Their relationship could develop through mutual respect. Luffy respects Whitebeard as a powerful and respected pirate, and Whitebeard respects Luffy's determination and potential. For example, they could start with a simple exchange of stories about their adventures at sea.
Yes, there might be. The 'Harry Potter' and 'One Piece' (where Marineford is from) fanfic communities are quite large and creative. There could be a crossover where Harry Potter somehow saves Ace at Marineford. You can check fanfic platforms like Archive of Our Own or FanFiction.net to see if such a story exists.
A 'whitebeard x oc fanfiction' often involves creating a unique story with an original character (OC) in a relationship with Whitebeard. It can explore different aspects like their adventures together, how the OC might change the course of events in Whitebeard's world, or simply their emotional bond. For example, the OC could be a new crew member on Whitebeard's ship, bringing in fresh ideas and challenges.
Whitebeard's speech is definitely fictionally significant. It can reveal his character, motivations, and influence the plot in meaningful ways. It might also stir emotions among the characters and the audience.
Well, he might become more protective. Just like Whitebeard who was extremely protective of his crew, Naruto could start showing that same level of protectiveness towards his friends and the village. He might be more willing to use his power to shield them from any harm.
The unique combination of two very different universes. Naruto's ninja world and Whitebeard's pirate world in One Piece are quite distinct. So, when Naruto is a Whitebeard fan in a fanfic, it brings in a new dynamic. It could be the clash of values like Naruto's loyalty to his village vs Whitebeard's loyalty to his crew, or the different power systems that interact in interesting ways.
I'm not sure specifically as I haven't read this particular fanfic. But generally, it might be about the characters ASL (presumably Ace, Sabo and Luffy from One Piece) being saved by Whitebeard in some sort of alternate story created by the fanfic writer.
Well, Harry Potter might be magically transported to the 'One Piece' world just in time to save Ace. He could use his Patronus charm to fend off the attackers at Marineford. Since his Patronus is a powerful form of positive magic, it could be strong enough to hold off the Marines for a while. He might also use his knowledge of potions to heal Ace if he's already injured. And perhaps he forms an alliance with Luffy and the Straw Hats to help them get out of the dangerous situation at Marineford.
Well, in the fanfiction, Gear 4 Luffy might have had some new and unexpected interactions. Maybe he could have teamed up with some other pirates in a different way. Since he was in such a powerful form, he could have inspired more of the pirates to fight back more bravely against the Marines. And his presence in Gear 4 could have also affected the admirals' strategies, making them more cautious or forcing them to use their more powerful techniques earlier.
It would likely make the storyline more exciting. Gear 4 Luffy is extremely powerful, so his presence in Marineford would change the power dynamics. He could defeat more enemies quickly.
