Ghost (Sandy Duncan's Jekyll and Hyde)

The ghost was the first of the many disguises of Zalia Z. Fairchild, an actor who had been secretly living at Mammoth Studios for years and was sabotaging the production of a movie because he didn't want the studio to be torn down.

Physical appearance
The ghost's body and clothes were pale white. His eyes and mouth were just black holes.

Personality
Compared to Fairchild's other disguises, the ghost was more sneaky and secretive; his other characters tended to be more aggressive in their efforts to scare the gang away.

Season one
When the gang arrived at Mammoth Studios, the ghost jumped out in front of the Mystery Machine, causing Fred Jones to swerve and get the van stuck hanging off of a bridge.

He later hid behind a hedge and tried to make a lamppost fall on Sandy Duncan while she was acting for a scene, but Scooby-Doo rescued her. However, the ghost got away, and Scooby was the only one who saw him.
