Well, in fanfic, it could be a really interesting plot device. It might be used to create a new scenario where Harry Potter has to deal with the implications of having a federal identification in a magical world that usually operates under its own set of rules. Maybe it's used to bring the wizarding world more in line with the Muggle government systems for the sake of the story.
You could also have a plot where Harry discovers that his family has some hidden connection to a Muggle - wizarding cooperation project that requires federal identification. So, he's thrust into a situation where he has to understand this new part of his identity. He might face challenges from other wizards who oppose this new form of identification or from Muggles who don't believe a wizard should have such a thing.
In fanfic, 'harry potter has federal badge' could be a really interesting and unique concept. It might imply that Harry Potter is somehow involved with a federal - perhaps a wizarding federal - system. It could be a way to introduce new power dynamics or storylines where Harry has an official status or authority represented by the federal badge.
It could work by giving Harry new responsibilities. The badge might come with certain tasks he has to fulfill, like maintaining order in the wizarding world.
I'm not sure specifically as I haven't read this particular fanfic. But generally, it might involve Bella having a federal badge and getting into various adventures or situations related to that. Maybe she uses the authority that comes with the badge to solve mysteries or face challenges in a fictional world.
In the vast world of fanfiction, there are all kinds of concepts. 'Harry potter is a federal agent fanfiction' has the potential to be popular. The idea of Harry Potter, a well - known wizard, being a federal agent is a big departure from the original story. It gives fanfiction writers a chance to explore how Harry would adapt to a non - magical law enforcement role. His magical skills and knowledge could be translated in unique ways in this new setting, which might draw in readers who enjoy seeing familiar characters in new and unexpected situations.
A plotline could involve Harry being recruited by a special branch of the federal agency that deals with supernatural threats. He then has to work with non - magical agents to keep the world safe from dark magic - related crimes. He might have to teach his colleagues about the existence of magic while also adapting to their methods of investigation. There could be a lot of conflict and cooperation between the two groups as they try to solve cases together. Another aspect could be that Harry has to hide his identity as a wizard from the public while still using his powers for good in this new role.
Maybe there are corrupt officials within the same federal system who see Bella as a threat to their illegal operations. They would try to get rid of her or stop her from uncovering their misdeeds. These antagonists would use their own power and influence within the system to create obstacles for Bella.
Probably not. It has such a strange and unappealing - sounding name that it's likely not going to be mainstream popular. Most popular Harry Potter fanfics tend to stick to more recognizable themes within the wizarding world.
