PAST: Found out she was a Slayer, got thrown out of school after burning down the gym (which was full of vampires), parents got divorced & moved to Sunnydale.
WEIGHT - Always slim, but starts of curvy, ends up quite thin.
CLOTHING; Mini dresses, knee boots, blouses and sweaters, leather trousers, leather jackets (typically 90's wear)
POPULARITY: Was popular in old school but known as a bit of weirdo in new school (due to the weird things that happen around her thanks to Slayer duties)
FRIENDS: Willow - Best friend & very powerful witch, Xander - Best friend, Giles - Watcher & father figure
FAMILY: Joyce (Mother) - dies. Dawn (Sister) - mystical Key sent to Buffy in the shape of a sister to be protected (too confusing to write about). Hank (Dad) - Had an affair & rarely seems to call/see Buffy.
LOVE INTERESTS: Angel - vampire with a soul & first love. Have a tricky relationship & he eventually leaves as he feels he's doing her more harm than good. Riley - her 'Mr. normal' boyfriend. Long term but she doesn't love him. Spike - soulless vampire, loves Buffy & she uses him. Love hate relationship. Fight a lot, have sex for a while & she relies on him a lot. Tells him she loves him & he dies heroically.
DEATHS: Drowns & gets resuscitated by Xander. Jumps off a tower into some mystical thingy & gets brought back half a year or so later by a ritual performed by Willow, Xander & their partners at the time. They thought she may be in hell (due to the mystical thingy she jumped into), but she was in heaven, and struggles to deal with being alive after that - becomes quite destructive & depressing.
