While the Headmaster gimmick would have been cool on the original Powermaster Prime, I'm kinda glad he didn't end up with those Micky Mouse wheel ears.
Ah budgetary constraints always keeping Hasbro from greatness.

This is where I store my Powermaster Optimus Prime's head. As you can see, it's a really small space, and it'd be a far more snug fit if this head had wheels protruding from it and could fold out into a Roller buggy mode. I think that this space was designed to be just big enough to hold Roller, and not much else. It doesn't seem to be big enough to hold any of the carded 1988 Autobots (e.g. Throttlebots, Triggerbots etc.). The space doesn't do anything for the robot or base mode; it seems to serve no other purpose other than to hold Roller. And of course, it even has a ramp for Roller to roll up and down from.

It was a brilliant and ambitious concept but i am happy Roller-head was dropped from the final version as the manufacturing was not at a level to somewhat hide the wheels and make it look any good.
On the other hand a Roller that was also a good looking Optimus head AND could be driven around base mode by Ginrai would have been the bees knees.
I've been away from the boards for a while.....
Wowowowowowowow!
Just love this Prime (even if just a headmaster)
