Mike was born in Sacramento, California. He is the only child in his family.
His family moved to Forks when he was 10 years old and opened Newton's Olympic Outfitters. During high school, Mike started working for his parents, selling camping and hiking gear. He became a popular kid in school and dated some of the most popular girls, including Lauren Mallory, and later Jessica Stanley, who already had a crush on him.

Edward and Mike are always at odds for Bella's attention.

At the beginning of New Moon, Bella states that Mike seemed to have gotten over sulking and has finally accepted that they can only ever be friends. When Bella goes into her 'zombie period', Mike asks her every Friday if she will go to work the next day, and stops walking her to classes. Bella tries to rekindle their friendship after four months of 'being a zombie' after the Cullens leave Forks. Mike becomes her friend again, although not with the same enthusiasm, and never forgets his fondness of her. After an action movie outing (Crosshairs) with Bella and Jacob, which ended up with Mike vomiting from the bloody scenes, he seems to have given up on her, and tells her that "girls are cruel". However, Mike is one of those who willingly accept her back after her depression.
In the movie adaptation of New Moon, Mike is the one who asks Bella out to watch a movie, and the action movie they watch is called Face Punch. Jacob threatens to put him in the hospital after he interrupted his conversation with Bella.

Mike becomes somewhat of a minor character in Eclipse, being only someone Bella sees at school and work, and as a guest at the Cullens' graduation party. During Calculus class, he gossips with Tyler, Ben, and Austin about the possibilities of Jacob and Edward fighting, and Mike is determined that Jacob has the best chance of winning.
After graduation, he starts working full-time at his parents' shop.
In the Eclipse film, Mike offers Jessica an old-fashioned speech for graduation, but she rejects his offer and throws the speech right into his head. He is last seen sitting behind Bella at the graduation ceremony, listening to Jessica's own speech and cheering on her behalf.

- "What a gene pool."
Mike makes his final appearance in the Twilight series at the beginning of Breaking Dawn, where he attends Bella and Edward's wedding with Jessica as his date. Edward says that Mike has inappropriate thoughts about Bella at the wedding, despite them swearing their vows, but is too happy and infatuated with Bella's dress to give in to anger.
In Breaking Dawn - Part 1, he attends Bella and Edward's wedding. While there, he notices the Denali family and suspects that they are related to the Cullens. He is last seen waving goodbye to the newly wedded couple. This marks the last of his appearances in the Twilight Saga.
Mike is described as having pale blue eyes, blond hair, a baby face, being 5'11" tall and being altogether good-looking. Mike is very popular in Forks High School.
He had a baby face in Twilight, but it matures slightly in the later books. Initially, he wore his hair in spikes, but then decided to grow it out and also starts using hair gel in attempt to mimic Edward's look.
Bella describes Mike as a golden retriever: loyal, and obsessively following random people. Edward hates Mike because he is attracted to Bella, with inappropriate thoughts about her. Mike is athletic and very friendly to those he likes, but also obnoxious, persistent and competitive, and is dense on sensing other people's signals while he infatuates Bella. He also has a weak stomach, the sight of blood and action movies make him feel uneasy to the point that he vomits. For this reason, he has a dislike to action movies.
In Midnight Sun, he has hateful, jealous thoughts regarding Edward's relationship to Bella, which Edward finds very disturbing and comments he could kill him just to shut him up. He also tends to think badly of the Cullens because of their perfection, such as beauty and wealth. He goes so far to even think "I wish Cullen would drive his nice, shiny car off a cliff." Other than the Cullens, he also dislikes Jacob Black and any other guy who speaks to Bella, though not as intense.
Mike is the only child in his family.
- Main article: Bella Swan
Bella Swan is Mike's classmate. Mike is infatuated with Bella as soon as she starts going to Forks High School. He seems to only like Bella because of her popularity and good looks, and she does not reciprocate his feelings. He asks her to the spring dance, but she turns him down just like she does with every other person who asks her. Edward shows a dislike for Mike over his possessive and lecherous thoughts about her. Mike later becomes very jealous when he realizes that Bella is in love with Edward, who he considers a freak. In Midnight Sun Edward does mention that he became jealous of Mike when he asked Bella to the dance.
It would seem that Mike never completely got over his feelings for Bella. Edward commented that Mike was having improper thoughts about Bella while attending their wedding in Breaking Dawn.
Jessica Stanley is Mike's on and off girlfriend. They went out briefly in their sophomore year. In their junior year, Mike only goes out with Jessica at Bella's urging, because she knows that Jessica has a crush on him.
Their relationship does not last very long, and they break up that same summer. However, Bella notes that at her wedding, Mike and Jessica were holding hands. She is surprised and pleased to discover they are back together.
