Firebird is a floorless roller coaster located at Six Flags America in Prince George's County, Maryland. The roller coaster had originally debuted in 1990 as a stand-up roller coaster named Iron Wolf at Six Flags Great America. It was later relocated to Six Flags America in 2012 and renamed Apocalypse, under which it operated until 2018.
The roller coaster was the first to be built by Swiss manufacturer Bolliger & Mabillard. When known as Iron Wolf, the roller coaster briefly held world records among stand-up roller coasters for height (100-foot or 30-metre) and speed (55 miles per hour or 89 kilometres per hour) before being surpassed several years later.
