In Walking Bombs, the third chapter of the Flash Gordon series, Emperor Ming mistakenly celebrates Flash’s destruction, only to learn that Flash has survived and succeeded in securing the antidote for the Purple Death. Enraged, Ming orders his henchman Torch to deploy a squad of "Annihilations"—mechanical robots equipped with explosives and controlled remotely from Torch’s rocket ship. As Flash and his team traverse the icy wilderness of Frigia, they are ambushed by these deadly "walking bombs." In a desperate struggle, Flash finds himself grappling with one of the Annihilations just as it is set to explode. With Earth’s fate hanging in the balance, can Flash survive the attack and deliver the antidote in time?
