Since a lot of members are into various 80s toylines, figured it was worth sharing this tidbit on the MOTU line and the undocumented He-Man promotion often known as "Wonder Bread" He-Man:
ToyGuru goes on a whole long thing on this, so I suggest skipping to 11 minutes in.
Long story short, there was a "Buy 3 Get 1 Free" mail-in promotion that Mattel ran in 1983 for a few brands, and the figure received if you were getting one from the MOTU line was a barebones alternate version of He-Man with brown hair and a couple weapons at most, no armor or anything else. Lends some credence to the thoughts on how certain rarer MUSCLE figures may indeed have been store-exclusive inserts or something, if Mattel was so bad at documenting a promotion like this. In any case, cool reveal at least!
