Optimus Prime Coat of Arms
So, I've discovered the world of heraldry. It's basically logo design with a formalised programming-language-like descriptive language written in Anglo-Norman French (the Blazon). Right up my street!
Turns out you don't have to be real to have a coat of arms. In the past they have been granted to fictional figures such as King Arthur and Satan himself (considering the enormous range of symbolism for the dark lord I feel they could have done a better job than three frogs on a shield). So I feel entirely justified in offering this design as a possible heraldic achievement for the original leader of the Autobots, Optimus Prime.
Blazoned: Argent, a bend Argent fimbriated Azure. Atop the shield, a helm mantled Azure and doubled Gules and from a wreath Gules Azure an Autobot insignia Gules is set for a crest. To be carried in an escroll below the shield the motto: "plus quam oculo conspicitur" (more than meets the eye).
