Bahamut (Final Fantasy VI)

Bahamut is an esper in Final Fantasy VI who can be acquired as a magicite.

Obtained
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.

Battle
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.

Magicite
Bahamut is equippable as a magicite and teaches Flare at a rate of x2. When leveling up, Bahamut provides a +50% boost to HP.
