Moves I want to see:
Gomu Gomu no Drill: Kind of like Gomu Gomu no Spear, which was used against Blueno, but instead of just striking with his feet, he should do what he does for Gomu Gomu no Rifle and wrap his legs aroundeach other for an added spring in his strike. Like an uber-dropkick or something.
Impact Dial Ammunition for Ussop, I've said this before in another thread. If he can open up an impact dial and see how it works, I'm sure he can replicate them. That way even a normal non-fiery shot will do tremendous damage. And I'm pretty sure he was utilizing a flame dial for his shot at the WG flag, so it'd make sense for him to use other dials. I hope that the using of impact dials don't only become Ussop's melee defense, but become ranged as well.
Sanji utilizing kairouseki shoe soles. It might help him fight a logia if he ever encounters one. I'm sick of hearing people say Zoro should have a kairouseki sword. If anyone needs a way to fight logias, it's Sanji. Zoro already has the ability to tune his sword to cut specific things.
Combo moves:
Luffy and Franky: Luffy goes into Gear 3 but instead of using his own breath to blow himself up, Franky does a Coup de Vent into him to inflate him to a huge size.
Chopper and Ussop: Ussop loads Brain Point Chopper into Kabuto, and fires him at and enemy fortress from afar, while in mid-air, Chopper consumes 3 Rumble Balls, making him transform into Monster Point. Monster Point Chopper then lands in an enemy base and pwns them all.
