In the New 52 era of the “Supergirl” comic book, Reign was known as a Worldkiller, a being created by a group of rogue Kryptonian scientists. Reign and her fellow Worldkillers became enemies of Supergirl when they attempted to conquer Earth. Reign first appeared in Supergirl #5 (2012).
DCComics.com reports that, “Supergirl‘s producers promise that their take on Reign will be part of an exciting interpretation of the Worldkiller storyline, and Annable is the perfect actress for the role.”
According to Executive Producer Andrew Kreisberg, “Greg and I have wanted to work with Odette for years. We are beyond excited to have her join our cast in the scary, powerful and heartbreaking role of Reign.”
Unlike previous villains, Reign’s tie to Kryptonian history should present an interesting moral dilemma for Kara to work through: Her people are responsible for their creation. It lends itself to both an exciting and thought-provoking third season.
