Interestingly, on one occasion Ralph turned evil when the Gingold he had ingested had been corrupted with an infusion of the Flash's super-speed force. Gaining the ability to transform objects into rubbery substances, Dibny as the Molder fought his best friend until the Flash finally found a way to defeat him.
While Stretch didn't have a second alter ego, a red haired friend of his world's Flash named Blinky Boylan was able to grant himself temporary superhuman strength. However, a crook absconded with his alter ego of the Muscleman and battled Blinky, who with the help of Flash defeated the crook.
Ralph's own Molder costume was later adopted by the original Molder, a plastic creating villain who had previously battled Batman and Plastic Man, and reappeared as such during the Crisis on Infinite Earths during a Villain War.
