In 2003, Scream, designed by Bolliger & Mabillard was added. At this point, Six Flags Magic Mountain tied with Cedar Point for the park with the most roller coasters in the United States. Scream is similar in concept with Medusa at Six Flags Discovery Kingdom and is a mirror image of Bizarro at Six Flags Great Adventure. It is a floorless roller coaster with trains riding above the rails traversing seven inversions on of track on floorless trains. In 2006, Tatsu, a Bolliger & Mabillard flying roller coaster was added, causing a temporary closure of Revolution to allow construction to take place. It was much larger than the other three Bolliger & Mabillard Flying Coasters at other Six Flags parks, all named . 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).
