Circe Sionis (Earth-Prime)

"Sweet Circe Sionis. Poked the baby blues out of some corporate bigwig."

- Alice

Circe Sionis was the deceased daughter of Black Mask.

Imprisonment
In 2015, Circe Sionis was assaulted by Ezra Castellanos and gauged his eyes out with a spoon. She was then arrested by Crows Security and was sent to Arkham Asylum after the organization manipulated the evidence to show that she assaulted Castellanos instead.

In 2020, Sionis was trampled to death by inmates, including Alice, during the Arkham breakout caused by Batwoman.
