In a fanfic, Captain America could fit into the Justice League by being the voice of the common man. The Justice League often deals with big, cosmic threats, but Captain America would remind them of the importance of protecting the ordinary people on the ground. His experience in World War II gives him a unique perspective on the cost of war and the value of peace, which could influence the Justice League's decisions when it comes to using force and resolving conflicts.
Perhaps in the fanfiction, a cosmic event causes a rift between the Marvel and DC universes. Captain America and the Justice League find themselves on the same side as they are the only ones who can prevent the destruction of both universes. They must overcome their differences in ideology and power - sets. Captain America's sense of justice and the Justice League's diverse powers and abilities would make for an interesting dynamic as they work together to close the rift and defeat the forces trying to destroy the universes.
He'd fit in terms of values. Steve stands for truth, justice, and the American way, which is not too far from what the Justice League represents. His physical abilities, while not as super as some of the League members, are still impressive and his combat skills would be useful.
It could be really interesting. Steve Rogers' sense of justice and leadership would blend well with the Justice League. His military tactics could help in planning battles against powerful villains. For example, in a fight against Darkseid, Steve might come up with a strategy to use the different powers of the League members effectively, like having Flash create distractions while Superman goes for a direct attack.
They would probably be very concerned. They might first check his vital signs to make sure he's okay. If they find nothing physically wrong, they'd start to consider other possibilities like magic or mind - control.
In such a fanfic, perhaps the other members of the Justice League might start to worry about Captain Marvel. They could think it's some sort of strange attack or the result of a new, unknown power affecting him. They might gather around him, trying to figure out what's wrong while also keeping an eye out for any potential threats.
One plot idea could be Captain America joining the Justice League temporarily. He could bring his military tactics and sense of honor, and have clashes and then reconciliations with Batman over leadership and strategy. For example, when facing a powerful alien invasion, Captain America might advocate for a more direct, all - out attack while Batman prefers a more stealthy, long - term plan.
I think Captain America and Batman would have some great interactions. Batman is the dark and brooding detective, while Captain America is the all - American hero. They could clash over their methods of fighting crime at first. Batman might be skeptical of Captain America's more straightforward and moral - centered approach, but over time they could learn from each other and form a strong partnership.
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.
