Ok am I the only one that thinks this was a huge missed opportunity for Natsu to use fire god slayer magic or fire dragon god slayer magic.
Post from the wiki below
Dragon God's Brilliant Flame (竜神の煌炎 Ryūjin no Kōen): An alternate version of Fire Dragon's Brilliant Flame, Natsu engulfs one hand in the flames from his Fire Dragon Slayer Magic, and the other in flames from Flame God Slayer Magic, and brings the two flames together, generating a highly destructive blast that is capable of destroying a large area, and defeating Zancrow, a member of the Seven Kin of Purgatory in one hit.[55]
Since Natsu had been exposed to Flame god magic in the past I think that if it said that he trained during the time-skip to be able to use it at will that he could have gotten a very explainable power-up and with him just fighting a god it would have been the best time to give him the power. I guess Dragon god's brilliant flame will be a one time attack instead :/ Kind of disappointing to me
