Yes, there are likely to be such fanfictions out there. The Harry Potter and Pokemon universes are both extremely popular, and fans often like to combine different fictional worlds in fanfiction. You can try searching on fanfiction websites like Archive of Our Own or FanFiction.net.
As I mentioned before, Archive of Our Own (AO3) and FanFiction.net are good places to start. Just use the search bar on those sites and type in relevant keywords like 'Harry Potter', 'legendary Pokemon', and 'fanfiction'. There may also be some smaller, more specialized fanfiction communities that might have such stories, but those two are the most well - known and likely to have a wide selection.
One challenge is keeping the integrity of both universes. For instance, the magic in Harry Potter is very different from the powers of Pokemon. So, it's difficult to make sure that when they interact, it doesn't seem forced. Another challenge is the different fan bases. Some die - hard Harry Potter fans might not like the idea of mixing it with Pokemon, and vice versa.
Yes, it might be popular. There are many fans who enjoy crossovers like this. Harry Potter has a huge fan base and so does Pokemon. Combining the two universes, especially with a female version of Harry Potter, can attract a lot of attention as it offers a fresh take on both beloved franchises.
I think it is. Fanfictions often take existing universes and mix them up in new ways. Harry Potter has its own set of rules regarding magic and the wizarding world, while Pokemon has its own system of catching and evolving creatures. Combining these two means creating a whole new set of adventures. For example, imagine Harry and his friends going on a quest to find a rare and powerful Pokemon in the Forbidden Forest. It could lead to all kinds of new storylines that we haven't seen before.
The plot could be really diverse. For example, it could start with the fem Harry Potter accidentally ending up in the Pokemon world. She then discovers that there are some similarities between the two worlds, like the different types of Pokemon could be related to the different elements in the wizarding world. She might try to find a way back home while also getting involved in local Pokemon - related problems. There could be rivalries with other trainers, and she might have to prove herself not just as a wizard but also as a Pokemon trainer. Also, the fanfiction could explore her relationships with the Pokemon she meets, and how they interact with her magic.
Yes, there are many. In some fanfictions, the sword might have the power to cut through any dark magic. For example, it could be able to destroy Horcruxes more easily than in the original story. It might also have the ability to protect the wielder from the most powerful curses.
The legendary wands in Harry Potter are full of mystery. In fanfiction, a story could be about a wandmaker who tries to recreate the Elder Wand. He might study all the old texts and legends, but in the process, he discovers a dark secret about the wand - making process that was long forgotten. This could lead to a battle between good and evil, with the fate of the wizarding world at stake.
He would probably have a very unique team. For example, he could have a Ninetales because of its magical and fox - like appearance, which might remind him of his Patronus. His training methods would likely be a mix of wizardry and traditional Pokemon training. He might use spells to heal his Pokemon or to enhance their abilities in battles.
