3-DUVAL
Duval is a very large man who was originally introduced wearing a large iron mask, with long red tufts attached to it, giving him his epithet Iron Mask Duval.
2-KING THE WILDFIRE
King wears mostly dark clothes that completely cover his body, including a mask over his face and a spiked hat with goggles on it. Flames also appear to be emitting from the back of his head.
1-SOGEKING
Sogeking is Usopp’s alter-ego that he developed during the Water 7 and Enies Lobby Arcs after he left the crew. He hastily disguised himself in a mask and cape and began calling himself “Sogeking”. Sogeking’s trademark mask is from the Sea Train Puffing Tom: as Sanji leaves the last car of the Sea Train, the mask is visible sitting in an open suitcase. It was probably left over from the mask festival that was taking place on a nearby island at the time. The Sogeking costume is only complete when Usopp incorporates his favorite goggles into the mask’s eye holes.
