I don't get why Franky should get Sea Stones fist.. While at it, give him fist made of Poneglyphs if there's another stonemason like Oden around or he left the Knowledge in his journal..
I think seastones weapons are more suited for people like Hawkins and Usopp by shooting projectiles..
Luffy
Already acquired power up
- Avanced CoA
- Avanced CoC
I think he need one more power up to defeat Kaido
- Awakening
Zoro
- Upgrade Sandai Kitetsu to Nidai somehow
- Conciously control or awaken his CoC
- Avanced CoA internal destruction
- Tap in Wado Ichimonji's powers
- Master Enma
- Elemental powers of some sort
I don't think Zoro will turn one of his blade black this arc..
Sanji
- Awaken his modified genes power
- Advanced CoO( not future sight)
Jinbei
i think he not only used full body hardening but as well basic Advanced CoA
He has more secret Ougi techniques and he i believe he will utilise a version of Seimei Kikan, perhaps not in Wano, eventually..
Franky
- A new version of Coup de Vent similar to Kuma's Ursus shock
- CoA
- Something related to electricity, an Overload mode, i don't know
- New body transformation
Robin
- Giant version of herself
- Mastery of her devil fruit( not awakening close)
Brook
- Awakening
Maybe his soul can take real form similar to Hawkins Straw man's card, the thing that was chasing Zoro and Luffy.. Another wild speculation is you could see his devil fruit abilities as an imitation of CoC, he's affecting other people's spirit, so maybe Brook can imitate a version of Advanced CoC by coating his Soul over his Skeleton, like an armor..
Chopper
I have big expectations for Chopper, i hope Oda will do him justice..
- 2 new forms by distorting the wavelengt of Monster point
- Mimicking abilities from the Minks, per floating, electro and sulong speed
- People suggesting Ice Oni based point that's interesting too
Chopper must have a 1v1 this arc.
Usopp
- Sea stone projectiles make more sense for him
- His exploding pinecones attack was very powerful, its underestimated i think
- Imbuing CoA into his arsenal
- 1 ton Hammer finisher attack
Nami
- Already got Zeus, that's enough
