Dr. Peter VenkmanEdit
Dr. Peter Venkman (voiced by Lorenzo Music seasons 1-2 and Dave Coulier seasons 3-7) is the group's first-among-equals. While not their official leader, Venkman often makes the decision whether or not they will take a case. He also provides comic relief and is usually nominated for tasks no one else wants to do.
Dr. Egon SpenglerEdit
Dr. Egon Spengler (voiced by Maurice LaMarche) a scientific genius, is the primary source of expertise the group uses to understand (and many times combat) the ethereal realm. A skilled theorist, in many episodes Egon formulates the solution when all hope seems lost.
Dr. Ray StantzEdit
Dr. Ray Stantz (voiced by Frank Welker) is portrayed as an excitable jack-of-all-trades. He is second only to Egon in sheer intelligence, and leans towards practical applications of science as opposed to Egon's pure research – the engineer to Egon's physicist. He is also a child at heart, cheerful and optimistic (and rather enamored of cartoons and stuffed animals). As the only one of the four who can reliably understand what Egon is talking about, he is usually the one to put his theories into practice.
Winston Zeddemore (voiced by Arsenio Hall seasons 1-3 and Buster Jones seasons 4-7) is the courage and straight-man of the group; his accuracy with the proton gun is his forte. Of all the Ghostbusters, Winston Zeddemore has the most subtle character development; it is hinted that he is an avid reader and the descendant of a powerful African bloodline. Sometimes his last name is misspelled "Zeddmore"
Slimer (voiced by Frank Welker) is the pet of the Ghostbusters and is the only ghost that will stay still for Egon to test and study. Out of all the four Ghostbusters, Peter is the only Ghostbuster who gets angry and yells at Slimer easily. In the kenner toy line known also as the "Green Ghost".
