As Mother Superior she possessed great mental abilities, flight, intangibility, teleportation, force fields and an ability to alter her shape at will. When she was captured by S.H.I.E.L.D. they reversed the process returning her to an age in her late teens.

The daughter of the Red Skull and an unnamed washwoman from Exile Island, Sinthia Schmidt was deemed an unworthy heir by her father because of her gender. Spared death by drowning in the ocean, the girl was tutored by one of the Skull's disciples Susan Scarbo - later to be known as Mother Night.

Raised in Skullhouse, her father indoctrinated her in his racist philosophies and the young Schmidt proved to be a vicious protégé. As a teen she was dubbed Sin and given command of other young racist disciples in a group called the Sisters of Sin. Before his first death, of old age, the Skull had his daughter artificially matured to womanhood and engineered to have great mental powers - bestowing upon her the rank of Mother Superior.

In a battle with Captain America, Schmidt was horribly disfigured leaving her with the visage like that of her father, the Red Skull.
