One cool Naruto fanfiction could be about a new character with a rare bloodline introduced during a filler arc. This character might have the power to control shadows in a unique way, different from Shikamaru's. The story could revolve around their journey to master this power and how they interact with the main Naruto characters during the filler events.
Filler words also play a role in the development of the narrative voice. An omniscient narrator might use different filler words compared to a first - person narrator. The choice of filler words can also change over the course of the novel as the character grows or the situation changes. For instance, a character who becomes more confident might use fewer filler words as the story progresses.
In novels, filler words can also be used for character differentiation. A nervous character might use more 'um's and 'ah's compared to a confident one. They can be a subtle tool for characterization. Moreover, in some cases, filler words can be used to create a regional or social dialect. For example, certain words might be more common in a rural setting's dialogue, which can help to paint a more vivid picture of the world in the novel.
Sure. There's a fanfic where in a filler arc, a character has a bloodline that can create illusions within illusions. It's really cool as it adds a new layer of complexity to the battles in the Naruto world. The character uses this ability during the filler arc to outwit powerful enemies.
