The internet has been trying to guess which famous Marvel baddie would be played by Alien's Sigourney Weaver since it was announced that she'd signed on for the show. Well, we now have answers... sort of. EW has revealed her character's name, but it's not a recognizable name in the Marvel rogue's gallery. Weaver is playing a character called Alexandra. And that's apparently not the secret first name of a more well-known villain—according to EW, she has "no code name and no comic-book history." The man helming the show, Marco Ramirez, gave us a bit of a peek inside Sigourney's character.
"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.”
That sounds like the most creative non-answer ever to me, but if you want more Defenders, you can check out EW's gallery here.
