The Joker, Wooden roller coaster at Six Flags Discovery Kingdom, California.
The Joker stretches 3,200 feet in length, reaches heights of 100 feet, and sends riders through three inversions at speeds of 53 miles per hour.
Rocky Mountain Construction transformed the former Roar roller coaster into The Joker in 2016, incorporating steel track technology onto the existing wooden support structure.
The design takes inspiration from the DC Comics character, incorporating green and purple color schemes throughout the coaster's track and station building.
The roller coaster accommodates 24 riders per train in six cars, with two rows of two seats each, utilizing secure lap bar restraint systems.
The specialized step-up under-flip inverted roll element combines with a 78-degree curved drop to create distinct riding sequences.
