Bowser, sometimes known as King Koopa or King Bowser, is a large, powerful, fire-breathing Koopa who leads a large army of minions and is been the arch-nemesis of Mario. His personality is cheeky and scheming, and he has anger problems. However, he's very smart, and is a powerful leader, but is a good loser. He's hopelessly devoted to the one he loves, but misses some important events because of his status as king Koopa. He has red hair, bushy eyebrows and spiked collars on his arms and neck.
