Aqua's Keyblade belongs to Aqua, one of the central protagonists in the upcoming prequel Kingdom Hearts Birth By Sleep. It is known to be able to transform into a bow, either by player command or in certain battles.
Aqua's Keyblade is somewhat similar to the design of Oblivion, with a white and violet colour scheme. The teeth on her Keyblade loosely resembles the crown necklace that Sora wears around his neck. The shaft is very similar to that of the Bond of Flame. The guard is white with jagged silver edges, not connecting to the shaft at the top. The keychain links and token resemble water drops.It is revealed that Aqua can turn her Keyblade into a giant bow and platform and ride it to other worlds like a Gummi Ship.
