Agatha Harkness in her youthful form. Often times the wielder of the darkhold and teacher/enemy/ally to Wanda Maximoff.
This version of her has very little to do with the mcu version of her, thus I did not use any of her outfits or designs. Also avoided using her original much much older form. May be some people's thing, but it ain't mine.
Streaked hair may help getting a more accurate hair style.
