Zuul". Peter gives Zuul to the count of three to leave Dana's body, to which she responds by turning her eyes white, thrashing her head back and forth on her bed, then growling furiously like a beast, and levitating above her bed. Peter, realizing the seriousness of Dana's condition, sedates her and calls Egon to explain what is going on. He soon learns from Egon that her building was renovated by an evil architect named Ivo Shandor, and she is possessed by Zuul, the Gatekeeper of Gozer. After Peck returns and shut down the Containment Unit, the ghosts all escape, and Peter and the other Ghostbusters are imprisoned for EPA violations. Peter convinces the mayor that an apocalypse of "Biblical proportions," is coming to destroy the city. The Ghostbusters are released and go toward Dana's building, escorted there by a police and army motorcade as a dark cloud starts to cover the entire city. After an earthquake strikes, nearly trapping them in rubble, the Ghostbusters made it to the top of the building. However they are too late to stop Dana and Louis Tully from releasing the evil Gozer and transforming into their possessors' Terror Dog forms. The Ghostbusters confronted Gozer, who electrocutes them before being zapped by their proton packs. He vanishes and returns in the form of the Stay Puft Marshmallow Man (which Ray had been thinking of). Peter and his team then cross their proton streams, and force the door to Gozer's dimension to close, destroying the Marshmallow Man in a blaze of flames and saving the city. Peter rescues Dana, no longer possessed, from the rubble of Zuul's charred body, finally winning her affections for saving her. Ghostbusters II (1989) Despite saving the town from Gozer, the Ghostbusters were put out of business due to being sued for all the damage that was done during the battle. Also, Peter and Dana's relationship faltered due to his fear of commitment and taking her for granted. She left for her male colleague in the orchestra, married him and had a child. He unexpectedly "ditched" her for an opportunity leaving her and his son behind. In the years since, Egon described Peter (even to Dana) as being borderline(-manic) until he eventually "crossed the border." Peter became the host of a psychic reality talk show in the years after the Gozer battle. He and his teammates went to Dana's aid
