What if Optimus Prime had a beast mode instead of a vehicle mode?
I went w/ a lion, "king-of-the-jungle", "king-of-the-road", y'see? The colors were a pain to figure out, 'cause lions are mostly orange-y yellow, not red and blue. I threw in some silver/grey fur to mirror Prime's blue zones, and to make him look 'aged' and 'wizened'. I was also trying to match the color layout and flame tattoos on the movie-verse Optimus Prime. Most Beast Wars characters (at least in Season 1) have two main colors, one for the beast mode, and one for the robot mode, but I cheated and used two for each. I tried to keep the transformation the same as the G1 Prime: eyes/windscreen, snout/grill, back legs/back wheels, etc.
