Who Is Mike Wazowski?
Mike Wazowski is a monster who lives in the city of Monstropolis. His full name is Michael Wazowski. He is green and round, with a single large eye, two arms, two legs and two tiny horns. He is short, but he has a big personality.
In the first film, Mike works at a company called Monsters, Inc. This company collects screams from human children to make power for the monster city. Mike is the scare assistant of his best friend, James P. Sullivan, who is known as Sulley. The two are also flatmates.
What is he like?
Mike is charming and organised. He likes to plan, and he likes things done the right way. He also has a big ego, and it sometimes gets him into trouble. He is funny, loyal and quick to panic, and that mix makes him easy to love.
His girlfriend in the first film is Celia Mae, who is voiced by Jennifer Tilly.
Who Voices Mike Wazowski?
The actor Billy Crystal gives Mike his voice. He has done this in the films, in the short films and in the Disney+ series Monsters at Work. Crystal is also known for live action comedies and for hosting the Academy Awards.
Here is a fun fact about the casting. According to Wikipedia, Crystal turned down the role of Buzz Lightyear in Toy Story. Later, he said that he regretted it. When the chance came to play Mike, he took it. Tom Hanks and Tim Allen did the Toy Story roles, and Crystal found his own famous voice part.
Monsters, Inc. (2001)
Mike first appeared in Monsters, Inc., a Pixar film made for Walt Disney Pictures. The director was Pete Docter. It had its premiere on 28 October 2001, and it was released across the United States on 2 November 2001.
The main voices
- Mike Wazowski: Billy Crystal
- Sulley: John Goodman
- Boo: Mary Gibbs
- Randall Boggs: Steve Buscemi
- Mr Waternoose: James Coburn
- Celia Mae: Jennifer Tilly
- Roz: Bob Peterson
The story in short
Monsters believe that human children are toxic. But the city needs their screams as energy. One night, a small girl named Boo slips into the monster world. Sulley and Mike try to send her home, and they uncover a plot by Randall, a rival, and by their boss Waternoose.
Along the way, they learn something important. Laughter, they find out, is much stronger than screams. At the end of the film, Sulley becomes the head of the company, and Mike becomes the top comedian at the new Laugh Floor. It is a gentle ending, and the film is made for the whole family.
How Mike Was Created
The idea for Mike came late in the planning. Pete Docter began work on the film in 1996. Its working name was “Hidden City”. Mike was added to the story at a meeting in Burbank on 6 April 1998. The artist Ricky Nierva made the first sketch.
The name has a nice story. Mike is named after Mike Oznowicz, who is the father of the puppeteer Frank Oz. Frank Oz is a famed voice actor who also worked on the film. Early drafts of Mike did not give him any arms. The final design has two arms.
Awards and Praise
The film was a success. In the first year of the Oscars’ Best Animated Feature award, it was nominated, but the prize went to Shrek. Yet the song “If I Didn’t Have You” by Randy Newman won the Oscar for Best Original Song. The film’s budget was about 115 million dollars.
Mike After the First Film
Mike’s New Car (2002)
This is a short comedy film. Mike buys a new car and has trouble with it. It appears on the home video releases of the first film.
Finding Nemo (2003)
Mike also makes a small cameo in the end credits of Finding Nemo. It is a fun sight for sharp eyed viewers.
Monsters University (2013)
This film is a prequel. It was released on 21 June 2013 and was directed by Dan Scanlon. It shows Mike and Sulley when they were young students. At first, they are rivals. Mike joins a team called Oozma Kappa to enter a contest called the Scare Games. The team faces the strict Dean Hardscrabble. At the end, both Mike and Sulley are expelled from the university and begin work in the mailroom of Monsters, Inc. That is how their friendship and their career start.
Monsters at Work (2021)
This Disney+ series started on 7 July 2021. It begins on the day after the arrest of Waternoose. Now the company must use laughter for power, so Mike works as a “Jokester”. A new character, Tylor Tuskmon, voiced by Ben Feldman, joins the story as a young monster who dreams of being a Jokester too.

A third film
According to Wikipedia, which cites Variety and the Wall Street Journal, a third Monsters film was announced as in development in March 2026. No release date was given in the sources that I read, so I will not guess one.
Mike in Pop Culture
Mike is a popular figure online. The face swap picture of Mike with Sulley’s face, which was written about by Time in 2019, spread far and wide. Another popular meme shows Mike as a character who is explaining things.
Critics like him too. Rolling Stone ranked him the eighth best Pixar character in a 2020 list. Screen Rant placed him seventh in a list in 2015. Such lists are matters of opinion, but they show how well the character is liked.
Theme park rides
Mike and Sulley appear at Disney parks. A ride called Mike and Sulley to the Rescue opened in 2006 at Disney California Adventure. Monsters, Inc. Laugh Floor opened in 2007 at the Magic Kingdom. A ride called Ride and Go Seek opened in 2009 at Tokyo Disneyland.
Tips for Watching the Films in Order
If you are new to the series, you can watch in two ways. The first way is by release date. Start with Monsters, Inc. in 2001, then watch Monsters University from 2013, then the series Monsters at Work from 2021. This way you see the story as the world saw it.
The second way is by story time. In that case, start with Monsters University, since it is a prequel. Then watch the first film, and finish with the series, which begins the day after the first film ends. Both ways work well. Young children may enjoy the first film best, since it has a clear and simple plot.
Why Children Love Mike
Mike teaches a few simple lessons. First, he shows that it is fine to be small. His size never stops him from trying. Second, he is a loyal friend. He stands with Sulley in hard times. Third, he learns that his own ego can hurt others. That change makes him grow as a character.
The films also teach that laughter is a kind of power. A joke can make a room warm, and a shared laugh builds bonds. That is a lesson that children and adults can both enjoy.
