Not to be confused with KP Koopa.
KP Paratroopas are KP Koopas with wings. If jumped upon, or if a quake attack is used, they lose their wings, and become regular KP Koopas.
KP Paratroopas are extremely rare. There is only one in Paper Mario: The Thousand-Year Door. It is found in the Glitz Pit. They are not stronger in any way than a regular Koopa Troopa.
