Mike was accepted to attend the scare program at Monsters University when he was approximately twenty. Mike's roommate was Randall Boggs, and accordingly both became the best of friends. Mike initially met James P. Sullivan ("Sully") in his SCARE 101 class. Mike did not have a great first impression of Sully due to Sully's negligence towards working in the classroom. After being conflicting and disruptive, Mike and Sully were suspended and expelled out of the scaring program. Thus, Mike makes a deal with Dean Hardscrabble: if his team were to win the Scare Games, Mike and his team members were allowed to attend the university again. Against Mike's will, Sully joins Mike's group for the Scare Games.
In pursuit to participate in the Games, Sully and Mike pledge the Oozma Kappa fraternity at Monsters University. While participating in the Scare Games, Mike and Sully become great friends and colleagues. Sadly, due to cheating in the Games, the two are suspended and kicked out of Monsters University.
