Viper
Viper opened in May 1990.  It was built by Arrow Dynamics.

It is a little confusing since the Six Flags chain at one point had six different coasters called Viper.  Here are the other five:

• Viper (1989-2005) at Six Flags AstroWorld was a looping Schwarzkopf coaster.
• Viper (1982-present) at Six Flags Darien Lake is an Arrow steel coaster with five inversions.
• Viper (1995-present) at Six Flags Great America is a wood coaster based on the Coney Island Cyclone.
• Viper (1995-2004) at Six Flags Great Adventure was a steel TOGO that featured a Heartline Roll.
• Viper (1995-2001) at Six Flags Over Georgia was a first generation Schwarzkopf Shuttle Loop that used a weight-drop to launch the train.
