'B' is for Buffy in my Whedon-verse alphabet :D
Don't let the shiny satin floss fool you, it's not actually that messy :D
Buffy is the title character in Buffy: the Vampire Slayer. Here's a LINK for her. I'm not going to go in to her history and storyline as it is very detailed and complicated! In the show, Buffy is played by Sarah Michelle Gellar:
Buffy first appeared in a movie where the 'Shallow-Cheerleader-is-a-Vampire-Slayer' was done for laughs. Love the movie!!!
I love the show, too, but they are both entirely different in the atmosphere (and definitely the seriousness level).
The show is full of crosses, but I think the cross symbol was chosen for the project because Buffy usually wears a cross necklace (also given to her by Angel) in most of the episodes.
Buffy's a great character, though I will admit that I like her better in the earlier seasons before her story started getting really dark and convoluted. Also, if there was no Buffy there would be no Xander, no Drusilla, no Angel, no Giles.
And no Spike.
Spike is my favorite.
