Matrix

White parts are ghostly; black bones in chest and tail, legs are pure ghost-like

Multiple faces but one consciousness. He’s one being. The outer heads, however, do have a strange vibe and appear to be sentient still?

His middle head’s eye can shift around his face, but the outer heads’ eyes do not move around.

His heads often glitch out when angered.

He can jump through dimensions and teleport, and is prone to causing, well, glitches in the matrix because of this. It’s a “stain” from his warping/teleporting. 

Matrix is very intelligent, and knows the answers to endless questions, but he will not share them. He may, however, guide others to the way of finding these answers (if he feels “nice” that day). His guidance is not easy to follow, though, and will lead the ones who follow him into a tedious future. (It’s better if you don’t mess with him..)

If you choose to follow Matrix and his riddles and fail, he will consume your soul, but leave your consciousness as a husk.
