Based off the upcoming game, this representation of Optimus Prime is in my opinion the best I have ever done, and is a huge step-up from my WFC version.
About this creation
The vehicle mode is compact, and I think decently replicates the whole “fist on wheels” description.
Big bumper on the front.
Has tail lights on the back.
Close-up of the front section.
The gun can peg into the smokestack for “storage”.
Robot mode is highly poseable, as demonstrated by this “running and shooting” pose.
His back.
Both arms are identical, gun can peg into either side, and the side panels hide his hand.
The head is simple, but I think it’s alright.
The gun itself. Based off of Prime’s rifle.
Overall, I think he fits the animation model decently, and looks imposing, at least for his size.
