Clan Primer
Genus: Unclassified

Classification: Ancient Warmech

''An ancient weapon of war, traveling the rifts between dimensions. Its body is set with machineries and weaponry of a far higher order than anything made today. Though it is a construct, it was built with the ability to grow, and so it has evolved like a living creature.''

It generates the energy it needs to live by filtering and condensing Mist from the air.

Location
Omega is located in the Great Crystal at Giruvegan and is only available to fight once the Elite Mark for Yiazmat has been accepted. The player party can enter Omega's chamber in the Crystal beforehand, but it will be in a dormant state and unresponsive, resembling a giant treasure chest like the Mimics in Barheim Passage.

Rewards
Following defeat, Omega will drop the Omega Badge key item. Selling the Omega Badge, Godslayer's Badge and Lu Shang's Badge will unlock the ultimate weapon in the Bazaar, the Wyrmhero Blade.

The Final Fantasy XII Scenario Ultimania also revealed that the Mythril Sword, an item not obtainable through shops, loots, or treasure chests can be obtained from defeating Omega. The important thing to do is to raise the Chain Level to its highest level just before attacking Omega.

Battle
This battle is going to be tough. He will continuously use a laser beam and kill you in two hits, even if you are level 99. Use Balance if your HP is low. You should have Arise, Renew,and Curaja. Hit him hard and revive when needed. Another suggested option that is viable at any level is to get three decoy characters under stop and reverse, a primary mage, a vanished character, and the character who controls Zodiark. First get your Zodiark character under reverse, and approach Omega on the platform. Summon Zodiark, who will use Final Eclipse. After that dump one of your decoys on the platform (leaving the Zodiark character K'Oed) and put in your vanish character, who will try to sneak away and revive the Zodiark character, also putting him under reverse. Then, remove all characters from play and you will go to your stopped decoy who keeps Omega busy. Put in the character who controls Zodiark and do Final Eclipse again. If stop runs out dump in another decoy, revive the fallen one and put him under stop and reverse again. The idea is to repeat this action, using Final Eclipse 20-30 times or so, until Omega falls. The key is keeping the decoy on the platform with omega, so it stays busy and doesn't restore itself. Additionally, casting Vanish on the party will make Omega unable to see them, making the fight considerably easier.

Another simpler tactic is to, with Bubble Belts equipped, use the following gambits in this order: (1) Self = Reverse; (2) Any Ally = Arise; and (3) Attack nearest target. Once in a while, cast Hastega after a party member has cast Reverse on him/herself. Make sure that you do not run low on MP, and Omega will fall in no time.

Ancient Warmech
According to the Clan Primer entry, Omega Mk. XII is a construct of machine and weaponry that was created to battle a great Wyrm, possibly the Hell Wyrm or Yiazmat. This could also be a reference to Shinryu, if it truly is the same Omega from previous games. Omega was also given the ability to grow and evolve. It was left in the Great Crystal and allowed to grow on its own, using the Mist as an energy source. The story from the Urutan-Yensa bestiary entry seems to tell of the creation of Omega Mark XII, and implies that the creator lost track of it after its tracking devices were destroyed in a battle of some sort.

Version Differences
In the Japanese version of Final Fantasy XII, Omega has a little more than 10 Million HP, making him second only to Yiazmat. But for the North American and PAL versions, it's HP was reduced to a mere 1 Million, less than the Hell Wyrm and even a couple of the higher Marks. The North American and PAL versions of Omega also added the berserk status effect onto Omega's attack. Whatever the reasons for this change, Omega is still one of the toughest battles, being the only enemy at Level 99 with the highest strength, defense and magic power.
