I have seen some awesome examples of Dark Sandman and Light Pitch. I just love the different interpretations people have made! But since I’m an idiot, the thing that came to my mind when I looked through all those awesome works was “What if it was nothing but a body change?” I think it would be a bit weird for both of them… For different reasons..
I know they still have their colours but I figured Sandy’s clothes are made of sand and Pitch’s robe is made of… Ink? I don’t know but they could keep their colours!
