One of my favourite tropes is when the heroes and villains can actually be civil and chill around each other. We all heard that one, right? I mean, it's classic Doofenshmirtz/Perry the Platypus dynamics.
But consider, women helping women between a villainess and the heroine.
Villainess: I have come to VANQUISH you, Generic Heroine—! Wait a minute. Where are you?
Heroine: *is being bothered by a creep who won't take no for an answer*
Villainess, stepping between the two: You will leave this girl alone, OR FACE MY WRATH!!!!!
*The creep leaves*
Heroine: Phew! Thanks, Villainess. That guy just wouldn't leave me alone.
Villainess: Hey, no problem. Women helping women, am I right?
Heroine: Damn right. What are you doing here anyway?
Villainess: Oh, you know. Just trying to kill you.
Heroine: Oh, right. Hehe. Figures.
