As a strong Carrot supporter I feel like I've already said all I can about the character joining so don't need to rehash that. I'd rather like to go the opposite route and point out what I don't really like about her portrayal and honestly is something I think the character can do without. That's the entire thing about turning her a Chopper cheerleader in the first half of Wholecake. It came totally out of the left field and served no purpose at all. And I still think we saw her do the Bropper/Choniki thing at some point in Wano. I can honestly do without a character being another Strawhat's cheerleader in the crew. Sanji get's a pass because he is the same for every woman, not just Nami and Robin. But if I say that Hancock and Bartolomeo would break the dynamic on the Sunny by fangasming over Luffy, then I have to play it fair and say I wouldn't like to see the same thing with Carrot and Chopper.
Eh, I didn't see her as his cheerleader. There was this senpai-kohai relationship, or big brother-little sister, but Carrot was definitely not there to cheer on Chopper as his support to make him look cooler. They were diving the job, and arguably Carrot outshined Chopper in their little side adventure.
We don't have to call her cheerleader. A sempai-kohai relationship is just as it has a clear structure of who's the superior and subordinate. Deviding their work share is doesn't change that as it's an integral part of a sempai-kohai relationship. Personally I prefer avoiding any labels among the Strawhat crew which would remind me of this concept.
