Nikki Wood, played by April Weeden-Washington and K. D. Aubert, is a character in the television series Buffy the Vampire Slayer.
Nikki Wood is a Slayer who was active in New York City in the 1970s. Her first appearance is in the Season Five episode "Fool for Love". In that episode, Spike tells Buffy Summers the story of how he killed Nikki, with flashbacks revealing that he snapped her neck following a battle on a subway train in 1977 and took her leather duster as a trophy, which he continued to wear until it was destroyed in a bomb blast in early 2004. Nikki reappears in the Season Seven episode "First Date", in which it is revealed that she had a son called Robin, now an ally of Buffy. The First Evil presents itself to Robin in the form of his mother, and informs him that Spike was the one responsible for killing Nikki. Nikki features in flashbacks in the episode "Lies My Parents Told Me", in which Robin tries and fails to take revenge on Spike.
Nikki appears in the story "Nikki Goes Down!" of the comic book miniseries Tales of the Slayers. In it, her boyfriend Li, a member of the NYPD, is killed during a battle with an oversized bat. She also appears in the prose short story "It's All About the Mission" of the novel Tales of the Slayer Vol. IV, in which her Watcher Bernard Crowley tries to avoid the Cruciamentum (a dangerous Watchers Council tradition in which a Slayer is stripped of her powers and tested) due to Nikki's pregnancy with Robin. Nikki features most heavily in her own novel Blackout, which tells the story leading up to her death as she battles Spike. The novel also reveals how she was called, and that she had rivalries with vampires Darla and Dracula. Nikki makes small cameos in the novel Queen of the Slayers, and the comics "Auld Lang Syne" and "The Chain".
