Two Become One

The Two Across Keyblade is obtained after defeating Roxas in Kingdom Hearts II: Final Mix . This Keyblade, along with the Winner's Proof Keyblade are Final Mix+ exclusives. Its Keychain motif is Roxas' zipper symbol, which is based on the 'spike' motif found in every Organization XIII member's weapon.

The ability of this weapon makes it so that when equipped, going into any Drive form (with the exception of Final Form) will result in Sora Driving into either Anti Form or Final Form, with Final Form becoming more likely with each Drive into Anti Form.
