And yet, as early on as these are it's very clear what these figures would become. We've got an Optimus Prime sporting a samurai-looking helmet along with some attempts at a trailer including a shot at the trailer that would later belong to Ultra Magnus. We also get to see Grimlock, Motormaster, and Metroplex among various Autobot cars. But what's very special is the prototypes that never became figures. Next to a rough attempt at Soundwave we have several unproduced tapes including various insects, a sabertooth tiger, and even a horse! There's also a Triplechanger that turns from robot, to tractor, to seaplane! And the biggest of all is a 5-changer that can turn into a robot, spaceship, tank, aircraft carrier, and what appears to be a train! How cool would that have been in the '80s or even 2019?
