One possible plot for this fanfiction could be that Naruto, as Darkseid's brother, is sent to the Naruto universe as a sort of experiment or exile. He has to adapt to the world of ninjas, hiding his true origin. As he becomes a great ninja, his connection to Darkseid starts to surface. The Akatsuki could be interested in his powers related to Darkseid. Naruto then has to fight against the Akatsuki while also trying to figure out how to deal with his brother. He might try to find a way to use his Naruto - like positive attitude to change Darkseid's evil ways.
In this fanfiction, Naruto's character would experience significant growth. He'd be forced to confront the idea of family in a whole new light. His concept of good and evil would be challenged. Naruto, who has always been about protecting his friends and the village, now has to think about a much larger scale. He might start to question his own identity and purpose. His development would also involve learning about Darkseid's powers and trying to use them for good. He could become more of an outcast as some in the ninja world fear his connection, but this would only strengthen his resolve to prove himself. His journey would be filled with internal struggles and external battles, all of which would shape him into a more mature and complex character.
In this fanfiction, perhaps Naruto as a Darkseid clone discovers new powers. Since Darkseid is a powerful being in the DC universe, Naruto could inherit some of that raw power. He might have to learn to control it, just like he learned to control his chakra. His friends in the Naruto world could be either afraid of him or try to help him come to terms with this new identity.
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.
Well, it could be that Naruto is somehow transported to the Asgardian realm. Maybe Thor discovers Naruto and they realize they have a strange bond like brothers. They could team up to fight against common enemies from both of their worlds, like Naruto using his ninja skills and Thor with his godly powers.
Naruto would probably have a more complex view of power. In the original, he was all about becoming stronger to protect his friends. But as a Darkseid clone, he might question the nature of power. Darkseid uses power for domination, and Naruto would have to struggle not to be influenced by that aspect while still using his new - found powers for good.
Well, it could be really interesting. Maybe Naruto, with his ninja skills and strong sense of justice, enters the Twilight world and discovers he has a sister in Rosalie. He might use his abilities to protect the Cullens from their vampire enemies. And Rosalie could learn some things from Naruto about loyalty and perseverance.
One possible plot could be that the twin brother has a very different personality from Naruto. Maybe he is more reserved and studious while Naruto is brash and energetic. The twin could secretly be training in a different type of jutsu, perhaps more focused on genjutsu while Naruto is into rasengan and other offensive ninjutsu. Their relationship might start off rocky as they compete for recognition in the village, but eventually they come to realize they are stronger together and support each other in battles against powerful enemies.
One possible plot could be that Darkseid somehow discovers the wizarding world. Harry Potter, being the central figure, might be targeted by Darkseid. Darkseid could see Harry as a potential threat or a tool for his power - hungry plans. Harry, on the other hand, would have to use his magic in ways he never thought before to fight against Darkseid's forces, which could include his minions from the DC universe.
His sense of justice could be warped. Naruto has always fought for what he believes is right, but as a Darkseid fan, he might start to think that power is the ultimate arbiter of right and wrong. This could lead him to make decisions that are more self - serving rather than for the good of the village. For example, he might pursue power at all costs, even if it means sacrificing the safety of his friends in the short term to gain more strength in the long run. He would become more calculating and less impulsive in his actions, which is a big change from his usual head - first style of dealing with problems.
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.
