Voiced by Billy Crystal, Mike is one of the main characters of Monsters, Inc. (2003) and its prequel Monsters University (2013). Mike is the one-eyed green monster and the best friend of the top scarer, Sulley. Together, the two work at Monsters, Inc where they harness the screams of human children for energy. But a spanner is thrown into the works when Mike and Sully accidentally bring Boo, a human child, into the monster world. In Monsters University, we see how Mike met Sully and how they became the best friends we know and love. Ever the lovable monster, Mike is funny, sarcastic and a smooth talker, especially with his girlfriend Celia.
