Omega is a floor boss in the optional dungeon, Infinity Spire in Final Fantasy Crystal Chronicles: My Life as a King. He uses an attack called Wave Cannon that will hit every Adventurer that is inside Infinity Spire, even if they are not fighting him. Defeating Omega rewards one of the Adventurers who survived the battle with the Omega Symbol, a level 50 necklace that adds +27 to all stats.
