Hydro-Man (Spider-Man The Animated Series)

Morris Bench once dated Mary Jane Watson, but she broke up with him after realizing she had made a big mistake. Soon after, Morrie was expelled from school and his parents enlisted him in the navy to keep him out of trouble. While in the special research unit, he was accidentally pulled overboard a ship while something was being lowered into the ocean. Exposed to something under the seabed, Bench's cellular structure was altered. After escaping from underwater, he was astonished to learn that he could convert his entire physical form into a watery liquid.
