Green Lantern (Six Flags Great Adventure)

Green Lantern is a steel stand-up roller coaster located at Six Flags Great Adventure in Jackson Township, New Jersey. Green Lantern stands 155 ft tall and features a top speed of 63 mph. The 4155 ft ride features five inversions and a duration of approximately 2$1/2$ minutes. The ride was manufactured by Swiss firm Bolliger & Mabillard.

The ride originally operated at Six Flags Kentucky Kingdom in Louisville, Kentucky from 1997 to 2009, where it was known as Chang. Upon opening in 1997, it set world records for this type of coaster in height, drop, speed, length and number of inversions. The introduction of the ride caused Kentucky Kingdom to achieve record attendance levels. After Six Flags abandoned Kentucky Kingdom in 2009, the ride was relocated to Six Flags Great Adventure. The ride debuted in 2011 as Green Lantern, replacing the former Great American Scream Machine roller coaster.

Chang (1997–2009)
Chang ("long" in Mandarin Chinese) opened at Six Flags Kentucky Kingdom on April 4, 1997, setting world records for this type of coaster in height, drop, speed, length and number of inversions. When it debuted, Chang had a yellow track and supports. The ride was constructed by Martin & Vleminckx. Around 1999, its track was painted lime green and the support columns violet. In early-2006 the track was returned to its original yellow, while the supports were painted blue. Six Flags originally announced that the ride would have a Batman theme, along with its T2 coaster. T2 was expected to be known as "Batman: The Ride" and Chang "Riddler's Revenge", but those plans were later canceled.

Chang was removed over the weekend of September 19, 2009 to expand Splashwater Kingdom, but the proposal for the expansion was scrapped, while Six Flags later announced plans to dispose of its Kentucky Kingdom property. The removal of Chang and the closure of Six Flags Kentucky Kingdom caused the owners of the park land (the Kentucky State Fair Board) to sue Six Flags for ownership of the rides. Kentucky Kingdom is now open under new operators as of May 24, 2014.

Green Lantern (2011–present)
In 2010, parts from Chang reportedly appeared at Six Flags Great America. The ride was planned to be moved to Six Flags Great America in 2011; the park obtained approval to exceed the 125 ft height limit imposed on the park, but plans were later canceled in favor of a water park expansion.

On July 5, 2010 Six Flags Great Adventure announced that its Great American Scream Machine would close on July 18 to make way for a new attraction the following year, sparking rumors that Chang would move there in 2011. Although Six Flags did not confirm the speculation, a first look at the park's new-ride layout from the Jackson Township zoning board meeting was posted on the JTown Magazine website and the layout was identical to that of Chang.

On September 16, Six Flags Great Adventure announced that it would open a Green Lantern-themed roller coaster in 2011. The specifications released for the new ride matched those of Chang. As part of the relocation, the ride would receive technical renovations and a new coat of paint.

Footers were poured for the ride in December 2010, with track installation beginning the following month. In January 2011, construction of the lift hill was completed. In April 2011 the final pieces of track were put in place.

On May 19, Green Lantern soft-opened to a select group of season-pass holders, media and families from Children's Miracle Network. The ride opened to the public on May 25.
