One great 'sent to another world' novel is 'Re:Zero - Starting Life in Another World'. It has a unique plot where the main character, Subaru, keeps dying and restarting in a different world, which makes for a really engaging read.
In such a fanfiction, Naruto might use his ninja skills to quickly adapt in the new world. He could make new friends and enemies. His chakra abilities would be a great advantage, perhaps making him a sort of legend in that world.
Definitely 'Overlord'. It has a really interesting concept where a player in a virtual world gets sent to the world of the game. The main character, Momonga, is a powerful sorcerer, and the story shows how he uses his skills and knowledge to rule over the world. It's very popular for its world - building.
The novel I recommend is "The Extraordinary Records of Abraham". The protagonist of this book, Huang Xin, was summoned to a magical world created by a transmigrator and became someone else's elemental contract spirit. He had signed a contract with the Dark Elves, which could help him solve many problems and crises. I hope you like this fairy's recommendation. Muah ~😗
Power - up or growth is also a big theme. They start from being relatively weak or normal in their own world and then gain new abilities and knowledge in the other world. For example, in many such novels, the protagonist learns magic or combat skills they never had before. This growth is usually tied to their adventures and challenges in the new world.
Naruto adapts by using his determination. He's used to facing challenges in his own world, so he applies the same mindset in the new world. He also tries to learn about the new culture and rules quickly. For example, if the new world has a different form of combat, he observes and practices.
Naruto adapts to the new world through a series of steps. Initially, his natural curiosity drives him to explore the new environment. He is not one to shy away from new things, so he actively seeks out knowledge about the new world. His experience in facing difficult situations in his own world gives him the confidence to face challenges in this new place. He may face some setbacks, like not being able to communicate effectively at first, but he perseveres. He also uses his ninjutsu in different ways, for example, if there are magical elements in the new world, he tries to combine his chakra - based techniques with them. Moreover, his ability to empathize with others, which he developed in his own world, helps him build relationships in the new world, which is crucial for his adaptation.
If you were struck by lightning and went to another world, you could refer to the following description:
When night fell, a bolt of lightning streaked across the sky and lit up the ground. Suddenly, there was a loud bang accompanied by a strong vibration. People looked up at the sky in horror. Not long after, they discovered a strange phenomenon: lightning bolts began to appear where they were, accompanied by strong tremors.
As the lightning and tremors continued to intensify, people felt their bodies begin to change. Their bodies became abnormally strong and they also obtained the strength and skills of the other world. They discovered that they could control the elements of nature, such as wind, water, fire, and earth.
There were all kinds of magical creatures and species in this foreign world. Some of the creatures were ordinary humans, while others were gods and demons from other worlds. In this world, humans faced all kinds of challenges and dangers, but they also had powerful strength and skills to fight against foreign creatures.
Being struck by lightning and sent to another world will bring the protagonist a series of strange experiences and challenges, making them a legendary figure in this world.
In Naruto sent to another world fanfiction, a plot twist could be that the new world's technology or magic nullifies Naruto's normal powers, forcing him to adapt and develop new skills. This could lead to him having to rely on his wits more than his strength. Another twist is that he gets involved in a political struggle in the new world that is eerily similar to the ninja village politics he left behind. And sometimes, he might be the key to a mystery in the new world that has been unsolved for centuries, which changes his role from an outsider to a central figure.
One interesting plot could be Percy finding himself in a world where the Greek gods have different forms or powers. For example, Zeus could be a benevolent king instead of the often angry god we know. Percy would have to navigate this new world, figure out how to use his own powers in relation to these changed deities, and perhaps find a way back home. Another plot could involve Percy being sent to a world that is a blend of different mythologies, like Greek and Norse. He'd have to deal with new creatures and gods from both mythologies, which would be a real challenge.
