James Patrick Sullivan, commonly known as "Sulley," is a main character in the animated film "Monsters, Inc." and its prequel "Monsters University," produced by Pixar Animation Studios. Sulley is a large, furry blue monster with purple spots, short horns, and a tail, and he is known as the top scarer at Monsters, Inc. He works alongside his best friend and assistant Mike Wazowski. Sulley is characterized as a talented scarer who initially competes with a rival named Randall Boggs but later develops a strong friendship with Mike. The energy in their world is generated by capturing the screams of human children, though the film reveals that laughter is an even more powerful energy source. Sulley also has a gentle, kind-hearted personality beneath his intimidating appearance, and during the story, he develops a close bond with a human child named Boo. The character evolved during the production, originally named Johnson and designed differently, before becoming the beloved Sulley with 3.2 to 14.5 million hairs for animation realism. Sulley is featured in multiple related media including movies, TV series, shorts, video games, advertisements, and merchandising, making him an iconic figure in Pixar's creations.
