Ghost (Luigi's Mansion series)

The ghosts are species from Luigi's Mansion and Luigi's Mansion: Dark Moon.

History
The ghosts first appear in Luigi's Mansion. The ones in this game are created by the ghost artist Vincent Van Gore after King Boo releases him from his portrait, along with the other Portrait Ghosts.

Different types of ghosts appear in Luigi's Mansion: Dark Moon, the sequel to Luigi's Mansion, however, these ghosts are friendly and help Professor E. Gadd. However, when the Dark Moon is destroyed by King Boo, the ghosts turn against E. Gadd and go on a rampage, commanded by King Boo. Luigi once again comes up behind them and not only fixes what they break, but also catches them all, and repairs the Dark Moon, making them friendly yet again.
