Omega Weapon



The Omega Weapon (オメガウェポン) is a form of the Keyblade obtained when the Pandora's Gear is equipped. It can only be wielded by Roxas and Xion in Kingdom Hearts 358/2 Days. With the absence of Ultima Weapon, this Keyblade fills the role as one of the strongest weapons in the game. An upgraded version, the Omega Weapon+ also exists.

Design
Like almost all weapons transformed by Pandora's Gear, the color scheme of Omega Weapon consists of gold, silver, red and black. Its design matches with Ultima Weapon, which appears to be a redesigned sword and also keeping with the heart symbol theme as seen above the hilt, including the keychain token.

Gameplay
All of Omega Weapon's passive abilities are connected to the player's HP. Having a full HP Bar will cause the Omega Weapon to deal more damage to enemies and make them stagger with each hit. A full HP Bar also reduces the damage taken by the enemy down to ⅓ of the usual. For the ground combo, it starts with a hard forward strike, a knock in the air and a midair hit. Pressing Y will cause a downward slash to the ground. For the aerial combo, it causes a backflip and later a frontal hit.
