Bio: Ever since he was a kid, Sulley has always dreamed of becoming a scarer at Monsters Inc., wanting to follow in the footsteps of his father, the legendary scarer Bill Sullivan. In the 4th grade, he would befriend Mike Wazowski and the two would remain inseparable ever since. They went to the same middle school together, the same high school together, they even went to the same college together, Monsters University. Unfortunately, due to a incident there, the duo ended up getting expelled. But not long after that, the duo would end up working at their dream company of Monsters Inc...but as mailroom workers. But over the years, they would eventually rise to the ranks, with Sulley becoming a scarer (and a top one at that) and Mike becoming a scaring coach. But everything changed when they encountered a girl from the human world named Boo. At first, Sulley wanted to get rid of her, but overtime, he would eventually grow to care for her. And thanks to her, he and Mike discovered that laughter was a much more powerful source of energy than screams. And after series of events, including the exposing of a inside conspiracy, laughter became the main source of energy of Monstropolis and Sulley became the CEO of Monsters Inc., after the original CEO, Henry J. Waternoose III, was arrested for said conspiracy. Short time later, Monstropolis found itself under attack by the Fractured, and Sulley, with some tech invented by Mike and the company laboratories, decided to step up and defend his city. This attracted the attention of the Guardians, who offered both Mike and Sulley places on their team, which they accepted.

Powers and Abilities: Sulley wears a special high-tech exoskeleton that not only amplifies his already great strength, but also allows him to take tons of damage and pull out a high-tech door shield that can shoot bursts of energy when hit enough times.
