One more idea is a time - travel fanfic. A Naruto character, say Naruto himself, gets sent back in time to the world of Asura Wrath. He has to adapt to this new world with different rules and powers. At the same time, his presence in that world could change the events of Asura Wrath. And then, when he finally returns to his own world, he brings back new knowledge and powers that he learned in Asura Wrath, which could be used to deal with new threats in the Naruto universe.
A really interesting crossover idea could be a tournament - style story. Characters from both Asura Wrath and Naruto universes are gathered to compete in a tournament. This would allow for all kinds of match - ups. For example, Rock Lee's taijutsu skills against an Asura Wrath character who is also a melee combat expert. It would be exciting to see who would win and how they would adapt their fighting styles.
Imagine a fanfic where the Nine - Tailed Fox in Naruto has some sort of connection to the wrath - based powers in Asura Wrath. Maybe the Nine - Tailed Fox was once influenced by the same energy source that gives Asura his power. This could lead to a whole new arc in the Naruto story where Naruto has to deal with a more powerful and unpredictable Nine - Tailed Fox, and he might seek help from Asura Wrath characters who understand this power better.
One way to blend the worlds is through the concept of power. Asura Wrath has incredibly powerful and god - like beings. In a fanfic, you could have Naruto characters encounter these powerful entities. For example, Naruto himself could meet Asura and learn about a different kind of chakra or power source. This would not only introduce a new element to the Naruto world but also create an interesting dynamic as Naruto's ideology of never giving up might be put to the test against the seemingly invincible Asura.
The plot could involve a tournament in the Street Fighter world where Asura is an unexpected entrant. His over - the - top powers would shock the other fighters. Maybe some of the Street Fighter characters would be intrigued by his raw power and try to learn from him, while others would be jealous. This could lead to various matchups and character development for both Asura and the Street Fighter cast.
The 'asura's wrath reincarnation fanfic' might bring a fresh perspective to the original story. Since reincarnation is a complex concept, the fanfic could play with the idea of memories carried over from one life to another. The writer could explore how the relationships between characters change due to reincarnation. For instance, if a character was an enemy in a past life but a friend in the current one, how would that dynamic be portrayed? It could also show how the world of Asura's Wrath has evolved or changed in different reincarnation cycles.
I think Kakashi from Naruto would be really cool in a fanfiction with Asura's Wrath. His calm and collected nature, along with his Sharingan abilities, could provide some strategic advantages in battles against the powerful foes from Asura's Wrath. Also, Yasha from Asura's Wrath with his loyalty to Asura and his combat experience would be a great character to include for some intense action scenes.
One idea could be exploring their relationship in a modern AU. Imagine Indra and Asura as two brothers in a modern city, dealing with normal life problems while still having their spiritual connection. They could struggle with family expectations, like Indra being the over - achieving older brother and Asura the more laid - back one, but they have to come together to face a common threat that has a connection to their past lives.
Well, one possible interesting plot point could be the combination of Asura's rage - driven powers with the unique fighting styles and energy blasts from DBZ. Maybe there are epic battles where Asura's brute strength meets the ki - based attacks of DBZ characters.
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.
The theme of transformation is quite possible. Not just physical transformation but also mental and emotional. In a reincarnation fanfic, characters may have to adapt to new circumstances, which could lead to significant changes in their personalities. And the theme of karma is also relevant. What goes around comes around, so the actions in past lives could have consequences in the reincarnated lives.
The theme of identity is also prevalent. Asura has to figure out who he is in a new context when he crosses over. For example, if he crosses into a world with different moral values, he has to re - evaluate his own identity. Additionally, the theme of conflict is there. Whether it's a conflict between Asura and the new world's inhabitants or between him and the forces in the new world, it drives the story forward.
Asura's superhuman strength could be combined with Ryu's Hadoken. Imagine Asura powering up a Hadoken with his raw strength, making it an even more devastating attack. It could be like a super - charged projectile that could break through multiple defenses.
