There seems to be a trend I'm noticing here, whenever Meg is brought up someone else brings up the myth or non-disney Meg from Ancient Greece. I think we need to leave the original mythos out since we could keep going back and forth like this until we go stir crazy

So if we go by JUST THE DISNEY MOVIE version of Meg than we need to take these points into account:
- Did she or did she not marry Hercules? In one episode of the t.v series it shows the two of them living together but no hint that they married (unless they did mention it and I forgot)
- Despite Hercules declining (sp?) rejoining his parents on Olympus he still retains his "Prince" status
- Hercules also seems to have retained his God like strength in the t.v series episode with Meg where it takes place after the movie, so he still has his powers as well it seems.
One last thing I want to point out is something SpringHeelJack mentioned about Zeus and Jupiter being King and Queen of the gods. Jupiter is the Roman equivalent of Zeus, so Jupiter isn't a Queen of the gods.
Now onto some characters I've seemed to have missed in my list
Nala - Not in princess list because in LK2 she's the Queen of the Pridelands
Kiara - Same as Nala but is also a Princess for the one movie
Kidagakash - Also a Queen by the end of the movie
Sarabi - Queen in first half or so of the Lion King
Faline - Princess of the Forest due to her relationship with Bambi
Kida's Mom - Only had a couple minutes of screentime but still is a Queen
Lillian? - Aurora's Mother, also a Queen
Evil Queen - Yes despite being a villain she is a Queen
So the only reason I've added these characters is because they had to have come from some sort of royal lineage to be Queen, unless they married but I'm assuming they were of Princess status before becoming Queen
