Dark Bahamut is an optional boss in the International, PAL, and HD Remaster versions of Final Fantasy X. He can be fought by returning to Zanarkand Dome after obtaining the Fahrenheit, in the spot where the party fought Yunalesca. The theme for the battle is called "Challenge". He must be defeated to acquire the Sun Crest for Tidus's Celestial Weapon Caladbolg if the player missed picking it up it after defeating Yunalesca.



Dark Bahamut is one of the most difficult Dark Aeons to defeat. After every five of a player's attacks (excluding counterattacks), Dark Bahamut counters with Impulse, which can KO unprotected characters, and will shatter the character if they are petrified, taking them out of action for the rest of the battle. It also inflicts Slow, Full Break, and Delay (strong)—Slow ignores Slowproof and Ribbon, but Auto-Haste will still prevent it.

Dark Bahamut has a very high Luck stat, thus evading most normal attacks, no matter how high the character's Accuracy is, unless they also have a high Luck stat themselves and/or use Aim.

Dark Bahamut's Overdrive, Mega Flare, inflicts Delay (strong) and deals between 40,070 to 45,246 damage to the whole party. It also removes most beneficial status effects, except for Auto-Life. His Overdrive gauge increases by 10% when using his physical attack or when targeted by an ability.


Good armor abilities to have are Ribbon, Auto-Haste, Auto-Phoenix, and Auto-Protect. While Stoneproof armor is useful, Ribbon is always the best option.

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: one character should have a weapon with Counterattack or Evade & Counter, and use Sentinel every turn. If this character does not have enough Luck to hit Dark Bahamut, they should be given the effects of Aim 5 times as well. The character's HP and Defense must be high enough to survive Dark Bahamut's physical attacks. Having Protect, Cheer and/or armor with Defense +20% can help with this. It is also possible to do this without using Sentinel (by having the entire party defend before Dark Bahamut attacks), but this is less convenient since the entire party must then be capable of surviving and counterattacking.

A risky tactic for parties having trouble hitting him due to Dark Bahamut dodging 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 is not 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 the Final Elixir mix. It helps if all party members have Strength, Defense, and Agility at 255. Luck is good at 80 or higher.

As with any other enemy, Dark Bahamut can be killed instantly by Yojimbo's Zanmato attack. This can be used to obtain Sun Crest needed to power up Caladbolg if the player missed it. However, this will likely take multiple attempts since the probability of Yojimbo using Zanmato is low, even when his compatibility with Yuna is high.

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.
