I think Teela is one of if not the most debated character in MOTU and the debates are no short of epic. My thoughts on Teela, even going back to the early 80's were reflected best by MYP so I go with them in my cannon. With that being said I still love the mystery of the whole topic.
The Monkey King Sun Wu Kong aka Son Goku was born from a stone egg. It's one of the things that made him special.
