Synch Blade

Synch Blade is an ability which allows a Keyblade wielder to summon another Keyblade during battle. So far, the only characters to use this are Roxas, who can use this ability to summon his two Keyblades, the Oathkeeper & Oblivion, and Sora while in Valor Form, Master Form, and Final Form.

Roxas gained the ability to use Synch Blade after defeating Xion, giving him the ability to wield both Keyblades. They are both technically Sora's keyblades, and Roxas possesses all of his abilities, so the Keyblades are his to use as well.
