Naruto, Rikudou Sennin and Justice League Fanfiction: How could they interact in a crossover?

In a fanfiction, the Rikudou Sennin could have foreseen a future threat that neither the Naruto world nor the DC universe could face alone. So, he sends Naruto to the DC universe to recruit the Justice League. Naruto has to convince the skeptical heroes to come back with him to his world. Once there, they find that the threat is a combination of powerful ninja - based villains and some of the DC super - villains who have joined forces. They must then work together, with Naruto and the Justice League using their respective powers and skills to defeat this new alliance.

The Kyuubi within Naruto represents a powerful and often uncontrollable force. In a crossover with the Justice League, this could be a source of both conflict and cooperation. The League might be wary of the Kyuubi's power, but Naruto's willpower to control it could earn their respect. They could work together to fight a common enemy that is drawn to the unique power that Naruto and the Kyuubi possess. Maybe an alien threat that wants to harness the Kyuubi's chakra for its own evil purposes. Naruto could use his Rasengan and other jutsu in combination with the League's powers, like Superman's strength or Batman's strategic mind, to defeat this enemy.

Yes, in some fanfictions, Naruto can be depicted as the Rikudou Sennin. Fanfiction writers often take creative liberties and come up with unique storylines where Naruto might inherit the powers or even be reincarnated as the Rikudou Sennin to explore different plot developments and character arcs.

One possibility is that Naruto has a spiritual journey with Rikudou Sennin. They could travel through different time periods related to the history of the ninja world. Naruto would see first - hand how the world came to be the way it is. And through this journey, Naruto's understanding of his own purpose and the ninja way could be deepened. Rikudou Sennin might also reveal some hidden prophecies or destinies that Naruto has to fulfill.

One implication is that Naruto would have an extraordinary amount of power. He could potentially reshape the ninja world more easily. For instance, he might be able to end all wars and conflicts with a snap of his fingers.

It could be a powerful dark ninja who has discovered a way to tap into an ancient and evil power source. This ninja wants to use this power to rule the ninja world and sees Rikudou Sennin's rebirth as a threat to his plans.

One interesting plot could be that Rikudou Sennin is reborn into a time when the ninja world is on the verge of a new, unknown threat. He has to quickly regain his powers and knowledge to guide the new generation of ninjas, like Naruto and his friends, to face this threat. Maybe he has lost some of his memories in the rebirth process, adding an element of mystery and self - discovery to the story.

He might interact with them in a very interesting way. He could be a mentor figure to some of the younger characters, like Issei. Given his vast knowledge and power, he could teach them about different forms of energy and combat techniques. He might also be a bit of an enigma to the devils, angels, and fallen angels, as his powers are so different from what they're used to.

Rikudou Sennin's chakra could be seen as a unique power source by the DxD characters. For example, devils might try to make pacts with him to gain access to his chakra. His ability to manipulate the Six Paths powers could also give him an edge in battles against the various beings in the DxD world. He could potentially use his power to nullify some of the abilities of the angels or fallen angels.

One possible plot could be that Rikudou Sennin somehow gets transported to the world of Highschool DxD. Maybe his powers disrupt the balance there. For example, his chakra could be mistaken for some kind of new and strange power in the DxD world. The characters in DxD might initially be wary of him but then start to see the potential of his abilities and try to recruit him for their own purposes.
