Fictional character biography
Seeking an heir, the Red Skull (Johann Shmidt) fathered a daughter by raping a washerwoman. After the woman died in childbirth, the Red Skull sought to kill his child in disgust over her being female but relented when one of his followers, Sarah Scarbo, asked to raise the infant on his behalf. The Red Skull agreed and left the girl, now named "Sinthea Shmidt", with Scarbo to be raised and indoctrinated with Red Skull's views as she grew up. The Red Skull later returned when Sinthea reached adolescence; through genetic manipulation, Sinthea was artificially aged into her early thirties, keeping her teenage mind while also gaining superhuman abilities.
As Mother Superior, she placed in command of a group called the Sisters of Sin, young orphan girls who were accelerated into adulthood and given psionic powers by the Red Skull after being indoctrinated by Sinthea. The Sisters of Sin would have many run-ins with Captain America (Steve Rogers) before Rodgers was able to reverse Red Skull's alterations, instantly reverting Sinthea and her followers into harmless children.
