In such a crossover fanfiction, the universes could blend through shared quests. For instance, a new evil force that is interested in both the power of the Juubi and the powers of the Greek gods. Naruto and Percy would be brought together to fight this common enemy. Along the way, Naruto would introduce things like chakra and ninja tools to Percy, while Percy would show Naruto things like the Camp Half - Blood and his sword Riptide. This way, their universes would gradually merge.
One way could be through the use of portals. Maybe there's a rift in the fabric of reality that connects the world of Percy Jackson to the realm where Slenderman exists. Demigods could accidentally stumble upon it and find themselves face - to - face with the horror. Another way could be a spell gone wrong. A magician in the Percy Jackson universe tries to do a powerful spell and instead of the intended result, it summons Slenderman.
In a crossover fanfiction, the settings could merge. For example, Camp Half - Blood could be visited by Naruto. The demigods would be intrigued by his chakra abilities, which are so different from their own powers based on the Greek gods. Naruto could teach them some of his ninja skills in return for learning about their combat techniques. And perhaps the Juubi's presence could disrupt the natural balance of the Percy Jackson world, leading to new and unexpected adventures for both Naruto and the demigods.
The plot could start with a strange rift opening between the Naruto universe and the Percy Jackson universe. Naruto, with the Juubi's power inside him, gets sucked into the Percy Jackson world. At first, there's a lot of confusion. The demigods are on guard, thinking Naruto is a new kind of threat. But as they start to communicate, they realize they have a common enemy in the form of a powerful being that wants to take advantage of the chaos caused by the rift. So, they team up to fight this enemy.
In some fanfictions, the settings are merged. So you might have Camp Half - Blood with a touch of Hamilton - era architecture or the characters from Hamilton having to deal with the monsters from Percy Jackson's world. The values of loyalty and friendship from Percy Jackson can also be contrasted with the power - hungry and ambitious nature of some Hamilton characters, creating really interesting storylines that are more than just the sum of their parts.
It could be a really exciting story. Imagine Naruto's ninja skills combined with the powers of the Juubi in the world of Percy Jackson. Naruto might use his Rasengan against some mythical monsters. And Percy could show Naruto the underwater world of the demigods. The two different mythologies and power systems would create a lot of interesting conflicts and friendships.
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.
Well, they often blend the two universes by having the characters meet. For example, Ruby could run into Percy and they start to explore each other's worlds. They might also blend the powers. Maybe Weiss could use her Glyphs while Percy uses his water powers in a combined attack against a common enemy.
It could blend the two worlds by having a common enemy. Let's say a powerful being that threatens both the ninja world and the world of Greek mythology. Percy and the Naruto characters would have to team up. The Mokuton abilities could be used in unique ways to fight this enemy. For instance, creating huge wooden barricades to hold off the enemy's attacks while Percy uses his powers to strike from a distance. The two worlds' cultures and powers would mix as they strategize together.
In these fanfictions, the different universes blend in various ways. The Juubi can act as a sort of catalyst. It might be that the Juubi's power is so great that it creates a portal between the Naruto and One Piece worlds. Once the characters start interacting, they share their knowledge and skills. The One Piece characters learn about ninjutsu and the Naruto characters learn about sailing and the different islands. In the harem aspect, the main character's journey through both worlds attracts different female characters from each, creating a diverse harem that represents both universes.
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.
