A fan fiction could revolve around Robot Jones getting a software upgrade that gives him new emotions. He then has to learn how to deal with these emotions in the context of his daily life at school and with his friends.
One possible plot idea could be a new adventure where the main characters from Kingdom Hearts find themselves in a digital world created by the topless robot. Maybe they have to solve puzzles related to the robot's programming to find their way back to their normal world.
Some robot fan fiction focuses on the relationship between a human and a robot. For example, a scientist creates a highly advanced robot and they develop a deep bond over time. The robot helps the scientist in his research and also protects him from danger. This kind of story explores the themes of trust and loyalty between different forms of intelligence.
One example could be a fan fiction where Alex Jones discovers a hidden conspiracy within his own organization. It might involve him having to fight against his former allies to expose the truth.
First, think about the characters you want to include. Besides Robot Jones, you could bring in his classmates or teachers. Then, come up with a simple plot like Robot Jones trying to win a school competition.
Some Osmosis Jones fanfiction ideas might involve relationships. For instance, a story about Osmosis Jones falling in love with another cell in the body. It could be a comical love story where they face challenges like misunderstandings and the chaos of the body's functions. Or, there could be a fanfiction where Osmosis Jones has to mentor a young, inexperienced cell and teach it the ropes of protecting the body. Also, a story about Osmosis Jones getting lost in a maze - like part of the body and having to find his way back while fending off germs would be interesting.
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 backstories of the robots in more detail. For example, what were their initial programming thoughts and feelings before they started interacting with humans? Another could be imagining new types of robots that were not in the original I, Robot story, like robots with the ability to create art or music.
One interesting Indiana Jones fan fiction could be about Indiana Jones going on a quest to find a lost city in the Amazon that was rumored to hold the key to eternal youth. Another might be him teaming up with a female archaeologist to solve a mystery in an ancient Egyptian tomb.
Well, you could write a fan fic where the relationships between the characters are reversed. So if in the original there are certain rivalries, in the fan fic they become allies and vice versa. Also, a story about a character who loses their power but discovers a new way to be strong within the 'unordinary' world would be interesting. Or how about a fan fic that takes place in a parallel dimension within the 'unordinary' universe where the rules of powers are slightly different?
Some interesting ideas for Riverdale fan fiction could be a crossover with another popular teen drama. Imagine the characters of Riverdale meeting the characters from 'Stranger Things'. It would be really cool to see how they interact. You could also write a fan fiction that focuses on the future of Riverdale. What will happen to the town and its residents ten years from now? Will Archie still be in town? How will Veronica's business empire develop?
