Columbus Circle is a famous traffic circle where Eighth Avenue, Broadway, Central Park South (West 59th Street), and Central Park West intersect.
Primary Canon HistoryEdit
Upon being possessed by Vinz Clortho, Louis Tully was seen emerging from the southern part of Central Park at the Merchant's Gate. He walked past the USS Maine National Monument and mistook a horse for Zuul and tried to make contact. The Coachman asked Louis if he wanted a ride. Vinz flared his red eyes at him and ran off in a rant about how everyone will perish in flames, knocking over a woman's bag. The next night, the Stay Puft Marshmallow Man was manifested at Columbus Circle then walked up Central Park West.
Secondary Canon HistoryEdit
IDW Comic SeriesEdit
During one of his dreams, Ray Stantz witnessed the Stay Puft Marshmallow Man, with his face, march down 2 Columbus Circle. The day after Winston Zeddemore and Tiyah Zeddemore's wedding, Janine Melnitz met with Dana Barrett at the Pequod's on Columbus. Soon after they started talking, vehicles on Columbus Circle began to float in the air. Later that day, the strange phenomenon was studied by Peter Venkman, Ray Stantz and Egon Spengler. While there were conflicting readings, it was apparent a localized entity was able to make changes on the subatomic level. As the Ghostbusters' studies progressed, some vehicles came crashing back down to the ground. Columbus Circle was soon showered with Blood Rain. A few hours later, the vehicles ceased to float.
