Willow Rosenberg is a fictional character created for the fantasy television series Buffy the Vampire Slayer (1997–2003). She was developed by Joss Whedon and portrayed throughout the TV series by Alyson Hannigan.
Willow plays an integral role within the inner circle of friends—called the Scooby Gang—who support Buffy Summers (Sarah Michelle Gellar), a teenager gifted with superhuman powers to defeat vampires, demons, and other evil in the fictional town of Sunnydale. The series begins as Buffy, Willow, and their friend Xander (Nicholas Brendon) are in 10th grade and Willow is a shy, nerdy girl with little confidence. She has inherent magical abilities and begins to study witchcraft; as the series progresses, Willow becomes more sure of herself and her magical powers become significant. Her dependence on magic becomes so consuming that it develops into a dark force that takes her on a redemptive journey in a major story arc when she becomes the sixth season's main villain, threatening to destroy the world in a fit of grief and rage.
The Buffy series became extremely popular and earned a devoted fanbase; Willow's intelligence, shy nature, and vulnerability often resounded strongly with viewers in early seasons. Of the core characters, Willow changes the most, becoming a complex portrayal of a woman whose powers force her to seek balance between what is best for the people she loves and what she is capable of doing. Her character stood out as a positive portrayal of a Jewish woman and at the height of her popularity, she fell in love with another woman, a witch named Tara Maclay (Amber Benson). They became one of the first lesbian couples on U.S. television and one of the most positive relationships of the series.
Despite not being a titular character, Willow Rosenberg holds the distinction of having the second largest number of appearances on episodes of Buffy and the spin-off series Angel. Alyson Hannigan appeared as Willow in all 144 episodes of Buffy, as well as guest appearances in three episodes of the spinoff Angel, for a total of 147 on-screen appearances over the course of both series. She is also featured in an animated series and video game, both of which use Hannigan's voice, and the comics Buffy the Vampire Slayer Season Eight (2007–2011), Buffy the Vampire Slayer Season Nine (2011-2013), Buffy the Vampire Slayer Season Ten (2014-2016), Buffy the Vampire Slayer Season Eleven (2016-2017) and Buffy the Vampire Slayer Season Twelve (2018) which use Hannigan's likeness and continues Willow's storyline following the television series.
