Who do you think has been the most badass, fearless, threatening and well written female villain in gaming?

Is there such a female character?

Or do you think there hasn't been a proper female villain in gaming yet?

Who is your favorite female villain in gaming and why?

The Boss from MGS3..even though..well you know.

I know what you mean. ;) And dammit, ain't that a great one you brought up? :D

And here I was thinking I couldn't remember any female villains in the games I have played. That's definitely a great pick!

Harley queen, not enough well writed female vilain.

There are some good female villains that tend to screw up the protagonists badly, like Nassandra in Dark Souls 2, Excella Gionne in Resident Evil 5 or Bloody Mary in The Wolf Among Us.

There aren't, however, many iconic female villains. I guess...Mary/Maria in Silent Hill 2 impacted everyone who played it? And it's not a villain per se. Someone already mentioned The Boss which is an awesome pick.

Final Fantasy 8's Ultimecia would be my choice.

GLaDOS from the portal series.

This. I would also add Glados from Portal.

I didn't particularly loved the game, but I'd be lying if I said Brooke Augustine didn't make me feel uneasy every time she had screen time.

Really hated her in a good way.

Also, seeing Faelco's avatar made me remember a villain from Danganronpa. I will not say anything more because spoiling that game is almost criminal, but if you have played it you most likely know who I'm talking about. That was a doozy of a villain and a total joy to see unveil. 

Villian from DanganRonpa is certainly a contender. The Boss from MGS3 is a excellent choice.

I also think of Selvaria (although, I don't consider her much of a villian) and Edea.
