Michael first appeared in a robbery mission in North Yankee Town at the beginning of the game. He is one of the protagonists of the game and can be said to be the most important person. Most of the storylines of the game are started by Michael. Michael used to be a professional robber, but in the robbery mission in North Yankee town, Michael made a deal with FIB in advance, and then he quit. At the same time, he participated in FIB's witness protection program (in fact, he helped FIB do something they couldn't do), and he was closely related to FIB's agent Dave Norton (in essence, they used each other). In my opinion, Michael is a tragic figure. In the eyes of others, his life is full of inexhaustible wealth. Even Franklin said when he first came to Lao Mai's house: Oh, my God, man! You have a good time here. (God, you have a good life) But no one knows that Mai has been suffering. Because of family conflicts, Mike can only drink at home alone. In fact, he wants to be a good father. He loves his family. In the game, you can find that Michael has saved his family more than once.

Michael's wife Amanda, her husband and son Jimmy, her daughter Tracy and her father have a very bad relationship, and the family is on the verge of collapse. Amanda is dissatisfied with Michael's maverick style and thinks that he doesn't care enough about Michael himself. She suspects that Michael is fooling around with prostitutes outside (this is true), and her daughter and son don't like his father (only love his money) because they haven't communicated with him for a long time. Michael once went to see a psychiatrist because of his psychological problems, but the damn psychiatrist cheated him! Michael knows that he is living in a dream. As he said, he is immersed in a movie he imagined in1980s. He loves his family, but in the wrong way. No one in the family understands that everything he does is actually a sign of loving his family.

In the game, Michael is very suspicious, and everything is centered on the interests of himself and his family, which is also related to Michael's own experience, but he is also the most rational, calm and rational of the three protagonists, and all criminal action plans are decided by Michael. He has good endurance, especially good at using firearms for accurate shooting, and his stealth ability is also the best. His special ability is bullet time. It can make him slow down everything around him when he walks, but he is not affected. In the mission, Michael usually plays the role of sniper and diver.
