Hydra The Revenge, a $13 million floorless, multielement, roller coaster opened at Dorney Park on May 7, 2005 on the site where the Hercules wooden coaster once stood. Themed after Greek Mythology, Hydra was a horrible serpent with multiple heads that could grow back as soon as they were cut off. Hercules was once tasked with twelve labors in order to be forgiven for a crime he committed, and one of the labors was to kill Hydra.
Hydra The Revenge begins with a unique feature called the JoJo roll, the first-ever pre-lift hill inversion where riders twist upside-down after exiting the launch station. With adrenaline pumping, riders climb up a 95-foot-tall lift hill, followed by a plunge down a menacing 68-degree, 105-foot sideways drop into a rock-hewn canyon. This "near-miss" race through the canyon is followed by a 65-foot tall inclined dive loop that drops the train back into the ravine before being shot through a zero-gravity roll carrying the train out over the midway. The coaster races through the first of two flat-spin inversions, plunges 50 feet into another ravine, and rises into Hydra's signature element – a tight cobra roll – before dropping back into the same ravine.
