Bowser was born to Morton Koopa Sr. along with his brother, Wart, who was born with some deformities. When his father died, Bowser took over as king. Kamek raised him since he was very young when he became king. Bowser never listened to Kamek's instructions and never became a true villian. One day when Bowser was having a meeting with the rulers over the Mushroom Kingdom, he met Princess Peach. Bowser insantly fell in love with her. So, naturally, he asked her out. Peach refused because Bowser was "ugly". Bowser, furious that she said no, kidnapped her. Mario saved her from Bowser and knocked him into a pit of lava. Bowser survived his run in with Mario and went into hiding while Mario fought his brother. During this time he had eight children. Bowser rechallenged Mario and was decimated by Mario. Since then, Bowser has made more and more pathetic attempts at kidnapping the Princess, failing everytime.
Bowser has a very complicated and interesting personality. He is evil but only out of desperately. Bowser abducts Peach constantly, almost relentlessly. However he does this because of his love for her. He is more of an anti-hero than a true antagonist. Bowser was once a nice guy until his battles with Mario turned him into a grumpy ornrey Koopa. He is also very dumb. His common sense and book smarts are almost the lowest in the series, and thats saying something. Bowswer is illiterate as seen in Party of the Century wherehe orders Kamek to read for him. He has a very large temper, threatining to beat up, not only his minions, but his kids too.
Bowser has very few friends. Trooper is his closest thing to a friend. They went to school together and were best friend. Bowser made Trooper his second-in-command once he became king. Trooper now worships Bowser, and Bowser beats him up whenever he talks. Wario and Waluigi like Bowser too. He gives them money and Sexy Man Magazines to help him defeat the Mario Bros. He also has a good relationship with Petey. Bowser's worst enemies are the Mario Bros., constantly foiling his plots to abduct the Princess. The Princess also hates him because of how often he kidnaps her. Infact most of Bowser's enemies were made solely because of his attempts at kidnapping Peach. Toad, Yoshi, Daisy, and Toadsworth hate him for this reason.
Bowser's relationship with his family is a strange one. He loves most of his older Koopakids but hates the younger ones. He loves Ludwig, BJ, and Roy. Moderately likes Lemmy and Iggy, and hates Wendy, Larry, and Morton. Infact he states that in TDI that the three were born off drunken affairs. However he does beat all of his kids, even the ones he loves. Kamek raised him when his father died, since Bowser was still a little koopa. This makes Kamek one of his closest friends. Wart dislikes Bowser because his family loved Bowser more. Kamek refused to raise Wart, further adding to his jealousy towards his brother.
