Joyce Summers
Joyce Summers is Buffy's cool, if not very oblivious, mother. She seems very okay with the idea of living on the mouth of hell and having a daughter who protects the world from its hellspawn. She tries not to interfere with her daughters slaying, but also tries to convince her to give it up, but seems to have some freakish pride of Buffy's abilities. Well, her daughter may not be on the honour role or a head cheerleader, but she sure can kick vampire ass! She is the head of an art gallery, and likes Nigerian masks that raise the dead, and sure can moisturise!
A lot of people have said how much they dislike her, but if your daughter came home every night covered in blood and has killed countless demons and even died once, well, we can't exactly hate her for having a Slayer for a daughter, can we (rhetorical question!)
