A possible plot for the Naruto DC Comics crossover fanfiction could be that the Akatsuki from Naruto are hired by a DC villain, say Lex Luthor. The Akatsuki members start causing mayhem in the DC Universe, stealing valuable resources for Luthor. Naruto and his comrades then have to team up with the Justice League to stop them. This would lead to some interesting battles, like Kakashi vs Green Arrow in a battle of archery skills, or Sasuke's Sharingan against Martian Manhunter's telepathy.
One idea could be that Naruto and his friends are transported to the DC Universe. Naruto's chakra could be seen as a form of magic in the DC world.

Another plot could involve Batman being intrigued by Naruto's ninja skills and trying to incorporate some of them into his own combat style.
One idea could be that Naruto, with his Mokuton abilities, gets transported to the DC universe. He might team up with Green Arrow in Star City.

Naruto might try to convince her to use her powers for good instead of causing chaos.
One idea could be Goku ending up in the DC universe and having a friendly spar with Superman. Their different power sources and fighting styles would make for an exciting encounter. Maybe Goku learns about Kryptonite and how it affects Superman, which gives him a new perspective on weaknesses.

Then, Harry and the likes of Superman, Batman, and Wonder Woman would have to combine their magical and super powers to stop them.
