Omega (Final Fantasy V)

Omega Weapon (simplified as Omega), is one of the two "super bosses" in Final Fantasy V. It is a machine and found in the Interdimensional Rift directly after the save point. It is a rare monster that is visible on the world map, so it can be avoided. It has incredible defense and has a very high chance of evading incoming attacks. In fact, it is doubtful that you will do any damage at all with normal physical attacks. It requires a specific strategy to beat that must be followed to the letter, or Omega will wipe you out. It has two special attacks, called Rocket Punch and Encircle. Rocket Punch reduces your HP by half and causes confuse, while Encircle wipes out the party member for the duration of the battle. A victim of Encircle cannot be revived by a Phoenix Down or Raise. It has 55,530 HP, gives you 50,000 gil for defeating it, has a strength stat of 115, a defense stat of 190, and is weak versus Lightning. Also, Omega is protected by Reflect, so direct spells will be sent right back.

There is a upgraded version of Omega titled Omega Mk.II which serves as the boss for the optional dungeon called the Tomb of Memory.
