Look at us pretending to be all objecting and reasonnable in our line of argument... Yet our avatars betray how biais we are! You have a Teela avatar and I have an Adora one!

Begone! Both of us!!!
This said, I don't agree with your arguments.Either we are looking ONLY at the Masters of the Universe Franchise, and thus Teela is the lead, as She-ra did not appear in that series, and the argument is closed. (And that poll doesn't even exist.) Or, and I think that was the point of this poll, we look at the MOTU / POP universe as a whole. And in that case, Teela is not a lead.
You keep saying Teela is like wonder woman, who's the woman in DC's 'trinity'. But if you examine her role in the mythos, Teela is very much a 'Lois Lane', i.e. a love interest for the lead of the hero.
Wonder Woman is the only DC superhero with Batman and Superman that has had her own ongoing comic without any interruption. That's why that 'trinity' is an interesting example.
Teela, as much as we all love her, never had her own comic, her own series. She appeared in the He-man cartoon but never without her 'lead', He-man.
Just like Lois Lane appeared in numerous comic books but she never sustained her own comic!
Another indication that Teela is not a "lead" is the fact that usually, in a series of comics, the lead is the superpowered character (when there is one). Love interests are usually (emphasize on 'USUALLY" I know there are exceptions!) powerless. Teela is a trained warrior but has no magical powers or superstrength, just like Steve Trevor, Lois Lane, Mary Jane Watson etc. etc.
Now I know she is destined to become the new sorceress, but she never obtain such status neither in the original comics nor the cartoon.
She-ra is very much like Wonder Woman because she is the main character of the series. She has powers that set her above mere mortals. She is the lead in her own series 'She-ra Princess of Power', she even had a movie made just for her introduction, as someone pointed out. She is a "lead".
You may post as many Teela cosplay figures as you want, it won't prove anything else other than what we already know: Teela is loved like many other characters of the series. If I find pics of people dressed in Trapjaw cosplay costume, it doesn't make him the lead of the series!
