Kabuto is an interesting choice. He's a character full of mystery and his ability to transform and use various jutsus could be really cool in a fairy tale setting. He could be like a shape - shifting wizard in a fairy tale who is always plotting something devious.
Hidan is also a great option. His immortality and his brutal nature could be used to create a really menacing villain in a fairy tale. He could be like a cursed being in a fairy tale that can't be killed easily. His unique Jashinist beliefs could be turned into some sort of dark magic in the fairy tale fanfic, making him a truly terrifying antagonist.
Madara Uchiha. He has a grand and complex backstory in Naruto. In a fairy tale fanfiction, he could be the ancient evil that has been sealed away for ages but is now awakening. His powerful Sharingan and his ambition to reshape the world could be the driving force of the story. He could be like the dark lord in a fairy tale, with his own minions and a great plan to take over the fairy tale realm.
Fairy Tale for Villains was a recommended novel. This novel was about a female protagonist who was reincarnated as a servant of the Duke's Palace. She was originally the Viper Queen who caused the Empire to fall into chaos. In the story, she was imprisoned in the Dark Clock Tower with the three siblings of the Duke's family. They had to find a way to escape. The novel unfolded in a fantastical way, full of suspense and thrilling plots. If you like the story of villains, this novel would be a good choice.
Well, one big spoiler is that the main villain has a hidden soft side that comes out in a crucial moment.
Another one is Goro. He's a petty thief in Naruto fanfiction who has a special skill of being able to blend into the shadows. He steals from local merchants in Konoha. Goro may not seem like a big threat at first, but his actions can sometimes lead to bigger problems, like when he steals important items that are needed for a mission.
A theme of subverting expectations is also prevalent. In these novels, the typical fairy - tale tropes are turned on their heads. For example, the hero might not be as noble as first thought, and the villain might have valid reasons for their actions. This makes the reader question their assumptions about good and bad. Also, the theme of power and how it corrupts or can be used for good is often explored. Villains often seek power, and the novels show the consequences of their pursuit, whether it leads to their downfall or a change in their character.
In a Goku fairy tale fanfiction, you could have Goku as a Jack and the Beanstalk type character. He climbs a huge beanstalk to a land in the sky where he has to face off against powerful giants. But instead of using just a sword like Jack, he uses his ki blasts and martial arts skills to defeat them.
One interesting example could be a crossover between 'Cinderella' and 'Beauty and the Beast'. Imagine Cinderella finding herself in the Beast's castle instead of the prince's ball. Another example might be a crossover of 'Snow White' and 'Alice in Wonderland', where Snow White falls down the rabbit hole. There could also be a crossover between 'The Little Mermaid' and 'Sleeping Beauty', perhaps with the mermaid using her voice to break the sleeping curse in a unique way.
The unique aspect is the fresh perspective. Seeing villains in a fairy tale setting is different and keeps you hooked.
Well, you could set it in a magical reform school in a far - off land. The students could be from different fairy tales. Maybe Cinderella's stepsisters are there to learn about humility. And the curriculum could include things like spell - casting for good, and lessons on how to be a better person in a fairy - tale world. You could also have a mystery element, like someone is causing trouble in the school and the students have to figure out who it is.
There's also 'Vicious' by V. E. Schwab. It tells the story of two former friends who become enemies, with elements that can be seen as a modern - day fairy - tale - like exploration of villainy and heroism. It has complex characters and an engaging plot that dives deep into the nature of good and bad.
Well, a Naruto villain in the style of Fairy Tail could be really interesting. For example, Orochimaru could have some Fairy Tail - like magic abilities added to his jutsu. Maybe he could use some sort of dark magic similar to Zeref's in Fairy Tail. In this fanfiction, his motives could also be more complex like Fairy Tail villains, not just about power and immortality but also about some greater, more convoluted plan for the ninja world.
