You can get Bahamut when you have access to the Ragnarok on disk 3. Fly to the Deep Sea Research centre (line up the point where the tip of the island closest to hell meets Edea’s house if you drew a straight line). Land the Ragnarok, then enter. Walk towards the blue core in the middle of the room but stop when the blue light pulses, not doing so will cause you to enter a battle with Anacondaur’s and Blood Souls (encounter none/half don’t work btw).
Once you reach the core a voice will appear and you will be given an option of what to say, choose the only option “It is not our will to fight”. You will enter a battle with a ruby dragon, use Quistis to degenerator it or smash it with other limit breaks. Once defeated you will be given another option, select “Never”; another battle with a ruby dragon will ensue. Defeat it and you will be asked a third and final question, select the third answer (it’s hidden – blank), after a bit more dialog you will fight the big boy himself, Bahamut.
Some people find him tough so make sure your junctions are up to scratch and have some good ability’s junctioned(HP+80, STR+60 etc). Irvine,s AP ammo works a treat as well as Zell’s combos and Squall’s Renzokuken. Cast meltdown for extra effectiveness.
Once defeated he will join your party and you get his card.
