Whetton is a character in the One Piece Rainbow Mist filler arc. He is a former pirate, who burned down Ruluka and then became its mayor, because he yearned for safety and power. He later funds Henzo's research, by putting up silly and exorbitant taxes, to complete the construction of the Rainbow Tower, so as to get access to the Rainbow Mist's treasures.
