Some ideas for Law and Order OC fanfiction include having an OC as a medical examiner with a hidden past that slowly surfaces during the course of the investigations. This could add an extra layer of mystery to the cases. Also, an OC could be a hacker who uses their skills to help the police, but also has to deal with the legal and ethical implications of their actions. Another option is an OC who is a witness protection officer and the challenges they face in protecting the witnesses while also trying to ensure justice is served in the cases related to those witnesses.
One idea could be exploring an unshown backstory of an OC. For example, a character who has a hidden past related to a major crime in the SVU universe. Maybe they were a witness as a child but were too traumatized to come forward until now, and their presence in the SVU team stirs up old secrets.
Well, you could have a fanfiction where Sasuke, after his redemption arc, teams up with the law enforcers in Konoha. They could work together to track down rogue ninjas who are stealing powerful jutsu scrolls and selling them on the black market. This would involve a lot of action scenes as well as investigations into the underground network of the shinobi world. Also, consider a story where Hinata uses her Byakugan in the context of Law and Order. She could be a key witness in a case where someone is trying to steal secrets from the Hyuga clan, and she has to use her skills to help the authorities find the culprit.
One idea could be creating an OC who is a time - traveling mage from a future where the Grail Wars have had catastrophic consequences. This OC could be on a mission to change the past to prevent the disasters. Another idea is an OC that is a hybrid of a Servant and a human, with unique abilities and a complex backstory that ties into the existing lore of Fate Grand Order. Maybe an OC who was experimented on by the mages in Chaldea and gained strange powers as a result.
One idea could be that the OC is a healer who joins Law's crew. They start off butting heads because Law is so used to being in control, but gradually he comes to rely on the OC's unique healing abilities and they develop a deep bond.
One plot idea could be the Oc and Hermione having to navigate the complex rules of the marriage law. Maybe they initially resist but gradually find common ground and unexpected feelings for each other. For example, they could be paired together by the law and at first be at odds, but as they face challenges in the wizarding world together, they start to rely on and care for one another.
Another idea is to do a crossover within the 'Law and Order' franchise itself. For example, have characters from the original 'Law and Order' work with the SVU team on a high - profile case that involves both criminal acts and special victims. This could lead to some interesting clashes in investigative styles and legal strategies.
One idea could be a fanfic that focuses on the backstory of one of the main detectives. For example, exploring how they got into the field of criminal investigation in the first place. Maybe they had a personal experience with a crime when they were younger that led them to pursue this career.
One idea could be a crossover where the magical world of Harry Potter has to deal with crimes similar to those in Law and Order SVU. For example, there could be a case of a dark magic - related assault in the wizarding world, and the characters from both universes team up to solve it. Maybe Hermione uses her knowledge of laws and spells to help the SVU detectives understand the magical aspects.
One great Law and Order SVU OC fanfiction is 'A New Detective in SVU'. It focuses on an original character who brings a fresh perspective to the squad. The character development is really well - done, and it shows how they interact with the existing team members like Benson and Stabler.
One idea could be to create a story where the detectives are on the trail of a serial killer who leaves mysterious clues at each crime scene that are related to ancient mythology. They have to race against time to decipher the clues before the next victim.
