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.
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.
Perhaps in a fanfiction, a time - traveling scenario occurs. Vegeta travels back in time and ends up in the Naruto universe. There, he falls in love with a kunoichi and has a child. Generations pass, and Naruto is related to that child's line, thus making him related to Vegeta. It's a wild and wacky idea but could make for an interesting fanfiction.
Well, it would be a really wild concept. Naruto's ninja world and Vegeta's Saiyan heritage are so different. Maybe Naruto would teach Vegeta some ninja skills like stealth and using chakra in unique ways. And Vegeta might introduce Naruto to Saiyan combat techniques. It could be a story full of clashes between their different values and powers, but also of them learning from each other.
In these fics, Sakura often becomes badass through intense training. She realizes that she needs to be stronger to change things in Konoha or to prove herself. For example, she might train under a mysterious master or in isolation, like in 'Sakura's Solitary Training' where she spends months alone in the forest, honing her skills.
A possible plot could be that they are transported to a parallel universe where male Saiyans are able to get pregnant. They meet alternate versions of themselves and their friends, and have to adapt to this new world while dealing with their pregnancy. This could lead to many adventures and self - discovery moments for both of them.
Sakura might be initially shocked and worried. She'd be concerned about how this new entity within Naruto could affect his health and stability. But she'd also be curious to see if this could give them an edge in future battles.
