Bahamut is one of the most difficult Dark Aeons to defeat. Good armor abilities to have are Ribbon, Auto-Haste, Auto-Phoenix, and Auto-Protect. After every five player's attacks (Counterattacks do not count), Dark Bahamut counters with Impulse, which can Petrify the characters who are not protected against it, and will shatter the character if they are KOed as well and they will be out of action for the rest of the battle. It also inflicts Slow, Full Break, and Delay.
While Stoneproof armor is useful in this battle, Ribbon is always the best option, and Slow, which can be dangerous, can be prevented with Auto-Haste. The counterattack can be avoided entirely by having a character cast Sentinel.
If the player does not have any Ribbon or Stoneproof armor to survive Impulse, there is an easy, but rather long/boring way to defeat him: all party members must have Counterattack or Evade & Counter abilities. The only thing left to do is to use Aim to be sure to hit him, and then just wait for Bahamut to attack and the counterattacks will slowly kill him. The party's HP must be above 25,000 to be sure to survive Dark Bahamut's physical attacks. Also, instead of using a Ribbon you can use an armor that consist of Slowproof, Auto Haste, Stoneproof, and Auto Phoenix or Auto Protect.
Its Overdrive, the famous Mega Flare, is deadly, unless the party has over 40,000 HP. It can be survived by summoning an Aeon or by casting Auto-Life on everyone. It helps if all characters have Strength, Defense, Magic Defense, Accuracy, and Agility at 255. Luck is good at 80 or higher.
As with any other enemy, it can be killed instantly by Yojimbo's Zanmato attack.
