The one on the top is thlax. Origin of thlax- he went in a dark cave and saw a button that said you need to follow ratyu. but he didn’t know who that was and pressed it anyway and when he looked at his hand pure darkness. So when he ran home and looked in the mirror he saw it. His body was black and at the left top of his head white and a voice grew over the silence. The one on the bottom is David. thlax is the one who was the white side of davids body and david was the black side. The multi colored character is just some regular dude with different colors and is the balance of color. Hoped you liked the story lol
