The Psyclone on March 23, 1991. It was based on the original Coney Island Cyclone, which opened in 1927. The ride had eleven hills, five high-speed banked turns, and a 183 foot (56 meter) long, dark tunnel before the lift hill.
The ride sustained structural damage after the Northridge earthquake in 1994 and though repaired to operate safely again, the ride dynamics suffered greatly in regards to vehicle tracking. Major modifications happened, including adding trim brakes that slowed the trains down to the point of crawling through each turn. The heavy trains took their toll on the track structure, and the coaster became very rough. Because of this, ridership at the attraction had drastically declined, due in part to having earned a poor reputation among park visitors. A 2006 poll of roller coaster enthusiasts ranked Psyclone 178th out of 179 wooden roller coasters worldwide.
On January 23, 2007, the park announced that Psyclone would be demolished for future expansion, following the closure of another roller coaster in the park, Flashback. The coaster closed at the end of the month. That spring, Psyclone was torn down and the location was blocked from guests' view with a sign stating that the land would be reserved for future attractions.
Psyclone was dismantled and scrapped during the last week of February 2007. The area of the park where Psyclone once stood is now occupied by another wooden coaster, Apocalypse.
Psyclone's trains, built by Bolliger & Mabillard, were later run backwards on Colossus during Halloween events. It was one of only two roller coasters not built by B&M to have their rolling stock, the other being Steel Dragon 2000.
