The Monstrous Helmaroc King (大怪鳥ジークロック Dai Kaitori Jīku Rokku?, Big Dubious Bird Siege Roc) is a boss from The Legend of Zelda: The Wind Waker. He is an exceptionally large Kargaroc who wears a hard steel mask which can be destroyed using the Skull Hammer. While he is wearing the mask his eyes are shown yellow; however, while fighting him without the mask they are shown as being red, possibly because the monster's mask has protective lenses over the eyes. He serves Ganondorf in the Forsaken Fortress.
