The Frankenstein Monster was a dead body put together by different body parts and re-animated with electricity by a scientist named Dr. Victor Von Frankenstein. However, it seems this is the ghost form of the monster or a ghost that has chosen to assume the form of the monster.
The Frankenstein monster had two brief appearances during spectral activity led by Proteus. He first appears in a library, in a ghostly state, which differs from the original monster who was a solid manifestation along with ghosts of Mr. Hyde and Captain Ahab. He is later seen inside the Containment Unit trying to attack Slimer.
