My theory is: Gray will not be the one to save humanity. It will be Natsu.. Like in mythology, when the Pandora's box was opened when chaos and everything evil escaped and spread throughout the world. The only good thing that came out was "hope". Natsu signifies that hope. Like Jellal said in the Oracion Seis arc, he remembered a hope named "Natsu".. Also the phrase "key of hope". Lucy is the "key" and Natsu is the "hope"..
