America can help in Harry Potter fanfiction by providing additional manpower. Imagine a situation where Voldemort's influence spreads globally. American wizards, with their own set of skills and abilities, could join forces with the British wizards. They might have different approaches to combat magic, like more emphasis on elemental magic which could be a new strategy against the dark wizards. Also, their magical creatures might be different, and some of them could be used to counter the threats in the story.
It's possible that an old acquaintance from Hogwarts who has family ties in America could assist him. This person might already have a network in America and could introduce Harry to important people. Also, there could be some reclusive magical scholars in America who, out of curiosity about Harry's powers and his role in the UK, decide to help him. They could teach him new magical skills that are specific to the American wizarding world.
One possible fanfiction could be about Harry Potter visiting America and encountering a new form of dark magic related to death. Maybe he goes to a haunted place in America, like an old plantation, and has to deal with a death - based curse.
In the world of Harry Potter fanfiction, Harry might need help in various ways. For example, he could need help dealing with a new dark wizard threat that the original books didn't cover. Maybe he's struggling with his post - war trauma and needs the support of his friends more than ever. Another possibility is that he's in a situation where he has to learn a new and difficult magic spell to save someone he loves, but he can't seem to master it on his own.
Harry might meet some American wizarding families that have long - standing traditions different from the pure - blood families in the UK. These families could introduce Harry to new forms of magic and social norms within the American wizarding community. He could also meet American Muggle - born wizards who have their own unique stories of discovering magic in a different cultural context compared to what he's used to.
In fanfiction, goblins can help in various ways. For example, they might assist Harry Potter with getting access to certain Gringotts vaults that hold crucial items or information. Goblins are known for their skill in handling gold and guarding treasures, so they could use their knowledge to help Harry in his fight against Voldemort by providing him with financial resources or magical artifacts that were previously hidden away.
Perhaps he's following a lead related to his parents. There could be some secrets about his family that are hidden in America. He goes there to uncover the truth and learn more about his family's past that might not be available in the UK.
A third concept could be that a magical object from the Harry Potter world, like the time - turner, is found in the Marvel universe. Captain America and the Avengers have to figure out how to use it. Meanwhile, Harry and his friends are searching for the time - turner in their world too. Eventually, their paths cross as they both try to understand the power of this object.
Sometimes, new original characters are created in fanfiction to help Harry. These could be students from other wizarding schools who have unique skills. For example, a student from a school in a far - off land who has mastered a type of magic that is unknown in Hogwarts and uses it to help Harry in his fight against the dark forces.
His friends from Hogwarts, like Ron and Hermione, are likely to help. Ron could bring his family's practical knowledge of wizarding homes and Hermione would contribute with her extensive research skills.
