Agatha Harkness Halloween Costume
Agatha Harkness has predominantly appeared as Agnes, and with her quirky and humorous demeanor, she was given the primary comedic role in the sitcom reality. Throughout the series, she frequently interjects with jokes and witty comments for humorous effect. However, once revealed as the witch Agatha Harkness, her persona takes on a darker and more sinister quality. She regards Wanda Maximoff as unworthy of her magical abilities, feeling contempt for the fact that Wanda squanders her magic to maintain the false reality within the Hex.
Harkness further criticizes Maximoff's less-than-heroic actions, including her past affiliations with HYDRA and her confinement and torment of the citizens of Westview. Harkness aims to plant seeds of doubt in Maximoff's mind. Arrogantly, Harkness taunts Maximoff during their confrontation, convinced that she has the upper hand. Ironically, this proves to be her downfall, as she inadvertently gives Maximoff the inspiration to use her original protection spell against her.
