Omega Weapon



The Omega Weapon (オメガウェポン) is a form of the Kingdom Key that is changed into the Omega Weapon with the Pandora Gear equipped. Omega Weapon is, in all-around terms, the most powerful weapon Roxas or Xion can use.

Its A+A+A+A+A combo makes Roxas/Xion make a powerful thrust, then a strong downward hit, then an upper hit, then they jump to make an aerial attack, and finally to finish with an incredibly powerful lander.

Trivia
The Omega Weapon is a recurring superboss in the Final Fantasy series that is usually connected to the Ultima Weapon, providing an analogy to Sora's Ultima Weapon.
