I feel that Lucy has the One Magic inside of her. If that is true then she would be needed when Natsu vs Zeref happens. All in all, I feel that The One Magic is required in order to defeat Zeref. It would make sense since its been hyped up so much and that Zeref is theorized to have connections to it as well.

Also if that (Lucy having One Magic) happens, then Lucy One Magic = Ellie Etherion
