Genius Society #83, Madam Herta, resides deep within the Clock Tower at the edge of the cosmos, pursuing the ultimate mysteries of the universe as a sorceress.

Thanks to de-aging technology, she maintains the youthful appearance of her prime. Disliking mundane affairs, she typically delegates such tasks to her puppets, that's why she can cook....

The Herta has the appearance of a young woman with fair skin and long, ash brown hair that frames her face. She has deep purple eyes and is noticeably taller and more mature looking than her puppet form.

She wears a black, white, and purple open-back, corset-style dress with detached sleeves that is accented with numerous white frills and keyhole embellishments. On her legs are a pair of translucent black tights with a black "hand" wrapped around her left thigh, as well as a pair of purple-soled black frilled boots, the right boot longer than the left. On her head she wears a large, wide brimmed black and purple hat decorated with large purple flowers, and in her hair she wears black and purple ribbons on either side of her face.

She also wears a black choker neckpiece with a white-frilled jabot, as well as a simple golden key necklace. She is often shown carrying a wand or key-shaped scepter, similar to that of a stereotypical witch.
