Let's try the Strawhats now.
Luffy
Not really much I can add to a Shonen Protagonist, he ticks all the boxes and followed the same path, nothing is really that different.
Zoro
He takes his role the most seriously to the point where you wonder what his end goal is, the current chapter being crucial to where his next stage of development will be.
Nami
Were starting to see a more capable Nami who may yet prove to be one of the stronger members of the Strawhats.
Usopp
Usopp's journey up to now has been the best and peaked at the God Usopp part, he may yet become the great warrior of the sea.
Sanji
We finally saw some background to Sanji Vinsmoke, pity it was in such a disappointing arc. Nevertheless he now looks more sympathetic.
Chopper
Chopper is the only one that hasn't really changed that much, his impact on the story is getting less and less especially when Trafalgar Law has done more to aid Luffy's injuries in recent times.
Robin
I'm eagerly awaiting the next chapters to see if she can reveal the true history if the world. Definitely a character that could easily win more points.
Franky
His appearance and abilities are keeping him more interesting than his actions. Likely won't get another major role unless Sunny needs a serious upgrade.
Brook
I always found Brook's position to be token but he is proving to be quite formidable especially in the previous cake arc but I doubt he could repeat this.
Jinbe
Showing some great swag standing up to the series top villains but I'm still waiting for his position to be permanent.
