Re: Timsekip Zoro > Franky Timeskip
All of you above me are wrong.
Franky´s Iron Pirate is made out of Wapometal (remember Wapol from Drum Island ?) Something Franky found Blueprints of in Vegapunk's lab. He even said something along the lines that even the genius Vegapunk wasn't able to finish this yet.
Normal pacifista are made out of a metal stronger than steel but not wapometal.
So this places Wapometal above Pacifista metal in terms of durability.
I'm not saying that Zoro can't cut the Iron Pirate since Baby 5 was able to pierce it with her last effort, but you have to give Franky some extra credit here.
He currently build the strongest Robot in the series, that is also capable of transforming because it is a shape-memory alloy that can be restored to its pre-configured shapes, being used to create merger modes in the components of the Iron Pirate Franky Shogun.
So probably Zoro CAN cut it, but it won't be a cakewalk like some of you are saying.
