Authors create unique storylines by mixing the magic systems. For instance, if it's a crossover with 'Doctor Strange', they might combine the time - turning spells of Harry Potter with the time - manipulation abilities of Doctor Strange. They also play with character personalities. A shy character from one universe might befriend a bold character from the other. Another way is by creating new threats that require the combined efforts of both universes' heroes.
One important way is by exploring the cultural differences between the two universes involved in the crossover. If it's a crossover with a Japanese anime universe, the cultural values and norms of Japan could be contrasted with those in the wizarding world. This can lead to interesting character dynamics. Also, authors might bring in elements from mythology. In a crossover with Greek mythology, they could have the Greek gods interacting with Hogwarts professors. And they can create new hybrids of creatures from both universes, like a centaur - like being that has the powers of a character from another story. All these elements combined result in unique and captivating storylines.
One popular crossover is with the 'Lord of the Rings' universe. In these fanfics, characters might interact in various ways. For example, Frodo could meet Harry Potter and they could exchange stories about their quests against dark forces. Another is with the 'Star Wars' universe, where wizards and Jedi might have to collaborate. And then there's the crossover with the 'Percy Jackson' series. Demigods and wizards could find themselves in a situation where they need to combine their powers to face a common enemy.
Well, first of all, they really dig into the lore of both the Harry Potter world and the other world they are bringing in. Let's say it's a crossover with the His Dark Materials series. They would look at how Dust in His Dark Materials and magic in Harry Potter could interact. Then they play with the settings. If it's a crossover with Middle - earth, they might have Hogwarts in Middle - earth or vice versa. And for the characters, they might give them new relationships. For instance, if Ginny Weasley meets Lyra Belacqua, they could form an unexpected friendship or rivalry based on their different backgrounds and skills.
She could be more empathetic as a female. Maybe she uses her intuition more in her magical studies and battles. For example, instead of just charging into a fight like the male Harry, she might first assess the situation with her heightened emotional intelligence.
By combining the magic systems. For instance, Magnus' rune magic could be used in Hogwarts. A character could draw runes on their wands to enhance their spells. It's a simple yet effective way to create a unique crossover.
Authors create believable relationships by first understanding the personalities of the characters from both universes. For example, if it's a crossover with 'Lord of the Rings', they need to consider how a hobbit's simple and home - loving nature might interact with a Hogwarts student's more academic and magical - focused life. They also use shared experiences, like facing a common enemy together. This could bring two characters closer in a romantic way.
Authors often start by taking the existing relationships in the 'Harry Potter' series. They then twist the dialogue or actions to have a double meaning. For example, they might rewrite a scene where characters are sharing a meal at the Great Hall to include some flirtatious remarks with innuendo.
Authors create an 'evil Harry Potter' in fanfiction by changing his backstory. Maybe he has a different experience at Hogwarts, like being bullied by the teachers instead of being mentored. This can turn his character bitter and lead to him becoming evil.
The unique storylines also come from the fact that the two universes have different power systems. In Harry Potter, it's about magic power and knowledge. In Riddick, it's about physical strength, combat skills, and the ability to survive in harsh conditions. Fanfiction can explore how these power systems interact. Maybe a character from Riddick's world is given a magical item and has to figure out how to use it without any prior knowledge of magic, or a Harry Potter character has to rely on Riddick - style survival skills when their magic fails them.
Combining them could involve using the time - travel or alternate - reality concepts. Suppose there's a magical accident that links the world of 'Once upon a time' to the Harry Potter world. Characters might have to deal with different magical rules. For instance, the magic in 'Once upon a time' might be more fairy - tale based, like true love's kiss having great power, while in Harry Potter it's more about spells and potions. The characters would need to figure out how to use both types of magic to solve problems and save both their worlds from a common threat.
One idea could be a crossover with the world of Narnia. Harry and his friends could accidentally stumble into Narnia through a magical portal. They would then have to adapt to the new world, deal with the White Witch, and maybe use their own magic to help the Narnians. Another plot could involve a crossover with the Lord of the Rings. The Hogwarts students could be transported to Middle - earth to help in the fight against Sauron. They could use their unique spells and magical abilities in battles against orcs and other dark forces. A third idea might be a crossover with Alice in Wonderland. Harry could follow a strange magical creature down a rabbit hole and end up in Wonderland, where he has to solve the crazy riddles and deal with the mad characters while also trying to find his way back to Hogwarts.
