The Ubermadchen were Nazi femme fatales who appeared in an a Miss America special and Avengers 1959. I really enjoyed that miniseries and if you have a chance you should check it out.
This quartet of elite Einsantzgruppen (death squad) fled to Brazil after the war. There they were contacted and offered a pardon in order to work for ICON, a government organization using Operation Paperclip to recruit former Nazis operatives to fight communists. They came into conflict with Avengers, who defeated them. They were then interrogated and killed by one of the Avengers (Sabertooth).
