The Mabamex Battle Armor He-Man has some variance in both head consistency (Hard Rubber Head, Semi-Hard Rubber Head and Soft Head) and some minor color shifts/changes. What stands out though with this particular figure are the weapon variants.
Most weapons for this figure were made in the USA. You can see this when reading the card back “FIGURE MADE IN MEXICO. BALANCE MADE IN U.S.A.”. Still, there has been a set of rare weapons marked MEXICO that were also made for this figure. Those weapons are almost identical to the USA-marked weapons with slight color changes, with the difference in that they are marked MEXICO. Not to be confused with Aurimat weapons that are also marked MEXICO, but that are a completely different mold, color and plastic. These (MEXICO marked) variant weapons can come stamped either with a 1 batch number or with a 2 batch number.
It is unclear to me at what point these variant weapons were released (only time will tell), but my theory is that they were early releases while the production was still adjusting.
