Atomic Robo disappeared two years ago when Tesladyne was invaded by Majestic 12 and transformed into ULTRA, a task force leveraging the U.S. surveillance and military industries against scientific pursuits deemed to be hazardous. Now, the few remaining Action Scientists finally have a plan to find Robo, but they've got to dive deep into ULTRA territory to do it! (And meanwhile, giant monsters from the sea might destroy all of civilization.)
