Bahamut is fought as the final boss of the first part of Final Fantasy XV's multiplayer expansion Comrades during the main quest "The Bladekeeper's Trial". He can be later re-challenged as a superboss.

===Story boss===
Because this is a fight that progresses the game's story, the player has to fight Bahamut without assistance from other players and with preset AI Comrades. Bahamut has a lot of health and uses his sword to hit opponents far from him, but he is slow and leaves himself vulnerable after striking. He has no immunities or resistances to weapons or elements but is immune to certain status aliments, such as Poison and Stop. Bahamut's legs and main body can be targeted, but he may not be broken.
Bahamut is fought in a large circular arena in Angelgard, and slowly hovers towards his current target to attack. He typically attacks by swinging his sword in an arc in front of him, which can be avoided by dodge-rolling, but he may also use a spin attack that covers a large portion of the arena and can hit the player after a roll if they are still close enough due to its long duration. He may also jump-slash towards any target if they are too far away, making any part of the arena dangerous despite its size. If the player attacks Bahamut many times with an aerial attack, he will perform two quick slashes in front of him that knock the player down if not avoided. 
Once the player has depleted half of Bahamut's health, he will begin to use an attack that involves a flurry of slashes ending with a downwards slam. Unlike their speed would suggest, each of the strikes hits for as much damage as the slower ones, but the last hit of the combo may be parried to make Bahamut vulnerable and initiate a chain-warp.
====Strategy====
The player may point-warp to pillars around the rim of the map, making most of Bahamut's attacks miss. Bahamut is not a large difficulty spike from the enemies fought in the preceding hunts in the expansion. During the first battle phase, the player should get used to the timings on his attacks and dodge so they can make the most of his downtime between attacks. One can also focus on avoiding him, and then closing the gap by warp-striking after his attack is over. Bahamut can be interrupted by charge strikes and spells, and he will become vulnerable if enough of these hit him. When he begins to use his strongest attack, a good tactic is to warp away and wait it out, as he will not chase the target much. However, parrying this move requires being right below him, so this strategy misses out on the chance to make him vulnerable.
===Rematch===
In his Level 50 Rematch hunt, Bahamut fights identically to his Main Quest appearance while his HP is above 50%, with the sole difference that he has higher Strength and Vitality and that he begins to use his flurry combo attack at 75% HP instead. He is also fought in the same arena. Unlike his previous battle, the Rematch can be challenged with up to three other players online.
Upon reducing his HP below half, Bahamut will briefly become invulnerable and hover about the center of the arena. He will then transform into his second phase, where he is much faster, gains more attacks, and upgrades existing ones with additional crystalline swords to extend their range and area of effect. For the rest of the battle, Bahamut permanently gains the Tenacious status effect, increasing his attack power.
Bahamut's hovering speed is increased as he wears swords as wings, and his jump and spin attacks become significantly faster, making more of the arena dangerous due to the ease at which he switches targets. Bahamut also becomes much more difficult to stagger and interrupt, reducing the efficacy of charge strikes and spells. His counter to aerial attacks gains the ability to hit targets on the ground, making it hazardous to other players who are not also in the air. However, he loses his ability to do the extended flurry combo.
While above 25% of his HP, Bahamut will often fly high above the center of the arena and then plummet, making a ring of swords that expands from the center and then retracts, covering all of the arena. This attack often downs the AI Comrades, and if the player is hit right below Bahamut, they will take massive Max HP damage. This attack can be parried, although using a Mace to do so will not cause Bahamut to become vulnerable due to a glitch.
When he drops below 25% HP, this attack will also be upgraded into an attack resembling Ultima Sword or Megaflare, which is his strongest attack in both damage and area. When he flies up, swords will rain down on fixed spots on the arena and create a maze. The swords then vanish briefly and Bahamut slams down, causing a spiral of pillars of light to emerge from the middle, which deal massive Maximum HP damage to those they hit, likely crippling unprepared players. This attack can likewise be parried, although one needs to slip in below Bahamut in the brief moment between the swords' disappearance and his plummeting. When Bahamut uses this attack for the first time, all point-warp spots on the arena will be destroyed.
