First, decide which two (or more) universes you want to cross over. For example, if it's 'Back to the Future' and 'The Terminator', think about how the time - travel concepts in both will interact. Then, create a character - driven plot. Maybe the Terminator is sent back in time to Hill Valley to stop Marty from changing the future, but Marty has the DeLorean to outwit him.
You should start by researching the two universes thoroughly. If you're doing a 'Back to the Future' and 'Ghostbusters' crossover, learn about the rules of time travel in 'Back to the Future' and the technology and mythology of 'Ghostbusters'. After that, come up with a unique situation. For instance, the Ghostbusters could be called to Hill Valley because some time - travel - related ghosts are causing chaos, and Marty has to help them using the DeLorean.
Begin with a strong hook. In a 'Back to the Future' and 'Superman' crossover fanfiction, you could start with Superman seeing the DeLorean traveling through time and being intrigued. Then, you need to establish the relationship between the characters. Maybe Superman and Marty become friends and use their combined powers (Superman's abilities and the DeLorean's time - travel) to save both Metropolis and Hill Valley from a common threat that spans across different timelines.
First, decide on the main plot or idea. It could be something like a new time - travel adventure that wasn't shown in the movie. Then, think about the characters you want to focus on. Are you going to use the main characters like Marty and Doc Brown, or introduce new ones? After that, create an outline of the story, including the beginning, middle, and end. For example, start with a problem or a situation that requires time - travel to solve. In the middle, have the characters face various challenges during their time - traveling. And at the end, resolve the problem and show the consequences of their actions.
To start writing 'Back to the Future' fan fiction, begin by deciding which aspect of the franchise you want to focus on. Are you more interested in the time - traveling mechanics, the relationships between the characters, or exploring a new time period? After that, do some research on the 1950s, 1980s, and any other time periods relevant to the story. You can also create a character outline for the main characters, including their goals, fears, and quirks. For the actual writing, start with a simple plot idea, like Marty has to go back in time to correct a mistake he made during his previous time - travel adventures. Then, start writing the story, making sure to keep the tone and style similar to the movies.
You should start by establishing the setting. If it's a crossover with the Naruto universe, you need to figure out how Future Trunks gets to the Ninja world. Is it through a portal? Or some kind of magic spell gone wrong? Then, introduce the characters from both universes. Let them have initial reactions to each other, like Trunks being amazed at the ninjas' jutsu and the ninjas being in awe of his super strength.
Begin with researching the Glee universe. Watch the show again if you need to, to get a feel for the characters' personalities and relationships. Then, brainstorm some unique scenarios for their future. It could be something as simple as them getting back together for a holiday or as complex as starting a new musical movement in their town. Write down your ideas and start fleshing out the story from there.
First, decide on your main concept. It could be a new plotline, a character change, or a different setting. For example, if you want to change the character of Yuno, think about how this will affect the overall story. Then, create an outline. Outline the beginning, middle, and end of your fanfiction. This helps you stay organized. After that, start writing the first draft. Don't worry too much about grammar or spelling at this point.
To start a Kakuzu crossover fanfiction, you need to have a clear goal for the story. If it's a crossover with the DC universe, you could start with Kakuzu arriving in Gotham City. He might start causing chaos as he tries to amass wealth in this new, unfamiliar place. Think about how the existing characters in the DC universe, like Batman, would react to him. Build on these interactions, adding in elements of Kakuzu's backstory and motives to create a complex and engaging narrative.
First, you need to have a good understanding of the Asura lore. Know their culture, powers, and how they interact in their own universe. Then, choose the other universe you want to crossover with. Research that universe thoroughly as well. After that, think of an interesting plot point that could bring these two universes together. For example, a mysterious portal that connects the Asura world to the other.
First, decide which universe or character you want to cross Beerus with. This is crucial as it sets the tone and direction of your story. For example, if it's a crossover with the Naruto universe, think about how Beerus' powers would interact with ninjutsu. Then, create an interesting starting point. It could be Beerus accidentally landing in the Naruto world due to some sort of space - time rift.
You should also plan out the plot. Decide on a central conflict. It could be something like a common enemy that both sets of characters have to face. Maybe in a crossover with 'Zootopia', there's a villain who wants to disrupt both the human - like world of the descendants and the animal - centered Zootopia. Then, start writing an engaging introduction that hooks the reader right away.
Think about the themes you want to explore. In an Ultraman and Sailor Moon crossover, you might explore themes of heroism and friendship. You can start by writing a scene that shows the contrast between Ultraman's more serious, alien - fighting nature and Sailor Moon's more magical, girl - power approach. This contrast can drive the story forward and create interesting interactions between the characters.
