I think there were periods of time in which there was no He-Man and the both parts of the sword were hidden somewhere on Eternia by "the goodess". In case that some evil powers were searching for the swords or in the case that the swords have to be removed from the cache a new He-Man was needed.
The He-Man in the picture above isnīt Adam, but he wears the same techno vest as Adam (inclusive shoes)...was he living before Adam? No, because in MotuC Bio of He-Man they say "At first, he used a techno vest with a built-in force field...". So this guy live years after Adam???
Or was he living before Adam wearing the same vest but without "build-in force field"???
When this is true, there must have lived minimum one other He-Man before this guy above wearing the same vest.
How many He-Man before Adam were wearing this vest?
Vikor and Wun-Dar have their own styles, at some point in time the He-Man begin wearing all the same vest!?
I am wrong?
