Through out the Transformers meta-verse, the many incarnations of Optimus Prime have been mostly transport trucks. But in a few, we see that he's taken on an alt mode of a fire truck. My question, fans... Your choice: What would make Optimus... Optimus? Would the heroic factor of the Fire engine be more suited for the Autobot leader? Or do you absolutely love the Geewunny goodness that is the Transport truck? Leave your opinions. I'm really curious. For me, Cybertron Prime really does it. I mean... Transformers are sentient, futuristic machines. And being the leader of the HEROIC Autobots, the futuristic fire engine depicted by Optimus in the Cybertron series really hits it home for me than any other design.
