Fluid Man

Fluid Man (real name Floyd Watterson and voiced by Paul Frees) could morph parts (or all) of his body into a liquid form, allowing him to, for example, sneak up on an enemy through a water faucet. He could also vaporize himself into a cloud or storm, but could be soaked up and trapped in a sponge (for example in “Televisitron“ and “Return of the Spinner”), or frozen solid in a block of ice (like in “Not So Nice Mr. Nice”). Fluid Man’s costume resembles a lime green wetsuit, complete with scuba mask and flippers. Fluey’s speaking style indicated that he was the beatnik of the group. His dark hair looks different in both his civilian and superhero clothes.

Backstory
Floyd Watterson was born into a long line of deep sea divers. When at the beach, a spill of toxic waste touched him. He was rushed to the hospital where he met Coil Man and Multi Man. They quickly became friends with each other.
