Nicholas Brendon, who played Xander Harris on “Buffy the Vampire Slayer” and Kevin Lynch on “Criminal Minds,” died in his sleep Friday, according to a statement from his family. He was 54.
The statement from his family read, “We are heartbroken to share the passing of our brother and son, Nicholas Brendon. He passed in his sleep of natural causes. Most people know Nicky for his work as an actor and for the characters he brought to life over the years. In recent years Nicky has found his passion in painting and art. Nicky loved to share his enthusiastic talent with his family, friends and fans. He was passionate, sensitive, and endlessly driven to create. Those who truly knew him understood that his art was one of the purest reflections of who he was. While it’s no secret that Nicholas had struggles in the past, he was on medications and treatment to manage his diagnosis and he was optimistic about the future at the time of his passing. Our family asks for privacy during this time as we grieve his loss and celebrate the life of a man who lived with intensity, imagination, and heart. Thank you to everyone who has shown love and support.”

As Xander, one of Buffy’s (Sarah Michelle Gellar) best friends, and a stalwart member of her Scooby Gang, Brendon won the heart of the show’s fans, with his loyalty and sarcastic quips, all as they fought the forces of darkness through their young adulthood. With his star on the rise during “Buffy,” Brendon appeared in movies like “Demon Island,” “Unholy,” and an adaptation of Charles Busch’s “Psycho Beach Party” with co-stars Amy Adams and Lauren Ambrose.
After “Buffy” ended in 2003, though, Brendon suffered publicly from addiction issues and mental illness, announcing at a 2004 fan convention that he was entering rehab for alcoholism.
Despite deepening personal issues, he appeared on 21 episodes of “Criminal Minds” as the former hacker Kevin Lynch. He was arrested numerous times, beginning in 2010. He was then arrested twice within two months in February and March of 2015, after which he went he went on the Dr. Phil show — but walked off. Later that year, he was arrested again, in Saratoga Springs, N.Y., for strangling his girlfriend. He was charged with felony third-degree robbery, criminal mischief and obstruction of breathing, and, when he pleaded guilty, agreed to enter rehabilitation again. The arrests continued for years: In 2017 — again, for assaulting a different girlfriend — and 2021 (on a prescription fraud charge), which was a violation of his probation.
Brendon was an occasional user of social media, and would give semi-regular updates on Facebook and Instagram about his life and health, as well as posting some of his paintings. In 2023, he posted on Instagram that he’d had two spinal surgeries and a heart attack in 2022, and wrote that “dealing with health insurance and pre-approvals feels nearly as emotionally exhausting and painful as dealing with my actual injuries.” In the post, he was soliciting funds from fans, writing “even though money can’t buy happiness, it can buy food and paint as well as pay for doctor appointments!”
On March 14, Hulu passed on a revival of “Buffy the Vampire Slayer” that the streamer had in the works — it would have starred Gellar returning to the role of Buffy. Had it moved forward, the show’s previous stars likely would have made appearances, but because of Brendon’s multiple arrests, he wasn’t thought to be one of them. In a Facebook livestream after Hulu passed on the project, Brendon lashed out at Gellar, saying she’d betrayed him by doing a sequel series without him
Born in Los Angeles as an identical twin with his brother Kelly Donovan, he started acting to help overcome his stutter. He was married and divorced twice.
