They can start by observing the new world's culture. Just like when we travel to a new place in our world, the OC can watch how the people interact, what their values are. For example, if the new world values honor above all else, the OC can try to uphold that in their actions.
The OC should also be open to new experiences. Instead of being afraid of trying new things like eating strange foods or using new forms of transportation, they should embrace them. This not only helps them adapt but also shows the locals that they are willing to be a part of their world. For example, if the new world has flying beasts as a mode of transport, the OC should be brave enough to ride one.
He would first have to get used to the presence of vampires and werewolves. This means understanding their rules, like the vampires' need to drink blood and the werewolves' transformation during the full moon. He might also have to adapt to the small - town atmosphere of Forks, which is very different from modern - day big cities.
Percy would first use his combat skills. If he's in a dangerous world, he'll rely on his fighting abilities. He might also try to find allies quickly. After all, he's used to having friends around in his own world.
One idea could be that the OC discovers they have a special power in the new world that is key to saving it from an ancient evil. For example, the power to control time, which is a very cool concept.
Well, it could be really exciting. The OC might find themselves in the middle of all the action and drama in the RWBY world. They could form unique relationships with the different characters. Maybe they'd team up with Ruby and her friends against the Grimm. And in the harem aspect, they could have some interesting romantic or friendly interactions with multiple characters, like Weiss, Blake, and Yang.
The OC might interact with them in various ways. They could start by being in awe of their combat skills, like Ruby's speed. And in the harem aspect, they could show affection differently to each character. For Weiss, it could be through respecting her family name and helping her with her studies. With Blake, they might bond over books and their love for knowledge.
If Elsa is transported to the real world in fanfiction, her adaptation would be a journey. Initially, she'd be shocked by the noise and crowds. But she has a strong will. She'd learn about different cultures and languages. She might use her ice powers in creative ways, like making an ice rink in a park. This would help her gain acceptance. And she'd also make friends with those who are kind and curious about her, which would further aid her in adapting to this strange new world.
An OC could fit in by having useful skills. Like being good at hunting or knowing how to make weapons. That would make them valuable to the group in the fanfiction.
First, find a reliable water source. Water is essential for both you and your Pokemon. Then, look for a place to shelter, like a cave or an abandoned building. Try to catch a Pokemon as soon as possible for protection. A Pokemon like Geodude can be a good start as it's relatively easy to find and can be strong in defense.
The reader should first keep calm. Then, try to recall the knowledge about the Avengers from the fanfictions they've read. It'll help them understand the situation better.
The new world could be a medieval - style realm filled with knights, castles, and magic. Percy might find himself in the middle of a war between kingdoms, using his skills to survive. Maybe there are mythical creatures like dragons and unicorns there.
