One idea could be an OC who is a detective with a unique Sibyl System reading. Maybe their Crime Coefficient fluctuates in strange ways due to a past trauma that they have to keep hidden. Another could be an OC who is part of a rebel group against the Sibyl System but has to infiltrate the enforcement unit.
Well, you could write a fanfiction about Mob's family. For example, how his older brother's life was affected by having a psychic younger brother. Maybe there were times when he was jealous or proud in ways that haven't been explored much in the original. Or a story where Mob uses his powers to help people in a more global sense, like solving international disputes with his psychic abilities, which would be a very different take on the usual small - scale problems he faces in the anime.
You need to think about their place in the Psycho Pass world. Are they an enforcer, an inspector, or something else entirely? If they're an enforcer, what led them to that position? Maybe they had a high Crime Coefficient once but managed to get it under control. Also, consider their beliefs. Do they blindly follow the Sibyl System or are they more skeptical? All these elements combined will help you create a believable OC.
A crossover with Jujutsu Kaisen would also be cool. Mob and Yuji could team up against curses. Since Mob has such strong psychic powers and Yuji has his physical strength and Sukuna's power, they could combine their abilities in unique ways. For example, Mob could use his psychic powers to hold a curse in place while Yuji delivers a powerful physical blow.
Definitely. The plot in Psycho Pass is engaging. It has elements of crime - solving, but also a deeper exploration of society and human nature. It constantly challenges the viewer's ideas about right and wrong, which is what makes the plot so interesting.
Well, you could have an OC that is a skilled hacker who gets involved with the Phantom Thieves by accident. They might have a Persona that represents a famous code - breaker from history. Also, an OC who is a foreign exchange student from a country with a very different cultural background could bring in new elements to the fanfiction. Their Persona could be influenced by their home country's folklore. Maybe an OC who is a prodigy artist and uses their art skills to create powerful items in the Metaverse, with a Persona related to a great artist from the past.
You could have an OC that is a young witch who idolizes Bayonetta. She tries to copy Bayonetta's style and fighting techniques but often fails in a comical way at first. As the story progresses, she discovers her own unique way of being a witch. Or an OC who is a cursed object collector. This OC comes across Bayonetta when investigating a powerful cursed object and they end up working together to either destroy or control the object's power.
One idea could be an OC who is a spy sent to infiltrate Doflamingo's organization. This OC could have a hidden past that slowly gets revealed as they gain Doflamingo's trust. Another idea is an OC with a special power that Doflamingo wants to control or use for his own evil plans. For example, the OC might be able to manipulate time in a small area, which could be a great asset in battles or heists.
One idea could be to create an OC who is a new dancer in town. This OC could bring a different style of dancing to Footloose's world, like a fusion of modern and traditional dance. They could face challenges in getting the town to accept this new form of expression.
A great concept for superhero oc fanfiction is a hero who has the power of empathy. They can sense the emotions of others and use that to either calm down villains or boost the morale of their fellow superheroes. Also, you could write about a superhero oc from another dimension who comes to our world with powers that are completely alien to our understanding, like the ability to turn into a living energy form.
One idea could be to create a 2d oc who is a time - traveling detective in a steampunk world. They could solve mysteries that are related to the alteration of historical events.
