The Naruto 12 Wings DxD Fanfic is cool mainly due to the character development. In this crossover, Naruto might gain new traits influenced by the DxD universe. His usual ninja way could be challenged or enhanced by the presence of the DxD's complex power structure. The 12 wings aspect gives him an almost god - like status, which changes his relationships with other characters. He might form new alliances or rivalries with the devils, angels, or fallen angels. This creates a rich tapestry of stories that deviate from the normal Naruto or DxD plotlines.
The contrast. When a fanfic features a weak character in the Naruto DxD universe, it creates an interesting dynamic. For example, seeing a character with less power try to survive in a world full of powerful ninjas and devils makes for an exciting read as they have to rely on their wits more than their strength.
The unique concept. The idea of a wing bloodline in the Naruto world adds a new dimension to the story. It's not something from the original Naruto, so it's fresh and exciting.
The character crossovers are a big part. Imagine Ichigo from Bleach meeting Rias from High School DxD. Their different personalities and goals make for really engaging storylines. Also, the fanfic writers can explore how the characters from one universe would react to the situations and rules of the other universe. For example, how would a Bleach character deal with the peerage system in High School DxD? It opens up a whole new world of possibilities for storytelling that makes these crossovers so interesting.
The clash of different power systems. Naruto's ninja abilities, especially with his immortality, against the unique powers in DxD like the Sacred Gears. It creates exciting battles and strategic scenarios.
The combination of two very different universes. Naruto's ninja world with its jutsus and shinobi culture, and DxD's world of devils, angels and supernatural beings. It creates a whole new set of possibilities for stories.
The character development can be really engaging. The weak devil, starting from a position of weakness, can grow and change throughout the fanfic. Maybe they start as a bullied character but end up being a strong ally. And Naruto's presence can be a catalyst for this change. Also, the exploration of the DxD world from Naruto's perspective, as he tries to understand the devils and their society, adds depth to the story.
The combination of different universes. Highschool DxD has its own unique world of devils, angels, and other supernatural beings. Naruto has ninjas and a complex world of chakra. When you mix Rossweisse from Highschool DxD with the Naruto universe, it creates a lot of interesting possibilities for crossovers. Maybe Rossweisse could learn ninjutsu, or the Naruto characters could interact with the devils and angels from Highschool DxD.
One idea could be that Naruto characters attend the Highschool DxD school. Naruto could use his shadow clone jutsu to cause all kinds of chaos during classes or P.E. Another is that some of the Highschool DxD devils could be interested in Naruto's chakra and try to make a deal with him. Also, the ninjas from Naruto could introduce their unique fighting styles to the students at Highschool DxD, leading to some epic battles in the schoolyard.
The combination of two very different universes, Naruto and DxD, makes it interesting. The Reverse Harem Jutsu from Naruto is a fun element to introduce into the DxD world. It can lead to some really unique and unexpected interactions between the characters from both series.
A really cool crossover idea would be a tournament - style plot where characters from both Highschool DxD and Naruto compete. This would showcase the different fighting styles and abilities. The ninjas' stealth and teamwork could be pitted against the devils' and angels' supernatural powers. It would be a great way to explore how the two very different universes' characters would react to each other in a competitive environment.
