Well, you can begin by brainstorming some secrets for your OC. What could they be hiding that would make their story interesting? Maybe they have a connection to a criminal organization without the SVU team knowing. Then, you need to think about the setting. Are you going to set your fanfiction in the present day SVU world or in a different time period? After that, start writing short scenes that involve your OC. It doesn't have to be in order at first. Just get your ideas down on paper (or on the screen). As you write more, you can start to piece these scenes together to form a coherent fanfiction story.
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.
One idea could be that OC has been secretly dating a woman who works in the same precinct but in a different department. She could be a forensic scientist. They meet in the coffee room one day, accidentally spill coffee on each other, and that's how it starts. They keep their relationship under wraps because they don't want office gossip to interfere with their jobs.
One common theme is the development of a romantic relationship between Carisi and the original character. Writers often explore how their different personalities interact in a romantic context.
One common theme is the struggle for acceptance. The OC detective often has to prove themselves to the established SVU team. They need to show that they are just as capable as the regular characters. Another theme is dealing with personal demons. The OC might have some past issues that come up while handling cases in SVU.
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.
Many 'Law and Order SVU Male OC Fanfiction' stories also explore relationships. This could be the male OC's relationship with the existing SVU characters. It might be a mentorship - like relationship with Benson or a competitive one with Stabler. And of course, there are often romantic sub - themes as well, where the male OC might develop feelings for another character in the show.
First, you need to choose which shows or elements you want to cross over. Decide on the main characters from SVU that you want to feature and how they will interact with the new elements. For example, if you're crossing with another crime show, figure out which detective from that show will be the main counterpart for the SVU characters.
One great story could be 'Olivia's New Beginning' where an OC enters her life and they work together to solve a complex case. The OC brings a fresh perspective that challenges Olivia's traditional methods, making for an interesting dynamic.
Another way is through external pressures. Say, the SVU team starts to suspect that OC is hiding something. They start to investigate, and as they get closer to the truth, OC and his girlfriend have to be more careful. This could lead to some really intense moments where they almost get caught, and they have to think on their feet to keep their relationship a secret.
Another one to check out is 'Carisi and the Mysterious OC'. This fanfiction takes an exciting approach as it involves a mysterious original character who has a connection to one of the SVU's ongoing cases. It keeps you on the edge of your seat with its plot twists.
