"What is the magic word, Mr. Venkman?"
Maurice LaMarche
The Real Ghostbusters (1987)
Has a dangerous grudge against the Ghostbusters, especially Dr. Peter Venkman. (Ghostbusters, Big Trouble With Little Slimer)
Ordered the shutdown of the Ecto Containment Unit, which resulted in an explosion, the sign of the coming of Gozer. (Ghostbusters)
Has gone under several different nicknames (Mr. Pecker, Dickless, Pencil Neck.). (Ghostbusters)
Was so desperate to get his revenge on Ghostbusters (Venkman especially.), that even though he'd seen the Stay-Puft Marshmallow Man he still wanted NYPD officers to go up to the roof of 550 Central Park West and arrest the Paranormal Eliminators. Had a large amount of Ectoplasmic marshmallow dropped on him, sending him into a rage. (Deleted from Ghostbusters, Ghostbusters)
After being fired from the EPA after the incident concerning the Ecto Containment Unit during the Gozer incident, he eventually was hired into the BUFO, the Bureau of Unidentified Flying Organisms. He worked his way up to a high position of authority, which he used to his advantage against the Ghostbusters by attaining an order to experiment on Slimer. He was so embittered he even risked destroying the building the bureau was based in. That incident got him fired, along with his glorified chauffer and henchman known as Callaghan. Holds the Ghostbusters responsible for loosing him his job. He is cold and scheming, but not very skilled, he requires either his job, or his henchman to carry out his revenge attempts, which have so far resulted in failure. Has also resorted to calling in prank calls to GBI to arrest the Ghostbusters, however that attempt backfired somewhat when he called in a prank call at a Government installation, and a ghost was discovered to be affecting the building's centrifuge.
