I recently dug up one of my childhood story books, about the Transformers. It was a Marvel Books publication, about 10 by 10 inches, paperback -- the same size as some of the He-Man Golden Books that came out back then. (Marvel Books also did a Fantastic Four story that I have.) He-Man artist Earl Norem did the art in it, and he also did another one I have, which is the origin story. This one is about the Autobots wanting to win a road rally, because the prize is oil and gas, and the Autobots are basically homeless people who beg for food. The Decepticons try to stop them, of course, and things get pretty vicious. Frenzy destroys a bridge, Hound blows up real good, and Optimus... well, I'll let these three pictures tell the whole story. Warning: Optimus Prime has a mouth. It's frightening.
Just so you know, the evil-looking car Optimus is hitting with a telephone pole is being driven by none other than Megatron. Just in case you thought Prime was knocking his human competition into the stratosphere.
