Well, they can get a new perspective. Naruto fanfic often has complex storylines and unique character developments. MLP fans might be used to the colorful and friendship - focused world of My Little Pony. Reading Naruto fanfic can expose them to a more action - packed, ninja - themed world with different values like perseverance and loyalty in a different context. It can also inspire new ideas for their own fan creations, whether it's in writing, drawing or role - playing.
One thing is the expansion of their fictional universe knowledge. Naruto has a vast and detailed world with different clans, jutsus (techniques), and a complex political system. MLP fans can learn about these new elements. Also, they can compare the character relationships in Naruto fanfic to those in MLP. For example, the bonds between Naruto and his friends can be seen in a different light compared to the friendships in MLP. It might give them a deeper understanding of how different fictional worlds build relationships among their characters.
They might gain new writing or storytelling techniques. Naruto fanfic writers often use different narrative styles to describe battles, character growth, and plot twists. MLP fans who are into writing can pick up on these techniques. For instance, the way Naruto fanfic writers build tension during a fight scene can be very different from how it's done in MLP - related stories. Reading Naruto fanfic can also introduce MLP fans to different cultural elements as Naruto is based on Japanese culture, which can be a great source of inspiration for their own creative works.