The player gains the ability to challenge the "Dastardly Duo" bonus quest upon beating this boss.
====Strategy====
For the first phase of the battle, the same strategy as the first fight can be used, although the player must be wary of Bahamut's higher stats and also to not lose too much HP in preparation for the second phase.
For the second phase, directly dodging Bahamut's attacks becomes essential as being far away from him for long is very difficult due to his increased mobility and range. Therefore, learning timings for dodge-rolling, not only his sword but his additional swords, is crucial. Using more offensive sigils, like Aerial Ace or Aura, can increase the player's damage output to match his, but more defensive sigils, like Untouchable and Dragoon Drain, can increase survivability. However, he tends to use parriable attacks more often in this fight, which can be punished through Chain-Warps, making this hunt not so difficult if one can consistently get below him and defend.
===Final Round===
The Level 99 Final Round hunt has much greater stats than the Rematch version at one million HP and over a thousand spirit, making magic spells less effective against him and ensuring the fight is much more drawn out. In addition to this, Bahamut transforms to his second phase at 90% HP instead of 50%, and has differences in his behavior that make the superboss much more challenging than his previous iteration. The point-warp pillars in the arena will also be destroyed as soon as he transforms, making MP management more important.
Bahamut will randomly cycle between certain powerful attacks which he uses between his regular onslaught. These include the sword ring parriable attack from the previous fight, but also include two new ones, making the former rarer. One of them is identical to the sword ring in setup, with Bahamut flying to the middle of the stage, but arranges his swords in a different pattern. This attack forms a cage of swords around Bahamut and cannot be blocked or parried once he slams down, dealing massive maximum HP damage to the player if they are caught in it. The second is a sword rain attack, which launches a barrage of homing swords that do minimal max HP damage but can trap the player due to their sheer quantity. Bahamut hovers around the arena in a circle while using this attack, and it must be dodged as he will only exit this stance once enough time has elapsed. Because this kind of attack is not used frequently by Bahamut, unlike Rematch where they are seen often, the player has very few opportunities to parry him for most part of the battle.
Once Bahamut drops to below 50% HP, he gains two new attacks that are much stronger than his regular attacks and also much more difficult to avoid, including a multi-hit combo, with crystalline swords serving as a very large hitbox that is difficult to escape even with dodge-rolling, and the arena-sweeping Divebomb attack that deals the most damage out of his unparriable attacks, likely killing players with vitality stats below 2000 in one hit. Bahamut can chain many Divebombs in a row, and he can loop back to strike twice in a single dive. In between these attacks, Bahamut begins to swiftly leap around the arena even when not attacking, making opportunities to strike him rarer. He will begin using his ultimate attack below 25% HP, as usual, and it works the same as his previous fight, only dealing even more damage. 
The player gains the ability to create a character with the Gralea birthplace upon beating this superboss.
====Strategy====
Bahamut's Final Round is one of the hardest battles in all of Comrades, and the player should bring the best possible gear. Melee-oriented sigils like Aerial Ace and Aura are highly advised to bring him down quickly, as the player can only die once and Bahamut has lots of HP. This fight puts greater emphasis on evasion than parrying, as his parriable attacks are rarer than Rematch, so dodge roll timings are even more important. With the Aerial Ace sigil, the player can tap block midair as an attack is about to hit them to airslip through it, while a Dragoon Drain user can employ Jump to avoid all damage while it is active. In terms of new attacks, Bahamut's sword rain can be avoided by spamming free warps with a fast weapon like Daggers, and his Divebomb can be avoided by dodge-rolling at the right moment, but his multi-hit combo is much trickier in terms of timing and is better avoided altogether by warping away.
