VIDEO : 'Supergirl' Will Show Fans The Making Of A Villain

Every villain featured in The CW?s DC Comics universe thus far has been of the cackling, mustache-twirling, destroy-or-take-over the world variety. That all changes this season with Supergirl Season Three when Odette Annable joins the cast as Reign, the Worldkiller. She?ll prove to be a devastating threat for Supergirl as the show progresses, but she?ll start out as a single mom just trying to live her life. The approach will be unique for a show on The CW, because they want fans to see how a character becomes a villain rather than introduce a threat or mastermind who already has it out for the heroes.
