One common theme is redemption. Loki often has to face his past actions and find a way to make amends while in the prison setting. Another theme is mystery. There are usually unsolved cases or strange happenings within the prison that Loki and the OC are trying to figure out.
There's a fanfic titled 'The Prisoner and the Detective Loki'. In this one, the OC is a prisoner who has some unique abilities. Loki, as the detective, is intrigued by this prisoner and starts to dig deeper. It has a really interesting dynamic between Loki's godly nature and the prisoner's down - to - earth but mysterious personality. The story builds up the suspense gradually and keeps you hooked till the end.
Imagine a Loki OC who is a half - Asgardian, half - Vanir orphan. This OC has been living on the fringes of society, but Loki discovers their existence and decides to use them for his own schemes at first. However, the OC's pure heart and kind nature start to change Loki's perspective, and they end up on an adventure together to uncover a long - lost secret about their shared heritage.
Another theme is redemption. Sometimes Loki is in a state where he needs to redeem himself and the OC becomes a part of that journey. They help him see things in a new light and grow as a character. It makes for a very engaging read.
First, develop your OC well. Give the character a distinct personality, appearance, and backstory. For example, if your OC is a shy mage, explain how they got their powers and what their goals are. Then, when it comes to Loki, stay true to his character traits. He's cunning and unpredictable. Incorporate these traits into the interactions between Loki and the OC. Also, create a good plot. It could be something as simple as them solving a mystery together.
I can't really say for sure as it's a rather specific and perhaps not so common type of fanfic. But it might involve themes of power dynamics, given Loki's character often has an air of power and mystery. The relationship between Loki and the original character (oc) could be explored in terms of dominance and submission.
Well, it could be a story where Loki, with his mischievous nature, meets an OC (original character). Maybe the plot involves Loki playing tricks on the OC at first. But as the story progresses, they start to understand each other better. They could go on adventures together, facing various challenges in the magical world. And along the way, their relationship deepens into a unique friendship or something more.
There's also 'The Forced Marriage of Loki and the OC'. It starts with a very tense situation where both Loki and the OC are against the marriage. However, as the story progresses, they start to understand each other's motives and past traumas. The slow - burn aspect of their relationship development is really well - written.
Firstly, research Loki's character thoroughly. Know his motives, his backstory, and his personality traits. Then, create an OC that complements or contrasts with him in an interesting way. For instance, if Loki is known for his trickery, your OC could be brutally honest. In terms of writing style, use vivid descriptions. Instead of just saying 'Loki was angry', describe how his eyes flashed with a cold fury and his muscles tensed. Also, don't be afraid to take risks with the story. Maybe kill off a major character early on or have Loki make a completely unexpected decision that changes the course of the story. This will make your Loki OC fanfic stand out from the rest.
One great Loki x OC fanfic is 'The Enigmatic Bond'. It tells a story of an original character who stumbles into Loki's world and they form an unexpected alliance. The character development in this fic is really well - done.
