Hydros is the elemental form of Iapetus and one of the five fictional Titans that Hades sets free in the film Hercules. He is slightly a hunchback, made entirely of ice and has blue eyes and a blue mouth. While being made of ice, he can freeze things by touching them with any part of his body. He can belch blizzards from his mouth.
His name could be refering to the greek word "υδρός" meaning "water".
