Diamondback is a steel hypercoaster built by Swiss manufacturer Bolliger and Mabillard and is one of ten Mega Coaster models designed by the group. As in all B&M Mega Coasters, the emphasis of Diamondback is placed on airtime hills meant to create a sensation of weightlessness.

Diamondback is 230 feet tall and travels at a maximum speed of 80 miles per hour. Notably, it features a "scoop"-created splashdown in a concrete pool, a feature that is otherwise present only on B&M's Dive Machine models.

Chronologically, Diamondback's closest sister rides are Behemoth and Intimidator at Canada's Wonderland and Carowinds respectively, two of Kings Islands sister parks.
