Ghostbusters International: Spooked in Sacramento
Warden Jack Holmes
Known in his life as a particularly harsh overseer, for Jack Holmes death changed little. He was discovered by the SGBs driving a horde of entities to capture and keep prisoners in an abandoned penitentiary in the Roseville area. He had the ability to conjure lesser spirits in order to do his bidding. His power seemed to be linking to his ability to hold living prisoners. With five or more human captives he appeared impervious to the application of proton packs. However, once all of his corporeal prisoners were released he was able to be captured by the SGBs after a fierce battle.
