I'm not sure which Naruto anime or manga you're referring to because you didn't provide any specific information. However, in general, the plot and plot arrangement of Naruto's animation and manga were different. If you can provide the specific title of the work or the number of episodes, I can try to help you answer your questions.
In some Naruto fanfictions, Gaia might be possessive of Naruto because he represents a new hope or a different way of doing things. Gaia, being an important entity in the fanfiction universe, might see Naruto as a way to change the status quo. His kind - hearted nature and strong will could be what attracts her, and she's possessive to protect and guide him so that he can fulfill the potential she sees in him. She might also be possessive because she's the only one who truly understands his significance in the grand scheme of the fanfiction world.
In some Naruto fanfictions, Naruto might faint due to overusing his chakra. For example, if he pushes himself too hard in a battle, like when he tries to use a new and extremely powerful jutsu without fully mastering it. His body can't handle the excessive chakra drain, and he faints as a result.
Well, Kyuubi might be possessive of Naruto because they have a unique bond. Kyuubi has been inside Naruto for a long time. They've shared experiences, and Kyuubi may see Naruto as its own in a way. Also, Naruto has sort of tamed Kyuubi to an extent, and this might make Kyuubi feel like Naruto is special to it, so it shows possessiveness.
One possible reason could be that Naruto had a traumatic experience related to thunder when he was young. Maybe he was alone during a thunderstorm and something really scary happened, like seeing a lightning strike too close for comfort. This could have left a lasting mark on his psyche, making him fear thunder in the fanfiction.
In many Naruto fanfictions, Naruto might have developed some new and unique abilities that the Kyuubi has no defense against. This could make the Kyuubi, which is used to being a dominant and feared force, feel vulnerable. For example, if Naruto has the power to nullify the Kyuubi's chakra or to manipulate it in a way that goes against the Kyuubi's will, it would be a cause for fear.
Another reason could be to appeal to a wider range of readers. Some readers might be interested in seeing a different take on a beloved character. A feminine Naruto can bring in elements of different genres, like a touch of romance or a different kind of friendship story. It can also add a new layer of depth to the existing Naruto story, making it more relatable or interesting for those who might have already read a lot of the traditional Naruto fanfictions.
Some writers create 'Naruto is shuned' fanfics to delve deeper into Naruto's character. When he's shunned, his emotions, growth, and how he overcomes adversity can be explored in a different way compared to the original series. For instance, it can show his resilience and ability to find his own path even when rejected by those he once considered friends or family in the village. Also, it can create interesting relationships with other characters who either side with the village or with Naruto during his time of being shunned.
One reason could be that some fans might be disappointed with certain aspects of the original Naruto series. For example, the development of some characters might not meet their expectations. So, they create fanfiction to express their negative feelings.
