-Black Widow: Like Catwoman or Emma Frost, the Russian Natasha Romanov has known the two paths of the comic world: She left as a Russian spy trying to steal the secrets of Stark (Iron-Man), to later ally herself with The Avengers. She has broken the hearts of Hawkeye and Daredevil as well, and the recent portrayal of her at the hands of Scarlett Johansson, at least in me, has done the same. -Mystique -Harley Quinn
a few I can think of: Albedo (overlord) she can be considered a Villain no? xD dark samus (metroid) Evil version of Samus Aran. Boa Hancock (One Piece) a pirate can be considered a Villain? 18 (DBZ) at the start she is a villain :p. Widowmaker (Overwatch). 21 (DBS) the majin version Bowsette (mario) as long as she is not a gender bend and an alternate version :p. Silvanas Windrunner Ysera (warcraft) after her corruption. Monet (One Piece) she venom (marvel) Lady deadpool (marvel) Olga Discordia (Kuroinu) for the cultured bastard! Azula (Avatar) Artoria lancer alter (fate) Jeanne Alter (fate) dark Tyrande Whisperwind (warcraft) she gone full avenger and might fall in future expension so why no go with it in this Fanfic? xD Sith Ahsoka Tano (SW) from an alternate universe? dark Zelda (zelda) Kerrigan (starcraft) Don't hesitate to add some from alternate universe if there are women that can be interesting ^^.
