One great 'badass gohan fanfic' is 'Gohan's Ascent'. It shows Gohan training in secret and emerging as a super powerful force. Another could be 'Badass Gohan: The New Threat' where he faces an unknown and extremely dangerous enemy all by himself. And 'Gohan's Power Unleashed' is also a good one which focuses on Gohan finally embracing his full potential without any inhibitions.
First, know Gohan's character well. Think about his strengths like his Saiyan power and his intelligence. Then, create a cool and challenging situation for him, like a new super - villain he has to face. For example, you could make the villain have a unique power that forces Gohan to think outside the box. Also, don't be afraid to give Gohan some new moves or abilities. Just make sure they fit his character.
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 some Dragon Ball Z fanfiction where Gohan is neglected, it might explore how he copes with the lack of attention. Maybe he turns to self - training more intensely. He could also form unexpected friendships with other characters who notice his isolation.
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.
You can focus on their emotional bond. For example, show how Goku's pride in Gohan's growth and achievements affects their relationship. It could be about Gohan seeking Goku's approval and Goku being there to give it wholeheartedly.
One common scenario is when new and powerful enemies emerge. Goku will immediately position himself between Gohan and the threat. He'll use his body as a shield if necessary. Another scenario is when Gohan is training and pushes himself too hard. Goku steps in to make sure he doesn't overexert and get injured. In some fanfictions, when Gohan is exploring new places, Goku follows closely behind to protect him from any unknown dangers.
