Ready when you are!Fang
Bahamut is a boss in Final Fantasy XIII and Final Fantasy XIII-2. He is Fang's Eidolon, and is fought in the Fifth Ark by Fang, Lightning, and Vanille, as a test to prove Fang's strength to him. Bahamut is a mechanical dragon who stands on two legs and uses his enormous claws to attack.
While the group discusses whether they should carry out their Focus to destroy Cocoon, or if they should follow Serah's last words of saving it, Fang pulls her weapon against the party, making it clear she would rather destroy Cocoon than see her friends become Cie'th. From her rage, Bahamut is summoned. Fang states that the Eidolons appear whenever a l'Cie's path towards completing their Focus begins to waver, forcing the l'Cie to choose life or death.
Bahamut inflicts Doom on Fang at the beginning of the battle, and instead of defeating him, the player must fill Bahamut's Gestalt Bar. Bahamut is an aggressive Eidolon, initially targeting Fang with physical attacks followed by Whirlwind on the party. Libra will reveal that hitting him to get chain bonuses and switching to Saboteur to debuff him will satisfy him, as well as defending the party as a Sentinel.
Good paradigm sets for the battle are Safe Subversion (SAB/SAB/MED) and Perseverance (SAB/MED/MED). Saboteur fills up Bahamut's Gestalt Bar quickly. Other good ones are Combat Clinic (SEN/MED/MED) for healing and Mystic Tower (SEN/RAV/RAV) for attacking. The party should look out for his Whirlwind>Umbral Vise>Ignis combo.
Other appearances Edit
Bahamut appears as an enemy.
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.
