President Koopa, also briefly referred to derisively as "King Koopa," is a former military leader under King Bowser, until he revolted and took control of Dinohattan from him. He later plotted a full-scale assault and takeover of the human dimension, which he would achieve by reuniting and merging the two dimensions into one by inserting Princess Daisy's meteorite shard back into its proper place. He is the primary antagonist of the Super Mario Bros. film.
