The koopa are led by the infamous Koopa King Bowser, the largest and most powerful Koopa in existence. They serve him out of fear, not respect, and they are always asking for a pay raise. Koopas are known for being great weapons when used properly. "All you must do, is jump on the koopa, and jump on the koopa! Then you kill koopas!" said Mario, koopa expert. Koopas are in use in the North and East Hyrulain armies.
