The ride's final relocation was to Six Flags Magic Mountain in California. As part of the relocation, the ride was renamed from Z-Force to Flashback. It opened at the park in 1992.
In 2003, the ride was closed and remained standing but not operating until 2007. On January 23, 2007, the park announced that Flashback would be removed along with Psyclone. Originally, the park stated that Flashback may be re-built within the park for 2008, however it was dismantled and scrapped in December 2007.
Flashback was the world's only hairpin-drop roller coaster, with 6 head-over-heels dives and a 540-degree upward spiral. It was all packed into a relatively small area with 1,900 feet (580 m) of track stacked above each other. The drops were severe, producing a free-fall experience on the plunges; fast steel switchbacks connected the turns just before trains flew into the gravity-defying upward spiral. Trains reached a max of 35 miles per hour (56 km/h), with a 3-g force on the one and a half minute ride.
The ride featured three trains, each with five cars. Each car featured riders arranged 4 across for a total of 20 riders per train. The trains were manufactured by Giovanola. Riders were required to be 48 inches (120 cm) tall to ride.
