Arkham Asylum - Shock Therapy is themed around the psychiatric hospital that appears in a number of DC Comics stories. The ride's storyline centres around Batman's enemy The Joker escaping from the asylum, with other criminally insane characters such as Harley Quinn and Killer Croc also featuring.
The Vekoma Suspended Looping Coaster was previously based on Mel Gibson's Lethal Weapon movie franchise, and was the first inverted coaster to open at an Australian theme park when it debuted in 1995. Standing at 109-feet-tall, it hits a top speed of 55 miles per hour during its 2,510-feet circuit.
As part of the conversion to its new name in 2012, the coaster received all-new trains from manufacturer Kumbak. These are equipped with an on-board audio system to help bring the Arkham Asylum - Shock Therapy storyline to life. The ride also features an updated queue line, with the entrance being located next to the Superman Escape roller coaster.
