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.
One possible fanfic could involve a battle against a powerful villain. Nightwing might get injured while trying to protect Gotham. Batman then has to step in not only to defeat the villain but also to take care of Nightwing. He could use his advanced medical knowledge and resources in the Batcave to nurse Nightwing back to health.
In the Injustice 2 Batman ending story, Batman manages to defeat Superman. He restores order to a world that has been torn apart by the chaos of the Injustice regime.

He also has to deal with the remaining super - villains and ensure that they are locked away safely.
I would recommend 'Nightwing's Ascent'. This fanfic is amazing as it focuses on Nightwing's growth while still maintaining his connection with Batman. It has some really cool action scenes and emotional moments that make it a great read.
It's possible that such fanfiction exists. In the world of fanfiction, creators often experiment with different character dynamics. But in the traditional Batman and Nightwing relationship, Batman is more of a guiding figure to Nightwing. The idea of Batman being abusive is a deviation from the norm. It might be a way for some writers to add drama or explore the psychological impact on Nightwing if such a situation were to occur, but it's not in line with the general perception of their relationship.
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.
There's a fanfiction called 'Nightwing: Gotham's Shadow'. In this story, Nightwing is dealing with a new threat in Gotham that Batman is somehow oblivious to. It's an interesting take as it shows Nightwing's independence and his unique approach to protecting the city. It also has some great interactions with other Gotham characters.
One great 'batman x nightwing fanfiction' is 'A Bond Beyond the Cape'. It really delves into their complex relationship, showing how Nightwing's growth from being Batman's sidekick has shaped their dynamic. It has some really well - written action scenes and emotional moments that fans of the duo will love.
The relationship between Batman and Nightwing is key. Their different personalities - Batman's brooding and Nightwing's more upbeat nature - create a great dynamic. Also, the action in Gotham, like taking on classic villains together, can be really exciting.
