@Godisme That's a joke, stating that Acnologia would be no challenge. Natsu has become leaps and bounds stronger but hes still hasnt shown anything that would put him on the same level as the Top Tiers of FT.

Acnologia's breath was capable of destroying an entire island, Natsu has a long way to go.
