The summon Bahamut is primarily seen in the Final Fantasy series of video games. It was also planned to make an appearance in the Kingdom Hearts series as well.
Bahamut the Dragon King is an important character in Final Fantasy. He upgrades your party's classes if you have the Rat's Tail from the Citadel of Trials, strengthening your party and granting you access to more better equipment in the game.
Final Fantasy 10, 10-2 and 12 were for the PS2.
He is a 'Fayth', a summoner preserved in stone. The Aeons themselves are dreamed into existence by the Fayth, that boy is Bahamut's Fayth.
Get to Hellfire Chasm by warping into one of the holes on the islands full of holes (the same are where you enter to upgrade your characters with the dragon Bahamut).
