Murray has always been special, but in this gear he's gone Special Ops! His tactics are simple, but effective: Never fight on an empty stomach!
― In-game description[src]
Ultimate Murray is an outfit available for Murray to wear in Sly Cooper: Thieves in Time. The outfit can be unlocked by collecting 30 Sly Masks, and was unlocked automatically if Thieves in Time was pre-ordered. Murray is seen wearing the costume in Of Mice and Mechs where he used it to break into the Black Knight's castle by swimming through the moat, despite his inability to swim in-game, and activate some bombs concocted by Sir Galleth Cooper. Like most other mask prizes, they are for appearance only and do not affect gameplay in any way.
The outfit is a tight-fitting gray and blue scuba suit, blue flippers, a black vest over top, a pocket weight belt, a double hose regulator and a rebreather tank on the back. Murray also wears tri-night vision-scuba goggles. On the shoulder of the wet suit is the Sly Cooper logo.
- The night vision goggles that Murray wears are reminiscent of those worn by agents in the Splinter Cell series of games.
