Somewhat confusingly, Rex Rigid has two super-hero code names, which he apparently uses simultaneously. But Liquid Man (or sometimes "Liquid-Man") IS the same person as Mr. Waterballoon. Note that in panel 4 on page 4 of Megaton Man #1 (Nov. 1984), Megaton Man says: "Now what? I'm offbalance, careening headlong into Liquid-Man, alias Mister Waterballoon!"
