On December 18, 1996, Six Flags Over Texas announced that Mr. Freeze would be added to the park. Mr. Freeze was planned to open in 1997 with the release of Batman & Robin. Arnold Schwarzenegger and George Clooney were scheduled to appear at the opening of Gotham City at Six Flags Over Texas and be the first people to ride it, but problems with the LIM system delayed the opening until 1998. This was the main reason why Schwarzenegger never appeared. The ride itself was fabricated by Intermountain Lift, Inc. When it first opened, Mr. Freeze used over-the-shoulder restraints, which were replaced with individual ratcheting lap bars for the 2002 season at both locations. In June 2006, all Premier Rides' LIM roller coasters were closed as they underwent emergency inspection after an accident on the now-defunct where a wheel fell off on the lowest part of the track. This problem apparently existed on all of Premier Rides' coasters with booster LIMs. New wheels and bearings were ordered and replaced. Both roller coasters were originally painted in light blue. The Texas Mr. Freeze received a new paint job that was completed in 2007. Now, the rest of the track is painted a bright red and the supports are dark blue. For 2009, the St. Louis Mr. Freeze was repainted with dark blue track and supports.
Mr. Freeze: Reverse Blast (2012–present)
On March 22, 2012, Six Flags announced that both versions of Mr. Freeze roller coasters at Six Flags Over Texas and Six Flags St. Louis would feature backwards facing trains and be renamed Mr. Freeze: Reverse Blast. The St. Louis version reopened on May 5, 2012, with the help of David Freese. The Over Texas version reopened on May 12, 2012, and also Vanilla Ice helped open the ride up and had a concert.
Two-train operation
Unlike most other shuttle roller coasters, Mr. Freeze is able to simultaneously operate two five-car trains because of an innovative sliding platform in the station. One train loads and unloads on either the right or left side of the station while the other train is launched out onto the main track. When this train returns to the station, it slides to the unused side of the room and unloads as the other train slides to the middle and launches. These trains are launched by 116 linear induction motors that help them achieve a top speed of in 3.8 seconds.
Ride experience
Riders enter an old, abandoned ice cream factory that has now become the hideout of Mr. Freeze, one of Batman's most famous supervillains. Although the ride was originally based on Batman & Robin, the statue that can be seen in the station seems to be based on . The ride begins when the alarm is sounded and riders are boosted backwards through a tunnel and up into a -tall inside top hat that flips riders completely upside-down. This element is followed by a overbanked turn that banks riders at a 140-degree angle and a vertical spike. As the train climbs this spike and slows, it is gently pushed up almost all the way to the top by another set of LIMs. The train then freefalls down the tower back through the course.
