Annabelle is a sleek, athletic upper class british girl.  She's 17, stands 5 foor 6 with auburn hair and blue eyes.  Her choice of clothes is stylish and preppy.  Whether or not she has a nice smile, few people know since she's so serious all the time.

She was a Slayer in Training who is now the Chosen One. The only one.  With the Sunnydale villains reversal of Willow Rosenberg's Slayer spell, she is now the only known Slayer.
