Ok...well I know it's Optimus Prime. But what the hell is he? I got him in a bag for 20 bucks. Seems to be perfectly fine. has A MILLION things that came with him. He's made of metal? Well he's heavy. His transformation seem flimsy. (Arms and flanks) But I see no stress marks on him. Truck mode is meh. I have yet to be able to tab everything together. Robot mode it awesome. Seem it even have a tiny tiny matrix (which i have yet to be able to pull out). So....what is he?
