Michael "Mike" Wazowski is the deuteragonist of Monsters, Inc. and the protagonist of its prequel Monsters University. He is a light green, spherical monster with one large green eye, two small horns on his head, and thin arms and legs attached to either side of his torso.
In the first film, Mike is Sulley's best friend and working partner at Monsters, Inc.. He supports Sulley about being the number one scarer, and both are enemies of Randall Boggs. He is also Celia Mae's boyfriend and seems to be watched at by Roz who awaits for his paperwork. While at Harryhausen's for Celia's birthday, Sulley appeared out of nowhere to tell Mike that he had lead a human girl into the monster world. Putting her into a Monsters, Inc. gym bag, Sulley tried to show him, but the human girl got out of the bag and wreaked havoc all over the restaurant. The two secretly took her out before the CDA found her and disinfected the entire restaurant.
When they learn that Randall and Waternoose are in on a scam of draining children of screams, Sulley tricks Mr. Waternoose into confessing Randall's plan and him working as Randall's henchman while Mike records the confession and smugly replays it to watching CDA agents. Immediately, the CDA turn on Mr. Waternoose and arrest him for being in cahoots with Randall. Once Boo is back in her room, Mike rebuilds her door that the CDA destroyed so Sulley will be happy again.
Sometime after the film, Mike's low-budget company play "Put That Thing Back Where It Came From or So Help Me" that he has starred in, written, directed, and produced comes in front of the audiences.
Mike's New Car
In the short, Mike is now the protagonist of his own story. He has brought a new six-wheel drive car, and wants to show it to Sulley. When they both get in the car, Sulley accidentally ruins the brand-new car and injures Mike. In the end, Mike kicks Sulley out, speeds off and wrecks the car completely.
Monsters UniversityMike reappeared in the prequel as the protagonist. He looks smaller and wears a retainer.
Mike Wazowski is first seen as an elementary student attending Ms. Graves' class visiting Monsters, Inc. as part of a field trip. During the field trip, Mike tries to get a look at the scare floor but the other students push him aside, telling him he doesn't belong there. Mike walks past the safety line and follows a scarer named Frightening Frank McCay into the Human World. Mike watches Frank scare a child then follows him back through the door. Frank is not only surprised but impressed with Mike for sneaking in unnoticed, giving him his Monsters University cap. This incident spurs Mike to become a scarer and attend MU.
On the first day at college, a now 17-year-old Mike's roommate is revealed to be Randall Boggs (his and Sulley's eventual archenemy) who is friendly towards Mike. When he sees Randall's invisibility at work, Mike encourages him to use it more, telling him to lose his glasses which don't turn invisible. While attending Scaring 101 at Professor Knight's class Mike sees a student named James P. Sullivan, who despite his natural talent is lazy and arrogant. Dean Hardscrabble, the school's headmistress and a famous Scarer then flies into Prof. Knight's classroom and tells all of the students that they all had to complete a final exam at the end of the semester which will determine if they stay in the program. Mike immediately commits to studying hard. Sulley then comes in through the window having stolen Archie the Scare Pig (rival school Fear Tech's mascot). Archie steals Mike's hat and runs off. Mike catches him but Sulley gets the credit for it, impressing the Roar Omega Roar president Johnny Worthington III and sparking a rivalry between Mike and Sulley. Finally, the two monsters get into an argument and they accidentally knock over Hardscrabble's scare can. Though she is calm about it, she uses the incident to fail Mike, telling him he's not scary. Sulley is also washed out of the program due to his arrogance.
Mike decides to participate in the university's Scare Games by teaming up with a fraternity made up of rejected monsters called Oozma Kappa composing of Don Carlton, Terri and Terry, Art, and Squishy. Sensing an opportunity, Mike baits Hardscrabble into accepting a wager: if OK wins, she allows the fraternity into the Scare Program; but if they lose, Mike has to leave MU. Sulley joins the team, which Mike has to accept since they need six 'bodies' and Randall has joined ROR, abandoning Mike. OK only makes it through the Toxicity Challenge because Jaws Theta Chi was disqualified. Mike then takes charge of the team and instructs them to do as he does. For the next challenge, they have to get through the library without getting the librarian's attention, retrieve their flag, and escape. Sulley's impatience nearly costs them, but the rest of OK pull it off, advancing to the next round. That same night, they are invited to the ROR house but get badly humiliated. OK is ready to call it quits, so Mike takes them to Monsters Inc, showing them that they can still become Scarers. This also sparks a change in both Sulley and Mike, and they begin to understand each other.
