Template:FFX Enemies Nemesis (Italian: "Il Supremo" lit. The Supreme) is a secret fiend in Final Fantasy X that is created by the old man who runs the Monster Arena in the Calm Lands. Nemesis looks similar to Omega Weapon, and Ultima Weapon. Often nicknamed Omega Gold, it is the most durable and most challenging enemy in the game (with the exception of Penance in the PAL and International versions of the game), with nearly 10,000,000 Hit Points and an array of spells and attacks that can instantly kill even the highest-level, best-equipped parties.
Strategy
To unlock this battle you have to capture 10 of every capturable fiend and defeat all the other creations in the Monster Arena.
Overdrives cause Nemesis to counter with Ultima, dealing a large amount of damage to all party members. His Ethereal Cannon is a non-elemental magic-based attack against one character; and Ultra Spark will inflict many status ailments including Curse and Power Break on the party. Nemesis' ultimate attack is Armageddon, which hits all characters for 99,999 damage every time. The latter is graphically identical to Omega Weapon's Nova.
Following defeat, Nemesis will drop weapons with Break Damage Limit or armor with Break HP Limit abilities and two or three empty expansion slots.
Once it is defeated you will receive the coveted Key Item, Mark of Conquest. Despite the kudos that come along with such an item, Nemesis can be fought an unlimited amount of times provided the player has enough Gil.
Additionally, if a player missed Kimahri's Nova Overdrive from Omega Weapon, it can be acquired from this boss.
