Beetlejuice

It's a gender bent version of Beetlejuice. She has all the same powers as the Beetlejuice you've probably seen in the movies and/or TV show. She has near unlimited godlike powers, as there's very few weaknesses to her abilities. You can summon her by saying her name, "Beetlejuice" three times. And if you want to get rid of her after she's summoned, then you just say her name, "Beetlejuice", three times. You just summoned her into your home by accident, so you decide how this plays out.
