It had been a few years since Nuclear War III, peace had returned to the now sparsely populated Earth. The war mentality had many damaging psychological effects and the radiation often exposed people to strange physical effects. Xavier had been unsure of the new peace; he was still often ready for combat at a moment's notice. He had been transformed into a woman by the radiation. Doctors had suspected the effects were cosmetic only, but he still used protection before getting sexually involved. He was shocked to wake up after a one night stand the night before to find himself very pregnant. He could only guess the radiation had hastened the process. He'd probably give birth by nightfall. So much for doctors saying his feminine nature was "cosmetic" only, and so much for these methods of birth control that couldn't compete with the radiation!
