My theory for why Optimus looks different than the others is because Optimus would probably be like Jesus, a birth that confuses others, as I imagine Prime would've been born from the essence of Primus himself, whereas the other primes may not have necessarily been created in his image. Just my head canon though. At first glance, Optimus Prime in Transformers: Rise of the Beasts may not seem too different from his previous live-action Michael Bay movie iterations, but a close look at the details in his design and movie storyline suggests he has changed significantly.
Set nearly seven years after Earth became a shelter for Autobot refugees in Bumblebee, Transformers: Rise of the Beasts introduces. Anyhow, do any of you guys do this? Did you notice that in Dark of the Moon, Optimus' abdomen looks different from the way it looks in the first film and Revenge of the Fallen. Here are two pictures to show you the difference: Design used in first two films Design used in Dark of the Moon What's the explanation for this difference? Optimus Prime was created as the last of the Thirteen Primes, the first generation of Transformers, each created directly by Primus as a band of unique warriors to combat and defeat Unicron.
Prime has cycled through many different looks over the years. That's why we're honoring him today in our Many Looks of Optimus prime feature. Although they are of the same spark, is the first Optimus Prime that fought in the first war of the Thirteen Primes against Unicron and the second Optimus Prime who led the Autobots against the Decepticons considered to be one and the same, or are they two different entities, both empowered to be a Prime by Primus, both sharing the same name.
Even with these different alternate modes and their varying designs, Optimus Prime's robot mode almost always looks the same. Likewise, be it a firetruck, a semi-truck or a Cybertronian vehicle, Optimus Prime is always ready to transform, roll out and light the Autobots' darkest hour. Optimus has a different look in fall of cybertron compared to war for cybertron while Megatron is still in his wfc body as wee in chap2 and 3 of fall before his encounter with metroplex Remeber in chap8 of war when prime,Ironhide and warpath go to the core and it gives Optimus the matrix? Optimus began training with the other Primes in the Realm of the Primes, who began testing him in preparation for a new mission on Earth.
In one such test, Micronus served as Optimus Prime's mentor, and Micronus challenged Optimus to climb a hill. Optimus Prime is who most people think of when they think of Transformers. But there's a lot of things that people just don't know about him.
