The upcoming Disney+ series will go deeper into Percy Jackson’s fabled nemesis Medusa’s really dark story.

The snake-headed woman is one of the main character’s first major wins in Rick Riordan’s 2005 Percy Jackson and the Olympians trilogy.

However, Rebecca Riordan, the author’s wife and the TV series’ executive producer, revealed to Variety that Medusa will have a backstory this time.

She explained that “the only reason Medusa is not more fleshed out in the books was that it was Percy’s narrative and we don’t have her perspective,” because the books are written in first person.

“As a 12-year-old boy in 2005, I don’t think he had the bandwidth for deconstructing the patriarchy,” he said. “He was looking at it as, ‘This is a scary woman who’s trying to turn me into stone.’”

Rebecca revealed that Medusa’s story was “one of the first things” they explored in the writers’ room in order “to not have a patriarchal lens.”

Medusa is a woman who has sworn a vow of celibacy in order to express her love to Athena, the goddess of wisdom, in Greek mythology. Medusa eventually falls in love with the sea god Poseidon. However, the relationship becomes sexual one night, with the event taking place in Athena’s temple.

Medusa is then punished by Athena, who turns her into a gorgon who turns anyone who makes eye contact with her into stone. Percy Jackson, named after the Greek demigod Perseus, murders her and gives her head to Athena.

According to some accounts, Poseidon raped Medusa during their rendezvous at Athena’s temple.
