Synch Blade

Roxas uses Synch Blade in his battle against Axel in Kingdom Hearts II.

Synch Blade (シンクロブレード Shinkuro Burēdo?, lit. "Synchro Blade") is an ability that appears in Kingdom Hearts II. It allows the user to summon a second Keyblade during battle. So far, the only characters to use this are Roxas, who can use this ability to wield his twin Keyblades Oathkeeper & Oblivion, and Sora while in Valor Form, Master Form, and Final Form as well as Double Form.


Kingdom Hearts II[edit]

Roxas can use two Keyblades at once because he has both Sora and Ventus's Keyblades, due to Ventus's heart remaining within him when Sora became a Heartless.[1] Originally, he can only wield Sora's Keyblade, but when Xion is defeated, he reawakens the ability to use Ventus's Keyblade.[2] After Sora and Roxas reunite, Sora is able to use Synch Blade within Valor, Master, and Final Form, but since Sora possesses every ability that Roxas had,[3][?] it is theoretically possible for Sora to use Synch Blade naturally, without going into a Drive Form.[citation needed]


In Kingdom Hearts II, Synch Blade is a support ability. It grants the user access to the abilities of both of their weapons.

Notes and references[edit]

  1. ^ Kingdom Hearts Birth by Sleep Ultimania, Interviewer: "Is it possible that Roxas has a heart?" / Tetsuya Nomura: "It is thought that it could be Ventus’ heart... As was said in Q1, he has taken a lot of himself from Ventus. But perhaps when Sora and Roxas were separated, Ventus’ heart stayed in Roxas?" Translation via Lissar.
  2. ^ Kingdom Hearts Birth by Sleep Ultimania, p. 617; Interviewer: "Why can Roxas dual-wield?" / Tetsuya Nomura: "Sora can wield two Keyblades at once because he has Ventus's as well as his own. As Roxas is a part of Sora, he also can use two. In Days, Roxas awakened his ability to dual wield after fighting Xion. In KHII, once Sora absorbs him, he can also dual-wield." Translation via Lissar.
