There's really no way I see Natsu losing this fight, at all tbh.

Even if I try to say that Natsu and Ace are even in speed and DC (which honestly depends on how you scale and which calculation of Erza's meteor feat you believe since there is MULTIPLE of them), no doubt Natsu trumps Ace in physical strength. Most of Ace's best DC feats come from his flames, not really from his physical strength. Basically what I'm saying is, without fire, Natsu shows more feats of physical strength (which are better overall) compared to Ace. Also, if you do accept the high end feats for those Erza calcs and believe Natsu scales, then Natsu has a pretty comfortable speed and DC advantage over Ace (sub-rela and country bro)

While both Ace and Natsu should not be too affected by each other's flames (via Natsu's fire consumption and Ace's fire body), only Natsu has abilities that are not fire based. Lightning!

Now most people just give this to Natsu because he can eat Ace's fire body (which he totally can depending on the circumstances), however let us assume he can't. Let's say Ace moves faster than Natsu can eat, does this mean Natsu has no way of killing Ace?

Even if Natsu couldn't eat Ace's fire body, he can still attack it. Remember how Natsu was able to get on top of and grab Atlas Flame, a dragon composed of fire and was capable of resisting physical and non physical attacks similar to Ace? Yeah

All in all, due to his superior strength, ability to harm Ace's fire body, lightning, transformations that increase the gap in physical strength even further, and the fact that he can convert Ace's fire body into magic once eaten, it looks like Natsu will actually get a Fairy Tail ending.

It'll be a good fight but at the end of the day, Natsu will be Ace's E.N.D (get it?). The winner is Natsu Dragneel
