It started out as just a plain and simple weapon in the first Kingdom Hearts game, but then in KH: Birth by Sleep, it began to become much more as it took the shape of a vehicle. In the most recent trailer for Kingdom Hearts III, it was shown that the Keyblade can transform into even more extraordinary objects, one of these being a gun. Nomura has teased about maybe having more transformations in the future. What would you like to see as a transformation for the Keyblade?
Kingdom Hearts III is currently in development for PlayStation 4 and Xbox One.
