Peter Cullen, the Canadian voice actor best known as Transformers’ Optimus Prime, died on August 26, 2026, at the age of 85. Reports say he passed away at his Los Angeles home surrounded by family. For players and animation fans, his death marks the loss of a performer whose work connected classic television, major film franchises, and video games across six decades.
What changed for fans of Cullen’s work
Cullen’s career began with television announcing in 1967 and eventually included roles across cartoons, movies, commercials, trailers, and games. He became one of the defining voices of Optimus Prime, performing the character in Transformers cartoons, feature films, and a broad range of interactive projects.
His other widely recognized roles included Eeyore in Winnie the Pooh and Thaedus in Invincible. He also appeared in Knight Rider, the 1981 Spider-Man series, and the animated Dungeons & Dragons show. Cullen received an Emmy nomination in 2011 and earned an Emmys Lifetime Achievement Award in 2023.
Which games and characters are part of his legacy
Cullen was among the earliest actors to voice Mario, performing the character in Saturday Supercade during its 1983–1984 run. Although his video game credits were less extensive than his television and film work, his most important gaming role remained Optimus Prime.
He reprised that part in 12 Transformers games released between 2007 and 2016, with Transformers: Earth Wars among the later appearances listed in the source material. His final game role was also Optimus Prime, whose voice was used in Fortnite in 2023. Cullen additionally narrated Crystal Crisis in 2019 and voiced Eeyore in Disney Magical World 2 and Piglet’s Big Game.
One unreleased project provides a notable glimpse at what might have been. Cullen recorded work for Blizzard Entertainment’s Warcraft Adventures: Lord of the Clans in the 1990s, but the adventure game was canceled in 1998, leaving that performance officially unavailable.
What comes next for fans and the industry
Cullen’s existing performances will remain available across the games, series, and films that feature them, giving audiences a chance to revisit his work rather than wait for a new performance. His Optimus Prime appearances are especially spread across different Transformers releases, while his roles as Mario and Eeyore reflect the range of his career.
His passing also arrives during a difficult period for fans of established entertainment franchises. The source reports that actor Tim Curry died on August 25, one day before Cullen, while Kingdom Hearts Kairi actress Hayden Panettiere died earlier in August. These losses underscore how many familiar voices from games and related media have shaped audiences over several generations.

Expert View
Cullen’s importance to gaming comes less from the size of his gameography than from the strength and longevity of his signature roles. Optimus Prime gave multiple generations a consistent voice across animation and interactive media, while his Mario and Eeyore credits show how broadly his work reached. The most meaningful way to assess his legacy is therefore through continuity: Cullen helped make familiar characters feel recognizable whenever they returned.
