I think this story might be about a man with a very special existence, perhaps defying the normal concept of birth. Maybe it explores themes like identity and the nature of existence in a unique way.
One possible theme could be isolation. Since he was never born in the normal sense, he might be isolated from others who have a traditional birth and upbringing.
In some fanfictions, if Naruto was born in Ame, he might have a very different upbringing. He could be exposed to the harsh environment and unique culture of Ame from the start. This might make him more cynical or street - smart compared to his original self in Konoha.
Well, if Naruto was born a girl, it might change how she's perceived by the village and her interactions with other characters. It could also affect the way she develops her skills and powers.
Well, Naruto might become a Pokémon trainer. He has that never - give - up spirit which would help him catch and train strong Pokémon. He could start his journey in a place like Pallet Town, meet Pokémon like Pikachu right from the start. And his ability to make friends quickly would also mean he'd have a great team of Pokémon and human friends in no time.
If Snape was never born, the whole dynamic at Hogwarts would be drastically different. Snape played a crucial role in the balance of power between the good and the bad. Without him, Voldemort might have had an easier time infiltrating Hogwarts. Also, Harry might not have had someone constantly on his case, which could have led to a different kind of growth for him.
One great 'Harry Potter WBWL' fanfiction is 'The Boy Who Lived?'. It explores a world where Voldemort was never defeated by Harry. Another one could be 'A Different Destiny' which delves into how the wizarding world changes without Harry around. And 'The World Without Harry' is also interesting as it shows how different characters' lives are altered in this alternative scenario.
Well, it could be really interesting. The OC might have different jutsu training based on the village's specialty. For example, if born in Kirigakure, they might be trained in water - based jutsu from a young age. Their values could also be different, like in Konoha they might value friendship and teamwork highly, but in Iwagakure, they could be more focused on strength and endurance. And the relationships with other characters from different villages would also change the story dynamics.
