Fists of Flame

"Turn ordinary punches into fiery ones."

- In-game description

Fists of Flame is a purchasable power-up available for Murray. It first appears in "The Black Chateau" of Sly 2: Band of Thieves, and reappears in Sly 3: Honor Among Thieves and Sly Cooper: Thieves in Time.

Description
The Fists of Flame power-up allows Murray to set his hands on fire and dish out fire damage to any guard he punches.

In Sly 2 and Sly 3, the move has to be assigned to a button (either, , or ) in order to be able to use it. Murray claps his hands above his head to get his fists to catch on fire. The next enemy he punches bursts into flame and dies (except for Carmelita Fox and bosses). If you press the assigned button again before you hit an enemy, Murray will clap his hands again, eliminating the flames in the process. It costs energy from the Gadget Meter every time the power-up is activated, but not when it is deactivated.

In Thieves in Time, the Fists of Flame is changed to a selectable pair of gloves. When the power-up is selected, Murray's hands are perpetually on fire. The catch is that every fiery punch thrown costs energy from the Gadget Meter. Unlike in previous games, a punch thrown using Fists of Flame does not instantly kill all enemies. To select Fists of Flame, hold to bring up Murray's gadget grid, and then use  to find the gloves before releasing.

Trivia
