Generally depicted as a brave and noble leader, Optimus Prime is the supreme commander of the Autobots in their fight against the Decepticons.

In the Transformers mythology, Optimus Prime is a Cybertronian, a member of an extraterrestrial species of sentient self-configuring modular robotic lifeforms (e.g., cars and other objects), a blend of biological evolution and technological engineering.

Other actors include Garry Chalk, Neil Kaplan, David Kaye, Alan Tudyk and Chris Hemsworth.

In the Transformer's story, Optimus Prime, also known as Orion Pax, embodies strong moral values, exceptional leadership, and strategic prowess.

Reborn as Orion Pax, he embraced his new identity, only to reclaim his role as Optimus Prime to confront the Decepticons led by his former friend, Megatron, igniting the Great War on Cybertron.

Although the character was redesigned to some extent, like the other characters in the film, many classic design elements remain in his robot mode including a predominantly red torso, primarily blue legs, the presence of windows in his chest, smoke stacks on his shoulders, and a head design influenced by the original, featuring the iconic faceplate and ear finials.

At San Diego Comic-Con 06, it was announced that original Optimus Prime voice actor Peter Cullen would reprise his role for the third film.

The three discover a chip among the junk containing a distress message from Alpha Trion, one of the Primes, revealing coordinates to his location on the surface.

Trion shows them the truth that Sentinel betrayed the Primes and has been secretly working for the Quintessons, giving them regular supplies of Energon in exchange for letting him rule Cybertron while removing the miners' cogs to keep them subservient.

While D-16 takes command of them by defeating their leader, Starscream, Orion grows concerned by his friend's increasing aggression since learning the truth.

Orion, encouraged by Elita, rallies the remaining High Guard members and returns to Iacon to rescue their comrades.

While initially horrified, D-16 ultimately lets Orion fall to his death, before he kills Sentinel and then, calling himself "Megatron", commands the High Guard to destroy Iacon.

Following the production of the 2007 film, Cullen reprised his role for the sequels and supporting media and would even voice Optimus in later series such as Transformers: Prime.
