WBG+: WBG+ Presents: Hydroman

Created by Bill Everett, Hydroman first appeared in the premiere issue of Reg'lar Fellers Heroic Comics.

In 1940, a young chemical engineer named Harry Thurston accidentally created a compound that could convert human flesh into water, and he spilled some on his hand. He called out to his friend Bob Blake, who was then accidentally doused with a large amount of the substance and turned completely into "living water." Harry found an antidote and poured it into Bob. Restored to human form, Bob soon discovered that he could now transform any part of his body into water and control its form and movement. Deciding to put his new abilities to good use, Bob became a costumed crimefighter and called himself Hydroman.

Later, Hydroman gained a partner in the form of Jay Watson, a young employee of the Wizard Kid Radio Program. When exposed to sunlight, Jay could fly at the speed of light, leaving a rainbow-like trail in his wake which he could shape and control. In his costumed identity of "Rainbow Boy", Jay worked with Hydroman and also went on solo adventures.
