Mr. Freeze
Mr. Freeze: Reverse Blast, previously known as Mr. Freeze, is a shuttle roller coaster located at Six Flags Over Texas in Arlington, Texas and Six Flags St. Louis in Eureka, Missouri. The steel coasters feature a linear induction motor (LIM) launch system that accelerate riders from in 3.8 seconds. The two installations are mirror images of one another and are based on the famous Batman villain Mr. Freeze. Originally, they were themed after the 1997 film "Batman &amp; Robin" prior to a conversion in 2012 to operate backwards.
