On August 16, 2018, the park announced on their social media platforms that Apocalypse would close on September 8, 2018. On August 30, 2018, instead of being demolished or relocated, it was announced that Apocalypse would be converted into a floorless coaster and renamed Firebird for the 2019 season. It is the third Bolliger & Mabillard stand-up coaster to be converted into a floorless coaster, after Cedar Point's Rougarou (previously known as Mantis) and California's Great America's Patriot (previously known as Vortex).
