Wonder Woman Golden Lasso Coaster is a steel roller coaster at Six Flags Fiesta Texas, built by Rocky Mountain Construction and opened on May 12, 2018.^[1] The roller coaster is themed to the DC Comics character, Wonder Woman.^[2][3] It was one of two prototype single-rail coasters to open in 2018, the other being RailBlazer at California's Great America, which has a mirror-image layout to the Wonder Woman Golden Lasso Coaster.

Six Flags Fiesta Texas announced the closure of Power Surge in mid-summer 2017.^[3][4][5] Power Surge was closed on July 23, 2017. The park began teasing a new attraction for the 2018 season and on August 3, 2017, the park officially announced a first of its kind roller coaster, introducing the new Rocky Mountain Construction single-rail coaster concept.^[3]

The roller coaster was originally planned to open on March 10, 2018, with a soft opening a week prior for an added bonus to the park's inaugural Botánica Music Festival.^[6] However, it was delayed twice until opening in May.^[7]

The coaster closed on July 5th 2023 for a 2-Phase refurbishment. The ride is set to reopen in late 2023 once phase 1 of the refurbishment is complete, but will close again in 2024 where the coaster will receive new trains. ^[8]

The ride begins by exiting the continuously moving station and ascending a 113 feet (34 m) tall chain lift. The train then banks right making a 180 degree turn and entering a 100 feet (30 m) tall 90 degree drop, diving and reaching a maximum speed of 52 miles per hour (84 km/h) before entering by a dive loop. The train then rises up to the left into an airtime hill and then drop again, entering a hill followed by several turns. After the turns it drops and turns into a cutback, followed by a corkscrew. The train finally goes through an over-banked turn to the right before hitting the brake run.
