CORRECTIONS: Thank you microbry and geotroid. Microman is not an area I’m super familiar with so I’ve corrected my, ahem, mistakes.
Grandstand Toys made quite a few Micronaut like toys that were licensed to them by Takara, much like the Micronauts themselves were licensed to Mego. I never encountered them as a kid, but thanks to the magic of eBay, I’ve managed to run across a few.
A reader sent in these pictures of the Deltarian Figher. I initially thought it might share some parts with a Giant Acroyear, but it turns out this is actually a Microman toy repackaged for North American consumers. The figure it comes with is a 1982 New Microman M-11 Salam, which I also initially thought was a Pharoid. According to microbry, the only real difference is no GITD chestpiece with a pharoah face on it. So I wasn’t too far off. There were a couple of different releases of this set in English, including some by Takara themselves before the Transformer license came along.
Geotroid added there were in fact knock offs, which I have seen, so that is why I probably assumed this was one as well.
I love that the Convertors tag line is “Nothing is what it seems!” You can see it getting closer and closer to “More than meets the eye!”
