Born as Orion Pax, he started off as a police officer with a strong sense of justice. Willing to uphold the law, yet stay true to his ideals, even going so far as to stand up to the corrupt Senate. Eventually, he was known as Optimus Prime after obtaining the Matrix of Leadership and became a great and powerful military leader who led his fellow Autobots into war against Megatron and his army of Decepticons. He is revered by many and reviled by some, but always carries a strong presence with him no matter where he is. When Optimus was Orion, he was still a bit green, reckless, and short tempered, letting his emotions get the better of him. More inexperienced, before gaining wisdom through the Matrix.

If you are cast, you will have a LOT of recording to do, so keep that in mind before trying out. While I don’t expect a full-on imitation, I would like something similar to our previous Optimus, given that he’s already made his debut in the series. For reference, please listen to the Death of Optimus Prime one shot here: https://www.youtube.com/watch?v=wfVW_A9-TwE&t=314s

When he’s still Orion Pax before the war breaks out, he should sound slightly different in comparison. A bit younger than he is when he’s Optimus. Perhaps similar to Gary Chalk’s portrayal, though that’s open to interpretation.