OK trains even harder under Mike's new leadership skills, making it through the next two rounds using their actual talent. OK is pitted against ROR for the final round, in which both teams try to out-scare the other using simulators set to their highest level. On Sulley's suggestion, Mike goes last, pitting him against Johnny. In the simulator, Mike remembers all the scorn and derision towards him in his life, unleashing his frustration in one mighty scare, and with that OK wins the Scare Games to everyone's surprise. Mike later discovers that the simulator was tampered with so that Mike would get the highest score. Sulley admits it was him, revealing his lack of confidence in his friend. Mike decides to go into the human world where he tries to scare a little girl but he finds himself in a summer camp. The other girls don't find him scary, forcing him to run. Minutes later, Sulley arrives to rescue Mike and has to escape from forest rangers who mistake him for a bear. He finds Mike at a lake, sulking over his failure. The two argue, the both of them venting their frustrations. They make their way back to the door but Hardscrabble has deactivated it. With the rangers nearby, Mike believes that they can generate enough energy to activate the door from their side. Using Mike's knowledge of scare tactics, Sulley scares the adults, which not only activates the door but overloads every scream canister in the room. Mike and Sulley make it back, but are expelled for their actions.
The two say their goodbyes to their OK brothers, who tell them that Hardscrabble was impressed with their performance in the games and allowed them into the Scare Program. For the first time, Mike doesn't have a plan, yet he states that he's "okay just being okay." Mike gets on a bus to leave MU but Sulley stops him, telling him not to settle for being okay, stating that everything that led to OK joining the Scare Program was due to Mike's efforts. Hardscrabble arrives with the school paper, showing them they made the front page. She tells them that they surprised her, something she believed was impossible. While she can't do anything about their expulsion (despite the fact she's the one who expelled them), she wishes them both luck and tells Mike to "keep surprising people."
Sulley points out an ad in the paper from Monsters Inc, giving them a chance to work at a Scare company. They start in the mailroom, then get promoted to janitors, kitchen assistants, and then can wranglers. Finally, Sulley enters the company's open tryouts, becoming a scarer with Mike as his assistant. He and Sulley became rookie of the year.
In the short film Party Central Mike shows up at Oozma Kaapa's party when Sully and Mike decides to visit them. Mike then uses a borrowed door to get monsters from the Roar Omega Roar party to show up at the party at Oozma Kaapa . When the party is over, Mike is last seen leaving the house.
Mike and Sulley argue and/or fight sometimes; however, it is usually Sulley who annoys Mike first. He is funny, smart, brave, but can sometimes fail to see the obvious in a situation. He has a very strategic mind and is a thinker by nature, arriving at conclusions very fast. He is also kind and has very smooth conversations with his girlfriend, Celia. Additionally, he is sarcastic and charismatic.
Mike is also skilled with words; he has been shown multiple times to come up with witty comebacks to Randall and anyone who gets on his nerves, but can falter if asked a question under pressure.
Mike is also shown to have a positive outlook in situations that seem disappointing by not acting disappointed but rather happy it happened. This is especially noble when an image of him is covered in some form of media, such as television, magazine covers, and school I.D. cards. An example of this is when he saw that his picture on a magazine cover was blocked by a barcode, his reaction seemed sad at first, but he turned out to be happy he appeared in the cover regardless.
Unlike Sulley, who needed some adjustment in his personality, Mike didn't change much from his MU days, aside from a boost in his ego. Being insecure and accepting to just being "OK", thanks to Sulley, Mike realized that he also has his good qualities.
- Mike was listed #23 in Empire Magazine's The 50 Best Animated Movie Characters.
- In an early animation test, Mike was considered to have no arms and would have picked things up with his feet. He would have also worn a cowboy/texan hat.

- Mike is renamed "Robert 'Bob' Razowski" in the French dub.
- Mike has a brief cameo, swimming past in scuba gear during the credits of Finding Nemo, returning the favor, so to speak, after there is a Nemo cameo near the end of Monsters, Inc. The "gear" he is wearing was what he wore to "protect" himself from Boo in Monsters, Inc.
- Mike appears in the end credits of Cars as a small car. This car version of him also appears briefly in Tokyo Mater with Sulley when Mater drives through a building.

- Whenever Mike Wazowski is shown on public media, such as a Monsters, Inc. commercial or a magazine cover, his face is actually always covered up by the text on said media (such as the Monsters, Inc. "M eyeball" logo in the commercial and a barcode on the magazine cover). Also, the DVD (and possibly the upcoming Blu-ray disc) for the film appears to take this even further by having the DVD artwork and the hole in the middle of the DVD used to secure it into place once inside the DVD player both positioned in a way so that the hole is actually placed over Mike's face!
- A similar thing occurred during Monsters University in which Mike's ID card has his head out of view.
- The gag of his face being blocked out occurs throughout the two movies, and a running joke is that he is completely oblivious to his face being obscured.
- In Monsters University, Mike is 17, meaning that in Monsters, Inc. he is about 27.
- As pointed out by Dean Hardscrabble, Mike Wazowski can never become a scarer, so in the original film he ultimately becomes a comedian instead.
