Lunar Bahamut is an optional boss in the iOS and Android versions of Final Fantasy IV: The After Years, the final boss fought before the finale in the Bottommost Depths. It is found inside a chest in the Depths of the True Moon, and a warning is given to the player should they attempt to open it. When beaten, the player is rewarded with the Ultima Weapon.
Lunar Bahamut opens with the traditional countdown from five, with the added twist of being able to countdown by one every time he is attacked, as well as counting down every time he takes a turn; once the timer is up, he will unleash Megaflare on the party, dealing catastrophic damage capable of eliminating the entire team, even at levels as high as 60. He also may use such abilities as Stop, Break, Flare, Quake, Protect, Shell, and Haste in between castings of Megaflare, which is used often as a recurring attack. He may also use Black Hole, which removes all status enhancements to the party; and also Mind Blast, which inflicts paralysis and Sap to the party member. Lunar Bahamut may also use Magic Buster, which greatly reduces the target's MP. After a fatal blow is struck, Lunar Bahamut will cast Meteor on the team before dying.
Cast Protect and Shell if the player wish, but it is of vital importance that the player cast Reflect on as many people they can to negate the damage inflicted by Megaflare and bounces back to Lunar Bahamut. Use Arise and Raise to restore fallen teammates, then commence the assault, hopefully using powerful Bands and spells like Flare and Holy against Lunar Bahamut. Have at least two White Mages present in the fight to keep up the healing effort, and use their abilities to heal not only weakened comrades, but also to dispel any harmful status effects, bolster the team's defense, and to cast Slow on Lunar Bahamut. Before dying, he will use Meteor on the party, which may kill the outright if they aren't at full HP.
Luna means "moon" in Latin, Italian, Romanian, Russian, and Spanish.
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.
