What Could Be the Reason for Naruto to Transform into a Dragon in Fanfic?

Well, in some fanfictions, it could be due to a special encounter. Maybe he meets a powerful dragon spirit during one of his adventures. This spirit, seeing Naruto's potential and kind heart, bestows upon him the power to transform into a dragon.

One possible reason could be a difference in their values. Naruto, from the Naruto series, values loyalty and hard - work above all. Barbara, perhaps from a different fictional universe, might value something else like purity or grace. Their different upbringings and the worlds they come from could also contribute. For example, Naruto grew up in a world full of ninja battles and had to fight for his place. Barbara might come from a more peaceful or magically - inclined world. When their paths cross, these differences in values and backgrounds could lead to an argument.

Maybe it's a misunderstanding. Barbara could be mistaken for an enemy by Naruto. She might be in his world by accident and her actions seem suspicious to him. For example, if she's looking for something that Naruto thinks is important to protect, he might attack first and then the fight breaks out.

In a fanfic, it could be for comedic purposes as well. The idea of Sasuke trying to act like Sakura while tricking Naruto can lead to some really funny situations. Maybe Sasuke is forced into this by some strange situation or magic. And he has to keep up the act of being Sakura, which includes mimicking her mannerisms and speech patterns, all while trying to fool Naruto. This could create a lot of humorous misunderstandings and interactions within the story.

I recommend "10,001 Ways to Live as a Protagonist" to you! The protagonist, Nameless, carried thousands of protagonist souls from different worlds in his body. In the world of magic and fantasy, he set foot on the first stop to find the meaning of life, until the creator known as God destroyed everything. Nameless carried the name of the protagonist and resolutely embarked on the path of fighting against God. The nature of this novel is fantasy-mystery fantasy, so it's very enjoyable to read! I hope you like my recommendation, Mwah ~😗

One possible reason could be a new threat to Konoha that only Naruto has the power to face. For example, a powerful enemy has emerged and the village elders believe Naruto's strength is essential for the village's defense.

If it's not about adult content (assuming 'lemon' is just a strange part of the title), it could be about Naruto becoming a dragon champion. Maybe he discovers some ancient dragon - related power or technique in the Naruto universe and has to master it to face a new threat. He could go on a journey to find dragon - like creatures who will help him in his quest.

Perhaps the civilians have been influenced by some anti - Naruto propaganda. They might not understand the true nature of Naruto and the fact that he has no intention of harming them. Also, they could be in a state of panic after some events that they wrongly blame on Naruto. For instance, if there was some minor destruction in the village that was actually caused by other factors but they assume it was Naruto's doing because of his connection to the Nine - Tailed Fox. This could lead them to try and harm him until Kakashi steps in to rescue him.

One possible reason could be that he has become jaded after facing so many hardships in his life. He might have seen too much pain and loss, which has made him numb and less caring in the fictional scenarios of fanfiction.

It could be a result of a deal with a powerful and mysterious being. Naruto, in his quest to protect the village, makes a deal where he sacrifices part of his own essence. In return, he is given the power of the Hoshigaki, which slowly transforms him. He then has to figure out how to use this new power without losing his true self.
