The Joker (Chinese: 小丑) is a steel roller coaster with three inversions. The ride is currently located at Six Flags Taiwan in,. The coaster was fabricated in 1989 by BHS and was designed by Schwarzkopf and Ing.-Büro Stengel GmbH. It originally ran as Aktion-Bahn from 1990-1995 on the German fair circuit, then as Autobahn at Kid's World from 1996-1997, and as Magic Coaster at Yangju Amusements Land from 1998-2001. It has similarities to Alpina-Bahn,, and.

History
It debuted as Aktion-Bahn at the 1990 Oktoberfest in Hamburg. It operated on the German fair circuit under showman Rudolf Barth for 6 years before spending 2 years at Carwardine Parks' Kid's World in, as Autobahn, and then 4 years in  at Yangju Amusements Land as Magic Coaster.

While at Yangju Amusements Land, on August 5, 2001 a derailment of the last car of the train resulted in 7 injuries (much like fellow Schwarzkopf coasters Mindbender and Quimera, however there were no casaulties due to the ride being located in a grassy area that helped cushion the landings of the riders). The government ordered the coaster shut down, and Yangju Amusements Land quickly shut the ride down and removed it.

It arrived at it's current location of Six Flags Taiwan in late 2001, where it was repainted into a similar green and purple color scheme to at, opening on June 3, 2002 as The Joker to positive reception from guests and riders. The "Franksteined" car set used at Yangju Amusements Land had been replaced with a spare car set from another Schwarzkopf coaster,. Six Flags Taiwan had to reconstruct the manual using a translation of a backup of the original German manual for the coaster (which previous owner Rudolf Barth let Six Flags borrow for the purposes of reconstructing & translating the manual), as the previous manual used by Yangju Amusements Land (which had been translated from German to English and then to Korean) had been seized as evidence in legal action against Yangju Amusements Land (who were found to only be partially at fault).

In 2007, the coaster received the old Premier Rides trains from Batman & Robin: The Chiller, the old 2002 Schwarzkopf trains were sent to FairCon. In 2008, the Lap Bars were replaced with T-Bars.

In 2017, a tunnel named "Harley Quinn's Tunnel of TERROR" (Chinese: 哈雷奎因的恐怖隧道) was added to the ride.
