Slimer is very well-meaning, but is often pushed around by the Ghostbusters as he gets in their way and eats continually. In "Fear Itself", it's revealed that Slimer is afraid of broccoli (which is ironic, as he has been shown to eat anything). However, he is given a less cartoony look to fit in with the series' overall style.
This is reflected by the use of a gritty, rock/ punk-inspired variation of Ray Parker Jr.'s song " Ghostbusters" as the opening theme, written by Jim Latham and performed by voice actor Jim Cummings. The series is styled as a supernatural comedy, following the trend set by its predecessor, but given an updated and darker feel. The series follows the adventures of this "Next Generation" of Ghostbusters tracking down and capturing ghosts all over New York and occasionally beyond the city. Filling the cast are Janine Melnitz, the Ghostbusters' previous secretary who returns to the job, and Slimer, a hungry ghost. These are Kylie Griffin, a goth girl genius and expert on the occult Eduardo Rivera, a cynical Latino slacker Garrett Miller, a young white paraplegic athlete who uses a wheelchair and Roland Jackson, a studious African-American machinery whiz.
When ghosts start to reappear, Egon is forced to recruit his lone four students as the new Ghostbusters. Egon Spengler, who still lives in the firehouse to monitor the containment unit, take care of Slimer, further his studies and teach a class on the paranormal at a local college. Each member has gone their separate way, except for Dr.
Set years after the end of The Real Ghostbusters, lack of supernatural activity has put the Ghostbusters out of business.
