Villainess.

Such an obscure yet recently popularized term... A villainess is a character who has always been diametrically opposed to the heroine of a romance drama.

What makes a person a good villainess?

The fact that she's unabashedly beautiful and charismatic, yet also rotten inside?

The fact that she's incredibly loathsome, greedy, and selfish?

That she's reasonably strong enough to be a hurdle, yet ultimately powerless in the face of a determined heroine?

That despite all these character flaws, a Villainess's greatest virtue is unwilling to give up until the last of their breath, in pursuit of her personal desire?

If those are the hallmark of a successful Villainess. Then, I might be the wrong person to play that role.
