Bowser

Bowser is the evil king of the turtle-like Koopa race. He is constantly trying to kidnap Princess Peach, although he is always foiled by Mario and his friends. However, in a few installments he teams up with his arch-nemesis to take on an even greater villain, such as Count Bleck. In Super Paper Mario, Count Bleck forced him and Peach to marry (Bowser wanted to). However, since Count Bleck is probably not authorized to perform that sort of thing, it is probably not legal. Peach considers it a sham but Bowser thinks it was real and still considers her his wife throughout the game. He rules over the Koopa Kingdom and the Koopa Troop is his army.
