Big Fury was a compact steel roller coaster at Six Flags Great Adventure, that operated from 1974 to 1977. It was a Pinfari Zyklon model Z64.

Big Fury was removed and sold to an unknown buyer and replaced by a Schwarzkopf Wildcat (54 m) called Wild Rider. Although Wild Rider had larger drops than a Zyklon and the two were painted different colors, this roller coaster is often confused with the Wildcat roller coaster that replaced it.

When it opened, El Toro had the steepest drop of any wooden roller coaster in the world at 76 degrees, a record that was later broken by T Express at Everland in 2008. Among wooden coasters, its height of 181 feet (55 m) ranks fourth, its drop height of 176 feet (54 m) ranks second, and its maximum speed of 70 mph (110 km/h) ranks third.

Alpen Blitz was a compact steel roller coaster that operated at Six Flags Great Adventure from 1976 to 1978. It was designed by Anton Schwarzkopf.At the end of 1974, it was determined that Great Adventure needed two additional roller coasters and an additional flume ride to accommodate huge crowds. So they purchased compact and inexpensive coasters called Jumbo Jet and Big Fury. Big Fury opened in the spring of 1975. Jumbo Jet was removed a month after it was built by the end of August in 1975. To replace Jumbo Jet, "Alpen Blitz" was purchased and was built on the site Jumbo Jet was to have occupied. The Alpen Blitz was located in the area later occupied by the "Haunted Castle". Autobahn Bumper Cars are in this area today. By 1977, Great Adventure management began to build a steel looping coaster that would be known as Lightnin' Loops. At that point, Six Flags purchased the park. After the 1978 season when "Lightning Loops" opened, it was determined that Alpen Blitz was no longer needed. It was sold and removed to make room for other flat rides. Big Fury was also sold and replaced with the Wild Rider at the end of the 1977 season.

The Haunted Castle was a haunted attraction at Six Flags Great Adventure amusement park in Jackson Township, New Jersey. The original Haunted House was built prior to the fall "shoulder season" of 1978 to boost attendance and as a test for building a larger facility the following year. While it was intended that it be open only at night, the popularity of the attraction caused management to open it at the beginning of the day and keep it open until the park closed. At the end of the 1978 season, the attraction was disassembled and sent to Six Flags Over Mid-America, where it would continue to run from 1979 through 1982. The old façade was torn down and Botanical Gardens took its place. A medieval-styled façade was built for the Haunted Castle on the site of the Alpen Blitz across from the Muzik Express. On May 11, 1984, a fire destroyed the attraction, trapping and killing eight teenagers. Six Flags Great Adventure and its parent company Six Flags were indicted for aggravated manslaughter and accused of recklessly causing the deaths by taking inadequate precautions against a fire. In the trial, the prosecution argued that repeated warnings by safety consultants to install sprinklers or smoke/fire alarms had been ignored. The defendants denied any culpability. They contended that the fire was arson, and that no amount of precautions would have saved lives. The trial jury found the defendants not guilty of criminal charges; however, Six Flags paid millions in civil damages to victims' families.
