Agatha Harkness: Marvel witch, mentor and MCU scene-stealer

Agatha Harkness started as a low-key figure in Marvel comics and turned into one of the most talked-about characters on TV. You probably know her from WandaVision, where Kathryn Hahn turned a background witch into a character people quote and meme. If you want concise info — who she is, what she can do, and where to follow stories about her — this page collects the essentials and points you to reading, watching, and discussion.

Who is Agatha Harkness?

Agatha first appears in older Marvel comics as a witch with long ties to other heroes. She’s often shown as a mentor, teacher, or guardian who knows the darker side of magic. In the comics she has guided characters like the Scarlet Witch and even watched over young heroes. In WandaVision she was introduced under an alias, then revealed as a powerful and shrewd magic user who understands chaos magic better than most.

Her powers aren’t flashy like rocket blasts — they’re practical and clever. Think spells, wards, manipulation of mystical energy, and deep knowledge of occult lore. She can hide, probe memories, and bend spells in ways that change the rules around her. That combination of experience and sly personality makes her unpredictable: helpful one moment, dangerous the next.

Where to start: comics and shows

Want to read her in comics? Start with the classic appearances that tie her to big Marvel families and the Scarlet Witch. Those stories show why she’s trusted and feared. If you prefer TV, WandaVision on Disney+ is the key moment that pushed Agatha into the spotlight. After that show, Marvel announced further interest in her character, so keep an eye on streaming news for spin-offs or guest spots.
