Yzma in her transformed cat form from The Emperor's New Groove. Sometimes the whiskers are a bit funky and will generate more than 3 on either side of the character's face, but other than that it works great from my testing. The background trained in the image screencaps is also pretty strong, so lower down the weight if you can't get the desired background you're trying to make happen in your generations.
Positive Prompts: CatYzma, furry, feral, feline, female cat, grey body, grey fur, dark-purple eyes, pink nose, whiskers, fluffy tail
Extra: vial, holding vial, evil smile, shocked expression
Most of her scenes show her holding a vile, so if it pops up randomly and you don't want it, then just put "vial, holding vial, holding object" in the negative prompts and that should help.
