In fanfiction, Naruto getting Shisui's eye could lead to a whole new plotline. It could potentially be a way to bridge the gap between the Uchiha clan and Naruto. Since Shisui was an important Uchiha, having his eye might give Naruto a connection to the clan's history and secrets. This could play a role in resolving some of the long - standing issues between the Uchiha and the rest of the village. Naruto might also use the eye's powers in unique ways, like combining it with his own Uzumaki chakra, creating new and unexpected jutsu.
Another theme is sacrifice. Given their fates in the original Naruto story, fanfictions often play with the idea of how much they were willing to sacrifice for their village, their clan, and for each other. For example, Shisui's sacrifice and how it affected Itachi.
Another one is 'Itachi and Shisui: The Untold Tales'. This story weaves in some unique scenarios that might not have been explored in the original series. It shows their interactions with other characters from a different perspective, highlighting their strong bond.
One possible plot implication is that it could create a rift between Naruto and some of the shinobi in the village. Since the Sharingan is an Uchiha - specific power, some might be suspicious of Naruto having it. Another is that it could lead to Naruto being targeted by those who want the Sharingan for themselves.
One popular one might be 'The Bonds We Share'. It delves deep into the complex relationships between the three characters. The reader is often portrayed as someone who bridges the gap between Shisui and Itachi, and the story unfolds with a lot of emotional depth and character development.
Sakura's amusement could actually make Shisui more likely to continue annoying Itachi. Since she finds it funny, Shisui might see it as a sign that his actions are acceptable and entertaining. This could potentially strain the relationship between Shisui and Itachi further if Itachi doesn't like being the target of Shisui's annoyance.
Well, Naruto already has his own powerful abilities like the Nine - Tails' chakra. But with Shisui's Sharingan, his perception skills would be enhanced. He could probably anticipate attacks better and maybe even use some basic Sharingan - related genjutsu. However, it would also be a challenge for him to master as he has no prior experience with the Uchiha's dojutsu.
He'd probably become more perceptive. Shisui's eye might enhance Naruto's ability to read situations and opponents, which would make him a better strategist in combat.
One common theme is loyalty. Given their status as Uchiha, loyalty to the clan and to each other is often explored. For example, in many fanfics, they will go to great lengths to protect one another because of their loyalty.
Another theme is sacrifice. Given their fates in the original story, fanfictions often play around with the idea of how much they are willing to sacrifice for each other and for the greater good. It could be sacrificing their own lives or their own happiness for the other.
