How can I start writing a Detective Conan crossover fanfiction?

First, know the characters well. Read the manga and watch the anime to understand their personalities, relationships, and backstories. Then, come up with an original mystery or case. It could be something related to the existing storylines or a completely new concept. For example, a mystery involving a new villain in the Detective Conan universe.

First, decide who gets kidnapped. It could be Conan, Ran, or any other important character. Then, think about the motives of the kidnapper. Are they related to the main plot of the Detective Conan series, like the Black Organization, or is it a new, independent threat? After that, plan out how the kidnapped character will react. If it's Conan, he'll likely be calm and start looking for ways to escape or send signals. Outline the steps the other characters will take to rescue the kidnapped one. You can also add some twists, like false leads or unexpected allies.

First, you need to develop your OC. Decide on their appearance, personality, and skills. For example, if your OC is a detective, what makes them different from Conan? Then, think about the plot. It could be a new case that Conan and your OC work on together. Maybe start with a simple mystery, like a stolen item from a local store. Next, write an engaging opening. You can start with a description of the crime scene or an introduction to your OC. For instance, 'The sun was setting as [OC's name] walked down the busy street in Beika, not knowing that she was about to stumble upon a mystery that would change her life.'

First, think about the supernatural element you want to introduce. It could be magic, psychic powers, or something else. Then, figure out how it will interact with the existing Detective Conan world.

First, think about the relationship between Conan and the AI. Will they be friends or foes? Then, come up with a plot. It could be a mystery that only their combined skills can solve.

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.
