One possible adventure could be that the human gets involved in the War of the Ring. Maybe they join the Fellowship by accident, not fully understanding the significance at first. They could use their unique skills from the modern world, like basic first - aid knowledge, which might come in handy during battles or on the long journey.
The human might also find themselves in a small village in Middle - Earth. There, they help the local farmers improve their agricultural techniques. They could introduce new methods of irrigation or crop rotation. In the process, they become an important part of the community and are eventually recognized as a valuable asset when the village faces threats from orcs or other dark forces.
He might encounter unique and dangerous beasts in Uzushiogakure. Fanfiction often has new and exciting creatures for the protagonist to face, and Uzushiogakure's different environment could be home to such beasts.
They could have adventures like learning new jutsus. Maybe they meet some of the famous ninjas in Konoha and get trained by them. They might also explore the unique places in Konoha, such as the Hokage Monument.
She could have an adventure related to the Nile River, which is full of mystery and magic in the wizarding world. There might be magical guardians protecting certain parts of it. Also, in Egyptian fanfiction, the architecture is often a big part of the story. She could be exploring ancient temples and palaces that are full of hidden passages and magical artifacts. Her femininity might also play a role, perhaps she'll be treated differently by the Egyptian magical society as a female wizard compared to how she was treated in the male - dominated British wizarding world.
Well, in an Ash goes to Pokemon school fanfiction, there could be a lot of fun interactions. Ash is used to traveling and learning on the go. At school, he'll likely get into some friendly rivalries. He might also discover new types of Pokemon that he hasn't seen much in his travels. And who knows, he could even start a Pokemon club at school.
She could meet a time - traveler. This would open up a whole new set of adventures as they journey through different eras together, trying to fix historical events that have been altered by villains. It would be a great opportunity to explore different time periods and how Supervirl's powers interact with the rules of time.
Perhaps they embark on an adventure to stop a time - traveling villain who is trying to change the course of Vongola history. Tsuna and Giotto would have to travel through different time periods themselves to track down this villain. This would expose Tsuna to different eras of the Vongola's existence and give Giotto a glimpse into the future of the family he founded. They would face many challenges, but their combined strength and determination would see them through.
It could be full of surprises and unexpected challenges. Maybe they encounter advanced technologies or face new enemies they never imagined.
A human could be a healer. Given that Middle - Earth has its own forms of medicine, the human could bring in different approaches. They might use herbal remedies from their own knowledge combined with the local plants. This could be especially useful in treating wounds after battles or during plagues.
In this kind of fanfiction, Percy Jackson would bring his unique demigod skills to the army. Maybe he'd use his water - controlling abilities to help in situations like creating water barriers or putting out unexpected fires. His combat skills, honed from fighting monsters, would make him a formidable soldier. He could also use his ability to sense danger to warn his comrades of impending threats.
Ash could meet new friends. The city is filled with different kinds of people. Maybe he'll meet a trainer with a completely different approach to Pokémon battles, which could inspire him to improve his own skills. He might also meet locals who can show him around and introduce him to the hidden gems of Altomare.
