The Grizz was another member of Le Paradox's gang who planned on forging cave paintings in the past, and then digging them up later in the present, making himself a fortune. Le Paradox hired The Grizz to erase the first Cooper, Bob, from history.
Once a child who simply loved to skate, The Grizz eventually turned to the thug life, becoming a graffiti artist and developed a knack for rapping. One time, The Grizz was thrown in jail for his graffiti, but was then promptly bailed out and shoved into the limelight by a pop artist. The Grizz introduced a new style called "Paleo-graffiti", and succeeded, enjoying a short-term of celebrity status. This rise to fame fell fast as people outgrew The Grizz's gimmick and realized it wasn't as good as they once thought. The Grizz was then tossed aside and he was suddenly back at square one.
The Grizz felt mistreated and disrespected by the community, causing him to turn back to a life of crime. He quickly rose to becoming the top art thief on Interpol's most wanted list and was one of Inspector Carmelita Fox's biggest priorities. Using intel discovered by Carmelita, she and the Cooper Gang were able to break into The Grizz's Purple Paw Paint Factory and confront him. Murray would eventually fight and defeat The Grizz, leading to his arrest.
