Originally called the Thriller, this ride was operated as a travelling coaster throughout Germany. It was built in 1986 and arrived at AstroWorld in 1998. In 2001 new trains were introduced and after only a few hours of operation the ride was closed and has not opened since! This is a real shame, as the ride looks absolutely awesome. It is said to pull an insane 6.5-g's as it traverses four inversions and several steep drops of up to 70º.
The ride was dismantled at the end of the 2002 season, and relocated to Six Flags Marine World as Zonga in 2003.
