ace at marineford

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.

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.

If Naruto arrives at Marineford, it would be a chaotic and interesting scenario. Naruto's powerful jutsu like Rasengan and his ability to summon toads could change the balance of power. He might try to stop the fighting between the pirates and the marines, seeing the senseless destruction. His sense of justice and never - give - up attitude could inspire some of the characters there.

Luffy and Ace's interaction is always key. In fanfiction, it could be that Ace reveals a secret to Luffy right before the final battle that gives Luffy newfound strength. Another great interaction could be between Luffy and Garp. Garp might be conflicted between his loyalty to the Marines and his love for his grandsons, and this inner turmoil could lead to some really emotional and tense moments when he interacts with Luffy at Marineford.

One consequence would be a major shift in the power balance in the One Piece world. The Marines would be severely weakened, and pirates might become more bold. Another consequence could be that Naruto would become a huge target for both the remaining Marines and other powerful forces in the One Piece world.

In a fanfiction where Naruto destroys Marineford, it could be due to his overpowered jutsu. Maybe he uses his Rasengan in a super - enhanced form that creates a massive explosion, leveling the Marineford. Another possibility is that he uses his Sage Mode to outmaneuver all the opponents there and then unleash a devastating attack.

One idea could be that Naruto characters are somehow transported to the Marineford world. For example, Naruto with his powerful jutsu might get involved in the battles at Marineford. He could use his Rasengan against the powerful foes there. Another idea is that the Devil Fruits in the Marineford world have an interesting interaction with the chakra system in Naruto. Maybe a character from Naruto eats a Devil Fruit and gains new and unexpected powers.

One possible plot development could be that his death shatters the Straw Hat crew. They might disband in grief, each going their own way. Zoro could become consumed with revenge, vowing to take on the Marines who were responsible.

Naruto would be very curious. He'd want to understand what's going on. Once he figures out that there's a big battle between different factions, he'd try to find a peaceful solution. He might start by talking to the leaders, using his charm and persuasion skills. If that doesn't work, he'd use his ninja powers to protect the innocent. He's not one to just stand by when there's injustice.

Ace could be an anti - hero in the 'ace loses control fanfiction'. They have their own set of beliefs and values which might be different from the mainstream. Losing control could be a turning point for their character arc, either making them more of a villain or pushing them towards redemption depending on how the story unfolds.
