Possessed is an Inverted Impulse launched roller coaster located at Dorney Park & Wildwater Kingdom in Allentown, Pennsylvania. Manufactured by Intamin and designed by Werner Stengel, the roller coaster originally debuted at Geauga Lake amusement park as Superman: Ultimate Escape on May 5, 2000. After Cedar Fair purchased Geauga Lake in early 2004, the coaster was immediately renamed Steel Venom. The ride closed in 2006 and was moved to Dorney Park. It reopened in 2008 briefly under the name Voodoo, and was renamed Possessed for the 2009 season. The model is identical to five other impulse coaster installations at other amusement parks, and a larger version called Wicked Twister is located at Cedar Point.
