This being lives in the Mystic Haunt. When Sonic and Tails enter, this being takes their form, and challenges them throughout the zone, before losing to the pair.
The Mimic Ghost can become an exact duplicate of Sonic or Tails, minus its glowing red eyes. In its cutscene sprite it seems to have a ghostly body including a ghost tail. However, during the act it is shown to have a complete, transparent body of the character's appearance.
The origin of the Mimic Ghost is never confirmed, as it has never been seen prior to Sonic Rivals 2 and is never seen again.
