Gramps the Vamp appears in "Vampire Bats and Scaredy Cats", an episode of The Scooby-Doo Show. He was the disguise of Leon, the uncle of hotel heiress Lisa Vanhoff.
Powers and abilities
As the vampire, Leon used a special whistle to control his vampire bats, which he bought at an exotic pet shop. Velma Dinkley realized this when Scooby-Doo and Scooby-Dum could hear it and she couldn't. Leon also used a watch to hypnotize Lisa into thinking she was a vampire and attacking Shaggy Rogers and Scooby-Doo.
Uncle Leon claimed to Lisa that the vampire in question was her late grandfather. It supposedly took control of her in order to haunt Great Skull Island. When the vampire was defeated, it was discovered to be Uncle Leon in disguise, in a plot to keep his niece from claiming the hotel.
- In the Norwegian dub, the vampire is called Per Skjølsvik.
