Well, Harry Potter for sure. Then there could be Luna Lovegood, with her out - of - the - box thinking which could be useful in the unfamiliar territory of NY. And perhaps an older wizard who has been living in NY in hiding for years, who comes out of hiding to help Harry. This wizard could have a deep understanding of the city's magical underbelly and guide Harry and his friends through the battle.
Perhaps in this fanfiction, the Battle of NY is a result of a magical artifact being discovered in NY that has the power to change the balance of the wizarding world. Harry and his friends, along with some American wizards they meet, have to race against time to keep it out of the hands of Voldemort or other dark forces. They face challenges not only from the bad guys but also from the muggle authorities who are starting to suspect something strange is going on.
Luna Lovegood could be a main focus. Her unique perspective on magic could be used to discover new magical phenomena that emerged after the battle. She might also be helping the other students deal with their post - battle stress, using her calm and dreamy nature to soothe them.
For a Harry Potter battle school fanfic, the main characters could include some of the more under - rated students at Hogwarts. For example, Seamus Finnigan, who has shown his magical abilities in the past but could really shine in a battle school setting. Ginny Weasley, being a strong - willed and talented witch, could be a main character as well. Additionally, Draco Malfoy could be a complex main character, as he could either be a rival in the battle school or, over time, learn to work with the others against a common enemy.
Obviously, Harry Potter himself would be a main character. He could bring his skills and courage from the wizarding world to the Battle of Helm's Deep. Hermione Granger would also be there. Her vast knowledge of magic could be crucial in finding solutions during the battle. Ron Weasley too, with his loyalty and his own brand of wizarding skills. Maybe Hagrid could also be involved, his huge size and strength being an asset in the physical combat at Helm's Deep.
An older wizard who has been in hiding for years, perhaps because of a powerful enemy. He is a battle mage and his skills are well - known in the wizarding underground. When a new threat emerges in the wizarding world that endangers Hogwarts and the students, he comes out of hiding to train the young wizards in the ways of battle magic. He could bring a lot of old - fashioned magic and wisdom to the story, as well as some mystery as the characters try to figure out his past and why he was in hiding in the first place.
Obviously, Harry Potter himself. He would be a central figure as he was the key in the battle against Voldemort. His friends Ron and Hermione would also be important. They've been with him through thick and thin. Neville Longbottom would be another likely main character. His heroics in the final battle would give him a significant role in the post - battle world. Ginny Weasley too, as Harry's girlfriend and a brave witch in her own right.
Obviously, Harry Potter himself would be one of the main characters. His friends like Hermione Granger and Ron Weasley might also be involved. There could also be American wizards or witches that are central to the story, perhaps a young and brave New York wizard who teams up with Harry.
Neville Longbottom could be a main character. He has always had the potential for great things and in a world without Harry, he would be likely to step into the spotlight. He has the courage and the connection to Hogwarts that could make him a central figure in the fight against evil.
Hermione could also play a role. Given her intelligence and love for learning, she might take an interest in accounting to better manage the finances of the various causes she's involved in, like the Society for the Promotion of Elfish Welfare. So she could be a main character or at least a supporting one in this fanfiction.
Obviously, Harry Potter himself could be a main character. He could be the one who is initially reluctant to participate in a dance event but then discovers a new passion for it. Hermione could also be a main character as she might be the one researching the history and significance of different wizarding dances.
