Maybe a fanfiction where a human race car driver gets telepathically linked to his car during a race. They start to communicate and the car gives the driver advice on how to overtake opponents and win the race in the most unexpected ways.
One idea could be a story where a mechanic has a special bond with a sentient car. The car has unique abilities and they go on adventures together, like solving mysteries in a post - apocalyptic world where cars are the key to finding resources.
One idea could be that cars have human forms and they compete in a global racing championship that's not just about speed but also about strategy and teamwork. The main character, a race car in human form, has to overcome his fear of a particular track.
Perhaps in a post - apocalyptic setting, cars are the only means of transportation left and they form alliances with humans. For example, a group of survivors team up with a fleet of modified cars to fight against a common enemy, like a gang of raiders. The cars could have unique personalities, with some being brave, some cautious, etc.
One idea could be a story where a classic car comes to life and has adventures around the city. It could interact with people, help solve mysteries, and make friends along the way.
One idea could be exploring the backstories of the new characters introduced in Cars 3. For example, you could write about their early racing days, their dreams, and how they got to where they are in the movie. Another idea is to create an alternate ending. Maybe Lightning McQueen doesn't win the big race, and how that would change his relationships and his future in the racing world. You could also write a fanfiction about a friendship between a minor character and a main character that wasn't fully explored in the movie.
One idea could be a crossover between a classic muscle car like a Mustang and a high - tech futuristic vehicle from a sci - fi movie. The story could revolve around a race where the two very different cars compete, with the Mustang having its raw power and the futuristic car having advanced gadgets. Another idea is a crossover between a famous racing car from a video game and a real - world luxury car. They could go on a road trip together, with the racing car's speed and the luxury car's comfort creating an interesting dynamic.
Perhaps a human turns into a car in the fanfiction. This human - turned - car could then participate in the high - stakes races in the Cars universe. They would have to learn how to handle their new form, like dealing with different terrains and using their newfound speed and agility to compete against the other cars. It would be a journey of self - discovery as they adapt to their new life as a vehicle.
Well, you could write a fan fiction where cars from different eras compete in a time - traveling race. For example, a 1960s muscle car against a modern electric supercar. Or perhaps a story about a car that has a sentient AI and it tries to understand human emotions through its interactions with its owner.
Maybe a story where a human engineer creates a highly intelligent robot. The robot becomes the human's closest friend and together they solve mysteries or go on adventures. The robot could have unique abilities that help them in their quests.
One interesting idea could be exploring the human version of Kyubey's complex moral compass. Since in the original, Kyubey's actions are often morally ambiguous. In a human Kyubey fanfiction, we might see how a human with similar characteristics struggles with ethical decisions. For example, a human Kyubey might have to decide whether to sacrifice a few for the greater good, just like the original character does when making magical girl contracts.
One idea could be exploring the life of a human who gains Saiyan-like powers through some scientific experiment gone wrong. They then have to learn to control these new powers while hiding their secret from the world.
