In June 2017, Bliss was cast in her acting debut as Tuktirey or Tuk in
James Cameron's
Avatar sequels, beginning with
Avatar: The Way of Water in 2022; she was nine years old after filming completed and was thirteen when
The Way of Water premiered. Bliss related closely to Tuk as she is both biracial and the youngest of the family like her character. She also went to school onset due to the long hours required in filming. Since 2021, she has uploaded cover versions of songs and has sung some of her own. Her first studio album,
Confessions of a Preteen, was released on January 20, 2023. On November 15, 2022, Bliss was cast as Stella Zhau both in the
Nickelodeon live-action television series
The Really Loud House (2022–2024) and the
Nickelodeon live-action television film
A Really Haunted Loud House (2023). In October 2023, she was cast as Cat McCoy in
The Life of Chuck, which was directed by
Mike Flanagan and was based on the short story of the same name by
Stephen King. The film has its world premiere at the
2024 Toronto International Film Festival and was distributed by
Neon in North America in June 2025. Bliss returns as Tuk in
Avatar: Fire and Ash in December 2025, having already filmed the second and third films of the franchise simultaneously by James Cameron to avoid the young cast aging. She also filmed flashback scenes for the planned fourth film during this time, which would have a time jump and would explore Tuk at Bliss' current age; the film would push through depending on the box office performance of
Fire and Ash. On November 21, 2025, Bliss released a new single, "You Make Me Wanna Dance," with a music video released inspired by high school romance films. On January 6, 2026, she released another single, "Chemistry." ==Filmography==
