First, you need to research about Yu - Gi - Oh Zexal and the character of Dark Mist. Know their traits, abilities, and the world they exist in. Then, come up with an interesting plot. For example, you could have a story where a new character is possessed by Dark Mist and the heroes have to save them. Keep the dueling rules in mind if you include duels in your fanfiction.
To write a Yu - Gi - Oh Zexal Dark Mist fanfiction, start by creating a unique setting. Maybe it's a parallel universe where Dark Mist has more power. Develop your characters well, especially if you introduce new ones. You can also play with the existing relationships in Zexal. For instance, if you want to write about a character's struggle against Dark Mist, show their internal conflict and how they grow throughout the story. And don't forget to proofread your work to avoid grammar and spelling mistakes.
One possible fanfiction could be about Yuma and Dark Mist forming an unexpected alliance. Maybe Dark Mist has some hidden motives that initially seem malicious but as the story progresses, it turns out he's actually trying to protect Yuma from a greater evil in the Zexal world.
One good fanfiction could be 'The Encounter with Dark Mist in Yu - Gi - Oh Zexal'. It might explore a new duel where the protagonist has an unexpected encounter with Dark Mist and has to use unique strategies. Another could be 'Dark Mist's Origins in Zexal' which delves into the backstory of Dark Mist within the Zexal universe.
First, understand the characters from both series well. Know Naruto's determination and his growth throughout the series, as well as Yuma's courage in Yu - Gi - Oh Zexal. Then, create a unique plot that combines elements from both universes in a logical way. For example, you could have a tournament where both ninja skills and dueling skills are required to win.
A plot could be where Dark Mist has a premonition about a future danger to Yuma. He tries to warn Yuma, but Yuma is initially skeptical. As events unfold, Yuma realizes that Dark Mist was right all along and they must team up to prevent the disaster. This could involve battles against new and powerful foes.
First, focus on their unique relationship. Astral is an otherworldly being and Yuma is a passionate duelist. Show how they learn from each other. For example, Yuma can teach Astral about human emotions, while Astral can teach Yuma advanced dueling strategies. Second, create exciting duels. Describe the cards in detail, the strategies used, and the tense moments during the duel. Third, introduce new elements like a mysterious new card set or a hidden dueling technique.
First, you need to understand the characters well. Know their personalities, backstories, and powers from the original Yu - Gi - Oh Zexal series. This will help you create believable relationships. For example, if you're writing about a Barian who is usually seen as cold, you need to find a way to make their falling in love seem natural.
Another concept is a fusion of their powers. Suppose a villain creates a device that combines the power of the tailed beasts from Naruto and the Numbers from Yu - Gi - Oh Zexal. The heroes from both universes have to work together to stop this new threat. Yuma could use his ability to communicate with his monsters and Naruto could use his Sage Mode to sense the new evil power.
Yuma Tsukumo is definitely a popular choice. He's the main character, so there's a lot of material to work with. His growth as a duelist and his relationship with Astral are rich areas to explore. Another popular character is Shark. His complex backstory and his evolution from a rival to an ally are really interesting to write about. And then there's Kotori, as she provides a different perspective in the dueling world being a supporter of Yuma and having her own story arcs related to the group's adventures.
One possible fanfiction could be about the Female Barian Emperor's backstory. Maybe she wasn't always a part of the Barian forces. She could have been a normal being from a different dimension who was corrupted by the Barian power. In the fanfiction, she might struggle with her new - found dark nature while also having some remnants of her former self.
Another fanfiction could explore the backstory of a Barian female. How did she come to be in the Barian world? What were her experiences growing up there? This could involve her relationships with other Barians, her training, and how she developed her skills. It could also show how she first heard about the Yu - Gi - Oh Zexal world and what her initial thoughts were.
