Transformers is an iconic franchise that has stretched on for decades. Over time, the franchise has added new elements, new stories, and been rebooted numerous times. Each of these reboots comes with character changes to help audiences better connect with characters, such as the iconic leader of the Autobots, Optimus Prime. Optimus is portrayed as a heroic leader with a strong sense of justice. His primary transformation is a semi-truck, but this has been changed to different vehicles in other incarnations—such as a fire engine.

This list will focus on the best English voice actors who have portrayed Optimus Prime, as not everyone will have access to the vast catalog of multi-language dubs throughout the franchise’s extensive history. There have been a lot of voice actors who had great careers but did not capture the grandeur and iconic tone set by Peter Cullen — the original voice of Optimus Prime. However, these next actors all did justice to the role.

7 Alan Tudyk

Softer And More Conversational

• Most notable appearance: Transformers: EarthSpark
• Portrayed Optimus Prime: 2022–present

Alan Tudyk has a very iconic voice, one that has viewers saying “I know that voice” the moment they hear it. However, it is not very Optimus Prime-like. Despite this, he still manages to deliver a very great interpretation of the character.

His most notable voice work in the Transformers franchise is for the CG animated series Transformers: Earthspark. In this series, Optimus has a lot more diplomatic responsibilities and his personality is much warmer and more empathetic. This is where Tudyk really nails the role and is able to successfully bring this interpretation to life.

6 Chris Hemsworth

Orion Pax To Optimus Prime

• Most notable appearance: Transformers: One
• Portrayed Optimus Prime: 2024

Telling a story about Orion Pax is nothing new, as the character has been around since the first generation of the Transformers franchise. Chris Hemsworth has stated that he never tried to capture the distinctive qualities of Optimus Prime, but instead tried to create a new depiction of his precursor.

While he does not deliver the same grandiose that veteran Optimus Prime voice actors have been able to provide, Hemsworth’s portrayal fits perfectly with the Transformers: One movie’s Orion Pax interpretation. before eventually ascending to become the Optimus Prime we all know and adore.

5 Garry Chalk

The First Optimus Primal

• Most notable appearance: Transformers: Cybertron
• Portrayed Optimus Prime: 1999–2005

Garry Chalk has provided his voice to both Optimus Prime and his descendant, Optimus Primal. He first voiced Optimus Primal in 1996, but it would not be until 1999 that he would lend his voice to Optimus Prime in the form of a hologram.

His voice portrayal resembles that of a superhero, with plenty of bravado and gusto thrown into the voice. While this might not be what die-hard fans want for an Optimus Prime, it really does work to make for a memorable and engaging portrayal. It is both entertaining and enjoyable to watch any scene featuring the character. This is a voice that is ready for action.

4 David Kaye

Less Deep, More Balanced

• Most notable appearance: Transformers: Animated
• Portrayed Optimus Prime: 2007–2009

David Kaye’s portrayal does not feature any voice augmentation. A lot of incarnations use this to make the character of Optimus Prime sound more like a machine, but the characters of this series drop this trend to make the Transformers more relatable to the audience.

The Optimus Prime portrayal in Transformers: Animated is not yet representing the leader he is destined to be, as this Optimus is still growing into the role. He questions his actions, and this lets him evolve from someone who is more vulnerable to a much more confidently-spoken interpretation.

3 Jon Bailey

A Tribute To Peter Cullen

• Most notable appearance: Transformers: Combiner Wars
• Portrayed Optimus Prime: 2012–2022

Jon Bailey has voiced Optimus Prime in many different projects. His first portrayal was actually a joke for The High Fructose Adventures of Annoying Orange series, but he did such a great job that he would go on to voice the character in an animated series and multiple video games.

Jon would be the voice of Optimus in Transformers: Combiner Wars, where he draws a lot of inspiration from Peter Cullen’s version of the character—but Jon puts a lot more intensity into it. A similar intensity is used by actors trying to capture a Batman portrayal by focusing on a key element in how the character is known to behave.

2 Jake Tillman Foushee

A Dedicated Optimus Prime Voice

• Most notable appearance: Transformers: Cyberverse
• Portrayed Optimus Prime: 2014–2020

Jake Tillman Foushee has exclusively done voice work for the character of Optimus Prime as of 2020. This includes multiple animated series and video games. While Jon Bailey does an astonishing Optimus Prime voice, Fouchsee has been able to put more emotion into delivering his lines.

This allows the voice actor to help his character better express themselves through unexpected scenes and make them feel more real than simply reading lines from a script. Foushee may very well be the closest thing to a true successor of the original voice of Optimus Prime, and he’s earned the recognition of being the character’s modern interpretation.

1 Peter Cullen

The Definitive Optimus Prime

• Most notable appearance: The Transformers
• Portrayed Optimus Prime: 1984–2023

Peter Cullen is not only the original voice of Optimus Prime on both TV and in the feature film adaptations, but is still the best actor to take on the role. He blends the wisdom and authority of a leader, but he has also managed to capture every range of empathy and emotion needed to make Optimus feel believable and real.

It is very hard to pin down which is his most notable appearance, as he has provided his voice to the character more times than any other voice actor in every category—even including the times Optimus Prime has fallen in battle. He served as the voice for the original animated series, the live-action film franchise, numerous games, and even appearances in award shows and theme park rides. Hearing him as Optimus Prime just sounds and feels right.
