What could be the reasons for Naruto to start speaking in a different language in fanfics?

One interesting fanfic could be 'Naruto's Multilingual Adventures'. In this fanfic, Naruto starts learning different languages during his travels and uses them to form unique bonds with people from various regions. It shows his growth not just as a ninja but also as a global communicator.

Maybe he saw someone he respected smoking a pipe and thought it looked cool, so he decided to try it.

One reason could be that Tsunade showed him a great deal of care and concern that was similar to a mother's love. For example, she might have healed his wounds or protected him in a way that made him feel like she was family. Another possibility is that Naruto was longing for a motherly presence in his life, and Tsunade's actions towards him filled that void. She could have also given him a sense of stability and security that he associated with a mother - son relationship.

In the fanfic, it might be because of a misunderstanding. For example, Sasuke could be wrongly accused of something, and Sakura, believing the false rumors, is so disappointed in him that she refuses to talk. Or perhaps Sasuke accidentally said something really offensive during an argument, which made Sakura so angry that she just cut off communication.

The most obvious difference is the religious element. Christian Naruto fanfics may introduce Christian values, beliefs or practices into the Naruto world. For instance, a character might pray before a battle in a way that doesn't exist in the original Naruto.

Well, a Naruto yaoi fanfic could be 'Love in the Hidden Leaf'. It might tell a story about Naruto falling in love with a male shinobi from the village. Then there's 'Sasuke's Heart's Whisper' which could be about Sasuke having a soft spot for a male in a yaoi - centric plot. 'Naruto's Secret Admirer' is also a possible fanfic, where Naruto has a secret male admirer in the Naruto world.

One possible reason could be for power enhancement. In some fanfic concepts, drinking blood might be associated with gaining special abilities or strength. For example, if there's a dark magic or forbidden jutsu involved that requires the consumption of blood to unlock certain powers.

Another reason might be that he has some internal conflict. For example, he could be doubting the purpose of the training. If he doesn't see a clear goal or if he's starting to question the methods, he might refuse. In some fanfics, he could also be influenced by new friends or ideas that make him question the traditional ninja training regime.

In some fanfictions, Naruto might leave because of a rift within the village. If there are political factions that oppose him or his methods, and he feels that he can no longer operate effectively within the village, he may choose to leave. This could also be due to a misunderstanding or false accusations against him that he can't seem to clear up while remaining in the village.

One reason could be a sense of disillusionment with the village's leadership. Maybe they discover some dark secrets about the elders and decide they can't be part of it anymore. Another reason might be to protect the village in their own way. They could think that by leaving, they draw danger away from their home. Also, they might be seeking a greater power or knowledge that can only be found outside the village.
