Peter Venkman, while not the leader of the Ghostbusters, is the most iconic one. He's a scientist and former college professor who took up Ghostbusting after Raymond Stantz created the Ghostbusters. Peter Venkman seems less to care about the ghostbusting aspect and more about the money and getting rich off high prices, he's generally lazy and doesn't take the job seriously. He's very outspoken and persuasive, and prone to acting brash if angered, he's also a serial flirt with women.
