How about 'Lucifer Morningstar and His Encounter with the Male OC: A Fanfiction'? This title gives a basic idea of what the fanfiction might be about, that is, an encounter between Lucifer and the male original character.
The theme of identity is often seen. The male oc may be struggling with his own identity, and his encounters with Lucifer force him to reevaluate who he is. There is also the theme of temptation. Lucifer is known for his ability to tempt, and this can play out in different ways in the fanfiction. For example, he might tempt the male oc to use his powers in a certain way or make certain choices that are not entirely ethical.
Well, you could have a plot where the OC is a singer in a club that Lucifer frequents. He's drawn to her voice and her free spirit. As they get to know each other, the OC discovers Lucifer's devilish side but isn't afraid. This could lead to a relationship where they both learn from each other. Also, the OC could be a journalist trying to expose Lucifer's secrets, but instead falls in love with him during the process.
The OC would first need to understand Lucifer's powers. They might have to learn how to control the demonic energy that comes with being Lucifer. It could be a struggle at first, like learning to walk again. For example, Lucifer has the power of manipulation and the OC would need to figure out how to use it without causing chaos right away.
The male OC's reaction to Lucifer's powers and devilish nature is an important element. Will he be afraid, intrigued, or try to use it to his advantage? Additionally, the fanfiction could explore how Lucifer's presence affects the male OC's life. Does it bring chaos or order? Another aspect is the inclusion of other characters from the 'Lucifer' universe. How do they interact with the male OC? Their reactions can add depth to the story. For instance, if Mazikeen is involved, her no - nonsense attitude towards the male OC can create interesting scenarios.
One great 'lucifer x male oc fanfiction' is 'Lucifer's New Companion'. It has an interesting plot where the male oc enters Lucifer's world and they go through various adventures together. The relationship development between them is really well - written.
Focus on unique character traits for your OC. Give them a distinct personality, like being extremely shy but also having a hidden wild side. Also, create a fresh take on the relationship between Lucifer and the OC. Instead of the typical love - hate, make it more of a slow - burn friendship that gradually turns into love.
Another theme is the exploration of good and evil. Since Lucifer is associated with evil in many ways, the oc's presence can either sway him towards good or they both end up in a moral gray area. It makes for really thought - provoking stories.
Lucifer in this fanfiction could be depicted as a complex character. He's likely to be extremely powerful, with a commanding presence. His intelligence would be sharp, always strategizing and thinking several steps ahead.
In the 3x11 fanfic of Chloe and Lucifer, their relationship might be explored in unique ways. Maybe it shows a deeper emotional connection that wasn't fully shown in the original series at that point. It could also introduce new plotlines centered around their characters, like how they deal with a particular crisis together.
