Remember that the
original
So the 'headmaster' gimmick is actually a nod (heh) to Powermaster Optimus Prime's original head-gimmick concept. This is what Ono Koujin originally wanted for PM Prime/Super Ginrai, but was pipped at the post because the budget wouldn't allow for it. Hasbro's budget was even smaller than Takara's, hence why PM Prime is basically a cheaper version of the Ginrai toy. Godbomber (and thus God Ginrai) was originally meant to be
a more complex toy too, but again budgetary constraints meant that this prototype was never mass produced and the
final product was just a shadow of what could have been.
