Dark Bahamut is an optional boss in the International, PAL and HD Remaster versions of Final Fantasy X. It can be encountered by returning to Zanarkand Dome after obtaining the Fahrenheit, in the spot where the party fought Yunalesca.
Dark Bahamut is one of the most difficult Dark Aeons to defeat. After every five of player's attacks (excluding counterattacks) Dark Bahamut counters with Impulse, which can KO unprotected characters and will shatter the character if they are petrified rendering them out of action for the rest of the battle. It also inflicts Slow, Full Break, and Delay (strong) — in the case of Slow, this will ignore Slowproof or Ribbon; though Auto-Haste will still protect against it.
If the player does not have any Ribbon or Stoneproof armor to survive Impulse, there is an easy, but long/boring way to defeat him: all party members must have Counter-Attack or Evade & Counter abilities. The party should use Aim and wait for Dark Bahamut to attack: the counterattacks will slowly kill him. The party's HP and Defense together must be enough to be sure of surviving Dark Bahamut's physical attacks.
A risky tactic for parties having trouble hitting him due to Dark Bahamut's tendency to dodge physical attacks is to set Overdrive Mode to Stoic, then use Impulse to 'farm' Overdrives, which are guaranteed to hit him; as Impulse inflicts Full Break, the player should dispel them from two of the three party members, and the third will have their gauge maxed out when struck; the auto-abilities mentioned above can help make this less difficult to maintain due to having to reapply Protect and Haste. This trick can also be used against Dark Yojimbo, using Kozuka to inflict the required breaks.
Mega Flare can be survived by summoning an aeon or by casting Auto-Life on everyone. The Overdrive doesn't seem to be as damaging compared to those of other Dark Aeons. Party members with Break HP Limit at around 50,000 before Dark Bahamut executes his Mega Flare will also survive it. After soaking the damage, the party should fully heal with Final Elixir mix, then rinse and repeat. It helps if all party members have Strength, Defense, and Agility at 255. Luck is good at 80 or higher.

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.
