Start with an engaging opening. It could be a scene of chaos as the two universes collide. Then, introduce the characters gradually. As you write, keep in mind the different personalities and how they would interact. Don't be afraid to deviate from the original storylines a bit to create something fresh, but also stay true to the essence of the characters from both the Sanctuary and the other crossover universe.
First, you need to be familiar with both universes of the crossover. For a 'sanctuary crossover fanfiction', know the characters, settings, and rules of the Sanctuary world and the other world you're crossing it with.
Begin by deciding on a central plot. Let's say you're doing a crossover of 'Aang' from 'Avatar: The Last Airbender' and 'CatDog'. Maybe there's a strange spirit that has the power to split CatDog apart, and Aang has to use his airbending skills to put them back together. You also need to get the voices of the characters right. Read up on how they talk in their original shows. And don't forget to set the scene, whether it's in the world of 'Avatar' or the wacky world of CatDog.
Begin by choosing the HP crossover concept. If it's an HP and 'Game of Thrones' crossover, consider the political intrigue in both worlds. In HP, there's the politics within the Ministry of Magic, and in 'Game of Thrones', there are the power struggles for the Iron Throne. Think about how the characters from both will interact. Maybe Dumbledore could be like a wise maester in the 'Game of Thrones' world. Once you have these ideas in place, start writing the opening scene. It could be a dramatic event that brings the two worlds together, like a dragon from 'Game of Thrones' showing up at Hogwarts.
First, choose the two or more source materials for your crossover. For example, if you like an anime and a video game, pick those. Then, think about the main character. Decide who will be at the center of this harem. After that, create a basic plot. Maybe it's about the main character getting lost in a new world that combines elements of the different source materials and meeting the various harem members there. Just start writing down your ideas and don't worry too much about making it perfect at first.
Begin by brainstorming the main characters from different franchises you want to include. Consider their personalities, powers, and relationships in their original stories. Next, determine the setting for your crossover. Will it be mostly in one universe with elements of the others, or a completely new world created by the crossover? Then, outline the conflict. It could be a character - driven conflict, like different values clashing, or an external threat that forces the characters to interact. For example, if you're crossing over superheroes and fantasy characters, a powerful magical - technological hybrid villain could be the threat. Also, don't forget to do some research on the different universes to make sure you're staying true to their core elements as much as possible while still creating something new.
First, you need to pick the fictional universes you want to cross over. Then, study the characters, settings, and rules of those universes. After that, think of a central plot that can bring the different elements together. For example, if you choose 'Pokemon' and 'Digimon', you could create a plot where a strange digital - pokemon hybrid virus is spreading and both trainers from each world have to work together to stop it.
First, choose the two (or more) fandoms you want to cross over. For example, if you like 'Sherlock' and 'Lord of the Rings', decide which elements of each you want to include. Then, think about a central plot. Maybe Sherlock is called to solve a mystery in Middle - earth. After that, start creating your characters' interactions. How would Sherlock react to meeting Gandalf? Just start writing down your ideas and build from there.
To start writing 'gamer crossover fanfiction', begin by researching the lore and characters of both games. If you're crossing over 'Super Mario' and 'Sonic the Hedgehog', know their personalities, abilities, and the worlds they come from. After that, come up with a conflict that would bring these two worlds together, such as a new villain who wants to take over both the Mushroom Kingdom and Sonic's world. You can also consider how the different power - ups and items from each game can be used in the crossover.
First, you need to be really familiar with the two manhwas you want to cross over. Know the characters, their personalities, powers, and the worlds they live in. For example, if you're crossing over 'Bleach' and 'Naruto' (assuming they count as manhwa for the sake of explanation), understand Ichigo's zanpakuto powers and Naruto's chakra - based abilities. Then, come up with a unique plot. Maybe a portal opens between the two worlds and characters start to interact. It could be something like the Soul Society in 'Bleach' discovers the ninja villages in 'Naruto' and there's a misunderstanding that leads to conflict, which the characters have to resolve.
First, you need to be familiar with both the Andromeda universe and the other universe you want to cross it with. Know their characters, settings, and rules. For example, if it's a crossover with Star Wars, understand the Force in Star Wars and the biotics in Andromeda. Then, come up with an interesting concept for the crossover. It could be a simple encounter between a character from each universe or a more complex plot like a shared threat. Next, start with an engaging opening. Maybe a mysterious event that draws the two universes together.
To start an AOT crossover fanfiction, think about the characters from both worlds. Consider how they would interact. If it's an AOT and a fantasy world crossover, like with Middle - earth from Lord of the Rings, think about how the AOT characters would react to the elves and dwarves. You can start by creating a scenario that brings the two worlds together, such as a magical portal opening between them. Then, begin writing the first scene, which could be from the perspective of an AOT character who is suddenly thrust into this new and strange world.
