@EmmyEyyy : Agreed, though to me the most badass villainess I read is from a WN that to my knowledge isn't translated by anyone.
Where when the villainess was tied up inside a magic-sealing circle to slowly weaken her through starvation such that they can safely do a public execution without her turning the table.
Her brother (a capture target) dropped by and whispers into her ear how he'll become the country's savior through his scheme to use the chaos of the current events.
At which point she snaps around, and BITE HIS THROAT OFF (yes, he's dead for real)
