In this fanfiction, the plot could involve Darkseid seeing Batman as a unique asset among Earth's heroes. He makes Batman his advisor to gain an edge in his battles against other cosmic entities. Batman, on the other hand, is in a tough situation where he has to balance his moral code with the demands of Darkseid. He might use this position to try and protect Earth in ways that Darkseid doesn't anticipate.
Batman's character would experience a significant transformation. Initially, he would be resistant to the idea of being Darkseid's advisor. However, as time goes on, he would adapt to the situation in order to survive. His moral compass would be severely tested as he would be forced to make decisions that go against his usual principles. He might become more calculating and less trusting of others, even his own allies. This new experience could also give him a deeper understanding of the cosmic threats that exist beyond Gotham, which could potentially change his approach to protecting the world once he manages to break free from Darkseid's grasp.
Batman would be in a tough spot. Darkseid is extremely powerful. But Batman is not one to give up easily. He might try to analyze Darkseid's powers and find a way to counter them, even in captivity.
Well, one possibility could be that Naruto, being the son of Darkseid, has to struggle with his dual nature. He might have the powerful abilities of Darkseid like Omega Beams but also the kind heart of Naruto. He could be in a constant battle within himself to decide whether to use his powers for domination like Darkseid or for protection like he always did in the Naruto world.
If Batman were to join Darkseid, it would be a huge shift in the DC universe. Batman is known for his strong moral code and fighting against evil. Joining Darkseid would mean he has to abandon his principles. Maybe he's forced to do it under some mind - control or a desperate situation to save Gotham in a way he thinks only Darkseid can help. But it would also make him a target for all his former allies, like the Justice League.
One possible plotline could be that Darkseid is about to destroy Gotham or Earth in a way that Batman has no other option but to kill him. Maybe all of Batman's usual gadgets and allies are useless, and he has to use a kryptonite - like weapon (if it could affect Darkseid) to take him down.
Well, if Darkseid kidnaps Batman in a fanfiction, it could lead to an interesting exploration of Batman's character. He'd be out of his element, in Darkseid's domain. But Batman has a strong will. He might try to understand Darkseid's motives while looking for an opportunity to turn the tables. It could also show how the other characters in the Batman universe react to his disappearance.
One possible plot could be that Harry discovers his true parentage as the son of Darkseid. He might struggle with his newfound identity and the dark powers within him. He could be torn between the wizarding world he grew up in and the dark influence of his father. This could lead to him trying to find a way to use his powers for good, or he might be tempted to embrace the dark side at times.
Well, it might be that in the fanfiction, there's a parallel universe where Batman's parents didn't die. So he meets them in this alternate reality. He has to adjust to a world where he doesn't need to be the brooding vigilante. Instead, he gets to experience a normal family life, but he also realizes the importance of his role in his own universe and takes some valuable lessons back with him.
In the fanfiction, the daughter might be from an alternate timeline. Batman meets her when she accidentally travels to his Gotham. She has her own set of skills, which she learned from stories about her father. They team up to fight a new supervillain who is threatening the city, and during this time, Batman realizes how much he missed out on having a family life.
In such a fanfiction, the story might develop as Batman discovers secrets about Darkseid that he thinks he can use to his advantage. He could be playing a long - game, pretending to be on Darkseid's side while actually planning to bring him down. However, Darkseid is no fool and would likely test Batman's loyalty. Meanwhile, the rest of the DC universe would be in chaos as they try to figure out why Batman has turned and how to stop him if he's truly gone bad.
