In 1938, Robo is asked by the U.S. Army to be their independent agent in arresting Baron Heinrich von Helsingard from his secret base in the Himalayas. Meanwhile, Helsingard himself has developed an otherworldly organ, a heart known as the Vril Organ, which bestows superhuman powers to the transplantee. This was Robo's first involvement with the military before World War II and the first glimpse of his interesting life.
