That would the most hilarious fight in the whole history of manga!
No, that would be if they made it a three way battle royale between Foxy, Buggy, and Afro Luffy.
--------------------------------------------------------------------------------------------------------------------
Gold Roger vs. Whitebeard. This is it. The fight. They fought alot, but I wanna see the one fight that was considered their greatest. I wanna see a legend. I wanna see these two royals among pirates fight at their full strength against the greatest opponent either could find.
Gold Roger vs. Whoever-The-Heck-Captured-Him. Come on. Like you don't wanna know how the Pirate King was finally defeated and brought to trial. It must've been a great fight. Or at least an interesting one, since I suspect that Roger was captured through treachery. I mean, how could you defeat a man like Roger without tricking him?
I also wanna see Shanks vs. Mihawk. Again, let's see if the gap is as huge as everyone says it is. I wanna first see a flashback to the original battle, both to know what went on, and because it was awesome. Then I wanna see how things have changed for them since then. Shanks lost his arm, but still became a Yonkou. Mihawk gained the title of "The Greatest Swordsman in the World" and became a Shichibukai. They've both progressed, but how far?
Those were the legendary fights of yore that I want shown. Now for some stuff in the present time-line.
I wanna see the Monster Trio face off against each other. Let's see if Zoro is really as close to Luffy's strength as people think, whether Sanji's lack of a weapon or a Devil Fruit really makes him weaker then the other two, let's see all sorts of things. I would be interested in that not so much to see who won, but to see how they did against each other.
Luffy vs. Aokiji. All of us saw Gear. I'm almost sure that all of us thought Gear was awesome. Well, Gear was made to defeat Aokiji. Can it do that? Did Luffy discover a way to push his abilities far enough to overcome the best the Marines have to offer? Or are Aokiji and the fist of the Marines too powerful for even Luffy to match and overcome?
Luffy vs. Whitebeard. This I am almost sure will happen, since I think that Whitebeard will be the second to last enemy that Luffy faces. (Guess who I think the last is?) But I'm not completely sure that it will happen, which is why I'm putting it down, because it's a hope. Zoro vs. Mihawk I won't mention, because that's a certainty. Anyway, I wanna see how the rubber-man wonder pirate faces off against a man with so much power and legend that people go catatonic at the mere MENTION of his NAME. (Just think what sort of effect Roger had on people, huh?) Luffy has made alot of progress, when you look at him now and you look at him when he fought Morgan. ALOT of progress. But is it ENOUGH? Does Luffy have what it takes to defeat a man who could not be defeated even by Gold Roger himself? How would he go about doing it? What wildly inventive new uses for his abilities would Luffy come up with? How far can he push his abilities? How powerful is Whitebeard REALLY? I wanna know.
Whitebeard vs. Blackbeard. Alright. So we got the strongest man in the world, and the man most likely to take that title from him. Two men who both seem invincible. Two men with nothing but hatred for each other. This would be one of the greatest grudge matches in the history of grudge matches. Can Whitebeard show that the older generation has not lost its vigor, or does Blackbeard have the strength to defeat the era of yore and prove that the old heroes have no place among the new generation?
Luffy vs. Blackbeard. This also isn't a certainty, but I think it's close to one. Blackbeard, due to his monstrous strength and the demonic abilities of the Dark Dark Fruit, is probably the most powerful character in One Piece. (Seriously, if anyone has a chance of stealing the title from Whitebeard, it's Blackbeard.) How does that strength match up to the strength of one man's dream to become the greatest pirate in history? Luffy is a good fighter even without using his Devil Fruit abilities, but is he good enough? Is his rubber body able to withstand the gravitational force of a black hole? Does Blackbeard's Devil Fruit have even more abilities that he's hiding? Is his monstrous strength even to much for Monkey D. Luffy? Only one of the greatest battles the world has ever seen can answer that.

Well, those are the most epic battles that I wanna see. Later, I might post some of the less-epic battles I wanna see, because they're there. Just not on the same scale as the battles I wanna see between the Yonkou, the Shichibukai, an Admiral, and the Monster Trio. I'm saving that other post for guys like Ace, Dragon, Smoker... The lesser legends.
