Hydra the Revenge, or simply Hydra, is a steel Floorless Coaster at Dorney Park & Wildwater Kingdom in Dorneyville, Pennsylvania. Manufactured by Bolliger & Mabillard, the coaster opened to the public on May 7, 2005. Hydra was built on the site of the former wooden coaster Hercules, which was closed and demolished at the end of the park's 2003 season. The ride's name comes from the mythological Greek story where Hercules battled the Lernaean Hydra.
