Alexander Lavelle Harris is a fictional character created for the action-horror/fantasy television series Buffy the Vampire Slayer (1997–2003). He was developed by Joss Whedon and portrayed throughout the television series by Nicholas Brendon and in two episodes by his twin brother, Kelly Donovan. He was conceived as an everyman and a male character for series heroine Buffy Summers (Sarah Michelle Gellar) to interact with, and to provide comic relief in the series. Xander is one of several friends of Buffy who assist her in saving the world against numerous supernatural events that plague Sunnydale, California, a town built over a doorway to hell.
Xander is based in part on Whedon himself, particularly in his high school years; as such, he is often the most geeky as well as witty and verbose of Buffy's characters. The character's overriding arc through the series has been his struggle towards maturity and earning the respect of others. In the canonical comic book continuation of the series, Buffy the Vampire Slayer Season Eight (2007–2011), Xander comes to achieve these goals in becoming the tactical leader of a global army of Vampire Slayers alongside Buffy.
Academic attention to the character has frequently come in the form of gender studies or with a focus on social class, reflecting Xander's working class home life and his fears of inadequacy. However, Xander's unique position as both outside and within the main group enhances his insight into the other characters, especially as the series continues; in Season Eight, he is Buffy's unofficial "Watcher", who watches over her and has a clear perspective. Critics have noted that although Xander frequently exhibits a struggle of masculinity, his storylines often focus on his romantic conquests. Following his unreciprocated love for Buffy, these include the tumultuous relationship with rich girl Cordelia Chase (Charisma Carpenter), brief fling with his best friend Willow (Alyson Hannigan) and his long-term relationship with ex-demon Anya (Emma Caulfield). In Season Eight, the character's older-brother relationship with Buffy's little sister Dawn (Michelle Trachtenberg) also develops along romantic lines, too late for Buffy to realize her compatibility with Xander.
The character of Xander Harris also appears in numerous items in the series Expanded Universe, such as comic books, tie-in novels and video games.
