Hydroman: His Complete Stories from Heroic Comics (Superhero Comics, Golden Age, Pre-Code)

“This is the story of Harry Thurston's great discovery – HYDROMAN! Harry is a young chemist who devotes all his spare time to constructive invention, confining himself day and night to his laboratory.....

“ A huge container of remarkable solution was spilled, and splashed over Bob Blake, Harry's friend, causing him to disintegrate and became a pool of water on the laboratory floor! Promptly and antidote was concocted, and with the aid of this, Bob regained his natural form. He then discovered that he could control his change merely by power of thought – thus was created HYDROMAN!” (From the Publisher)
