CBS has released a synopsis for "Supergirl's" April 11th episode, an installment titled "Myriad." The episode rundown reveals that former WWE Diva Eve Torres Gracie has been cast as Maxima and will appear in the episode along with returning villains Non (Chris Vance) and Indigo (Laura Vandervoort). The episode will feature Supergirl (Melissa Benoist) challenged by Non and Indigo's latest attack, which turns National City's population into their personal army.

While the synopsis doesn't tie Maxima to the villains' attack, it's worth pointing out that mind control and various psionic powers are among Maxima's powerset in the comics. Created by Roger Stern and George Perez, Maxima debuted in 1989's "Action Comics" #645. She is a member of the royal family of the planet Almerac and traveled to Earth on a quest to find a worthy suitor.

Torres Gracie previously had roles in "Scorpion King 4: Quest for Power" and the TV series "Matador." Her wrestling career began in 2007 when she won the WWE's Diva Search, and she currently serves as an ambassador for the WWE following her departure in late 2012. Maxima previously appeared on "Smallville," where she was played by Charlotte Sullivan.
