Peter Cullen, the iconic voice actor best known for his role as Optimus Prime in the Transformers franchise, has died at 85. Cullen died Aug. 26, 2026 at his home in Los Angeles surrounded by family. No cause of death has been released but the death leaves millions of fans mourning the loss of a voice that was part of generations and had a profound influence on American animation and pop culture.
The Voice That Was Optimus Prime
Cullen’s first turn as Optimus Prime was in the original 1984 animated series, giving life to a character who was more than a leader, but a figure of calm authority and empathy. He was able to demonstrate strength and compassion and make Optimus relatable and resonate with fans of all ages . He continued to deliver his signature take on Optimus in many animated series, video games, and live-action movies, most recently in the 2023 film *Transformers: Rise of the Beasts* (Variety Australia). He knew how to be powerful without being cold and that made Optimus a true hero to many.
Eeyore: A Gift of Divergent Ability
He’s best known for the voice of Optimus Prime, but Cullen’s role as Eeyore from Winnie the Pooh showed a different side of his huge talent. He lent his incredible range to the voice of the adorable but sad donkey in The New Adventures of Winnie the Pooh and a number of Disney productions. The Guardian also notes the range of the performer, with the commanding Optimus compared with the mournful Eeyore. For a lot of these people, these two characters were fond memories, a representation of the beauty of childhood innocence and imagination.
A Career That Spans Generations
Cullen’s remarkable journey went far beyond his two most famous characters. He started his career in the late 1960s, working in television, film and video games to create an inspirational body of work. He also provided the voices of memorable characters including KARR in *Knight Rider*, the creature in the original *Predator* and the title character in the 1976 version of King Kong.
Personal Connection to Optimus Prime
Few know that Cullen drew inspiration for Optimus Prime from his own life, including his relationship with his brother, a U.S. Marine. Cullen wanted to develop a character who was strong, but also had a heart and was a leader. This deep connection to the character gave the character an emotional depth, and made Optimus Prime an enduring symbol of hope and kindness in the animation world .
A Legacy Reaching Out

Through his characters, he created strong bonds that have transcended generations. Cullen received a Lifetime Achievement Award at the 2023 Children’s & Family Emmy Awards for his work in voice acting and children’s entertainment .
