If this were to happen in the fanfiction, the entire magical world would be affected. The Ministry of Magic might be suspicious of Harry's new accessory. They could try to confiscate the mask, thinking it was a dangerous or unregulated magical item. Harry would then have to fight not only Voldemort but also the Ministry if they try to take away the mask. And the mask could also have some sort of connection to the Dark Arts, which would further complicate things for Harry, but also open up new plot possibilities for the author of the fanfiction.
Well, if Harry Potter were to wear Revan's mask, it could potentially give him some new powers or a different appearance. Maybe the mask has some sort of magic that is not from the wizarding world he knows. It could also make him look really cool and intimidating to his enemies.
The prophecy about Harry and Voldemort would take on a new meaning. If Merlin was in Harry, he might see the prophecy as just another part of the cycle of good vs. evil that he has already experienced in Camelot. He would approach the battle with Voldemort with a different strategy, perhaps using his knowledge of ancient magic to find a more permanent solution to the dark wizard threat.
In the fanfiction, Darth Revan's training of Harry Potter would be a blend of two different training regimens. Revan would begin with mental training. He would teach Harry to clear his mind, much like a Jedi does, but with a Sith - like focus. This would help Harry control his magic more precisely. Next, he would focus on Harry's combat skills. He would show Harry how to use his wand more like a weapon, not just a tool for casting spells. For instance, using it to block physical attacks as well as magical ones. He would also introduce Harry to the concept of using the environment in combat, like using objects around him to enhance his spells or create distractions. And he would constantly push Harry to his limits, believing that only through extreme challenges can one truly grow in power.
The international relations of the wizarding world would be redrawn. Queen Elizabeth would use her diplomatic skills to strengthen ties with other wizarding countries. She might also introduce new trade policies. For example, trading magical artifacts for Muggle - made goods that could be useful in the wizarding world. The story could also explore how the wizarding world, under her rule, would interact with the Muggle world on a more regular basis. This could lead to some interesting plotlines, like how Muggles would react to the existence of a wizard - ruling queen and how the wizarding world would keep their secrets while still having a closer relationship with Muggles.
If Hermione were Snape's soulmate in fanfiction, it would drastically change the storyline. For one, Hermione's loyalty might shift from Harry and Ron. Her focus would be more on Snape, and she might be involved in his schemes and plans. This could lead to a different outcome in battles as she might influence Snape's decisions. Also, the relationship between Snape and the trio would be completely different. Instead of being a somewhat antagonist to Harry, Snape could be more of an ally through Hermione.
The storyline would change a great deal. Naruto's presence as a fishman would disrupt the existing power dynamics. His unique abilities would attract the attention of various factions in One Piece. For instance, the Marines might see him as a threat or an opportunity. And the Straw Hat Pirates might welcome him for his skills. His fishman nature would also give him access to areas and secrets that normal humans can't reach in the One Piece world.
The storyline would be a wild mix. Harry would likely grow up with a scientific and technological influence from Tony. This could lead to him inventing some magical - tech hybrids. His approach to the Triwizard Tournament might be more strategic in a tech - based way. And instead of just relying on magic, he could use Stark's resources to uncover secrets about his parents' death and Voldemort's plans. He might even have a suit like Iron Man's but with a magical twist.
In such fanfictions, the lack of parental support means Harry might form different relationships. For example, he could rely more on his friends or other adult figures like Sirius or Remus in a different way. The dynamic at Hogwarts could also change. Without the influence of his parents' love, he might be more vulnerable to the taunts of his classmates, which could lead to a darker path for his character. He could also be more desperate to prove himself, which might make him take more risks.
The storyline might involve Dark Naruto being a mystery to the Hogwarts students and teachers. At first, they might mistake his powers for some new and extremely dangerous form of dark magic. He could disrupt the balance in the wizarding world. For example, he might try to take control of the Forbidden Forest, using his ninja skills to outwit the magical creatures there. And his presence could force the wizarding community to re - evaluate their understanding of magic and threats.
The story could be about how Revan trains Harry to be a more strategic thinker. Harry, who has often been reactive in his battles against Voldemort, could learn from Revan's military tactics. Revan might teach him how to plan battles, how to analyze his enemies' weaknesses, and how to use his allies more effectively. This would make Harry a much more formidable opponent in the fight against the Dark Lord.
