A 'devil may cry 4 crossover fanfiction' could be really interesting. It might involve characters from 'devil may cry 4' interacting with characters from other universes. This could lead to some really unique storylines. For example, Dante from 'devil may cry 4' could team up with a character from a different action - adventure game. The fanfiction could explore different power combinations and how they would work together in battles.
One idea could be that Dante from Devil May Cry is somehow transported to the Marvel universe. He teams up with the Avengers, like Iron Man. Dante's unique combat style and devil - slaying abilities would be a great addition to the team. For example, he could use his Rebellion sword against powerful foes that the Avengers are having trouble with, such as Loki if he were to return in a more powerful form.
One popular theme is power - up crossovers. For example, Nero from 'devil may cry 4' might gain new powers from another character in a different franchise. This makes the battles more exciting and gives new dimensions to his character.
A good crossover idea might be that some of the Devil May Cry characters get transported to the Naruto world. Dante could be mistaken for a very powerful ninja with his flashy moves. He could then team up with Naruto to fight against an enemy that is causing chaos in both the ninja world and has some connection to the demon world. Maybe they have to stop a powerful demon from taking over the bodies of the ninja.
One idea could be that Naruto somehow ends up in the Devil May Cry world. He might mistake some of the demons there as similar to the tailed beasts he knows. For example, he could try to 'befriend' a demon in the DMC world thinking it's like how he dealt with Kurama. Another idea is Dante teaching Naruto some swordsmanship. Dante's flashy and powerful combat style could blend well with Naruto's own energetic fighting moves.
One possible plot is that there's a powerful demon in the Naruto universe that has a connection to the underworld of Devil May Cry. Naruto and his friends seek help from Dante and Vergil. Along the way, Naruto learns about the different types of demons in the Devil May Cry world and how to combat them using his chakra in new ways. The story could be filled with intense battles and character development as they all try to stop the demon's evil plan.
It could be a powerful demon lord who wants to conquer both the Naruto universe and the Devil May Cry world. This demon lord might have the ability to manipulate chakra and also use demonic powers, making it a formidable foe for both Naruto and Dante.
Naruto's ability to create shadow clones would be very useful. He could send clones to scout out areas full of demons, or use them as distractions in battle. His rasengan could be a powerful close - range attack against demons. Also, his chakra control could potentially be used to enhance Devil May Cry weapons, like making a sword cut through tougher demon hides more easily.
I think Naruto and Dante would be an interesting pairing. Naruto's positive and determined attitude would contrast with Dante's more laid - back but still badass demeanor. They could learn a lot from each other in combat. Another interesting pairing could be Sasuke and Vergil. Both are brooding characters with a thirst for power, and their meeting could lead to some intense power struggles or even a begrudging mutual respect.
Another reason might be that they faced some sort of writer's block. Coming up with new plot ideas, especially for a crossover as complex as Naruto and Devil May Cry, can be really challenging. They might have hit a point where they didn't know how to progress the story further. Or perhaps they received some negative feedback early on that discouraged them from continuing.
