Bahamut ZERO (バハムート零式, Bahamut Type-0) is a summon from the Final Fantasy series.
Bahamut, as well as his various versions, is a commonly appearing summon in the Final Fantasy series. His first appearance was in the very first Final Fantasy, where he optionally granted the Warriors of Light (the playable characters) a class upgrade in exchange for a rat tail found in the Castle of Ordeals.
With Final Fantasy III introducing the Summon ability, Bahamut became available as the most powerful summon-able monster. His signature attack is Mega Flare, which deals heavy non-elemental damage to all targets. Final Fantasy VII introduced two new Bahamut variants, Neo Bahamut and Bahamut ZERO, which use even more powerful attacks named Giga Flare and Tera Flare respectively.
As a stage element
Bahamut ZERO appears as one of the summons on Midgar. When it appears, it attacks with Tera Flare, a flare that destroys the background and creates a continuously damaging pillar of light on the stage.
