Mr. Freeze, Hypercoaster at Six Flags Over Texas in Arlington, US.

Mr. Freeze is a steel shuttle roller coaster at Six Flags Over Texas in Arlington, Texas. Its linear induction motors launch a five-car train from 0 to 70 mph (113 km/h) in 3.8 seconds through a 190-foot tunnel into a 150-foot-tall inside top hat, the ride's only inversion, followed by an overbanked turn and a 218-foot vertical spike. The train then retraces the track backward and is slowed on the launch section.

Announced on December 18, 1996, Mr. Freeze was to open in May 1997 alongside Batman & Robin, but overheating LIM motors delayed it to 1998. Premier Rides built it as the mirror of the Six Flags St. Louis coaster. Trains ran backward from 2012 as Reverse Blast; in 2022 forward operation returned, and since July 2023 one train launches forward and one backward.

The theme comes from the 1997 film Batman & Robin: riders enter Snowy's Cones, an abandoned ice cream factory that serves as Mr. Freeze's hideout, passing under the mouth of the building. Inside, the lower level holds a mixer and four flavour containers — vanilla, chocolate, strawberry and orange — and a sign reads "Home Of The Big Freeze".

Riders must meet a minimum height requirement to board, and loose items should be stored securely before entering the queue. Two separate loading platforms allow trains to be loaded and unloaded at the same time, reducing wait times during busy periods.

The track's only inversion is an inside top hat, and the 66.4 m (218 ft) vertical tower is reached with help from extra LIMs mounted on the ascent. The station has two sliding launch tracks, so one train can be loaded while the other is dispatched, a setup rare among shuttle coasters.
