Peter Venkman is one of the Fun Pack characters in LEGO Dimensions 2: The Rise of Enoch, from the Ghostbusters franchise.
Background
Peter is portrayed as the "lazy" Ghostbuster. He doesn't usually take his work seriously, has a dry sense of humour, and flirts with women, including clients such as Dana Barrett and Ilyssa Selwyn. While Peter is a scientist, he isn't as technically experienced or academically inclined as Egon and Ray, and also tends to be more aggressive when fighting ghosts.
Peter also slacks off on experiments and usually focuses on the women or other subjects, as in the first movie he is testing sixth senses and shocks the boy in the experiment for getting the answers wrong (even though he was really getting a majority of them right) and refuses to zap the pretty blonde (even though nearly all her answers were wrong). Peter is also a very outspoken person, as he back-talked to EPA representative Walter Peck and provoked him when the discussion shifted to the storage facility. This encounter led the Containment Unit being shut down and all the ghosts escaping over New York. Peter's fast-talking, however, "bargained" the percentage from the broker they consulted in mortgaging Ray's house (in order to lease the Firehouse), as well getting their first payday of $5,000 made busting Slimer. His "gift of gab" also won over the mayor's judgment against Walter Peck.
