—Caius when he transforms into Chaos Bahamut

Chaos Bahamut appears in Final Fantasy XIII-2 as a boss. It is an Eidolon incarnated by Caius Ballad. It first appears in the pregame tutorial, and later as a boss. Chaos Bahamut is considerably weaker in comparison to the three other Bahamuts that appear in the game, Amber Bahamut, Garnet Bahamut, and Jet Bahamut.

Chaos Bahamut's main appearance is at the end of Academia 500 AF.

Chaos Bahamut is also fought in the DLC episode Requiem of the Goddess.

Valhalla -??? AF- (prologue)Edit

When Chaos Bahamut's HP has dropped to 50%, a cutscene will occur. The player must continue to fight until another cinematic action occurs.

The second battle is still simple, but Chaos Bahamut's moves have changed since the first battle. War's Benediction can be used to heal and it also grants the Haste status.

Megaflare can do major damage and Chaos Bahamut's moves that prevent the player from attacking it. During the battle, a cutscene will play but the player must continue fighting until his HP has dropped to zero.


It is recommended to use Lightning Strike to fill up the ATB gauge, as well as watching out for Chaos Bahamut's attacks. Ullr's Shield can be used to heal and gain two status boosts: Protect and Shell.

Using Graviton Cores will allow the player to fill up the ATB bar and attack.

Academia -500 AF-Edit

Chaos Bahamut has two forms. At first he simply hovers before using Metamorphosis, upon which he becomes a flying mechanical wyvern. In its normal form, it will use potentially crippling physical attacks to beat down the party in sets of two. After a small amount of time of using these attacks, he will change between forms and begin to use powerful magic attacks instead, such as Megaflare, which causes a large amount of non-elemental damage with a side effect of wounding the party.

Chaos Bahamut is immune to the Sentinel's Provoke ability but is susceptible to three debuffs: Deprotect, Deshell, and Imperil.


The best way to counter Chaos Bahamut's onslaught of powerful attacks is to use the all-Sentinel paradigm, Tortoise, to minimize Megaflare's effect. As Chaos Bahamut is immune to the Sentinel's Provoke the player will have to heal more often. Unless the party is fairly strong, it will be a good idea to have a Sentinel in all paradigms to minimize damage over a wide area.

It is recommended a good Medic is in at least one paradigm. Since Chaos Bahamut is susceptible to some debuffs a good Saboteur can take advantage of this weakness. Once the party boosts its chain bonus up significantly, Chaos Bahamut shouldn't take long to defeat.

Lightning Chaos Bahamut RotG

Caius transformed into Chaos Bahamut.

If the player defeats Caius fast enough in "Requiem of the Goddess", Caius transforms into Chaos Bahamut and is fought in that form.

Chaos Bahamut has the same abilities he has in his other battles, but in addition can use Resist Wind and Resist Lightning to change his vulnerabilities. When using Resist Wind, he will become invulnerable to Wind and physical attacks, and with Resist Lightning, will become immune to Lightning and magic attacks.

The battle starts with Chaos Bahamut being in his normal form where he uses physical attacks and Whirlwind, Ignis, and Umbral Vise. After a while he transforms into his aerial form where his abilities vary depending on which resist is currently on. If he is under Resist Wind, he attacks only with Pulsar Burst, and if under Resist Lightning, he will only attack with Obliterating Breath. After being in aerial mode for a while he will use Megaflare and switch back to normal form and cycle will begin anew.

Defeating the DLC's Chaos Bahamut with a five star rank with Lightning's level at 9 or lower nets Lightning in her Knight of Etro armor as a Paradigm Pack ally.


Chaos Bahamut changing his properties forces the player to use Mage and Shaman roles accordingly, because Mage uses Lightning-based magic attacks only and Shaman uses only Wind-based physical attacks.

The key to victory is to pay close attention on his Resist-ability and use the correct role to drive up his chain gauge. Same applies when using Paladin. Ruin should be used when under Resist Wind and Attack when under Resist Lightning. When he switches to aerial form, it's important to keep an eye out for Megaflare, and when he is about to launch it, the player must quickly switch to Knight and use Immortality to survive.



Chaos is "the formless matter supposed to have existed before the creation of the universe."

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.


  • In the aerial fight between Lightning and Caius at the beginning of the game, sound designer Tomohiro Yajima overlapped the sounds made in the sky and automatically calculated the weight of the sound as objects pass to bring out the scene's presence and flashiness.[1]
