The Undying is the final boss of Final Fantasy XII. It is the final form that Vayne takes by merging with Venat and assimilating components of the Sky Fortress Bahamut into his body. This form is draconic, as the Sky Fortress's namesake is the recurring dragon summon Bahamut.

Defeating The Undying in The Zodiac Age awards the "Wings of My Own" trophy/achievement.

Battle with The Undying.

The Undying has no life bar, so the only way to know how much health he has is to know his AI script, and when he starts flashing red when in HP Critical. There is no indicator line to whom the boss is targeting, but The Undying tends to attack those near to it.

In his first form, The Undying mostly casts Piercing Firaga, Piercing Blizzaga, and Piercing Thundaga. His strongest magick, Megaflare, hits over 3,000 damage. When he uses his first special attack, Ascension, he will change his strategy and focus on using his "arm cannon", which hits about 2,000 and above per hit. The "arm cannon" is a gun-type attack, which means it ignores Defense. If the characters buff in his firing range, The Undying will cast Piercing Dispelga on the party member with the most buffs.

The Undying will build a Magick Barrier, which negates all magick thrown at him. In low health, The Undying will use Perfect Defense, negating all physical and magickal attacks. The Undying will buff himself and use Gigaflare Sword, which can cause up to 5,800 damage. Just as his defenses fade, The Undying readies his last special attack, Tera Flare, which hits upward of 4,000 damage.


Piercing Dispelga.

Because of The Undying's Piercing Dispelga, only the most important buffs, such as Haste, should be used. During The Undying's first form Shell is useful. The party may be unable to do anything to him when The Undying has a paling (e.g. the ones who cannot cast Balance); their time can be used to heal or buff the party with Shell, Haste, Regen and Bubble, but one must be out of range of Piercing Dispelga when casting the buffs.

When his HP is depleted 75%, The Undying will heal, giving the player the chance to deal massive damage by attacking him head on. When he is flashing red, his Defense increases. The Gil Toss Technick is useful, for if the player has 10,000+ gil, it will deal 9,999 damage per hit.

Musical theme[]

The final boss theme is "Struggle for Freedom". It features a medley of the other boss themes, as well as a continuous riff of the "The Archadian Empire" and the main theme of Final Fantasy XII, representing the two motifs struggling against each other. The theme was composed by Hitoshi Sakimoto.

Behind the scenes[]


The Undying's special moves—Megaflare, Gigaflare (Sword) and Teraflare—are signature moves of Bahamut's different forms from the series: Megaflare is used by Bahamut, Gigaflare is used by Neo Bahamut, and Teraflare is used by Bahamut ZERO.

The orbiting or "strafing" of his winged form around the edge of the circular platform is a tribute to the final boss battle with Romeo Guildenstern's final form in Vagrant Story, another tale by Yasumi Matsuno.



The boss is called the Undying, a name the Occuria use for themselves, beings who deem themselves immortal and thus the rightful rulers of Ivalice. Vayne becomes the Undying after merging with Venat, the rogue Occuria, but the name is ironic as Vayne and Venat's lines before merging imply that they know they will die doing this. Vayne tells Venat that "he failed them both", that he's "no Dynast-King", and Venat needs to "find some other, one who might realize your ambitions". Venat replies: "They are fulfilled behind your knowing. The Sun-Cryst is shattered. Age of Stones complete. From the Undying ones the world is freed. You shall not walk this path alone, together we go. Come." "This path" is assumed to mean death.
