Dolomite was originally a handsome man. Wearing an undercut, the hair on his sides was shaved down whilst the hair on his crown was pulled to the right of his forehead. He wore an exotic striped jacket over a dark, long-sleeved shirt.

After his body was destroyed, Dolomite's appearance drastically changed. His entire body and skin took on a more rock-like appearance, with a rougher complexion and cracks in his skin. Dolomite's arms and legs are reduced to stumps while his teeth are broken and cracked. His eyes are duller and a strange marking exists above his nose, in the form of a triangle with a small circle above it. His hair has grown out much longer and is unkempt, hanging over his shoulders. As for clothing, he still retains his exotic jacket but nothing else.
