Scooby-Doo 2: Monsters UnleashedIn Scooby Doo 2: Monsters Unleashed, the 10,000-Volt Ghost is a giant orange ghost that can manipulate electricity. The 10,000 Volt Ghost is much bigger than he is in the animated series and can travel through electrical circuitry. He is the third monster to be brought to life and originally was to help the Black Knight steal the rest of the costumes from the museum (shown in a deleted scene on the DVD). He attacks the gang when they are in the Monster Hive and chases them up an elevator and to the Mystery Machine. He attacks Daphne later on and defeats her easily. He then meets his end when he is sucked into a pair of jumper cables and into the Black Knight Ghost, causing him to explode. In the credits, it claims he has two voice actors: Dee Bradley Baker and Terrence Stone.
He also appears in Scooby-Doo! Unmasked.
