Even amongst the weakling trio:
 * Nami showed some very strong moves in Whole Cake by controlling the lightning from Mama's storm and using Zeus later.
 * Usopp is still showing new types of pop green and showed even better marksmanship in Dresrossa. Even developed Kenbunshoku.

But the last new thing we saw from Chopper was on Fishman Island.
