Sin

While on his Isle of Exiles stronghold, the Red Skull chose a peasant washerwoman reminiscent of his mother to bear his heir. The woman died giving birth to a daughter. Furious, having wanted a son, the Skull spat in the dead woman's face, then took the newborn to throw her into the sea. Convinced by his underling Susan Scarbo to spare the child, the Skull ordered Scarbo to be her "night mother" and raise her in misery, anger and hate at Skull-House, an old Catholic monastery, only seeing her himself five minutes a week. The young Sinthia Shmidt was a brutal beast of a girl; Susan Scarbo's prize pupil. Learning he was dying and needing an instant heir, the Skull used his Deus Machina to artificially age Sinthia into adulthood, mentally indoctrinate her and empower her as Mother Superior. The Skull then aged and empowered four orphan girls as Sinthia's worshippers, the Sisters of Sin: Sisters Agony, Death, Dream and Pleasure. Taken in by Susan Scarbo (now Mother Night), the teenage Sisters became sadistic "counselors" in a youth camp designed to indoctrinate teen runaways into hate. Now calling herself Sin (with Death, Dream, Pain and Pleasure becoming Torso, Hoodwink, Slash and Raunch), Sinthia recruited "Roger Stevens," in reality Captain America transmuted into a teenager by the Eternal Sersi to better infiltrate the camp. Cap broke up the camp but the Sisters escaped, and Sinthia later became one of the reborn Skull's division chiefs. Abilities Being trained by her father, she is an expert hand to hand combatant and martial artist. She is also highly proficient in firearms and explosives. As the Red Skull's child, Sin also has a high level of intellect.

She currently works as a villain against heroes.
