Unforgivable Mask

Unforgivable Mask is a hidden One Piece character like Pandaman. He is in fact, Pandaman's rival. He is seen in colour walk 2 and also under the dusk cover of volume 46 inside the snake's mouth. He was hired by the 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 appears to be actually wearing a mask.
