Except OP people don't have chakra. Thus genjutsu, which activates by injecting ones chakra onto the chakra stream of another (focusing on the head), doesn't effect ANYONE on One Piece.Genjutsu>One piece world
actually that isnt quite true naruto characters deal in elemental attacks, so as long as they use the right element on the right logia they still have a chance like kisame could beat crocodile seeing how water is his weakness madara and other fire users can take on smoker and lava/magma users could take on ace granted there's a lot more to a fight but they do have their ways. also we are comparing two worlds whose to say a chakra infused punch couldn't work like a haki infused punch <---- and im not saying that i believe this to be the case but it is a possibility seeing how they are two opposite worldsEven if Genjutsu were to work on OP characters, Naruto characters wouldn't be able to do diddly squat against Logia characters since they don't have Haki.
One Piece solos.
