List of Monsters, Inc. characters

This is a list of characters appearing in the film Monsters, Inc.

"Boo"


Boo is a human child who is kidnapped from her room by Randall. Much of the film's plot follows what happens as Mike and Sulley try to get Boo back to safety. When she first appears, Boo is very attached to Sulley but he is not so keen. But as the film progresses, he develops a bond with her. Boo's parents are never seen and it is not clear what happens in the human world when she is missing. In the film, Boo tries to get to Sulley while he is showing "newcomers" what it's like to be a top scarer, and Boo gets scared and runs in a corner. Sulley tries to comfort her, and then sees the pictures on the screens. Waternoose discovers the "child"(as he calls it),and sends Mike and Sulley into the human world, which makes Mike mad because they won't be there if Sulley listened to Mike. Eventually, Mike and Sulley make it back to the Monster World, through the village. Boo is the cutest little girl and the only cute girl in the movie.

Celia Mae


Celia Mae is Mike Wazowski's girlfriend. She has snakes for hair, like the Greek mythological creature Medusa. In the movie, Celia is celebrating her birthday, so Mike invites her to an Asian-like restaurant, Harryhausen's (named in honor of legendary monster maker Ray Harryhausen), but due to Boo, the place is contained by the CDA. One device that is made to make a large dome that would get rid of fatal germs, but could harm people without CDA armor, which is why Celia came back to work the next day with serious injuries. Although mad at Mike, she finds out about Randall trying to capture Mike and Sulley, so she caused a crowd to block his way.

Henry J. Waternoose
Henry J. Waternoose is the director of a famous scaring company called Monsters Inc. He is one of three owners, all cast down from lineage. Sulley, being the company's biggest "producer" and Waternoose's protegée, is asked to come down to the scare training room and show the new employees how scaring should be done. Waternoose is behind a plot to increase the dwindling scare production along with Randall, the company's second-biggest producer, and a less-than-savory fellow worker. When Waternoose finally figures out that Sulley and his teammate and pal Mike Wazowski have the child, Waternoose is forced to send Mike and Sulley to the Himalayas. In the end, Randall is taken care of by Sulley and Mike. Waternoose corners Sulley in what is he believes to be Boo's bedroom, and announces his intention to "kidnap a thousand children" if that's what it takes to keep the company alive. The room turns out to be the training room, where the training sessions are observed, recorded and played back to analyze the trainee's performance. With this incriminating evidence, Waternoose is taken away by the Child Detection Agency (CDA). Henry J. Waternoose is the last animated character voiced by James Coburn; his first was Looten Plunder from ''Captain Planet and the Planeteers.

James P. Sullivan


James P. "Sulley" Sullivan is a large, furry blue monster with purple spots, voiced by John Goodman. When he is first seen, Sulley is the top scarer at Monsters, Inc., responsible for generating the scares that provide power for the city of Monstropolis along with his partner, Mike Wazowski. During the course of events, Sulley accidentally allows a small girl, Boo, to enter the Monster World. He attempts to return her to her room, but to no avail. When her presence becomes public knowledge, he hides her in his home, eventually coming to realize that she is not as dangerous he has been led to believe.

Invisible Snowman


The Invisible "Invie" Snowman finds Mike and Sulley stranded in the snow after Waternoose kicks them out. He makes them safe in an igloo. Invie makes some lemon snowcones, but Mike destroyes them by chucking them at Sulley. He tells Sulley 3 days until it's back to Monsters, Inc. Sulley gets their by a ski. Sulley passes Invie when he gets more snowcones.

Mike Wazowski


Michael "Mike" Wazowski is shown as a sort of Cyclops monster in the shape of a tennis ball, with one large green eye. He has two small horns on the top of his head. His arms are dangly, with four fingers on each hand. His legs are skinny with big feet. He was voiced by Billy Crystal. He and Sulley are best friends and are a team in the Monsters Inc factory. He is initially much more reluctant towards Boo, and although he does not form as close a relationship with her as Sulley, he warms up to her and makes it possible for Sulley to find her again in the end of the film. He made a cameo in Dad Day Afternoon / Scary Poppins where he was chasing Irwin and Dick

Randall Boggs

Children's screams are collected and used to power the city. Randall acts as the direct rival of the movie's protagonists, James P. Sullivan, and Mike Wazowski, and is in competition with them for the glorious post of Top Scarer. However, Randall has also constructed a "Scream Extractor," and attempts to kidnap a human child in cooperation with the company's leader, Henry J. Waternoose, with the hopes to eventually rise to the leader of the company. He is defeated after a chase through the factory,where Boo and Randall escape into a door, and Boo begins to hit him with a shovel, making him turn colors,then chokes him, where he is defeated.
