Theory Did Oda foreshadow King's race?

[Kiiro]

​

At the bottom, over the left there is 1 face of another character. This meant that there werent 3 species with wing, but 4.

 

[Warchief Sanji D Goat]

1. Lunarians
2. Skypieans
3. Shandians
4. Birkans

All of them have connection to the moon.

 

[Herrera95]

Not Lunarians as we know now but possibly just a new race yet to be discover.
