Agatha can be found at the Ancient Sanctum in Avengers Campus. Her location is part of the Treat Trail.

Her new costume includes a white collared shirt, a purple skirt, and a blue full-length coat.

The coat has purple detailing, like on the inside of the cuffs. Agatha wears her amulet around her neck and her hair down in long waves.

Agatha’s new costume is based on one shown in the trailer for “Agatha All Along,” as seen below, portrayed by Kathryn Hahn. The show will premiere on September 18, streaming exclusively on Disney+.

Hahn is joined by Patti LuPone as Lilia, Aubrey Plaza as Rio Vidal, Sasheer Zamata as Jennifer, Debra Jo Rupp as Sharon, and Ali Ahn as Alice. Joe Locke will play Billy Kaplan, who in the comics is known by the moniker “Wiccan,” and is the son of the Scarlet Witch. Billy (as Billy Maximoff) was played by Nolan Englund in “WandaVision.”
