A really cool plot could be that the last royal vampire discovers a prophecy about their role in saving the vampire race from a new, unknown threat. This threat could be something like a powerful dark magic that is slowly corrupting all vampires. The vampire then has to search for ancient artifacts or knowledge to combat this threat, all while dealing with internal vampire politics.
One idea could be exploring the origin of the last royal vampire's powers. Maybe there's a long - forgotten spell or a unique bloodline trait that gives them special abilities. Another could be a love story between the vampire and a human who is immune to their charm, which creates a lot of interesting conflicts.
There could be the last royal vampire themselves, of course. Then perhaps a loyal servant or advisor who has been with the vampire's family for generations. A hunter who initially wants to kill the vampire but then realizes they may be the key to something bigger is also a great character.
One interesting plot could be the discovery of an ancient prophecy that states a person with a specific Zanpakuto bloodline will be the key to saving the Naruto world from an impending doom. This person is initially unaware of their bloodline and must go on a journey of self - discovery. As they do, they learn about the power of their Zanpakuto and how it relates to their bloodline. They face numerous challenges, including battles with other powerful ninjas who want to use the prophecy for their own gain.
One idea could be a character with a devil bloodline being initially shunned in the Hidden Leaf Village but then proving their worth in a major battle. For example, they could use their unique devil - like abilities, such as enhanced speed and strength, to turn the tide against a powerful enemy.
Perhaps in the fanfic, the hypnosis bloodline allows the user to enter people's minds and change their memories. The story could be about a character who uses this ability to rewrite the past of a village that has been corrupted by an evil force. However, they soon realize that changing memories has unforeseen consequences and they have to find a way to fix the mess they've created.
One idea could be that the last dragon is discovered by a young adventurer. They form an unlikely bond and together they set out to find a way to save the dragon's kind from extinction. Maybe there are ancient prophecies or hidden magic involved.
One idea could be exploring an alternate timeline where Aang fails to defeat the Fire Lord. Maybe in this timeline, the Fire Nation completely takes over the world, and the remaining benders have to go into hiding and plan a long - term resistance. Another plot could be focusing on a new airbender discovered long after Aang's time, and their journey to master airbending without the guidance Aang had.
A cool plot for 'the last kingdom fanfic' might be to have a character be transported back in time to a crucial moment in the kingdom's history. They would have the knowledge of what's to come but struggle to convince others to believe them. This could lead to all sorts of interesting twists. Or you could write about a character who is secretly training a group of women to be warriors in a society that doesn't really accept that. It would be about breaking gender norms and the challenges they face in a war - torn world.
Well, you could have a story where a new type of Pokemon is discovered that has vampire - like characteristics, like draining the energy of other Pokemon instead of blood. The main character, a young trainer, has to figure out how to deal with this new threat. Or perhaps there's a vampire Pokemon that was once a normal Pokemon but was cursed. It then tries to find a way to break the curse while befriending a group of trainers.
Perhaps a story where the characters from Vampire Academy get transported to a different time or dimension. They have to adapt to the new environment while also trying to find a way back home, and in the process, they discover new things about their own powers and relationships.
Well, a great plot for a Royal Ward Harry Potter fanfic could involve Harry being sent to the Royal Ward for protection.

He then has to use his skills and the help of new friends he makes in the Ward, like a healer - in - training who has a special gift for seeing the future through potions. They work together to stop the dark wizards and in the process, Harry learns more about his own family's connection to the Royal Ward.
