I always thought Robin was my favorite too, but now I wonder if I was doing the same thing I was doing when I crushed super hard on Marceline, which is like...romanticizing mental illness I guess? Romanticizing depression/being sad? And "being mysterious", which like, just means you don't know anything about them. When in reality they might be boring if you ever learned! Recently I think I might just like Nami more. She's a little less unique design-wise, and she doesn't have cool weird arm powers but she has such a strong personality and characterization, which I think I'm beginning to prefer over moody/mysterious people.
She feels more 3D cus we see a variety of personality traits in diff situations. She can be funny, serious or ethically dubious, and she's also a surrogate for the audience like Usopp so she's very relatable. Plus she's the de facto "mom" of the group, not because she's especially responsible and reasonable, but because EVERYONE ELSE is either too stupid, naive, or apathetic to be the voice of reason and restraint. I do like that post Ennies Lobby Robin seems a lot happier and self-assured, and I dig her chill, laid back demeanor, but often feels like she doesn't have a whole lot of reason to be there character-wise, apart from being the "oh, her bit is to say something creepy" member of the crew.
This pic is definitely sick, on the other hand, and hell yeah keeping her dark skinned.
