One way writers merge the two universes is through character relationships. A fem Percy Jackson could form a friendship with Hermione. Hermione's thirst for knowledge could lead her to be intrigued by Percy's different kind of power and knowledge of the Greek gods. And Percy could learn a lot from Hermione about magic. Also, in terms of the plot, a common enemy could be created. Maybe a dark wizard is trying to harness the power of the Greek gods, and Percy and Harry have to team up to stop it. This forces the two universes to interact on a deeper level.
Writers often start by establishing how a fem Percy Jackson could end up in the Harry Potter universe. Maybe through a magical portal or some kind of cross - dimensional spell. Then they find ways to make her demigod powers interact with magic. For example, her ability to control water might have an unexpected effect on a magical water - based spell in Hogwarts.
In many fanfictions, magic is the key to merging the two universes. Fem Harry Potter's world of magic can act as a bridge. For example, a powerful spell might accidentally open a portal between the wizarding world and Metropolis, allowing the two to interact.
Some fanfictions merge the universes by having a shared event. Like in 'The Great Crossover Event', there is an event that draws characters from both the Harry Potter universe and the Yu - Gi - Oh universe together. Fem Harry Potter uses her magical skills, and she has to learn about the dueling system in Yu - Gi - Oh to participate. It's all about how these two different types of magic and combat styles interact with each other.
Another way is when a character from one universe is sent to the other on a quest. Let's say Percy Jackson is sent to the Naruto world to retrieve an object that has somehow ended up there. His presence then starts to mix the two universes as he befriends the ninjas and they learn about his world.
Well, in many fanfics, they merge the universes by having some sort of magical or scientific accident. For example, in one fanfic, a portal opened up between Camp Half - Blood and the Young Justice headquarters. The female Percy Jackson then gets sucked into the Young Justice world and has to adapt.
Well, in fanfiction, it could also be that there is a common enemy. For example, a powerful ancient being that is a threat to both the demigod world of Percy Jackson and the world that Agents of Shield operates in. This would force them to team up. Percy's powers like controlling water could be really useful in some of the situations that Agents of Shield faces, like dealing with underwater threats or putting out fires in a unique way.
Some fanfics blend the universes by having the characters meet. For example, they might create a situation where Percy accidentally ends up at Hogwarts or Harry somehow gets to Camp Half - Blood. This allows for a direct interaction between the two different sets of characters and magic systems.
Many fanfictions blend the two universes through the use of magic systems. They might combine the spells from Harry Potter with the powers of the demigods in Percy Jackson. For instance, a character might use a Patronus charm while also having the ability to control water like Percy. It also often involves creating new villains or threats that require the combined skills of both sets of characters to defeat. This makes for exciting and unique storylines.
In these fanfictions, they often blend the two universes by having the fem Harry Potter use her magic in the Legend of Zelda world. For example, her spells can be used in combat or to solve puzzles, just like Link uses his items. The magical creatures from Harry Potter might also appear in Hyrule, like hippogriffs or house - elves, which adds a unique twist to the Zelda setting.
One way they could merge is through a magical portal. Imagine if the demigods from Percy Jackson's world accidentally stumble upon a portal that leads them to Westeros. They might bring their unique powers, like Percy's control over water, and it would disrupt the power balance in Game of Thrones. For example, they could help in battles against the White Walkers, using their god - given abilities. This would change the whole course of the Game of Thrones story.
The two universes blend in various ways. In fanfiction, Percy's powers can be adapted to the Skyrim setting. His ability to control water can be used in Skyrim's many waterways. Also, the mythology of Percy Jackson can be merged with Skyrim's lore. For example, the gods in Percy's world could be compared or even interact with Skyrim's divines.
