Scooby-Doo! Night of 100 Frights

He brought back various monsters that Mystery Inc. had unmasked in the past, including the Headless Specter and the Phantom Shadow through the use of holograms. However, he was beaten by Scooby-Doo.

He got sucked up by a giant pipe and was taken back to the mansion, where Fred unmasked him to be Alexander Graham, however it turned out that Holly herself was really the Mastermind, she was able to switch places with her own uncle by putting him in one of the spare costumes so they'd think that he was the Mastermind, and she would have the whole mansion to herself.
