What could be an interesting plot in a 'naruto saiyan justice league fanfiction'?

Well, one possible plot could be that Naruto somehow gets transported to the DC Universe where the Justice League operates. He meets the Saiyans who are also there for some reason, like a universal rift. They all have to team up to fight a common enemy that is threatening both the Naruto world and the DC world. Maybe it's a powerful demon from Naruto's world that has gained new powers in the DC Universe and is causing chaos.

A plot could involve the Saiyans teaching Naruto some of their combat techniques and in return, Naruto shows them some of his ninja skills. Then, the Justice League discovers this new group of powerful individuals. At first, they are cautious, but when they realize they are all on the same side against a big bad like Darkseid who has also got his hands on some ninja magic, they join forces. The story could be about how they combine their powers and strategies to take on this super - powerful foe.

Perhaps in this fanfiction, there is a prophecy in both the Naruto world and the Saiyan's world that is related to the Justice League. It foretells that a group consisting of Naruto, Saiyans and the members of the Justice League must come together to save all the universes from being merged into a chaotic mess. They initially struggle to work together due to their different cultures and ways of fighting, but as they face various challenges along the way, they start to understand and respect each other, and finally manage to fulfill the prophecy.
