When Abigail was thirteen years old, in 1964, the Asgardian sorceress Enchantress stumbled upon her playing in a park in New York. Moved by Abigail's innocence and the inability to reminisce her own childhood due to the longetivity of her people, the Enchantress decided to approach her and offer her a gift: a box containing two enchanted cupcakes and a vial. The cupcakes could prevent her from aging, and the vial could undo their effect. Abigail ate one of the cupcakes immediately, and stopped aging. Abigail's parents initially didn't understand why she stopped growing up, and she always insisted to continue acting her physical age. They eventually came to terms with it and were glad they had a daughter that would never leave them, so they helped her keep her secret. Abigail kept the vial, and decided she was going to use it once her parents passed away. Abigail's eternal youth additionally allowed her to learn different skills like martial arts and several languages.
