Well, a cool crossover idea in the fanfiction could be Naruto teaming up with Batman. Naruto's positive and determined attitude could influence Batman's rather brooding nature. In a fight, Naruto could use his Rasengan against the Arkham Knight's high - tech weaponry. And his shadow clone jutsu would be great for confusing the enemies in Gotham's complex alleys and rooftops.
In a Naruto - Batman: Arkham Knight fanfiction, a possible crossover could be that Naruto gets transported to Gotham. He might be initially confused by the high - tech environment but quickly adapt. His chakra could be seen as a new kind of power in Gotham. He could learn from Batman's detective skills and in turn teach Batman some ninja techniques. This would create a really unique dynamic between the two characters.
One interesting story could be about Batman's internal struggle with the darker side of Gotham while facing the Arkham Knight. It might explore how he overcomes his doubts and fears in a more personal way than in the game.
One interesting 'Batman Arkham Knight' reaction fanfiction could be about how the citizens of Gotham react to Batman's final showdown with the Arkham Knight. It might explore their fear, hope, and the impact on the city's future.
One idea could be exploring how the Knightfall event affects Batman's relationships with his allies in the Arkham Knight universe. Maybe some of them start to question his methods more deeply.
One interesting plot idea could be a fanfiction where the Joker somehow comes back to life in Arkham Knight. Maybe he was only in a coma and wakes up with a new, even more deranged plan to take over Gotham. He could start by manipulating the inmates in Arkham again, creating chaos from within the asylum.
In this fanfiction, it could be interesting if Catwoman discovers a secret about the Arkham Knight that Batman has overlooked. She could use this knowledge to her advantage, either to make a deal with the Arkham Knight or to help Batman. For example, she might find out that the Arkham Knight has a weakness related to a certain location in Gotham that was important to his past. Catwoman could then lead Batman there to take down the Arkham Knight.
A possible crossover could involve the settings. The Hidden Villages in Naruto could be the backdrop for Moon Knight's adventures. Picture Moon Knight in Konoha, dealing with the ninja politics and perhaps even learning some ninja techniques. He could team up with Naruto and the other ninjas to face a common enemy, like a new villain that combines the dark magic from Moon Knight's world with the ninja arts of Naruto's world.
A crossover might involve Sasuke from Naruto in the Vampire Knight universe. Sasuke's search for power could be paralleled with the vampires' thirst for blood or power in their own world. He could encounter the vampire hunters and perhaps form an unlikely alliance with them, seeing as he has his own vendetta against those he deems as powerful enemies. The idea of Sasuke using his Sharingan in a world full of vampires and their unique abilities would make for an exciting story.
Well, a great plot idea might be delving deeper into the relationship between Batman and his rogues gallery in the aftermath. For example, how the villains react to Batman's continued presence or absence. Some might see it as an opportunity to take over Gotham, while others might be secretly glad he's still around to keep a certain order. Also, exploring the technological fallout. With all the advanced tech used during Arkham Knight, there could be some unforeseen consequences like tech falling into the wrong hands or new, unexpected uses for it.

A great plot idea for this fanfiction could be that Harley Quinn is haunted by the memories of her time with the Joker during the Arkham Knight scenario. Batman, noticing her distress, tries to help her. As they interact more, Harley starts to see Batman in a new light and decides to assist him in his fight against the Arkham Knight. Along the way, they face many challenges, like dealing with Harley's old gang who don't trust her new alliance with Batman, and also the Arkham Knight's devious traps. This would make for a complex and engaging fanfiction story.
