To write a great Meliodas crossover fanfiction, start by brainstorming unique concepts. For instance, you could put Meliodas in a post - apocalyptic world and see how he adapts. Develop his character further in this new setting. When it comes to the crossover element, make sure to blend the two universes' rules and lore. If it's a crossover with a magical girl anime world, for example, find a way to make Meliodas' power set fit in. Use vivid descriptions to bring the story to life and make the readers feel like they are in the world you've created. Write dialogues that are true to both Meliodas' character and the new world's inhabitants.
Often, they start off as strangers and then gradually become friends. They might be initially suspicious of each other's powers but then come to respect them.
Create an interesting plot. It could be a continuation of the existing story, a 'what - if' scenario, or a completely new adventure for Meliodas. For example, you could write about what would happen if he lost his powers for a while and how he would cope.
Next, think about the plot. It could be something related to the themes in the original work, like his quest for redemption or protecting his friends. But add your own twist, maybe a new villain or a different goal for him. Also, if it's adult - themed, make sure to handle it tastefully and with respect to the source material.
First, study their characters. Know Elizabeth's kind - hearted and strong - willed nature, and Meliodas' complex past and his charming yet mysterious personality. Then, think of a unique plot. It could be about a new adventure they go on together. Next, focus on their interactions. Write dialogue that shows their love and respect for each other. For example, Meliodas might say something flirty to Elizabeth and she could respond shyly. Also, describe their emotions well, like when they are separated or reunited.
Naruto's shadow clone jutsu could be used in really creative ways when combined with Meliodas' combat style. For example, the clones could surround an enemy while Meliodas attacks from the front, confusing the foe. Also, Naruto's rasengan could potentially be enhanced with Meliodas' demonic energy, creating a more powerful attack.
There could be some stress on their relationship too. The responsibilities of impending parenthood might cause some arguments. For instance, they might disagree on where to raise the child or how to handle the child's potential powers. But these conflicts would ultimately strengthen their bond as they work through them together, learning more about each other in the process.
If they were in a situation where they needed to combine their powers, Naruto's Sage Mode, which gives him enhanced strength, speed, and perception, could work well with Meliodas' Full Counter ability. Naruto could sense incoming attacks and Meliodas could then use Full Counter to send those attacks back with even greater force. Also, Naruto's Nine - Tails chakra could potentially merge with Meliodas' demon power in some way, creating a new and extremely powerful force. It could be like a combination of the raw power of the Nine - Tails and the unique abilities of Meliodas' demon form.
Diane would probably be overjoyed. She's always been close to Meliodas and Elizabeth, and she would likely offer to protect them and help out in any way she can. Maybe she'd use her giant strength to build a special place for them to stay during the pregnancy.
For Meliodas, remember his past and how it has shaped him. His experiences as a former leader of the Seven Deadly Sins should come through in his actions and decisions. Diane, on the other hand, her love for nature and her loyalty to her friends are key aspects. When writing a scene where they interact, show how Meliodas' quick thinking complements Diane's more methodical approach.
