Boi got finally a ref, after 3 years of existing, some facts:

-is a shapeshifting shadow being.
-the heartless symbol he adopted after his favorite game.
-can turn into most of the characters I own, is practically those characters and has given them their own personality and developed some abilities with some.
-he tends to take the form that seems to fit best with the current people and situation.
-excluded of this are: Seras the Kitsune (will add more as time goes on)
-can copy other people, but just visually, not vocally or ability wise.
-is non-binary but sees himself as male.
-doesn't have a mouth, his voice sounds echoey like if you'd talk into an empty room.
-has autism but you wouldn't guess from just talking to him.
-prefers to stay 'in character' rather than showing his true form, except close friends.
-the wisps of darkness are NOT optional, he does tend to expel darkness.
