Dorado

Dorado is an anime-only character in the 1999 anime adaptation. He is a red-skinned bald man with various tribal-like tattoos on his body and is Killua's first opponent on the 200th floor. His weapon is a double-headed spear. At the beginning of the match, he gets the upper hand and is able to send killua flying with some powerful blows but Killua reverts to using his assassin techniques and knocks him out in one hit, breaking his spear in the process.
