It could be some Slytherin students who are jealous of Luna's unique personality and her friendship with Harry.
Perhaps some of the older students who pick on the younger ones. They might see Luna as an easy target because she's often in her own little world. But they don't realize that Harry won't stand for it. Harry has a strong sense of justice and will protect his friends no matter what.
Maybe the story shows Harry coming across Luna being bullied in a secluded part of Hogwarts. He steps in bravely, using his reputation as the 'Boy Who Lived' to intimidate the bullies into leaving Luna alone. He might also comfort Luna afterwards and form a stronger bond with her.
Once upon a time, Hinata was being bullied near the training grounds. The bullies were taunting her about her shy nature. Just as they were about to get physical, Naruto showed up. He remembered all the times Hinata had been kind to him. 'You guys think it's cool to pick on someone smaller?' Naruto asked. The bullies tried to act tough but Naruto's presence was too much for them. He then turned to Hinata, 'Don't let them get to you. You're strong, Hinata.' And from that day on, Hinata felt a little braver knowing Naruto had her back.
In many Naruto fanfictions, Naruto might save Sakura from bullies by using his ninja skills. He could use his shadow clone jutsu to surround the bullies and intimidate them. Maybe he'd also give them a stern talk about kindness, as Naruto has a big heart.
The bullies in 'A Christmas Story' are Scut Farkus and Grover Dill. Scut is sort of the leader. He's the one Ralphie is most afraid of. He has a face that just looks like a bully's, with a mean sneer. Grover is smaller but just as nasty. They like to pick on the younger kids in the neighborhood, making school and the streets a bit of a nightmare for Ralphie and his pals.
In some Christmas stories, the Grinch could be considered a sort of bully at first. He tries to steal Christmas from the Whos in Whoville. But in the end, he has a change of heart.
In 'A Christmas Story', the main bully is Scut Farkus. He's a mean - looking kid with yellow eyes, according to the narrator. He and his sidekick Grover Dill often pick on the main character Ralphie and his friends. They create a lot of trouble during the Christmas season in the story.
The plot could start with Hinata being alone in a secluded part of the village and the bullies spotting her. They start to tease her about her family or her lack of confidence. Naruto, who has a strong sense of justice, comes across the scene. He uses his skills and his reputation as a hero to scare the bullies away. After that, Hinata and Naruto have a moment where Hinata thanks Naruto, and Naruto encourages her to be more assertive.
The fanfiction 'naruto saves ino from bullies' might start with a scene where Ino is alone and the bullies surround her. Naruto, being the hero, senses the trouble. He dashes towards the scene. He might start by taunting the bullies to draw their attention away from Ino. Then, he could use his speed and agility, which he has developed through his training with Kakashi and others. Once he has the upper hand, he'd make sure the bullies know not to mess with Ino again. After that, he and Ino would probably have a moment of relief and gratitude, strengthening their friendship in the process.
It was a normal day at the ninja school until Sakura found herself surrounded by bullies near the training grounds. They were making fun of her skills and her friendship with Naruto. As the situation was getting worse, Naruto, who had been practicing his stealth skills, quietly approached. He suddenly jumped in between Sakura and the bullies. 'You think you're so tough? Well, you're not!' Naruto said defiantly. The bullies laughed, but Naruto quickly used a simple but effective ninja trick to make them trip and fall. They got up, embarrassed and angry, but seeing Naruto's determination, they decided to leave, and Sakura hugged Naruto tightly, thanking him for saving her.
It depends on how one views it. If it's just for the sake of exploring a different dynamic in a fictional, non - canon way, it could be seen as an interesting experiment. However, if it's portrayed in a way that is mean - spirited and completely out of character for Hermione, then it's not really acceptable. Fanfics should still uphold some basic values of the original work, and in the Potter world, their friendship is a key element.
