As far as haki goes i feel like nami, chopper and usopp(already accomplished) should have observation. they dont really need armament haki especially nami because she fights with the elements. Chopper i think would be most likely to get it tho.Well, pretty much every Straw Hat that fights directly has Haki except for Chopper and Franky. I don't know that Robin or Nami particularly need it. Franky probably doesn't either. Oda's probably just going to keep matching them against people that don't use armament Haki.
I suspect Chopper has an Awakened Devil Fruit (it retroactively fits with what we know of the giant form, considering he forcefully induced it via the Rumble Balls and it's similar behavior to the awakened Zoans from Impel Down, but now he can control it)
Franky? Eh who knows his technology gets him thru and im fully expecting sum seastone stuff he has saved.
Robin..ha no chance to broken
Brook.plz o plz o plz!!! Ending of the series brook vs whoever, full body black skeleton
