Shady Koopa

Shady Koopas are enemies that appeared in Paper Mario: The Thousand-Year Door.

These guys are real shady characters, having a very secret and dangerous attack. These guys, but only when their on their shells, can activate a very powerful attack that damages both Mario and his active partner. This enemy, as stated, can only use this when he's on his shell so Mario shouldn't use just any jump attacks on this one. Mario mush fight some of these guys while participating in the Glitz Pit. More can be found in the Pit of 100 Trials.
