track forward and in reverse and features two completely vertical drops and three inversions. It opened late in 2001, but suffered a lot of downtime. X was designed by Arrow Dynamics, as the world's first "fourth-dimensional" roller coaster. It was the only one in North America where riders experience going 360 degrees in their seats. Each seat lies on a separate axis from the track. This coaster managed to open briefly on January 12, 2002, only to close due to more technical problems. It reopened late in August of that year. The ride closed for a major refurbishment and re-theme in 2008 where X transformed into X². In 2003, Scream, designed by Bolliger & Mabillard was added.

It was much larger than the other three Bolliger & Mabillard Flying Coasters at other Six Flags parks, all named Superman: Ultimate Flight. Tatsu has a suspended-track orientation featuring vehicles that recline passengers with their backs against the track and facing the ground. This brought the park up to 17 roller coasters, to tie with Cedar Point for the greatest number of roller coasters in a park (albeit Flashback had been standing but not operating for an extended period of time and thus it is debatable whether the park could claim 17 as its number of roller coasters). 2006 attempted sale On June 22, 2006, Six Flags, Inc. announced that it was exploring options for six of its parks, including Magic Mountain and its neighboring water park, Hurricane Harbor. Though management said closing the park was unlikely, rumors still began that the park could be sold to real estate developers, with an intent to close the park and build housing developments in the area. Park officials cited dwindling attendance due to rowdy behavior among some of the park-goers as reasons for wanting to sell the park while management
