Defeating Belgemine's Bahamut the first time awards the player the Flower Sceptre, and Mana Sphere x8 from then on.
At the end of the game, Bahamut is fought before the final boss, Yu Yevon, while he searches for an aeon to possess. Its stats at this time are identical to the stats Bahamut had while used by the player, but it is only able to use its normal attack, Impulse, and Mega Flare.
Bahamut appears as an enemy.
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.
