Six Flags Discovery Kingdom plans to transform the existing Roar wooden coaster into a taller, faster and steeper wood-steel hybrid coaster dubbed The Joker that looks like a contender for best new ride of 2016.

Set to debut in the Spring, the renovated coaster at the Vallejo amusement park will feature 15 airtime hills and three inversions, including a zero-G barrel roll.
The Joker will also include a world's first element called a “step-up under-flip inverted roll” that twists riders upside down as they head uphill before emptying them into a 270-degree hairpin turn.
