Koopa General is the leader of Bowser's army in Koopa Kingdom. During the assault on the Snow Kingdom, he restrained the Penguin King while the army defeated the Snow Kingdom army and Bowser reclaimed the Star.Later he informed Bowser of how the Kongs intend to surprise them by taking a shortcut through the Rainbow Road and later guiding the counter-offensive by riding a giant bulldozer with maws towards Mario. After Mario and Donkey Kong blew his vehicle up, he emerged unharmed from the explosion. Enraged, he retracted in his shell and flies at the two, mimicking a Blue Spiny Shell, successfully exploding on them, destroying the track and causing them to plummet into the sea.
