!
— Bentley describing the technique[src]

Stun, also called Time Stopper, is a power-up in Sly Cooper and the Thievius Raccoonus. Invented by Colonel Reid Cooper, it can be collected from the 15th and final vault, not counting any blueprints.


Time Stopper is activated by pressing TriangleButton. Sly Cooper will spin his cane above his head before slamming it on the ground. For several seconds after this, all guards will become stunned, unable to move.

A similar move is available to Bentley and Murray in Sly 2: Band of Thieves and Sly 3: Honor Among Thieves, respectively, where it is known as the Temporal Lock.
