Bahamut also known as The Dragon King is a character in Final Fantasy Brave Exvius and member of Hess' Eight Sages. He's known as the strongest of all Espers and can be recruited as such nearing the end of Season One. He debuts in the Zoldaad chapter.
Bahamut is a large black, draconian monster. He has a more humanoid shape following more recent depictions of the Esper, rather than his more classic, serpentine appearance.
Bahamut was an Esper in the world of Paladia being known as the strongest of his kin. When war erupted between Aldore and Hess for the latter's independence, Hess' army was considered the weakest but was successful in recruiting a vast number of Espers to their side, including the Dragon King himself. Because of his power, Bahamut was given the rank of Sage, although it is not known whether Bahamut joined after many Espers did so, or Bahamut somehow coerced his comrades to join Hess.
As the war dragged on and casualties were increasing on both sides, the first Veritas of the Dark decided to end the war by sealing the Sages into Crystals and along the Sworn Eight of Paladia, become the leverage power in order to force negotiations to allow Hess' independence. The sealing succeed and Bahamut was defeated and sealed into the Fire Crystal. However the leaders of Aldore, fearful of their lieutenants, betrayed them by forcing the landmass of the battlefield to be transported to Lapis expelling a significant amount of people to another world. The Sages' themselves were by proxy also transported.
Bahamut remained dormant for 700 years in the Fire Crystal and eventually under the possession of the Zoldaad Empire who would use the Crystals power to increase their military might.
When Rain and his friends are successful in repelling Veritas of the Dark and Veritas of the Flame and protect the Fire Crystal from them, Jake deciding to prioritize his people's safety, destroys the Crystal to weaken the Empire. This act releases the Dragon King, whom Fina is able to sense although barely remember. Although the party chastises Jake for his decision, he stands by his choice as he believes the Empire to be a more imminent threat than Bahamut is at the moment.
When Rain and his friends defeat Sozhe, and pursue Dr. Lazarov who manages to get into The Invincible, the mad scientist attempts to use the airship against them. However Bahamut senses Babil's Heart inside and challenges the Airship, blasting it with a Megaflare and causing enough damage to force Lazarov to hide and repair it.
Bahamut flies away afterwards, but his strength would be able to project a Vision of him that Rain and his friends would eventually encounter.
Bahamut is the strongest Esper found in the game, even at 1★ his strength surpasses that of Espers in their higher levels. He takes much longer to level up than other Espers and has no preference for any kind of Magicite. He is, however, highly sought as he vastly increases all Stats when equipped and his Megaflare Summon Attack is strong enough to deal massive damage, especially when capping it on a high chain count.
Bahamut is fought near the end of Season One in an optional Boss Fight on his own dungeon. His battle plays similarly to the Vision of Bahamut event, although with much higher difficulty, with increased HP, increased damage, and more diverse and tricky skill set.
- He's currently the only member of Hess' Eight Sages who is an optional Boss Fight.
