Well, a great crossover idea is when Harry Potter and his friends seek Sherlock Holmes' help to figure out the true identity of Voldemort before he fully returns. Sherlock could analyze the dark wizard's past actions and the prophecies in a very different, logical way compared to the wizarding world's methods.
In some fanfictions, Harry Potter could visit 221B Baker Street. There, he might learn from Sherlock about how to observe people more closely, which could help him in his battles against the Dark Arts. Also, Watson could befriend Harry and teach him some basic first - aid skills, which could be useful in the wizarding world where dueling often leads to injuries.
One interesting story could be where Sherlock Holmes is called upon to solve a mystery within the wizarding world of Harry Potter. Maybe a series of strange disappearances at Hogwarts that even the professors can't figure out. Holmes' deductive reasoning skills would be put to the test in a world filled with magic.
One interesting story could be about Harry Potter using his magic skills to assist Sherlock Holmes in solving a mystery that involves dark magic in London. It might show how their different worlds of magic and deduction collide and complement each other.
Another theme is the power of intellect. Both Harry Potter (even in the fem version) and Sherlock Holmes are highly intelligent in their own ways. Fanfictions usually play on how their combined intelligence can solve complex problems that neither could solve alone. For example, in many stories, they might be trying to solve a mystery that involves both magic and non - magic elements. The female Harry Potter can use her knowledge of magic and Holmes his deductive skills to get to the bottom of things.
Yes. In some ways, we can see elements that might suggest a connection. For example, both series are set in a world full of mystery. Harry Potter has the mystery of the wizarding world, the secrets of Hogwarts, and the enigma of Voldemort. Similarly, Sherlock Holmes is all about solving mysteries in the Muggle world. However, they are two very distinct universes with their own unique rules and characters, but the love for mystery might be a common thread that could make one think of Harry Potter as somewhat of a Sherlock Holmes - inspired fanfiction on a very loose level.
Well, in Harry Potter fanfiction, business can take many forms. There could be stories about the trade of magical artifacts on the black market. As for Sherlock Holmes fanfiction, he often deals with cases that may have a financial aspect to them, like fraud in a business deal. When it comes to combining the two in fanfiction, perhaps Sherlock could be called upon to solve a mystery in the wizarding business world, say a series of disappearances among the goblin bankers who handle the wizarding currency.
Harry Potter and Sherlock Holmes themselves. Harry has his unique insights into the wizarding world and the fight against dark magic, while Sherlock has his brilliant mind for solving complex cases. Together, they could face threats like Death Eaters and also solve magical mysteries that stump the wizarding community.
One interesting crossover could be the use of Avatar's bending abilities in the wizarding world of Harry Potter. For example, a character who can bend water could use it to create unique defenses against dark magic spells that involve fire. Another could be the idea of Hogwarts having an exchange program with the Avatar world, and students from each side learning about the other's culture and magic systems.
One interesting crossover could be the use of magic spells from Harry Potter in the Skyrim world. For example, the 'Expelliarmus' spell might be used to disarm an enemy in Skyrim instead of the normal combat disarming moves. Another could be the appearance of Hogwarts-like structures in Skyrim. Wizards from Harry Potter might also find their way into Skyrim and interact with the local mages there.
A really cool concept in this type of fanfiction is when the magic items from both universes interact. Like, what if the Philosopher's Stone was brought to Narnia? How would it affect the balance of magic in Narnia? And how would the Narnians react to such a powerful and mysterious object?
