Lex Luthor: Drop of Doom, Drop tower at Six Flags Magic Mountain, California, US.

Lex Luthor: Drop of Doom is a drop tower at Six Flags Magic Mountain in California that features two separate gondolas mounted on an existing coaster structure. Riders ascend slowly before experiencing a rapid free-fall descent that lasts only a few seconds.

Announced on September 1, 2011, the Intamin drop tower was built onto the existing Superman: Escape from Krypton structure, with pieces lifted by helicopter in April 2012 and testing starting June 22. It opened July 7, 2012, taking the tallest drop tower title from The Giant Drop. Zumanjaro: Drop of Doom surpassed it on July 4, 2014; after Zumanjaro closed in 2024, it reclaimed the title.

The queue winds through a mock Lexcorp headquarters, past posters for LexAir, LexPower, Lexcom and Lexcorp, a wall of weapons blueprints and Lex Luthor's power suit. Recorded announcements have Luthor thanking visitors for volunteering to test his newest project, with ominous asides hinting something is wrong. A door marked Research & Development serves as the Flash Pass entrance.

Riders must be at least 48 inches (121 cm) tall, and each seat has an individual over-the-shoulder restraint. The park rates the ride at maximum intensity and bars guests with acrophobia, high blood pressure, diabetes, epilepsy or pregnancy. A single-rider line sits near the exit.

This ride shares its support structure with an adjacent roller coaster, making it one of the few attractions where two separate rides use the same tower. This clever design allowed the park to add a major thrill without requiring extra space.
