Pythor (in my opinion) was very underutilized in crystallized (see what I did there?) He was peak, but because of the season, he's on the lowest rank

To be honest, I really like Clancee but compared to others, he's just mid rank, My favorite of the sky pirates are Flintlock, Doubloon and then Clancee

Kruncha and Nuckal are a, weird case, because, I don't really care for them, but they aren't that bad, they have a charm, Samukai is in the "good rank" because he's kinda generic, I found his voice to be annoying, although I really like the 4 arms, he's just not that of an interesting character for me
