Firebird is a custom Bolliger & Mabillard floorless roller coaster located at Six Flags America.

In late 1989, Six Flags Great America announced that Iron wolf would be added to the park.[1] On April 28, 1990, Iron Wolf opened on the former site of Z-Force, the only Intamin Space Diver model ever manufactured. On its debut in 1990, it was the tallest and fastest stand-up roller coaster in the world and the first roller coaster manufactured by Bolliger & Mabillard.

In 1994, Iron Wolf appeared in the movie Ri¢hie Ri¢h as Richie's backyard roller coaster.

On August 5, 2011, Six Flags Great America announced on their official Facebook page that the Iron Wolf would be closed on September 5, 2011: "After a long 21 year history at the park, we will be removing Iron Wolf. Make sure to get your last rides in – Iron Wolf's Last Stand is September 5". "The Last Stand" is also a reference for the slogan for Apocalypse.

On August 22, 2011, Six Flags America announced on their official Facebook page that they would be adding a new attraction in 2012. From this day, they began to slowly remove burnt pieces from an envelope to reveal the ride with an official announcement on September 1, 2011. On September 1, 2011, Six Flags announced that Iron Wolf would be relocated to Six Flags America, where it would open as Apocalypse, following its closure on September 5, 2011. The ride was expected to open on May 25, 2012, and be located in Skull Island section of the park where the former Skull Mountain used to be.

Apocalypse was Six Flags America's first roller coaster in a decade, since Batwing opened to the park in 2001.

On December 2011, construction sped up with footers being dug, and the track and trains began arriving. On February 28, 2012, vertical construction started with the installation of a track piece for the station. On April 2, 2012, Apocalypse's track was completed. The dismantling and reassembling of the roller coaster was handled by Ride Entertainment.[2] Apocalypse's queue line featured detailed theming, such as dead grass, rocks, a plane crashed into a rock, an abandoned truck with graffiti on it, shipping containers that riders would walk through, and numerous other abandoned-looking objects.[3]

On August 16, 2018 the park announced that Apocalypse would be "closing forever", with its last day of operation being September 8.[4] On August 30, Six Flags announced that Apocalypse would become Firebird for 2019. As part of the refurbishment the stand-up trains were replaced with new floorless trains and the ride would be repainted. The front car from one of the stand-up trains was donated to the National Roller Coaster Museum.[5]



Firebird has a twisting layout with track passing through the middle of the vertical loop. The ride does not feature any mid-course brake run, just a miniscule section of straight track. The track and supports are painted dark-pink, and the running-rails are painted silver.


2 trains with 7 cars per train. In each car, riders are arranged 4 across in a single row, for a total of 28 riders per train.
