Kage-Shin

Kage-shin are an ancient species that are a species when a Heartless and Nobody merge into one, but unlike what many believed would regain their original selves, is in fact a higher form of their evolution. Some believe they are far mroe advanced and more powerful as a Keyblader. However it was said to be unheard of and thought to be impossible to for such creatures to evolve further and believed to have been 'extinct' since the last war which was over a thousand years ago.

Appearance
The Kage-shin are the result of a Heartless and Nobody merge into one being.

come in varied forms of appearances; shape, form and size. Although they would regain most of their natural selfs once sealing their true forms inside their weapons.

Powers & Abilities
Like Keybladers, the Kage-shin have a multitude of combat skills and abilities, some of which are also similiar to the late members of the Organization XIII, nobodies and Heartless. It is possible they have similiarities from other races in their time to reach a higher level of their evolution.
