First, decide which two (or more) universes you want to cross over. For example, if it's Godzilla and the Avengers, research both. Know the characteristics of Godzilla and the powers and personalities of the Avengers. Then, come up with a basic plot. Maybe Godzilla has been summoned to New York by an unknown force and the Avengers think he's a threat at first. Start writing an opening scene that grabs the reader's attention, like a sudden appearance of Godzilla in the middle of the city.
First, decide which other universe you want to cross over with. For example, if it's 'Narnia', study both the Harry Potter world and Narnia's lore. Then, think of a plot that would bring the two worlds together. It could be something like a magical portal opening between Hogwarts and Narnia. Next, create new characters or use existing ones from both universes. Don't be afraid to give them new personalities or abilities based on the crossover.
First, decide which other universe you want to cross RWBY with. It could be an anime, a movie, or a book series. Then, study the lore and characters of both RWBY and the chosen universe thoroughly. For example, if you choose to cross with Lord of the Rings, understand the different races, magic systems, and the overall story arc. Next, think of an interesting plot that can bring the two universes together. Maybe a portal opens between Remnant and Middle - earth. After that, start developing your characters. How would Yang react in the presence of orcs? Sketch out the story structure and start writing. Don't be afraid to be creative and put your own spin on things.
First, choose the two anime you want to cross over. Make sure you know the characters and storylines well. For example, if you pick 'Dragon Ball' and 'My Hero Academia', study how the power systems work in both. Then, come up with a basic plot idea, like the heroes from 'My Hero Academia' need Goku's help to defeat a super - powerful villain in their world.
Start by choosing a crossover concept that interests you, like a Shin Godzilla and Transformers crossover. Next, establish the rules of this new combined universe. Will Godzilla be able to damage the Transformers? How will the Autobots or Decepticons view Godzilla? Then, start writing the beginning of the story. You could start with a mysterious event that brings Godzilla into the Transformers' world, like a space - time rift. From there, develop the plot by showing how different characters respond to this new situation and how their goals might change.
Begin with research. Watch the Godzilla movies that feature Little Godzilla to get a feel for his behavior and abilities. Then, brainstorm ideas for a story. Maybe start with a simple 'what if' scenario, like 'What if Little Godzilla found a magic crystal that gave him new powers?' From there, build your plot, characters, and conflicts.
First, think about the type of transformation you want. Is it a physical change in Godzilla's appearance? Or something more related to its powers? Then, create a setting. Maybe it's modern - day Tokyo or a post - apocalyptic world. Just start with a simple idea and build on it.
First, you need to be really familiar with both the World of Warcraft lore and the other source you want to crossover with. For example, if it's a crossover with 'Game of Thrones', know the politics and characters of both worlds. Then, come up with a basic idea like what if a WoW hero gets involved in the power struggles of Westeros? After that, start building your characters, thinking about how their personalities will change or adapt in this new crossover situation.
First, you need to choose the cartoons you want to cross over. Think about which ones have interesting characters and worlds that could blend well. For example, if you choose 'Adventure Time' and 'Steven Universe', consider how Finn and Jake would interact with Steven and the Crystal Gems. Then, come up with a basic plot. It could be a simple adventure like they all have to find a lost magical item. After that, start writing the introduction, introducing the characters from both cartoons in an interesting way.
Begin by choosing the crossovers carefully for your 'ben 10 crossovers fanfiction'. Let's say you want to cross it with Avatar: The Last Airbender. You should understand the powers and cultures in both. For Ben 10, it's the aliens and for Avatar, it's the bending. Next, create a conflict. Maybe an alien from Ben's world is causing problems in the Avatar world that only a combination of bending and alien powers can solve. Start with a simple outline of the story, including the beginning, middle, and end. Then start filling in the details as you write, don't worry too much about making it perfect at first.
To start writing 'Overwatch crossovers fanfiction', you need to be very familiar with both the Overwatch world and the other universe you're crossing it with. Do a lot of research on their settings, characters, and storylines. Then, create a scenario where the two worlds collide. Maybe start with a character from Overwatch accidentally ending up in the other world. You can then build the story around their attempts to get back home while interacting with the new characters and facing new challenges.
