Harley Quinn's Jestermania

Harley Quinn's Jestermania was a wooden roller-coaster at Six Flags Jetania. It was built in 1940 and is the oldest rollercoaster in the park.

The rollercoaster was originally built for Whalom Park in Lunenburg, Massachusetts, United States. It had a tunnel, the Black Hole, added in 1990.

In 2006, the ride was purchased by Six Flags from Global Developments. It was shipped over to Jetania where it was reassembled at Six Flags Jetania and rethemed. The Black Hole tunnel was rethemed to Arkham Asylum and the rest of the coaster was rethemed to Harley Quinn and the Joker, two characters from the Batman comics.

The ride will be moved to Six Flags Cybersland where it will retain it's name and look to accompany Quinn. However, it will repainted and redecorated to include The New 52 versions of Harley and the Joker unlike Quinn which will feature the classic versions of Harley and the Joker.
