This thread asks 'who is the female lead of MOTUC'. That's simple.
Take the Filmation cartoons. Kill Teela. Can the show continue? Yes. I can't remember for sure but there must have been episodes in which Teela did not even appear. Now take She-ra. Kill her. Can her cartoon continue? Nope. She's a lead character. It's as simple as that... :-)
As a Mattel employee? We saw Teela at SDCC twice--once during 200X, once during Classics.
As for the Comic Con BG Teela, well I can remember a She-ra parading in costume at some ancient comic con edition. I think Mattel did 'Battle Ground' teela this year because it would save bucks thanks to the rather skimpy costume she's wearing. :-)
