Detailed Information of Superhero
Agatha Harkness (Heroes Reborn) (Earth-616)
Among the recreations on Counter-Earth was one based on Agatha Harkness, Franklin's former nanny. Although this pocket universe was instantly created, its inhabitants were given memories that "pre-dated" the creation of this reality. Agatha Harkness was a witch who resided in the city of New Salem, and the Scarlet Witch was her student. The Scarlet Witch was contacted through Agatha by SHIELD to join their newly formed super-hero team the Avengers. Agatha traveled with Wanda to Avengers Island and later returned to New Salem shortly there after.

When Loki betrayed his followers in order to absorb the power of the Avengers gamma core to empower himself, Agatha revealed that the Scarlet Witch's body was possessed by a the traitorous Avenger Hellcat. This revelation led to Hellcat's destruction and Scarlet Witch being freed from Loki's control. The Enchantress, betrayed by Loki, used her magic to transform Agatha back to her human form. She then joined Enchantress and the Scarlet Witch in pooling their magical powers to empower this earth's Thor, transforming him into a giant facsimile of Odin to battle Loki. Ultimately the heroes defeated Loki but at the cost of Thor's life. Agatha's fate following the defeat of Loki remains unrevealed.
