Finally, someone else who has seen the dark crystal. It's the best kids movie ever. I used to watch up to the part where Chamberlain challenges that other guy for the emperor-ship and loses so then they strip him and he's yelling. Then I'd rewind it and watch it again, and then continue to watch the movie. Oh and that bit when he first meets Augrah and she's like, "Questions, questions, too many questions.. if you want a shard.. here!". I loved it.
Actually, all the movies you mentioned were at one stage my favourite movie as a kid. He-man was so good, I used to watch the cartoon every morning on agro's cartoon connection. I had a sword too.
