King Cobra was a steel stand-up roller coaster that operated at Kings Island in Mason, Ohio, from 1984 to 2001. Manufactured by the Japanese company Togo and designed by James Rogan, it stood out in coaster history as the first stand-up roller coaster in the world designed from the ground up in that configuration, rather than converted from an existing sit-down model.
King Cobra was built in the park’s Action Zone section and tested a prototype at Togo’s Tokyo facility, where it was known as the Astro-Comet, before Kings Island purchased and installed it. Guests at the park even helped choose its final name. For nearly two decades it gave riders an upright view of a 90-foot drop and a signature vertical loop before parts shortages forced its retirement.

The Ride Experience
Riders on King Cobra stood upright in restraints rather than sitting, a novel sensation at the time that made the coaster’s 95-foot lift hill and subsequent 90-foot drop feel more intense than on a traditional sit-down layout. The ride’s centerpiece was a 66-foot vertical loop, its single inversion, followed by a tight 540-degree helix before returning to the station. The full circuit covered 2,219 feet of track at speeds up to 50 mph and lasted about two minutes.
With two six-car trains carrying riders two across in two rows, King Cobra could move roughly 1,250 guests per hour, a respectable throughput for a stand-up coaster of its era. It cost about $3 million to build and quickly became one of the signature attractions in Kings Island’s Action Zone.
Closure and Legacy
King Cobra’s downfall came after Togo filed for bankruptcy in 2001 amid unrelated litigation involving another Togo-built coaster, which made replacement parts nearly impossible to source. Kings Island permanently closed King Cobra that November after 17 seasons of operation. Its track was eventually scrapped, while its trains were sent to Kings Dominion as spare parts for that park’s Togo-built Shockwave.
The Action Zone plot where King Cobra once stood went on to host several later attractions, including SlingShot, Delirium, Banshee, and Cargo Loco, but King Cobra is still remembered by longtime park visitors and coaster historians as a genuine trendsetter in stand-up coaster design.
