From every corner, those who have followed Panettiere's work for the last few decades have highlighted her as a highly versatile talent with a career that touched movies, TV, video games, and more.Panettiere began her career in Hollywood at a young age, appearing in shows like Aliens in the Family, Unhappily Ever After, and One Life to Live before she was 10. Most, however, remember one of her biggest early roles as being the voice of a small ant named Dot in Pixar's A Bug's Life.While films like Remember the Titans, Dinosaur, Ice Princess, Bring It on: All or Nothing, and Tiger Cruise carried her time as a child star into the 2000s, video game fans have remembered her as the voice of Kairi in Kingdom Hearts 1 and 2. Fans and co-stars from Panettiere's early work – including Alyson Stoner, who took over as Kairi in Kingdom Hearts 3 – have shared fond memories online."From one Kairi to another… One sky, one destiny," Stoner said. "My deepest condolences to Hayden’s family, community, and the many lives Hayden reached. May you rest in freedom, Hayden. And sending love to my fellow KH community worldwide who have cherished Hayden’s work as Kairi through the decades."Putting together my absolute favorite scenes of Kairi played by Hayden Panettiere out of tribute.Once again Rest In Peace legend, and thank you for touching millions of KH fans’ hearts with your performance, from childhood to adulthood. 🤍🕊️ pic.twitter.com/8qMta2xH2p— Pauly🖤🏳️⚧️ (@PaulavenXIII) August 17, 2026 😢 What a sad end to such a beautiful Kingdom Hearts weekend.Actress Hayden Panettiere, the voice of Kairi, has passed away at age 36.

In 2011, she dipped her toes into the horror world as Kirby Reed in Scream 4. Nico Tortorella, who played Trevor Sheldon in the movie, offered his condolences with an Instagram Story."It's your birthday in a few days. The same day as my mom's. This one really hurts," Tortorella said. "I love you so much, sis. We grew up together in so many ways, fought like siblings, loved like siblings, and somewhere along the way, you just became family. I know you were in so much pain. I hope wherever you are now, you're surrounded by all the love and light you gave to so many of us. I miss you. I love you. Happy almost birthday, Hayd.""Rest in piece sweet Hayden," Scream co-star Melissa Barrera said in her own Story.Panettiere would reprise her role in the classic slasher franchise with Scream 6 in 2023. She was a horror icon in more ways than one, though, with another one of her most memorable gaming roles arriving in 2015's Until Dawn. She also appeared in its 2024 remake. Developer Supermassive Games was one of the many to take to social media to remember her as "one of horror gaming's most iconic final girls."We are deeply saddened to hear of the passing of Hayden Panettiere. Hayden brought Sam to life in Until Dawn, shaping her into one of horror gaming's most iconic final girls. Our thoughts are with her friends, family, and our community.
