#8 HYDRO MAN

Half man, half hydro, this is one of the best figures you can have in your Aquarium. In fact, I'm now wondering why he isn't listed higher in this list...

From wikipedia:
"Morris "Morrie" Bench gains his superpowers while as a crewman on the cargo ship the U.S.S. Bulldog, having been knocked overboard accidentally by Spider-Man (after the hero had finished a fight against Namor) while a powerful experimental generator is being tested in the ocean.

The combination of unknown radiation and his immersion in a deep ocean dwelling bacteria turns him into Hydro-Man. When he realized that he had become a man-of-water, he blamed Spider-Man for his disgrace and started to hunt him (through many showers, sewers and water valves), in order to get revenge on the hero, but was defeated in combat."
