Bowser

King Bowser Koopa, known commonly as Lord Bowser, King Koopa, or simply Bowser, is the primary antagonist of the Mario franchise and Mario's arch-enemy. Bowser usually kidnaps Princess Peach to try and marry her and rule the Mushroom Kingdom and sometimes even the galaxy. Bowser is the ruler of the Koopas. Bowser has shown a softer side and sometimes sides with Mario, but he has still remained Mario's arch-enemy. Bowser made his debut in Super Mario Bros. in 1985.
