Dr. Ghastley is a counterfeiter.
Scooby-Doo's Haunted Mansion
He was illegally printing money in the dungeon in Ghastley Manor and he dressed up as the Phantom Shadow to scare away any trespassers. He never made it to jail as a skeleton was driving the police van with the real cop tied up in a box.
- An early hint that he is the villain is in the portrait hall where his portrait turns into the Phantom Shadow.
