Agatha Harkness is an elderly witch from the town of New Salem. Unlike most of her family (Nicholas Scratch and the Salem's Seven), Agatha is a benevolent witch and was even the governess for the Fantastic Four's Franklin Richards. She was a mentor for the Scarlet Witch when Wanda undertook witchcraft to supplement her mutant hex abilities. Agatha even returned from a supposed death to aid Wanda during the abduction of her twin boys and her manipulation by Immortus. She remains a strong ally for the Scarlet Witch.
