A storyline could involve Nightwing being framed for a crime in Gotham. Batman, believing the evidence at first, tries to bring him in. Nightwing, of course, resists as he is innocent, and this leads to their fight. As the story progresses, they both realize there's a bigger conspiracy at play.
In this fanfiction, often there's a power struggle. Nightwing, with his own set of skills and experiences independent from Batman, might oppose Batman on certain principles. Maybe it's about different approaches to crime - fighting. Nightwing could be more lenient while Batman is strict.
In this fanfiction, often there are intense power dynamics at play. Batman, Nightwing, and Robin each have their own unique fighting styles and moral compasses. Batman is the experienced and brooding mentor, Nightwing brings his acrobatic and more independent style, while Robin might be the young, eager one trying to prove himself. Their conflicts can stem from differences in how they approach crime - fighting and justice.
One possible storyline could be that Batman discovers a conspiracy within the Justice League that endangers Gotham. So he and Robin decide to take on the League to stop it. Another could be that the Justice League is being mind - controlled, and Batman and Robin are the only ones who realize it and try to free their friends by fighting them. Or perhaps there's a misunderstanding where the Justice League believes Batman and Robin have turned bad, and they have to fight to prove their innocence.
Power struggles are quite common. Batman has his own way of doing things, and Nightwing and Robin may want to assert their own identities and methods. It's like a tug - of - war between the generations. Also, the theme of family is always there. They are like a dysfunctional family, and their conflicts are like family feuds that ultimately strengthen their bond.
One reason could be the inaccurate characterizations. Fanfiction writers might not fully understand the nuances of Nightwing or Batman's personalities, and Nightwing hates seeing a wrong version of them. For instance, if Batman is made too soft or too harsh in a way that doesn't match the established canon.
One interesting storyline could be Catwoman stealing a valuable artifact that has a connection to Batman's past. This forces Batman to track her down, but as he does, he discovers that Catwoman has her own reasons for taking it that are more complex than simple theft. Another could be a situation where Catwoman and Batman are forced to team up against a greater threat in Gotham, like a new super - villain who is out to destroy the city. And a third one might be a story where Catwoman tries to frame Batman for a crime he didn't commit, leading to a tense cat - and - mouse chase between them.
Maybe there's a storyline where they team up against a common enemy. A powerful criminal who uses both high - tech gadgets like Batman's villains and has a dark, serial - killer - like mind like Dexter's prey. They have to combine their skills, Batman's detective work and combat skills with Dexter's forensic knowledge and ability to blend in.
Perhaps there is a powerful artifact that both Spiderman and the Avengers are after. They end up in a conflict over it. Spiderman, with his street - smart ways, tries to outwit the Avengers and get the artifact for himself, believing he can use it for good in his own way.
One possible storyline could be that Thanos arrives on Earth seeking a powerful artifact. Superman steps in to stop him. They battle it out across the city, with Superman using his strength and speed to try and take down Thanos. Another could be that Thanos somehow manages to get Superman under his control using the Infinity Stones, and then the rest of the Justice League has to figure out how to free Superman and defeat Thanos.
It can symbolize protection. Batman is the mentor, and when he carries Nightwing, it shows his instinct to keep Nightwing safe from harm, whether it's physical harm from villains or other threats.
