Slug is the paternal entity in a trio of ghosts. They appear to originate from New Jersey, according to the P.K.E. Meter readings taken while they haunted a Conrad's chocolate plant. The Ghostbusters eventually captured them after a lengthy bust, but they escaped from the Containment Unit. Slug desired revenge and set up a fake paranormal eliminations and investigation business to bankrupt the Ghostbusters.
As his scheme began to pay off, Slug decided to escalate things and seek out an old friend named Turlock. They arrived at an abandoned toy factory in Brooklyn, a known dwelling of Turlock. Instead, Slug awoke and angered a Free Roaming Vapor that turned out to be a Full Magnitude Class 10. It pursued Slug and his family across the Brooklyn Bridge. The Ghostbusters recaptured them and then focused on the Class 10. Slug and the family were later part of the entities that witnessed the arrival of Egon Spengler into the Containment Unit universe when he was in search of the Ghost of Christmas Future, Ghost of Christmas Past, and Ghost of Christmas Present.
