Unforgivable Mask

Unforgivable Mask is a hidden One Piece character, much like Pandaman. He is in fact, Pandaman's rival.

Appearance
His appearance is that of a muscle bounded figure with a panda face as a mask. He wears black speedos and boots.

History
He is seen in Color Walk 2 and also under the dust jacket of Volume 46 inside the snake's mouth. He was hired by Tomato Gang to track down Pandaman. An interesting fact: unlike Pandaman (and others with a similar style), who appears to have a Panda's head, Unforgivable Mask actually appears to be wearing a mask.
