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 and Oblivion, and Sora while in Valor Form, Master Form, and Final Form.

Roxas can use Synch Blade because he has both Sora's Keyblade and Ventus's Keyblade, due to Ventus's heart remaining within him. Originally, he just wields Sora's Keyblade, as Xion's creation had siphoned away Ventus's Keyblade. However, when she is defeated, his powers return to him, and he reawakens the ability to use Ventus's Keyblade. After Sora and Roxas come back together, Sora is able to mimic Roxas's Synch Blade within several of his Drive Forms, but since Sora possesses every ability that Roxas had, it is also possible for Sora to use Synch Blade naturally, without going into a Drive Form.
