on social media that "he passed in his sleep of natural causes". His family added: "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.

 "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". Brendon played Xander Harris in Buffy the Vampire Slayer over seven seasons between 1997 and 2003 - best friend of the titular character played by Sarah Michelle Gellar. A planned reboot of Buffy was cancelled, Gellar announced to fans on Instagram  this month.

 Following news of her co-star's death, Gellar, quoting a famous monologue by his character in the series, wrote: "They'll never know how tough it is to be the one who isn't chosen. To live so near to the spotlight, and never step in it. But I know. I see more than anybody realizes, because nobody's watching me."

 "I saw you Nicky," she added. "I know you are at peace, in that big rocking chair in the sky". The Los Angeles-born actor received three Saturn nominations for his role in Buffy, two for best TV actor and one for best TV supporting actor. Brendon's twin brother Kelly Donovan Schultz also stood in as his brother's body double in two episodes of Buffy.

 He also starred alongside Alyson Hannigan, who shared a tribute in a post on Instagram. She wrote: "My Sweet Nicky, thank you for years of laughter, love and Dodgers. I will think of you every time I see a rocking chair. I love you. RIP". Following Buffy, Brendon appeared in various shows including Criminal Minds, Private Practice and Kitchen Confidential. His film credits also include Psycho Beach Party, Big Gay Love, and Redwood.

 Brendon was open about his health struggles, including a heart attack, and underwent two spinal surgeries for cauda equina syndrome, a rare condition that can affect movement as well as bladder and bowel function. The actor also lived with a stutter, later advocating the cause as a spokesperson for the Stuttering Foundation of America. The late actor had also opened up about his struggles with substance addiction, alcoholism and mental health issues.

 His family told the Hollywood Reporter: "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". (BBC)
