Lunar Bahamut is an optional boss in the Game Boy Advance and Playstation Portable ports of Final Fantasy IV. It is fought during Kain Highwind's Lunar Trial at the Lunar Ruins. When beaten, the player obtains the Dragoon Gloves, which boost Kain's stats and changes his Jump command to Double Jump, the Abel's Lance, and the Grimoire LB, which, if used as an item, summons Lunar Bahamut to deal 9,999 damage to all enemies. Using up the Grimoire unlocks the trial door again. Defeating Lunar Bahamut a second time nets the player a Megalixir.
