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.
For Doflamingo, you can focus on his flamboyant and unpredictable nature. Show his sadistic side in how he deals with enemies, but also explore his more vulnerable moments, like when his plans are thwarted. For Crocodile, emphasize his cool and calculating demeanor. Let his past failures fuel his actions in the fanfiction, like his determination to regain his lost status. Maybe show how Doflamingo's chaos sometimes clashes with Crocodile's order.
One character that would make for an interesting pairing with Doflamingo in a crossover fanfiction is Zoro. Zoro's strong sense of justice and his skills as a swordsman would clash with Doflamingo's devious ways. They could have epic sword battles, and Zoro might be the one to cut through Doflamingo's strings, both literally and metaphorically. Also, Nami could be paired with Doflamingo. Nami's intelligence and ability to manipulate situations for her own gain, although in a more positive way compared to Doflamingo, could lead to some really interesting interactions. She could try to outwit him in a game of wits.
I really like 'Doflamingo's Unseen Side'. It presents a different perspective on Doflamingo. It has a lot of action scenes and also explores his relationships with other characters in the One Piece universe in a unique way.
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.
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.
Another plot could revolve around an OC who is a former victim of Doflamingo's cruel rule. This OC could be on a quest for revenge. They might start by gathering allies who were also affected by Doflamingo and then plan a elaborate scheme to take him down. Along the way, they could face many challenges and obstacles set by Doflamingo and his loyal followers.
Yes, there might be such a fanfiction out there. The world of fanfiction is vast and full of creative crossovers. Some writers like to mix different anime universes, so it's possible for someone to write a story where Naruto, from the Naruto universe, is a fan of Doflamingo from One Piece. However, it would be quite an interesting and unique take on both characters.
Well, it depends on what you consider 'good'. In this kind of fanfiction, authors might take Harry's backstory from the Harry Potter series and blend it with Doflamingo's world in One Piece. They could create scenarios where Harry has to navigate the political intrigue of Doflamingo's domain using his own set of skills. But it also might be a niche genre, so not as widely available as more common fanfictions. You may need to be patient while searching for quality 'Harry is Doflamingo' fanfiction.
