A couple of days ago saw new details revealed about Sigourney Weaver's villain role in Defenders in that she is playing a character named Alexandra.

Now we know it's clear Sigourney Weaver is playing an original character.

EW.com's online publication of the article states Alexandra in Defenders "has no code name and no comic-book history," but if that wasn't clear enough, the printed version also states: "Her evildoing Alexandra, whom Ramirez describes as an 'utter badass,' is not based on a comic-book character."

Showrunner Marco Ramirez also adds: “Sigourney is the kind of person you can buy as the smartest person in the room, who you can also buy as a person holding a flamethrower. Her character is a very powerful force in New York City. She’s everything Sigourney is: sophisticated, intellectual, dangerous." He pauses. "I’m sorry. I can only say a bunch of adjectives right now.”

So for fans hoping that Sigourney Weaver is playing Mephisto or Satana Hellstrom, it now seems unlikely, but that actually may mean there are plans for those two characters in the MCU.

Defenders will premiere on Netflix in 2017 with eight episodes with Marco Ramirez serving as showrunner.

Synopsis:

“Marvel’s The Defenders” follows Daredevil, Jessica Jones, Luke Cage and Iron Fist. A quartet of singular heroes with one common goal - to save New York City. This is the story of four solitary figures, burdened with their own personal challenges, who realize they just might be stronger when teamed together.
