Ahhh, now THIS is a death battle. One of my favourite kinds, in which no one can really agree on who would win, right up there with ones like Hulk vs Doomsday or even Mega Man vs Astro Boy. I love it. But I've still managed to make my choice.

The fire stuff will be the bulk and the biggest factors, so let's get everything else out of the way first.

Natsu is pretty strong, bending iron, punching a guy who's basically made of iron, and lifting what I've calculated to be nearly 3 tons of...you guessed it. Wood. As a quick reference, here ya go.

While it's hard to find actual feats for ace, what little he does have goes much farther than what Natsu has done. A simple arm wrestling context with Luffy proved Ace was equal to his younger brother who, in what would've been less than a month, went on to lift a 300 ton ball of gold, at bare minimum. Now it is safe to assume Luffy got stronger during that short time period, even if we lowball it and say Luffy was half as strong when he tested fists with Ace, that's still a massive difference in strength since. In fact, when Ace only 10, he cut down a tree roughly worth the the wood we saw Natsu lift with a single kick. TIMBER!!! And that was 10 years before his prime.

In addition, while Natsu has been a great team player for Fairy Tail, one of the most famed guilds, Ace's superior intellect and experience has made him one of the leaders of the Whitebeard Pirates, one of the biggest threats to the World Government.

But that's all small patatoes? isn't it. What you all want to know is this: How does Natsu's Fire Dragon Slayer magic work off of Ace's flame-flame fruit? THIS is the million dollar question. Even the destructive potential of both fruits seem moot, as both have enough of an outpoot to cloak an island. Time for the fun to begin.

As you know, Ace's body is able to turn into fire upon will or when taking a hit, allowing him to ignore any damage, as how logia devil fruit works. This weakness can be bypass outside the One Piece universe if hit by an element that can counter the user's own. In this case, elements would include water, ice, and lava since it's superior to fire. Natsu has his own fire and even lightning magic, but neither one is an element that can actually neutraulize Ace's devil fruit.

Now Natsu HAS been anble to physically hold, grab, or otherwise touch fire like it was a solid object. While this would mean Natsu would have a way to grab Ace when he becomes fire, that still wouldn't give him a way to physically harm Ace. Fire isn't actually a solid object that you can break after all.

And now the biggest question: Can Natsu eat Ace? The answer is...kind of. This alone has 2 major parts, both of which are important since this WILL have an effect on the fight.

1. Infinite fire vs Natsu's stomach: Juat like with all other logia devils fruits, the amount of fire Ace can create from his body has no actual limit, and it doesn't actual drain any stamina. And much like all typical anime protagonists, Natsu's appitite is hard to sate. While it's hard to say if there's a limit to how fire he can eat, what I do know is that there's a limit to how much he can actually swallow.

During Natsu's fight with Atlas Flame, a fire dragon who had fire covering his entire body, Natsu's strategy was a predictable one: Eat him. He spent a good amount of time swallowing the never-ending flow of fire coming the dragon, becoming more of an annoyance than an actual threat. In the end, Natsu stopped eating no harm at all was caused to Atlas. As the amount of fire Ace can produce is potentially limitless, Natsu wouldn't fair any better against him.

2. When fire meets: Now both Natsu and Ace have control of all fire that they themselves make. Also, whenever Natsu eats a source of fire, any special properties that fire had is kept as Natsu uses it for himself. It's the good ol' Mirror Force tactic of using your enemy's power against them. But really consider this: What would happen if Natsu actually allows his fire to be mixed together with Ace's? The answer is actually quiet brutal. With a literal piece of Ace inside of Natsu's body, and all mixed together with Natsu's attacks, Ace would in turn be able to control all of that fire since it's now a part of Natsu's, and unlike the first time around, Natsu wouldn't be able to re-eat it all. This is an inevitiable outcome since Natsu thinks with...well, as we discussed with his fight with Atlas Flame, he doesn't think that much. This would be a detail Ace would no doubt exploit as he's actually quite intelligent.

Overall, Natsu's dragon slayer magic, ironically enough, feeds into Ace's devil fruit powers much more than the other way around, creating a back and forth fight of fie that eventually comes to Ace's favor as Natsu eating his opponent is in fact the worst thing he can and would certainly do. And as Ace already holds his own in stength and strategy as well, the rest of the fight is fairly clear-cut.

This was a long one for me to write down, and just like Natsu, I'm burnt out. And so, The winner is Portgas D. Ace.
