Amazon's adaptation of Garth Ennis and Darick Robertson’s The Boys has cast Karen Fukuhara as a series regular.

According to a report from Deadline, Fukuhara will play the character known only as Female, a mysterious assassin with superpowers and incredible fighting skills. When The Boys first come into contact with her, she doesn't speak and is feral, but learns what it means to be human over the course of the series.
