In a Naruto fanfic, Itachi's prodigy status could be used to create an alternate storyline. Maybe he was discovered by a secret organization at a young age because of his abilities. This organization could try to recruit him, and Itachi would have to decide whether to join or stay loyal to his clan. The fanfic could explore the moral dilemmas he faced due to his prodigious talent and the different paths that could open up for him as a result.
One great 'Percy being a badass' fanfiction is 'Percy Jackson: The Badass Avenger'. In this story, Percy uses his skills and powers in really cool and unexpected ways. He takes on powerful enemies all by himself and shows his true strength.
One example could be when he single - handedly takes on a horde of monsters in a fanfiction. His water powers create massive tidal waves that sweep away the foes. Another instance is when he uses his wits and sword skills to defeat a powerful, new - created villain in a fan - made adventure.
Perhaps Sakura is amused by Itachi's unique skills or his way of handling things. Meanwhile, Shisui annoys her because he has a different approach to things that she doesn't like. In the fanfiction, it could be that Shisui is too brash compared to Itachi's calmness, and Sakura, being a fan of Itachi, just can't stand Shisui's antics.
In certain fanfiction stories, Hermione is portrayed as a spy in the dark wizard's lair. She has to blend in, gather intelligence, and escape without being detected. She uses her wits to deceive the dark wizards, and when she's finally discovered, she uses her combat magic to fight her way out. This shows her as a really badass character, being able to handle such a dangerous and complex situation all by herself.
In this fanfiction, Hinata could be badass in a way that she challenges the village elders directly about Naruto's banishment. She argues that Naruto has been the savior of the village multiple times and his banishment is unjust. As she does this, she also showcases her new and improved combat skills, which she has been secretly honing, to intimidate those who oppose her and show that she will fight for Naruto's return.
Sasuke could also be confused. He has always had a mix of emotions towards Itachi, including love, hate, and envy. Being kidnapped by him would add another layer of confusion. He might wonder if Itachi has some new plan or if he's finally going to reveal some long - hidden truth. So, he might hold back on his full - fledged resistance and wait to see what Itachi has to say.
Often, in fanfic, Naruto is made stronger than Itachi because the writers want to explore new story arcs. If Naruto is stronger, new and exciting battles and relationships can be created. For instance, Naruto could be the one to protect Sasuke from Itachi in a different way. Also, Naruto's positive and determined nature makes him a popular character to be super - powered in fanfics.
One implication is a shift in Naruto's character development. He might inherit different traits from Itachi. Also, the relationship between Naruto and Sasuke would be completely redefined.
