You're a lost and abandoned human in Equestria. If you were to choose from

The Mane Six
Royalty

To adopt you, which category would you pick, and which pony from said category would you want as a parent(s)

main six fluttershy or luna

In all honesty Luna. Second choice I was have to pick would be Applejack.

1675752that, or perhaps Ms. Sparkle

Luna.
No doubt, Luna.

1675797 wait alicorn or not

1675801 hmm.... Probaly pre-alicorn

1675737 Luna, because I am already nocturnal and the fact that I would continue being so if Luna was my mother is awesome :D

I will have to agree with everyone and say Luna.
Fluttershy would be a good choice too. She seems like she would be a good mother, and she has experience with a wide variety of creatures so she should be able to care for a human.

1675737 Either Fluttershy, Rarity, Rainbow Dash, or Applejack.

1675737 i'd want rainbow dash or fluttershy because knowing i can protect them with my ''stare'' makes me smile knowing their safe

Either Celestia, Luna, or Twilight
