My favorite is a tie between Mercury or Venus, and my least fave is most likely Chibi Moon, but sometimes she has her moments ^^

i love chibi moon

Uranus and Neptune ♥

Oh, I forgot to mention that I don't think Uranus and Neptune are a couple. I think of them
as very close friends who know everything about each other. In the end, there was never a
proof that they are lovers.

I love Sailor Moon the most! My least favorite would have to be Uranus, and for some reason, I've just never liked Venus that much. I'm more familiar with the inner senshi than the outer tho.
