They did KO that G1 jetfire figure, well... at least the mold; but I think nearly all of us missed the boat. It was by a company called Joon's and from what I was told, those things sold for ~$20-$25 back in the day. The green box was near identical to Takatoku's, but Joon's had, "MACROSS" at the top instead of "BATTROID VALKYRIE." They had that mold in I think 4 variants: blue, red, olive green and the red-white-blue combo. I've since picked up a few of them. The happywell galaxy defender series of toys had the grey valkyrie you're talking about. They have lime green visors and I recall seeing a seller having them with different weapons than the standard rifle that we've seen with other releases. I think I want listed the item w/ sirtoys 2 or 3 years ago. There are also thin plastic, cheap KO valkyries in the 1/55 scale whose legs in gerwalk/guardian mode bend inward and so don't stand straight without some sort of brace. Some even came in the skull leader (roy) colors with a blue jetpack. Seeing these various 1/55 valkyries (aka chunky monkeys) was what got me back into collecting as an adult ~2012, as the G1 Jetfire was probably my favorite toy as a kid... then things spilled over into collecting other things, and now thousands of dollars later, well, you know.
