Aquaman is definitely one of the most popular characters. Since the story is centered around Atlantis, he is a key figure. His connection to the underwater world, his powers, and his role in the Justice League make him a central focus in most fanfictions.
Another possible plot is a love story set against the backdrop of the Throne of Atlantis. Maybe a Justice League member, like Wonder Woman, falls in love with an Atlantean noble. But their love is complicated by the political unrest in Atlantis and the impending threat to the Throne. They have to fight against both external enemies and internal opposition to be together while also saving Atlantis.
It's about the Justice League's adventure related to the Throne of Atlantis. There are battles, power struggles, and the exploration of the underwater world of Atlantis.
Some members might be shocked. Wonder Woman, for instance, who respects Batman's skills and tenacity, would likely be very disappointed. She might try to persuade him to stay, emphasizing the importance of his presence in the team. Superman, on the other hand, might initially be understanding, as he knows Batman has his own way of doing things. But he would also be concerned about the power vacuum that Batman's departure would create. Aquaman might be more indifferent, thinking that Batman was always an outsider to some extent, with his focus mainly on land - based issues.
In a Naruto in Justice League fanfiction scenario, Naruto would have a lot to offer. He has a vast amount of chakra which could be used for various purposes like powering up the League's technology or creating barriers. His relationship with his teammates in Naruto like Sasuke and Sakura could be paralleled with the relationships in the Justice League. Naruto might have some initial cultural clashes with the League members as he comes from a different world, but over time, he would learn to adapt and they would learn from his unique skills and way of thinking. His Sage Mode would give him an edge in battles, allowing him to sense danger more acutely and react faster.
He could be a strategic addition. His magic could be used for things like stealth, teleportation, and protection spells for the team. For instance, he could teleport members in and out of dangerous situations quickly.
Definitely not. Justice League is a creation of DC Comics. Marvel Comics has its own set of superhero teams and characters that are distinct from those in the Justice League.
The Flash might initially be in denial. He's used to Batman always having a plan and his death would be a huge shock. He would then turn his speed into a tool for investigation, trying to find out exactly what happened. Green Lantern could feel a sense of loss but also be spurred into action, using his ring to try and prevent future tragedies like Batman's death. He might create constructs in Batman's memory to inspire the team.
One great 'Young Justice Dimension: Justice League' fanfiction is 'The New Recruits'. It focuses on how new members are integrated into the team. The story has great character development and exciting action scenes.
