Waterborn

Waterborn is a weapon used by Allen Trius in Kingdom Hearts: Awakening. It is his default sword, and can change into a Keyblade.

Design
Waterborn appears to be a normal sword. It has a curve in the blade at the end, and is of medium length. It's hilt is attached to the blade by a mechanism built for easier grip, and it has a red cloth attached to is.

Strangely, the blade always seems to be swirling with water.
