Not sure she and the Authority will be villains in the usual sense, rather a team of heroes with an outlook opposed to Superman's. The Authority has a take no prisoners proactive approach. I wonder if the Authority/Wildstorm Superman analog, Apollo, will be on the team?Zero knowledge of character or actress, so I guess I have no strong opinion on this? Other than the fact she's being described as a "villain" (and evidently also part of the Authority, another property about which I have no knowledge, other than that Gunn has a movie in the works), so at least not another C-list DC superhero taking up screentime.
