Peter Cullen Dies at 85: Remembering The Iconic Voice Behind Optimus Prime

This is the fourth death I’ve had to write about in a week, and it’s making me so damn sad.

First Hayden Panettiere, then Dolly Parton, then Tim Curry, and now Peter Cullen. I hate writing these things. It’s hard to process how fragile life is, especially when so many talented and beloved people who have been part of our lives through movies, television, music, and pop culture are suddenly gone. It’s a lot to take in.

This one hits especially hard. Cullen, the legendary voice actor best known as Optimus Prime in Transformers, has died at the age of 85. His family confirmed his passing and shared the following statement with TMZ:

“Peter Cullen passed away peacefully, surrounded by his loving family – and held in the hearts of his many friends and countless fans worldwide. His family asks that you honor his remarkable legacy by serving your communities and leading others with compassion, integrity, and loyalty, and always remember ‘be strong enough to be gentle.’”

A cause of death hasn’t been revealed.

For generations of Transformers fans, Cullen wasn’t simply an actor playing Optimus Prime. He was Optimus Prime. That voice was commanding, warm, heroic, and instantly recognizable.

I grew up watching Transformers, and it was one of my favorite cartoons as a kid. Optimus Prime was a huge part of that. Cullen gave the character a presence that made him feel larger than the cartoon itself.

Optimus was the kind of hero you wanted to follow into battle, but Cullen also gave him a humanity and gentleness that made the character so special. That connection has stuck with me all these years.

Cullen first voiced Optimus Prime when the original Transformers animated series debuted in 1984. Other actors would eventually play the Autobot leader across different corners of the franchise, but for a massive number of fans, Cullen is the definitive voice.

When Michael Bay brought the Autobots and Decepticons to the big screen with Transformers in 2007, bringing Cullen back to voice Optimus was absolutely the right call. His voice immediately connected the new live-action version of the character to the Optimus so many of us had grown up with.

He continued voicing Prime throughout the live-action movie franchise, with his most recent performance coming in Paramount’s Transformers: Rise of the Beasts in 2023.

It’s difficult to imagine Optimus Prime without hearing Cullen’s voice in your head. His career, however, was much bigger than one Autobot.

More recently, Cullen joined Invincible as Thaedus, an important ally to Mark Grayson in the fight against the Viltrumite Empire. It was another great role for an actor whose voice could immediately give a character authority and weight.

Then there’s Eeyore. Cullen voiced the lovable, perpetually gloomy donkey across numerous Winnie the Pooh projects, which is pretty incredible when you think about the range involved. The same actor who gave us the powerful voice of Optimus Prime could turn around and completely disappear into Eeyore.

He also voiced Monterey Jack in Disney’s Chip ’n Dale: Rescue Rangers, another character that became a childhood favorite for a whole generation of animation fans, including myself.

Anime fans may have heard Cullen without even realizing just how much history was attached to the man speaking. He served as a narrator for Cartoon Network’s Toonami, helping introduce viewers to shows such as Dragon Ball Z, Outlaw Star, Rurouni Kenshin, and Tenchi Muyo, along with many other series that helped turn anime into appointment television for countless kids and teenagers.

The guy had one hell of a career as a voice actor. Cullen had one of those rare voices from our childhood that followed us into adulthood. I watched Optimus Prime as a kid, then years later got to hear Cullen return to the character on the big screen. There’s something awesome about that kind of longevity.

The guy was a legend, and he was so damn talented. Voice acting sometimes doesn’t receive the same attention as an on-camera performance, but Cullen demonstrated exactly how powerful it can be. He could create character, emotion, authority, humor, sadness, and warmth using nothing but his voice.

Optimus Prime will always be his defining role, and understandably so. Cullen spent more than four decades helping shape the character into one of pop culture’s great heroes.

His performance became inseparable from Optimus and helped establish what the character was supposed to represent: courage, compassion, loyalty, strength, and leadership.

Those qualities also make his family’s request to fans particularly fitting. Honor Peter Cullen by serving your community, treating people with compassion and integrity, and remembering to “be strong enough to be gentle.”

After a week filled with loss, I’m tired of writing goodbye articles. Each loss carries its own history and memories, but Cullen hits a very personal piece of my childhood. A lot of Transformers fans are going to feel the same way.

Peter Cullen gave Optimus Prime his voice, but more importantly, he gave him a soul. For more than 40 years, that performance inspired kids to believe that being strong didn’t mean giving up kindness or compassion.

That’s a pretty awesome legacy to leave behind.

Rest in peace, Peter Cullen.

Till all are one.
