This is Blank, yes both of them. See how he has that ring that has electricity coming out of it around him at the bottom and hand(ring 1: right, ring 2: left)? Well he's changing. The picture on the left were he is all white with a little bit of shading on him and coming out of his hand is that ring, he's holding that rock. that rock is making him turn to rock. Blank can touch almost anything and turn into it.
