Dark Koopa

Dark Koopas are strong, purple-shelled Koopa Troopas that live in dark places underground. They appear in the first two games of the Paper Mario series.

Paper Mario
Dark Koopas debut in Paper Mario, appearing solely in Toad Town Tunnels like the Gloomba family. They attack using stronger versions of normal Koopa Troopas' attacks. Additionally, sometimes while idling they will grin, jog in place, and occasionally spin around, signaling that they are preparing a special attack that can make Mario dizzy. They sometimes perform this for multiple consecutive turns, thus leaving Mario stuck and requiring his partner to attack. Like normal Koopa Troopas, they are rendered temporarily helpless if knocked onto their backs.

Paper Mario: The Thousand-Year Door
Dark Koopas reappear in the Pit of 100 Trials in Paper Mario: The Thousand-Year Door, appearing in floors 31-39. They are even stronger than before, but can no longer use their dizziness-causing attack. In Super Paper Mario, this role is given to a pitch-black, shadowy Koopa also called Dark Koopa, which appears in the Flopside Pit of 100 Trials.
