Vipère, Steel roller coaster in Valencia, California

Green Lantern: First Flight was an Intamin ZacSpin steel coaster at Six Flags Magic Mountain in Valencia, California, with a 251 m track reaching 32 m and 60 km/h. Its green track of welded triangular trusses curves into a large loop, and the leaf-shaped cars hang riders on either side of the rail, rotating freely about a horizontal axis.

The ride debuted in 2011 as Green Lantern: First Flight at Six Flags Magic Mountain and was the first of its model type in North America. After closing in 2017, the attraction was relocated to Montreal and given its new name.

The ride was themed to the DC Comics superhero Green Lantern, with each of its five cars shaped like a shuriken. A 10-foot-tall lantern icon that glowed green at night marked the entrance, where the Green Lantern battery stood. Its name also matches a DC Animated Universe film.

The ride stood in the DC Universe section of Six Flags Magic Mountain, in the spot formerly occupied by Gotham City Backlot. Its loading station was later reused for Wonder Woman Flight of Courage in 2022. The relocated Vipère at La Ronde never opened: its track and supports stayed in storage until they were cleared during the 2022–2023 winter closure.

Green Lantern's rotation was not choreographed like X2's; the cars spun freely from unequal gravitational pull on either side of the axis, so each ride differed. A mechanical flaw once left trains stuck upside down, and the fix that reduced spinning produced shaky, painful movements. Its five cars were shaped like shuriken.
