Not only do they survive nearly every comic book battle to return to fight another day, they also allegedly invented the world's first sex doll. Borghild, of course, was not intended to replace the true woman who would bear the offspring of the master race, but rather to maintain hygiene in the trenches and prevent the Nazi soldiers from carousing with foreign wenches.

International Hygiene Exhibition? Damn, they sure knew how to have fun in the 30s.

Thanks to Fleshbot for bringing this matter to my attention.
