Back in the old days authors didn't know how anything worked and there was no Internet to look things up and no budget to do research so they were forced to make a lot of the stuff up on the spot. In retrospect a lot of those choices were weird and often blatantly unscientific, but they worked in context.

I sometimes wonder what He-Man would have been like if they had spent more than 5 seconds coming up with character names and concepts. The whole universe feels like a rough draft/outline where someone went "we're out of budget, this goes into production as is."
