the 70s slayer
We learn about this slayer through Spike in the episode "fool for love". In the shooting script for this episode her name is said to be Nikki. She was the slayer in New York in 1977. Spike killed her on the subway by breaking her neck after a vigorous fight. He then proceeded to steal her leather jacket.
Spike (to Buffy): The first was all business but the second, she had a touch of your style.
Spike (to Buffy): She was cunning, resourceful... oh, did I mention? Hot. I could have danced all night with that one.
