The roller coaster’s backstory revolves around the evil Dr. Diabolical and her nefarious quest to let menacing creatures loose on the world. To achieve her “diabolical” goal, she has constructed a means of capturing the essence of human adrenaline and fear – and thrill-seekers are lining up to experience it.

After boarding the meniacal machine, riders are cranked up the lift hill and suspended face-first above the coaster’s 95-degree, beyond-vertical drop for a few terrifying moments before being released into a 150-foot dive, making a swooping circuit around an Immelmann inversion, enduring a 270-degree Zero-G roll, then shooting down a 75-foot near-vertical drop followed by a wild banked turn, straight into extreme air time, and finishing with a high-speed spiral.
