James P. Sullivan (better known as Sulley) is the protagonist of the 2001 Disney•Pixar animated film Monsters, Inc. and the deuteragonist of its 2013 prequel, Monsters University. He was a renowned scarer at Monsters, Inc., where he works alongside his partner and best friend Mike Wazowski. Sulley's world gets turned upside down when he becomes the accidental guardian of a human child (whom he dubs "Boo"). In working to return Boo to the human world, Sulley manages to uncover a company conspiracy while also solving an energy crisis that plagued the city of Monstropolis.
In "And Then There's Fraud", Cleveland Brown shows Joe Swanson a picture of Sulley on his phone, thinking it's "the guy we're talking about."
