Pearl (Kelly Hu)
I will say that given some more time, Elijah might steal this spot, but as of now, it still belongs firmly with my beloved Pearl. I'm just grabbing what I said when I listed her among my favorite characters.

Ah, the magnificent HBIC that is Pearl. Oh, Kelly Hu, you are a goddess, simply put. And I refuse to accept that Pearl is gone. I just can. not. deal. Pearl was just transcendent. She was wise and beautiful, glowing and serene, and then she'd gouge your eyes or stab a wooden kitchen utensil into your stomach because you didn't follow the rules. See? The awesome. And even in her vampire state, she was so human in her love for a man centuries dead who betrayed her. Oh, Pearl. You deserved a better ending, damnit! I loved you so. WAH!
