Maybe Harry discovers a hidden part of the wizarding world that uses guns as a form of magic - enhanced weaponry. So he has to learn how to use these guns in combination with his magic to defeat a powerful villain. For example, the guns could be enchanted to fire spells instead of normal bullets, and Harry has to master this new form of combat.
I'm not sure specifically which 'harry fights with guns fanfic' are out there. You could try searching on fanfiction websites like Archive of Our Own or FanFiction.net. Just type in the key phrase 'harry fights with guns' in their search bars and see what comes up.
First, do your research on both Guns and Roses and Harry Styles. Know their music styles, their personas, and their fan bases. Then, come up with an interesting concept, like a crossover concert or a song - writing session. Start with an engaging introduction that grabs the reader's attention.
A 'Harry Potter with Guns' fanfic would likely blend the muggle concept of guns with the magical elements of the Potterverse. It could introduce new characters who are experts in both gunsmithing and magic. These characters could teach Harry and his friends how to use guns in a magical way. For instance, they might enchant the bullets to have different magical effects like stunning spells or even the ability to break through powerful magical shields. It would be a unique crossover that could attract fans who like to see the familiar world of Harry Potter in a completely new and unexpected light.
One implication is that it changes the power dynamics. Guns can be a very powerful weapon in the Muggle world, and in a fanfic, it might make Harry seem more 'Muggle - like' in his approach to fighting. It could also lead to interesting interactions with other characters who are used to magic - only solutions.
Sure. Fanfic writers often come up with unique ideas. In some Guns and Roses and Harry Styles fanfics, they might imagine a scenario where the members of Guns and Roses meet Harry Styles at a music festival. They start sharing stories about their music - making experiences, and then Harry Styles ends up writing a song with them. It's all about the creativity of the writers and how they blend these two musical elements together.
A detective - themed fanfic might work too. Harry could be a detective in a gritty, crime - ridden city. He's cold because he has seen so much of the seedy underbelly of society. His use of guns comes in handy when dealing with dangerous criminals. He might be on a case that forces him to face his own demons as well as the external threats.
One common theme is the revelation of secrets. Often, Harry discovers something about Snape that makes him want to fight, like Snape's connection to the Dark Arts or some hidden actions he has taken against Harry or his friends.
Perhaps in this fanfic, Harry teams up with some of his Hogwarts friends. They combine their magical knowledge and courage. For example, Hermione could use her research skills to find a weakness of the Daleks, while Ron provides support and loyalty in the fight. And Harry, being the main hero, directly engages with the Daleks using his powerful spells like Expelliarmus but modified to have an effect on the Daleks' technology.
