Ghosts are ghostly enemies from the game Find Mii.
Ghosts appear as enemies in Smash Run. Only Yellow ghosts appear, and they carry a shield which serves as a perfect shield which can also deflect projectiles. The ghost also has excellent pivoting which will make it harder to hit them. The best way to kill them is by grabbing them, as Perfect Shields do not protect the user from grabs.
Ghosts that appear in the Find Mii game in StreetPass Mii Plaza. In Smash Bros., these ghosts have their own shields to ward off attacks. They try to keep their distance, but that doesn't mean you can ignore them--they'll often use their shields to protect other enemies. Hit from behind to defeat these pests.
