One secret idea could be basing a story on a family heirloom. Each heirloom has a history and stories associated with it. For example, a mysterious old locket that was passed down through generations. It could hold a secret message or be a key to a long - forgotten family mystery. This can add an element of mystery and heritage to the story.
One idea could be a secret agent who has to infiltrate a high - tech corporation to stop a rogue AI from taking over the world. The agent could face various challenges like bypassing advanced security systems and dealing with double agents within the company.
First, you need to expand on the central secret idea. For instance, if your secret idea is a hidden treasure map. You start by thinking about where the map was found, who might have hidden the treasure, and why. Then, you create characters. Maybe a young adventurer who discovers the map by accident. Next, add conflict. There could be an evil villain who also wants the treasure. With these elements, you can start weaving them together to form a full - fledged story.
Another possibility is that Percy is recruited by a secret organization that has discovered his demigod powers. They see his potential as a secret agent because of his combat skills, quick thinking, and ability to adapt in dangerous situations. In this fanfiction, he might have to work with other agents who are initially skeptical of his 'weird' powers but soon come to respect and rely on him.
Look at real - world events and adapt them. For example, if there's a new technology emerging, you can create a story where secret agents are involved in either protecting or stealing it. Say, a new form of energy source that could change the balance of power in the world.
Imagine a superhero who is a librarian in his normal life. He has the power of super - intelligence and can read and understand any book instantly. His secret identity allows him to research and study various threats in the safety of the library. One day, a villain starts spreading misinformation through books and libraries. The librarian - superhero uses his power to find the source of the false information, which leads him to an underground lair. He battles the villain using his knowledge of ancient fighting techniques he learned from old martial arts books, all while keeping his identity as a mild - mannered librarian.
You could create a fanfiction where the main character discovers a new, hidden part of Moonacre that was never mentioned in the original story. Maybe it's a magical garden that holds the key to an even greater mystery. This would add a new layer of adventure and intrigue.
Some fanfictions might explore the idea that the secret tattoos are a curse in disguise. They seem cool at first, but as the story unfolds, the characters with the tattoos start to face unexpected problems. It could be that the tattoos attract dark forces or cause internal conflicts within the ninja who has them.
One plot idea could be that Naruto has a secret training regime away from the village. He discovers a hidden cave where he finds ancient scrolls that teach him unique jutsu not known in the village. This new knowledge makes him even more powerful and he has to keep it a secret as he doesn't know if the jutsu are safe or how the village will react.
One idea could be a story where the pets form a secret club to solve mysteries in the neighborhood. For example, they might investigate strange noises coming from an old abandoned house. Another idea is a love story between two different species of pets, like a cat and a dog, who have to overcome their natural differences. And perhaps a story where the pets go on an adventure to a magical land that only they can access through a hidden portal in their owner's backyard.
