About

Egon Spengler is a tall, laconic, bespectacled, awkward member of the team responsible for the main theoretical framework for their paranormal/geological studies. Being addicted to science, he is the creator of the Ghostbusters' equipment along with Raymond Stantz, thus making him the brains of the Ghostbusters.

Spengler's role was the equivalent of Velma Dinkley in the Scooby Doo cartoons; if the other members of the team didn't understand something about their current situation, they'd ask him to explain, although they often wouldn't understand the answer he gave. Although he was brilliant, Spengler didn't have much social ability (as demonstrated in his interactions with the Ghostbusters' secretary Janine Melnitz), and generally needed Peter to do the talking for the group.

Spengler is the most serious and straight-forward member of the team. Of his hobbies, he states that he collects "spores, molds, and fungus", and claims that, as a child, the only toy he ever had was "part of a Slinky", which he straightened. As implied in the first movie, Spengler apparently is a sugar junkie, due to his affection for sweets and candy (such as Twinkies and Nestle Crunch bars). He also once attempted self-trepanation, but was stopped by Peter Venkman. As Venkman told Spengler "This reminds me of the time you tried to drill a hole in your head," to which Spengler replied, "That would have worked if you hadn't've stopped me."
