Hayden Panettiere, Voice of Kingdom Hearts’ Kairi, Dies at 36

The Kingdom Hearts community is mourning Hayden Panettiere, whose performances helped define several roles across the franchise’s early and modern eras. The actress, also known for Heroes, Nashville, and Scream, died unexpectedly at 36, with news of her passing emerging on August 16.

A Major Loss for the Kingdom Hearts Community

Panettiere’s connection to Kingdom Hearts extended beyond a single appearance. She voiced Kairi in the original Kingdom Hearts, Kingdom Hearts 2, and Kingdom Hearts Birth by Sleep. She later played Xion in Kingdom Hearts 3D: Dream Drop Distance, giving her a presence across multiple chapters and perspectives within the series.

Kairi is one of the franchise’s central characters, making Panettiere’s work especially recognizable to longtime players. Although the role represented only part of her career, it became one of her most enduring contributions to video games. She also voiced Samantha Giddings in the original Until Dawn and returned to the character in a post-credits scene for the game’s 2024 remake.

Death Confirmed as Career Spanned Film, Television, and Games

ABC News reported that a representative for Panettiere confirmed her death. No additional details about the circumstances had been released at the time of publication. She is survived by her daughter, Kaya.

Panettiere began appearing in commercials at 11 months old and took her first major television role as Sarah Roberts on One Life to Live. Her breakthrough came in 2006, when she played Claire Bennet on Heroes. Her film work included Remember the Titans, Ice Princess, and A Bug’s Life, in which she voiced Princess Dot. That performance also led to a Grammy nomination for the associated read-along album.

She later played Kirby Reed in Scream 4, returning for Scream in 2022 and Scream 6. Her final film role was reportedly Sarah Pangborn in the psychological thriller Sleepwalker, released in 2026, where she also served as executive producer.

Panettiere’s Legacy Beyond Acting

In addition to acting, Panettiere worked as a singer and model and used her public profile to support environmental causes. She was particularly involved in efforts to protect dolphins and whales from hunters, and later advocated for people experiencing domestic abuse.

She published her memoir, This Is Me: A Reckoning, in May 2026. Her death also follows the loss of her younger brother, actor Jansen Panettiere, who died in 2023 at age 28 from complications connected to an enlarged heart.

No further information about memorial plans or future releases connected to Panettiere had been announced. For players, however, her performances remain preserved in the Kingdom Hearts and Until Dawn games that introduced her work to gaming audiences.

Expert View

Panettiere’s passing highlights how much recognizable screen talent has contributed to game characters without being identified primarily as game performers. For Kingdom Hearts fans, her work is tied to Kairi’s identity across several foundational releases, while her Until Dawn role demonstrates a broader connection to narrative-driven games. The immediate impact is likely to be felt most strongly by communities revisiting those performances and remembering the actors who helped make story-focused games culturally distinctive.
