CBS' 'Supergirl' Casting: Owain Yeoman Joins Melissa Benoist, Mehcad Brooks As Superman Baddie, Vartox! [WATCH]

CBS has announced the latest casting addition to their upcoming DC Comics TV show, Supergirl. Kara Danvers (Melissa Benoist) and Jimmy Olson Mehcad Brooks have their hands full when Superman villain, Vartox (Extant actor Owain Yeoman), shows up to cause trouble.

As we previously mentioned, the CBS superhero drama will follow the comic book adventures of Kara Zor-El (Benoist). In the mythology, Kara Zor-El escaped from the planet Krypton before its destruction years ago, but became lost in space. Crash-landing onto Earth, Kara tries to control her superpowers as she maintains her secret identity as Clark Kent's relative.

From what we mentioned before, Jimmy Olsen (Brooks) is a photographer at CatCo.,where Kara works. Jimmy has recently been living and working in National City, though the reason why is still a secret. What will be kept from the comics is Jimmy's romantic relationship with Supergirl. In the pilot, Jimmy and Supergirl end up working together to take down the Wonder Woman baddie, Lumberjack, who's under orders from the main big bad.

 Io9 first got the scoop by an unnamed source close to the production. Then Comic Book Resources got the confirmation from WBTV that The Mentalist actor will guest star in the show's pilot episode

In the official description, "Owain Yeoman plays longtime DC Comics villain Vartox, an alien convict, who has been hiding on Earth for the past twelve years. After Supergirl's emergence on Earth, Vartox seeks her out to ascertain her identity and do battle with her."

In the comics, Vartox set his sights on Power Girl after a "contraceptive bomb" on his home planet rendered all the women on his home planet, Valeron, sterile.
