Doctor Strangeglove And The Brain Children! Doctor William Magnus, and the Metal Men storm the office of General Henry Caspar, only to be turned away. Unbeknownst to them they are being observed on a remote monitor by Doctor Strangeglove and the Brain Children. Returning to their laboratory headquarters, Magnus and the Metal Men are met by Johanna Rome. Distraught, Rome has a terrible tale to tell. Once upon a time the United States Government bought an abandoned amusement park called "Happyland" and converted it into a Pediatric-Research Laboratory. Rome's pregnant sister volunteered to help with some experiments at the laboratory. The laboratory was run on nuclear power. Tragically, a problem with one of the reactors resulted in the laboratory's destruction and the death of Rome's sister. Due to the remote location of the laboratory the government, rather than decontaminate the property, merely sealed it within a large lead dome.
Chillingly, Rome has started receiving letters from her sister's unborn child. Rome, at first asked Caspar to look into the matter but has heard nothing from the General in two weeks. Magnus sends Gold, Mercury, Lead and Tin with Rome to investigate the Pediatric-Research Laboratory.
