Yes, there might be. The Harry Potter and Naruto universes are both quite popular, and many fans like to create crossover fanfics. You can try searching on major fanfic platforms like FanFiction.net or Archive of Our Own. Just type in relevant keywords like 'Dumbledore Naruto crossover' and see what comes up.
In this fanfic, it might start with Dumbledore somehow learning about Naruto's world. He realizes that Naruto has qualities that the wizarding world lacks. So he hires Naruto to bring in a new perspective. Naruto could introduce new combat techniques, and his positive attitude could inspire the students. He might also face challenges in adapting to the magical world, which could add a lot of interesting plot points like trying to understand how magic works while still relying on his ninja abilities.
The plot could be centered around Dark Naruto hiring Tsunade for a secret mission. He may need her to revive someone important to him, someone who could be used for his dark purposes. Tsunade would be conflicted as reviving the wrong person could have dire consequences. Meanwhile, as they work together, Tsunade starts to understand the root of Dark Naruto's darkness and tries to heal him from within, leading to a complex web of relationships and power struggles.
Yes, there might be. In the vast world of fanfiction, all sorts of creative and unexpected scenarios are explored. Some authors might come up with the idea of Dumbledore being afraid of Harry for various reasons. It could be due to Harry's newfound power that he doesn't fully understand, or perhaps a prophecy that takes an unexpected turn in the author's interpretation. Fanfic writers often like to play with the established characters' emotions and relationships in unique ways.
Sasuke could be a likely candidate in a sense. Given his skills as a ninja, his Sharingan which gives him an edge in combat and perception, and his past as a sort of 'rogue' ninja. He could be in a situation where Naruto has to hire him for a special mission that requires his unique abilities. Another possibility is Kakashi. He has a vast array of skills, is very intelligent, and could easily take on the role of an assassin if needed, even if it goes against his normal moral code slightly. He would do it for Naruto's sake.
One possible reason for Dumbledore lying in fanfic could be related to his own past mistakes. He may have thought that by not telling Harry everything, he could guide Harry more subtly towards the ultimate defeat of Voldemort. However, this often creates a sense of betrayal for Harry in the fanfic, which adds a new layer of drama to the story.
Yes, there might be. The Harry Potter fandom is vast, and there could be fanfics with all sorts of creative and sometimes controversial plotlines like this. However, not all such fanfics are easy to find or of high quality. You'd need to search on popular fanfic platforms like Archive of Our Own or FanFiction.net.
Some fanfictions portray Dumbledore negatively because he made many controversial decisions in the original series. For example, his handling of Harry Potter's situation was sometimes seen as using Harry as a pawn in the fight against Voldemort. He kept many secrets from Harry that could have potentially changed the course of events and put Harry in more danger. Also, his relationship with Grindelwald in his youth and the events surrounding it add to the reasons why some writers in fanfics might choose to show him in a negative light.
Well, it might be that the OC has a personal connection to an ongoing case. Hetty, being the shrewd character she is, hires the OC to use that connection to the team's advantage. Perhaps the OC has a past with a criminal organization that the NCIS LA team is currently investigating, and their inside knowledge could be crucial.
One great fanfic is 'The Unspoken Bond' which delves deep into their relationship during the early days at Hogwarts. It shows how they supported each other through tough times. Another is 'A Shared Legacy' that focuses on their cooperation in protecting Hogwarts. And 'In the Quiet Moments' which is more about their private conversations and the unsaid feelings between them.
