Bowser is a big, fire-breathing, meat-eating koopa with a spiked shell, horns, and sharp teeth. Known for his intimidating roar and power-hungry nature, he repeatedly tries to kidnap Princess Peach and marry her to rule the Mushroom Kingdom. While generally sinister, he has a more comical side as a blustering buffoonish bully with emotional vulnerability, evident by his poor planning. He's narcissistic, greedy, brash, scornful, and anger-fueled. Though harsh, he does return his minions' loyalty.
