Supergirl star Melissa Benoist will lend her voice to Freedom Fighters: The Ray, but she won't be playing Supergirl. When she shows up on the CW Seed animated series, she'll be Overgirl, the evil Earth-X version of Kara Zor-El.
“Melissa is so sweet, and so is her interpretation of Supergirl,” executive producer Marc Guggenheim told TV Insider. “It was fun to hear her voice records and see she’s capable of a darkness. I think she really enjoyed playing the bad guy for a bit!”
Overgirl appeared briefly in the Comic-Con International trailer for the series, which will take place partly in an alternate reality where the Nazis won World War II. However, since she didn't speak in this trailer, it wasn't clear if Benoist would play Supergirl's evil doppelganger. Per Guggenheim, that will definitely be the case when the series debuts this fall.
The Girl of Steel won't be the only cameo in Freedom Fighters: The Ray. Evil versions of The Flash and Green Arrow also popped up in the trailer, and other Arrowverse characters -- like The Flash's Cisco Ramon, Arrow's Mister Terrific and Vixen -- are slated to appear. The actors from the live-action TV series also reprised their roles in Vixen, the Arrowverse's other animated series.
According to the series description,
Raymond “Ray” Terrill was a reporter who discovered a group of government scientists working on a secret project to turn light into a weapon of mass destruction. But before he could report on his findings, the project head exposed Ray to a “genetic light bomb.” The bomb failed to kill him and instead gifted Ray with light-based powers. With these abilities, Ray realized he could go beyond reporting on injustice — he could take action to help stop it. Calling himself The Ray, he was recruited by Uncle Sam and the Freedom Fighters to fight violence and oppression wherever it exists.
Freedom Fighters: The Ray is based on writer Grant Morrison’s version of the character, who appeared in DC’s Multiversity event, rather than the iteration that first appeared in 1973’s Justice League of America #107.
Executive produced by Greg Berlanti and Marc Guggenheim, Freedom Fighters: The Ray will arrive on CW Seed in the Fall.
