Dark Koopa (Super Paper Mario)
From the Super Mario Wiki, the Mario encyclopedia
Dark Koopas appear in the Flopside Pit of 100 Trials in Super Paper Mario. They appear in rooms 2, 5, 9 and 72 of the Flopside Pit. In this game, they are shadowy versions of Koopa Troopas. As enemy Koopas in the Paper Mario series, they wear sunglasses, even in the dark, noted by the tattle (the Paper Mario: The Thousand-Year Door Dark Koopas' habit of wearing glasses is also noted in that game's tattle). They act as regular Koopas, but since they are silhouettes, the shell's color cannot be distinguished, which makes it unknown if the Koopa Troopa stops at the ledge or continues. They are also stronger than regular Koopas.
