James P. Sullivan

James P. Sullivan was one of the central characters and the main protagonist in Disney/Pixar's 2001 film Monsters, Inc. and its upcoming 2013 prequel Monsters University. He is voiced by John Goodman.

He is a large bear-shaped monster with two hooked horns, covered in sky blue fur with purple spots. His best friend is Mike Wazowski, his roommate and childhood friend since at least the fourth grade. Sully was top scarer of Monsters Inc, and was naturally afraid of humans due to their rumored "toxic touch" that could kill the biggest monsters in an instant. Until he met Boo, a human girl who found her way into the Monster world and into the factory. Sullivan, who was initially hesitant became Boo's protector and obtained a fatherly role to the human. Constantly worrying about her and protecting her from harm while at the same time unlocking the secrets that humans were not as deadly as rumored. Starting by treating Boo like a pet, he eventually grew to care for her, the attention drawing away from Mike who became jealous. Randall, Sully's rival attempts to use Boo in an experiment to forcibly extract screams for the growing energy crisis that relies on their cries to provide, and risking his friendship with Mike, Sully comes to her rescue and in the process discovers that a child's laughter is ten times more powerful than their scream. After Waternoose, the current CEO of Monsters Inc is arrested, Sully takes the seat, changing their policy to obtain childrens' laughter instead, apparently turning the energy crisis around.

Sully is about seven feet in height and has a large build, more than a match for any monster. He is kind hearted and very loyal to his friends and loved ones. Very strong, where Sully lacks in book smarts he more than makes up in ingenuity.
