Bone Crusher

Known Information
Obviously his name is known and height but that is where it gets complicated. When spotted he makes himself as big as possible and he grows horns this stops anyone from seeing any of his other formations and his human self.

Rivalry
although he has the same powers as Bone Smasher, he is more powerful than him because he gained his powers in a different way. All that is known is that every time the two of them meet it is so obvious that Bone Smasher is so much smarter.
