Begin with brainstorming the significance of the Resh umbrella in your fanfiction. Is it a magical item? A technological wonder? Once you've determined that, think about the characters from different stories you want to bring together. Sketch out a basic plot where the umbrella acts as the catalyst for their meeting. For example, if you're doing a crossover between a post - apocalyptic world and a magical realm, the umbrella could be the key to opening a portal between the two desolate and fantastical places.
One idea could be to have characters from different universes meet under the Resh umbrella. For example, a character from a fantasy world and a character from a sci - fi world could find themselves taking shelter under the same Resh umbrella during a strange interdimensional storm.
Imagine that in the Resh umbrella world, there is a powerful weapon that could potentially destroy the entire multiverse if it falls into the wrong hands. The Avengers are somehow alerted to this threat. They cross over into the Resh umbrella world. There, they meet characters from Resh umbrella who have different motives. Some want to use the weapon for power, while others want to destroy it. The Avengers have to navigate this complex situation, make allies among the Resh umbrella characters, and ultimately prevent the weapon from being misused.
The characters from Resh umbrella might be initially in awe of the superpowers of the Avengers. For example, Iron Man's high - tech suit would be a wonder to them. Meanwhile, the Avengers might be a bit cautious of the Resh umbrella characters as they come from a more shadowy and secretive organization. But they would soon realize that they have to work together and start sharing their skills and knowledge.
Think about the characters' personalities and how they would react to the new situation. If you're crossing with 'Doctor Who', the time - traveling aspect could be a great source of conflict or adventure for the Umbrella Academy. The Doctor's vast knowledge and experience would contrast with the Umbrella Academy's more home - grown, dysfunctional knowledge. Start with a simple idea like the TARDIS landing in the middle of the Umbrella Academy's house and go from there.
To start writing a chara crossover fanfiction, you should start with brainstorming ideas for how the characters will interact. Will they be friends or foes at first? Also, think about how the different rules and worlds of the original characters will blend or clash. For example, if you're crossing a magical character with a non - magical one, how will that work? Sketch out a rough outline of the story, including the beginning, middle, and end. You can start with a simple premise like 'What if these two characters met?' and then build on it. Consider the character arcs for each of the crossed - over characters. How will they change during the story?
Begin by brainstorming ideas. Think about what would happen if the 'legion' met a different group of characters. You can draw inspiration from other crossover fanfictions you've read or movies/TV shows you've seen. After that, develop your characters. If you're bringing in characters from different universes, give them new dynamics. They might be initially suspicious of each other but then learn to work together. And don't forget to set the scene. Describe the new world that is created by this crossover, whether it's a mix of the 'legion' world and another or a completely new place where they all end up.
To start writing 'Battletech Crossover Fanfiction', begin by choosing a crossover that has potential for great stories. Say you pick 'Battletech' and 'Full Metal Panic'. Research both universes thoroughly. Next, create a strong plot. Maybe the mechs are being used in a war on a planet similar to the one in 'Full Metal Panic'. Develop your characters well, like how a Battletech pilot would react to the situations in the other universe.
Begin by exploring the personalities of Robin and the character he is crossing over with. If it's, say, Robin and Supergirl, understand how Robin's detective skills and combat training would interact with Supergirl's superpowers. You can start with a small encounter between them, like they meet by accident and then gradually build up to a bigger adventure. Also, don't forget to add some conflict, whether it's internal (Robin struggling with his own insecurities) or external (facing a powerful enemy).
Begin by creating a character profile for Android 21 in this new crossover setting. Consider her goals and how they might change. Also, establish the rules of the new world she's in. If it's a world of magic, how will her powers interact with magic? You can start with a simple scene, like her arrival in the new world, and build from there.
Begin by brainstorming interesting scenarios. If you're doing an 'It' crossover with a sci - fi story, think about how the otherworldly elements of 'It' like the sewers and Pennywise's powers would work in a sci - fi setting. Decide on your main characters from both universes. Then, create a rough plot outline. You could start with a character from one world stumbling into the other. It's all about being creative and having fun with it.
