Publication history

Agatha Harkness first appears in Fantastic Four #94 and was created by Stan Lee and Jack Kirby. Fictional character biography

1970s
Agatha Harkness was introduced as the governess of Franklin Richards. She easily fended off the Frightful Four when they came to abduct Richards, and admitted to the Fantastic Four that she is a witch. She then aided the Fantastic Four in battle against Annihilus. Through the actions of her son Nicholas Scratch, she was revealed as a member of the previously unknown New Salem, Colorado, a colony of witches of whom she had been the leader. Scratch had taken control of the town and persuaded its inhabitants that Agatha betrayed the community's secrets by working for the Fantastic Four. She was abducted and taken back to the community with Franklin to stand trial. The Fantastic Four followed and came into conflict with Salem's Seven, Agatha's grandchildren fathered by Scratch. The Fantastic Four defeated them and freed Agatha. In the process, Scratch's evil was revealed to the community of New Salem and he was banished to another dimension. Agatha became the magical tutor for the Scarlet Witch in the use of witchcraft. Scratch and Salem's Seven returned, and Agatha foiled their attempt to conquer the world. 1980s
Eventually, Salem's Seven took over the New Salem community again. They captured Agatha and killed her by burning her at the stake, though Agatha soon made her presence known to Wanda in what appeared to be a post-death astral form. In an ensuing battle between the Scarlet Witch and Salem's Seven, the entire community's energies were drawn into Vertigo of the Seven, who lost control of them. Wanda managed to capture some of the energy and funnel it away, but the entire town was destroyed. Following hints from Agatha's astral form, Wanda channeled the remaining energy to become pregnant with twin children of Vision, her android husband. Later, Agatha resurfaced, again alive and well, when Wanda's infant children began exhibiting odd behavior (disappearing for brief periods of time) and Wanda became unstable after her husband's dismantling; Agatha provided no explanation for her return. After Mephisto claimed that Scarlet Witch's children were actually fragments of his own soul and reabsorbs them, Agatha briefly mind-wiped Wanda's memory of her children in an attempt to help her deal with the trauma. Agatha later restored those memories soon after when Wanda became a pawn in a complex plot by Immortus. Agatha aided the Avengers in their battle against Immortus. 2000s

"Avengers Disassembled"

Wanda, again having no memory of her children, angrily confronted Agatha about their existence. Nick Fury of S.H.I.E.L.D. found what appeared to be Agatha's corpse in her home and concluded that Agatha had been dead for a long time. Some time later, a partially amnesiac Wanda tells Clint Barton she is under the care of her "Aunt Agatha" in a small apartment. However, this version of Wanda was later revealed to be a Doombot that replaced the real Wanda at some point. Ghost life
Agatha has since made her presence known in the New Multiverse as a ghost. She appears to Wanda and confirms her death at the hands of her protégé. She also concurrently serves as the omniscient narrator of Vision's ongoing solo title, having induced precognitive visions through an arcane ritual involving the murder of Ebony at some undetermined point before her death. Agatha fights alongside Wanda and the spirit of her biological mother Natalya Maximoff against a physical manifestation of Chaos which is attempting to destroy witchcraft. The two spirits channel their magic through Wanda and, after Quicksilver is summoned, they manage to defeat the being once and for all although this has gravely wounded Order, the Goddess of Witchcraft. Natalya sacrifices herself to restore Order and, in doing so, also returns Agatha to life. Despite noting that her and Wanda's paths are intertwined, Agatha chooses to have some time to herself to enjoy being alive again. 2020s

The Daughters of Liberty
Agatha Harkness later appears as a member of the Daughters of Liberty where she taught magic to its members. At the time when Captain America figured out that Dryad is a revived Peggy Carter, Agatha teleported herself to inform him that the threats that the Daughters of Liberty have been facing are connected with Aleksander Lukin's sister Alexa. Agatha later briefed the Daughters of Liberty's latest recruit Shuri about the situation involving Selene having Sharon Carter's soul. She then proceeded to transport herself, Sharon's Iron Patriot appearance, and Shuri to where Selene is located. Midnight Suns
During the battle with Corina (now calling herself Korrosion), a gigantic explosion of energy was unleashed due to the Black Mirror's destruction and neither Korrosion or Agatha Harkness were anywhere to be found. But, it turns out that the explosion have sent them back to their homeworlds where they belong. With her youth restored, Agatha had been gone into hiding ever since. Restoring the Darkhold
After taking out Necrodamus before he could launch an attack on Scarlet Witch, Agatha goes to meet her at her new Emporium witchcraft shop. The two exchange some small talk before Agatha brings up the topic of Chthon (which was sealed inside her soul) and the Darkhold (which Wanda had absorbed). Scarlet Witch thinks she's strong enough to take on this burden, while Agatha believes otherwise as she has become aware of several threats looming in the shadows looking to take advantage of Wanda. The two then have an interesting witch-fight that ends with Agatha conceding defeat. However, part of Agatha Harkness' fight against the Scarlet Witch was secretly about gaining access to the Darkhold trapped in Wanda Maximoff's soul. While Scarlet Witch is busy fending off attacks, Agatha slithered her way inside and ripped out Chthon's heart. Powers and abilities
Agatha Harkness has a gifted intellect and extensive knowledge of arcane lore. She can manipulate magical forces for numerous effects, such as psychokinesis, levitation, and the tapping of extra-dimensional energy by invoking beings or objects existing in vast dimensions tangential to Earth through spell recitations. Her ability to perform strenuous physical tasks had been reduced via advanced age. Before Agatha went into hiding, she is somehow de-aged back to the prime of her life. Ebony
Agatha's pet black cat possesses the capability to transform into a large ferocious wildcat with mystical senses. At one point, she was sacrificed so her owner could gain precognitive powers. However, Ebony is later resurrected through unknown methods. Reception

Television
 Agatha Harkness appears in The Avengers: United They Stand episode "The Sorceress' Apprentice", voiced by Elizabeth Shepherd. Agatha Harkness appeared in X-Men: Evolution, voiced by Pauline Newstone. Mystique recruited her to train Scarlet Witch before Harkness later aids the X-Men in saving Mystique. Agatha Harkness appears in the Marvel Cinematic Universe (MCU) miniseries WandaVision, portrayed by Kathryn Hahn. This version has a pet rabbit named Señor Scratchy instead of a cat. In 1693, she massacred her coven and her mother Evanora (portrayed by Kate Forbes) after being condemned to burn at the stake for practicing forbidden dark magic. In the present day, she senses Wanda Maximoff creating the fictional sitcom WandaVision within the town of Westview, New Jersey, and arrives to investigate. Unlike the locals, Harkness does not fall under the control of Wanda's powers. For most of the series, she poses as Wanda's nosy neighbor Agnes and manipulates the "show" in various ways, such as bringing in an imposter to impersonate Wanda's brother Pietro Maximoff to confuse her. Eventually, Harkness reveals her true identity to Wanda through the song "Agatha All Along" and discovers the source of the latter's powers, concluding that she possesses chaos magic and is the mythic figure known as the "Scarlet Witch". Harkness attempts to take Wanda's magic for herself, but the latter creates runes around Westview to negate her magic before trapping her mind within her Agnes identity. Hahn will reprise her role in an upcoming spinoff titled Agatha: Darkhold Diaries. Miscellaneous
