Native America is the mother of all the tribes of her land. All of them. Each and every tribe has their personifications but they are her sons and daughters. She is not them. But is their mother. AKA this is my solution to the whole "native America being one person is an insult" which, yes it is, but this is a fix (maybe).
Also Canada And America are full brothers, being from their mother with no father needed. However Mexico is the son of the Aztec empire (or at least adopted son, IDK). I am not saying that Mexico is just like the Aztecs but simply Aztec took care of Mexico until Spain came in and killed him and took 'custody' of Mexico.
