In the NES game Mega Man IV (from 1991, BTW), one of the bosses, Drill Man, seems very reminiscent of a Transformer (pics below), but I can't seem to pin him down. Whenever I see Drill Man, it conjures up a hazy memory of a toy from waaay back when ('80s). Something seems especially familiar when he transforms into the drill tank. And the color, a lot of red (maybe with black) in association with the drill plus the drill being on his head in robot mode. Nosecone of the Technobots instantly came to mind but the color is all wrong and the drill tank form looks all off (not a solid block, back narrower and raised), not to mention no drill on the head. (1970s earth-toned color scheme also anything but matches what I vaguely had in mind) Next thing that came to mind is that mail-away Powerdasher. But the colors are off, the tank form doesn't seem right (drill deeply recessed). What I vaguely had in mind was much more streamlined in form that this Powerdasher. Hmmm, is there some GoBot that looks like him? Or perhaps another transforming robot knockoff from the time? Anything drill-tank + red come to mind?
