Hydro-Man was a supervillain with the power to control and turn his body into water.
Morrie Bench used to date Mary Jane until they broke up. He then joined the United States Navy. Whilst in the service, a freak accident dragged him to the bottom of the ocean and his body was covered in a strange chemical. He could now turn into water and control any liquid as long as he was close to it. He then called himself Hydro-Man.
Hydro-Man then went back to trying to impress Mary Jane. He began a series of high end crimes to get treasure for her. He kidnapped her but she ran from him. Spider-Man intervened but he was able to evade the hero. Mary Jane led Hydro-Man to a rooftop on a hot day far from water. He tried to grab her but splashed across the roof. He began evaporating but was never seen again having apparently died in the process.
Hydro-Man can control water along with turning his body into water. He is able to control the water from any source such as pipes running through the city.
Morrie requires constant contact with water and a significant time away makes him weak. This can become even worse on hot days when the sun quickly evaporates water.
He is obsessive. He believes that he can have Mary Jane back even after she clearly states otherwise.
Hydro-Man was a replacement for Sandman on both series, who could not be used in the series due to a proposed film. Both characters have similar powers, with the other being made of sand. While Hydro-Man was a member of the Frightful Four, Sandman was one the original team.
Hydro-Man is one of the few characters believed to have actually died since he is never seen again after evaporating.
In terms of Fantastic Four and Spider-Man being in the same universe, it's unknown just whether the version on Fantastic Four is the original or clone. "And the Wind Cries Medusa" aired one week after "Hydro-Man", though this is not indicative of an exact timeline. Given the backstory of Wizard and Medusa, it is probable that Wizard similarly helped Morrie control his powers and when the team was defeated he went after Mary Jane since Warren needed to develop the clone.
