King of Dragons. Elements in his body combine to generate a nuclear fusion blast.
Bahamut is obtained by defeating Deathgaze. Deathgaze is found in the skies randomly by flying around on the Falcon, and after a few battles, when his HP is finally depleted, will drop the Bahamut magicite.
If Deathgaze is killed via the Vanish-Doom bug, it will delay its final attack and the party will not receive Bahamut's magicite; Deathgaze will not count as defeated, meaning the player must find it again on the world map and battle it again to receive Bahamut.
Bahamut costs 86 MP to summon, and casts Mega Flare (Sun Flare in earlier translations). It damages all enemies with non-elemental damage, has a Spell Power of 86, and is unblockable.
Bahamut can also be summoned using the Slot ability by aligning three dragon symbols.
Bahamut (Arabic بهموت Bahamūt) originated as an enormous whale in ancient pre-Islamic Arabian mythology. Upon Bahamut's back stands a bull with four thousand eyes, ears, noses, mouths, tongues and feet called Kujuta (also spelled "Kuyutha"). Between each of these is a distance of a 500-year journey. On the back of Kujuta is a mountain of ruby. Atop this mountain is an angel who carries six hells, earth, and seven heavens on its shoulders.
Another version of the Arabic story is that Bahamut is indeed a dragon and he stands on a whale called Liwash.
In modern times, the game Dungeons & Dragons is responsible for re-imagining Bahamut as the king of dragons, a benevolent Platinum Dragon; the opposite of the malevolent Tiamat, the five-headed Chromatic Queen of Dragons.
