Back in the fall, Six Flags made a joint announcement as they have in previous years that announced the new attraction(s) coming to each of their parks for the coming season. For Six Flags Great Adventure in New Jersey, that attraction was the Total Mayhem 4-D Free Fly Coaster, the first of its kind on the east coast.
On Wednesday, Six Flags officially announced that the ride would no longer be called Total Mayhem, and instead will open as The Joker. Six Flags Discovery Kingdom in California will also open a coaster called The Joker, but that ride is a refurbishment being done by Rocky Mountain Construction of the wooden coaster formerly named Roar.
Ironically, the New Jersey ride is an exact copy (except for color scheme and name) of a ride named Batman: The Ride, a coaster that opened at Six Flags Fiesta Texas near San Antonio for the 2015 season.
