The coaster was manufactured by Gerstlauer and traverses a total 1,886.5 feet (575.0 m) of track both forwards and backwards, at a top speed of 52.8 mph (85.0 km/h).

During the IAAPA Expo 2017 in November 2017, Walibi owner Compagnie des Alpes and German manufacturer Gerstlauer signed off on a new upcoming coaster project.

[1] On December 8, 2017, Compaigne des Alpes and Walibi announced the addition of a yet-to-be-named coaster to celebrate the park's 40th anniversary in 2019, with an animated rendering showing off the full layout of the attraction.

[2] The coaster would be incorporated into a new area, Festival City, being built in the southwest corner of the park, where three new Zamperla rides were scheduled to debut in 2018.

[3] It would also contribute towards a 10-year, €25 million investment plan into the park, which had been kicked off in 2016 with the Gravity Group wooden coaster Timber.

Mystic features a vertical Lift hill and three inversions; a Zero-G Roll, a Dive Loop, and a twisted rollback spike.

The Flash: Vertical Velocity at Six Flags Discovery Kingdom in Vallejo, California, was also credited as the inspiration for the twisted rollback spike.
