Well, it could be really cool. Yamato is a powerful weapon. Harry Potter is already powerful with his magic, but adding Yamato to the mix would make him almost unstoppable. He could use the sword's abilities along with his spells to defeat enemies in a very unique way. Maybe he could use magic to enhance the sword's power even further.
Well, if Harry Potter wields Excalibur in fanfiction, it would be a wild combination. Harry is already a powerful wizard, but Excalibur is a sword of legend. It might change the whole dynamic of the wizarding world. For example, the sword could cut through dark magic in a way his wand can't. Maybe it would attract the attention of other magical creatures who respect the sword's power. And it could also create some interesting relationships with Arthurian legends within the Harry Potter universe.
Well, if Harry Potter wields Mjolnir in fanfiction, it would be an absolute power explosion. Harry already has his magic skills from the wizarding world, and adding the power of Mjolnir would make him nearly invincible. He could use the hammer's lightning - based powers along with his spells, creating some really unique and powerful combat combinations. It would also change the dynamic of his relationships. His friends might be in awe, and his enemies would be even more terrified.
The story would be different as Harry would have a new weapon. His combat approach would change. Instead of relying solely on spells, he could use Yamato for close - range combat. This would add a new layer of action to the story.
Well, Naruto might gain new and powerful abilities. The dragon blade could potentially enhance his combat skills, allowing him to face stronger enemies. He could use it in combination with his existing jutsu, like the Rasengan. Maybe it gives him the power to control elements in a different way or even fly. It would surely change the power dynamics in the Naruto universe.
He might also be a bit confused at times. Some fanfictions deviate a lot from the real events in his life. For example, if there's a fanfiction where he has a completely different upbringing, it would be strange for him to read about. He could also feel a sense of flattery that so many people are interested in his story and want to create their own versions of it.
One common theme is the clash and融合 of different cultures. The magical British culture from Harry Potter and the Yamato culture come together. Another could be the idea of new friendships formed across these two different worlds.
In a 'Harry Potter in Gotham' fanfiction, Harry might team up with some of Gotham's heroes. For example, he could share his knowledge of magic with Batman. Harry's magical creatures knowledge could also come in handy. He might introduce Thestrals to Gotham as a new form of transport for the heroes during emergencies. Also, his ability to communicate with snakes could potentially help in dealing with some of the more reptilian - like villains in Gotham.
The idea of Harry Potter with a gun is quite interesting. One possibility is that he gets the gun from the muggle world accidentally. He might initially be confused about how to use it but then realizes its potential. This could lead to new alliances in the wizarding world. Some wizards might be intrigued by this new weapon and want to learn more about muggle technology, while others might be afraid and try to confiscate the gun from Harry.
It would be really strange. He might be very confused as fanfiction often contains different interpretations and sometimes wild ideas that are far from his own experiences. He might think it was some kind of strange magic that created these alternate stories about him and his friends.
Well, he could bring his magic skills to the team. Maybe he'd use spells like 'Expelliarmus' to disarm villains before the Avengers could even react. His ability to apparate could also be useful for quick getaways or surprise attacks on enemies.
