One interesting plot idea could be that Batman and The Crow team up to take on a new criminal in Gotham. This criminal has a connection to the other side, like The Crow, and is using dark magic to terrorize the city. Batman, with his detective skills, and The Crow, with his otherworldly abilities, would make an awesome duo.
Maybe a plot where The Crow somehow ends up in Gotham and Batman initially mistakes him for a new threat. But as he investigates, he realizes they have a common enemy. The Crow could be seeking revenge on a cult that has ties to both his past and some of Gotham's underworld. This could lead to a complex story of mystery and action as they work together.
A plot idea could be that there's a strange phenomenon in Gotham that is blurring the lines between life and death. Batman is trying to figure it out from a scientific and detective perspective while The Crow is involved because it has something to do with his own undead state. Their different viewpoints could create some great tension and cooperation as they try to solve the mystery and save the city.
Well, you could have a plot where a young, inexperienced ninja accidentally stumbles upon the crow contract. At first, he has no idea how to use it, but as he gradually learns, he forms a deep bond with the crows. These crows then help him in his various missions, and he has to keep their existence a secret from his village because some might see the power of the contract as a threat. Maybe there's also a dark force that is after the contract, adding an element of danger to the story.
A plot could involve the crow clones being used by an enemy to spy on Naruto and his friends. However, the clones gradually develop a sense of loyalty towards Naruto and his cause, and they end up double - crossing the enemy. This could lead to a great battle where the clones prove their worth and become an integral part of Naruto's team.
Perhaps they could start off as rivals in the fanfiction. Batman from the present is skeptical of Batman Beyond's more high - tech approach. But as the story progresses, they learn from each other and become a great team. For example, Batman could teach Batman Beyond some of his old - school detective skills, while Batman Beyond shows Batman new ways to use technology in combat and surveillance.
One idea could be exploring what if Bruce Wayne's identity as Batman was exposed accidentally by a new high - tech surveillance system in Gotham. Another could be a story where Batman has to take on a new identity temporarily to infiltrate a secret criminal organization that has been studying his every move as Batman.
A plot could involve a time - travel scenario where Batman and Supergirl are sent back in time to prevent a major event that would change the future of both their worlds. They would have to work together, using their different skills and knowledge of their respective eras.
One idea could be exploring the relationship between Batman and Robin in a more emotional depth. Maybe Robin is going through a tough time at school and Batman has to balance being a mentor and a crime - fighter. Another could be a time - travel plot where the Bat - family gets sent to different eras in Gotham's history and has to adapt and still fight crime.
One idea could be that Batman and Robocop team up to take on a powerful criminal organization that is using high - tech weaponry. They would combine Batman's stealth and detective skills with Robocop's firepower and law enforcement programming.
One idea could be Batman using his detective skills to uncover a hidden threat that the Avengers initially overlook. For example, he might notice some small, seemingly insignificant details during a battle scene that lead him to a much larger conspiracy.
One idea could be exploring the psychological state of Batman during Knightfall more in - depth. Maybe focus on his nightmares and how they affect his decisions in the story. Another could be a what - if scenario where a different character takes on the role of protecting Gotham during Knightfall, like Oracle guiding a team of young vigilantes.
One idea could be exploring Batman's internal struggle in the Injustice universe more deeply. Maybe he has a nightmare where he becomes like the tyrannical Superman, and this makes him question his own actions and methods even more.
