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.
