Ultima Buster can be unlocked in the Monster Arena by capturing five of each fiend across all of Spira.
Ultima Buster has a number of attacks that will hit your party members with negative status effects. Its “Contamination” attack will inflict Confuse, Poison, Slow, Zombie and Full Break.
You should consider power leveling your characters and obtaining the Celestial Weapons. Check out the Advanced section of the Tips and Tricks for more information. Properly leveled characters with their strongest weapons is a necessity for this battle.
You should also consider crafting strong armor that contains the 
Ribbon accessory among others. Check out the Best Armor section for additional details.
Using spells that hit the head, the arms and the body all at the same time are incredibly effective. This includes spells like 
Ultima. Alternatively, you can have Yuna summon her Aeons to assist with the battle.
