in this role: Shadow gave birth ('cause Infinite rape him) The Thing (the things that are in Sonic forces, the tallest creatures that are kinda like Infinite) well, Infinte said to Shadow that when they'll big, they will take no orders from noone and he have to use the ruby to control them. So, Shadow take the ruby from him and use it but he change, he has alien blood so this "true" form when he use it but his personality also change a littler, thats make Sonic care about Shadow.
