Hydro-Man

Hydro-Man is a supervillain from Marvel comics and a recurring enemy of Spider-Man and the Fantastic Four.

Cargo ship crewman Morris Bench was accidentally knocked over by Spider-man during a battle with Namor, and was exposed to the combined force of an experimental underwater generator and strange volcanic gases, and it transformed his body into living water. Now as Hydro-man, Bench attacked Spider-man but was evaporated when Spider-man kicked him all over a hot roof top. Hydro-man has since battled Spidey several times.

At one point, Hydro-man battled rival criminal Sandman and they formed together into a huge mud monster. They were eventually dried out and separated, and while Sandman reformed, Hydro-man returned to a life of crime. He has joined such villain groups as the Frightful Four, the Masters of Evil, and the Sinister Twelve.

Powers and Abilities
Hydro-man has the ability to transform his body molecules into living water, and is thus virtually invulnerable to any physical attacks. He can harden his molecules into ice or form them into water vapor and can travel by blasting himself into the air.
