If the characters of 'journey to the west' entered the modern world in a fanfiction, Monkey King would be intrigued by the concept of airplanes, thinking they are some kind of strange flying beasts. He would want to test his strength against them. Tang Sanzang would be appalled by the lack of moral values in some aspects of modern society and would strive to correct it. Zhu Bajie would be in awe of all the different kinds of food and might overindulge. Sha Wujing would be the one trying to keep everyone in line and make sure they don't get into too much trouble.
At first, Naruto might try to reason with the Western side. He would want to understand why they betrayed him. He believes in the good in people, so he would hope that there was some misunderstanding. However, if they continued to be hostile, Naruto would become determined. He would gather his own allies, like his friends from Konoha, and form a resistance against the Western forces. He would use his powerful jutsus and his unwavering spirit to take on those who wronged him.
In fanfiction, the reactions in the Pokemon world to FLIM from MLP would be diverse. The Pokemon that are friendly and trusting, like Eevee, might initially be drawn to FLIM. However, as they get to know him better, they might realize his true nature. The villains in the Pokemon world, like Team Rocket, might see FLIM as either a competitor or a potential tool. They could try to use his skills for their own evil plans. Meanwhile, the regular citizens of the Pokemon world, such as the people in the various towns, would be cautious. They have a peaceful life, and FLIM's arrival with his business - minded and sometimes sneaky ways could disrupt their normal routine. So they would keep an eye on him to make sure he doesn't cause any problems.
The rest of the team would be a mix of shocked and excited. Superboy might be a bit skeptical at first, thinking it could be some kind of trick. But once he realizes it's really Wally, he'd be glad to have another teammate back. Aqualad would probably be more diplomatic, welcoming Wally back but also being cautious about how his return will affect the team.
Well, it depends on the character. A tough, battle - hardened character might be more intrigued than scared. They could see the SCP fanfiction as a new kind of threat or mystery to analyze. However, they might also be disgusted by some of the extreme and unethical elements within the SCP stories. Like a detective character, they would try to make sense of it all but might be put off by the overall dark nature.
Daenerys could view the war as a fight for liberation in some ways. Just as she wants to free the slaves in her world, she might empathize with the countries fighting against tyranny in WW2. However, she would also be horrified by the death toll and the fact that civilians were so often caught in the crossfire.
The Al Bhed in Spira might be the most interested in Harry Potter. They are known for their curiosity and their love for knowledge. They would want to study his magic, his wand, and his robes. They might even try to reverse - engineer some of his magic items. And as for the Ronso, they would likely be initially hostile, seeing Harry as an intruder. But if Harry showed his strength and honor, they could come to respect him.
Naruto himself would probably be excited. He'd see all the magic and different creatures as new challenges and opportunities. He might try to befriend all the familiars and show them his ninja skills.
The Israelites as a whole would likely be in awe. They've lived a simple life in their own time. When they see things like electricity, with lights turning on and off, they would think it's some sort of magic from the future. Some might be scared, thinking it's a sign of something evil. But others, especially the younger ones, would be excited and eager to learn more about these new and strange things.
Some primordials might be quite surprised. In the Percy Jackson fanfiction, the modern interpretations could give them new outlooks on themselves. For example, if they are depicted as having more human - like emotions or motives, it could be a shock. However, they might also appreciate the fresh perspectives that make them more relatable to the modern readers.
Naruto would likely be very curious and excited. He'd probably try to befriend everyone, whether they were humans, demi - humans or monsters. His positive attitude would be a shock to some of the more cynical characters in the Overlord world. Sasuke, on the other hand, would be more guarded. He'd assess the situation and look for ways to gain power. He might see the powerful magic and different races as a means to achieve his own goals.
