Monsters University During a class field trip to the energy factory Monsters, Inc., a young, non-frightening monster named Michael Wazowski gets inspired to become a professional scarer. In his later years, he gets accepted into the titular college's scare program, where he becomes acquainted with classmate
James P. Sullivan and his new roommate, Randall Boggs. Wazowski initially dislikes Sullivan for his cocky personality and
slacker attitude, but takes a liking towards Boggs. One day, during an exam in one of their classes, Wazowski and Sullivan engage in a feud. This results in both monsters having to exit the program. However, Wazowski works out a deal with the
Dean to re-enroll in the program on the stipulation that he wins the Scare Games. To enroll in the games, he joins unpopular fraternity Oozma Kappa; in need of one more member, Sullivan joins as well, despite Wazowski's protests. Wazowski and Sullivan begin to form a friendship as they compete together. During the final event, a scare-simulator, Sullivan cheats by altering the sensitivity on the dummy child, to the point where slight movement will trigger the highest possible score. This makes Wazowski appear to win the scare games by delivering a record breaking score, much to the shock of everyone there. Wazowski is initially overjoyed by this, but upon discovering Sully's actions, is distraught and later breaks into the door-lab to unsuccessfully collect a human child's scream. To his heartbreak, he finds out that he is not scary. In order to get back through the deactivated door, both monsters work together to scare adults into activating the door from their side, although the doors in the room along with the canisters are destroyed in the process. These actions result in both of them getting expelled from school, although Dean Hardscrabble wishes them well after they both surprised her with the door-breaking maneuver. The two then apply as workers in the Monsters, Inc. mailroom. They advance through the ranks until Sullivan becomes a scarer, with Wazowski as his assistant.
Monsters, Inc. Mike runs Sulley's station on the scare floor and they are best friends and roommates. Mike is in a relationship with Celia Mae at this time. Additionally, Mike helps Sulley in his mission to save Boo. While Sulley bonds with Boo, Mike desperately wants her gone. Randall finds out his involvement from the glimpse of him near Boo in a newspaper and Mike makes a deal with him to return Boo. However, this makes Sulley suspicious and Mike tries to prove him wrong. Randall ends up abducting Mike for the scream extractor. At the last second, Mike is saved from the extractor by Sulley and after he and Sulley foil Randall's plot, they report Waternoose's involvement in the scheme to the CDA.
Monsters at Work Following the arrest of Waternoose, Mike and Sulley are put in charge of Monsters, Inc. He works as a Jokester and trains former scarers to be Jokesters. ==In other media==
