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.
Well, in some fanfictions, their kiss might be a more impulsive act. For example, Yuma could be trying to prove a point to someone else, like a rival who doubts his feelings for Tori. So, he just goes for it and kisses her right there, which then leads to a whole new set of emotions and relationship developments for them both.
One possible fanfiction could involve Yuma being kidnapped by an unknown group who are after his powerful Xyz Monsters. They might hold him captive in an abandoned warehouse and try to force him to give up his deck. But Yuma, being the brave duelist he is, uses his wits and the bond with his Astral to find a way to escape and turn the tables on his captors.
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.
One possible fanfiction could be about an Arclight family member getting involved with a vampire in the Yu - Gi - Oh Zexal universe. Maybe a young Arclight discovers a hidden vampire clan and has to either fight them or make an alliance. It could be a story full of mystery and action, with card duels taking on new twists as vampire - related cards come into play.
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.
A common theme is self - discovery. The OCs often start as unknowns in the Zexal world and through their dueling experiences, they learn more about themselves. Another theme is friendship. They form bonds with the existing characters like Yuma and his friends.
Another theme is friendship. When characters from different series meet, they usually form new friendships or strengthen existing ones. This is often shown through them working together in duels or facing challenges as a team. In a lot of these fanfictions, you'll see Zexal characters and characters from other Yu - Gi - Oh shows bonding over their shared love for dueling.
One possible plot could be that Naruto somehow gets transported to the Yu - Gi - Oh Zexal world. He might meet Yuma and his friends. Since Naruto is a ninja with unique skills like shadow clones, he could help Yuma in his duels. For example, Naruto could use his clones to distract opponents while Yuma figures out his strategy. Maybe they team up to face a common enemy who is causing chaos in both the ninja world and the Zexal world.
The Yu-Gi-Oh! Zexal manga and anime have their distinctions. Sometimes, the anime might expand on certain aspects or introduce new elements not present in the manga. Also, the character expressions and interactions might be portrayed differently.
