Hydro-Man

Hydro-Man (first appearance 1981) is rarely mentioned in general and has certainly never been considered for a live action movie role – and that’s a real shame, because not only is he quite formidable (how could Spider-Man possibly hurt someone composed entirely of water?) he could also look pretty stunning using modern CGI (if you’ve ever been on The Amazing Adventures of Spider-Man ride at Universal Orlando’s Islands of Adventure, you get the idea!).

The classic version of the character is Morris Bench. Bench was a crewman on the cargo ship the U.S.S. Bulldog who was inadvertently knocked into the ocean by Spider-Man (after the hero had fought Namor) while a powerful experimental generator was being tested in the ocean.

As a result of his exposure to both the radiation generated by the machine and a particular deep sea bacteria, he gained the ability to become living water and can manipulate his liquid body however he pleases – he also bore a grudge against Spider-Man.

In a movie, he’d be somewhat similar in nature and threat-level to Sandman in Spider-Man 3, but aesthetically even more impressive. He’d be awesome to see.
