A great plot could be where the angel reader is a part of a group that is hunting Lucifer. But as they get closer to him, they start to see a different side of him that challenges all their beliefs. Lucifer, in turn, becomes intrigued by the reader's unwavering sense of justice and tries to make them see his point of view, leading to a complex relationship dynamic.
One plot idea could be that the reader, an angel, is sent on a mission to redeem Lucifer. Along the way, they have many intense philosophical debates about good and evil, which gradually lead to an unexpected bond between them.
First, there should be conflict. Lucifer has his own motives and the angel reader has their duties. So, they might start by being at odds with each other. For example, the reader could try to stop Lucifer from causing chaos, but Lucifer might see it as the reader being naive. Then, as they interact more, they could start to understand each other's perspectives. Maybe the reader realizes that Lucifer has some valid points about the flaws in the celestial order, and Lucifer sees that the reader is not just a mindless follower. This slow shift in their views of each other can build a more realistic relationship.
Maybe the angel reader has the power to heal, and one of the lost boys gets injured. The angel saves his life, which then binds them in an unexpected way. The other lost boys are both grateful and a bit jealous. This leads to a series of events where the angel has to navigate the complex relationships among the lost boys while also hiding their true identity from the outside world.
One idea could be that Harry, with his magical skills, somehow ends up in Lucifer's realm. He tries to find a way back home while Lucifer is intrigued by his magic and wants to learn from him. Another could be that they team up to fight a common enemy that threatens both the wizarding world and Lucifer's domain.
One idea could be that they form an alliance to rule over a certain realm. They combine their powers and knowledge to bring order in a chaotic land. Alastor's cunning and Lucifer's authority could make for a very interesting power dynamic.
One idea could be an angel family dealing with a new threat from a powerful dark entity. The angels have to put aside their internal differences to protect the world. For example, an angel family that has a young and inexperienced angel who discovers a unique power that could be the key to victory but they need to train the young one fast.
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.
One idea could be that Lucifer from 'Lucifer' ends up in the 'Supernatural' universe and teams up with the Winchester brothers to fight a common enemy, like a powerful demon that's causing chaos in both their worlds. Maybe he uses his charm and powers in a unique way to help them out.
One plot idea could be that Lucifer and Sabrina team up to solve a mystery that threatens both their worlds. They start off as reluctant allies but as they work together, they begin to understand and respect each other.
One common theme is the power dynamic. Lucifer being a powerful character, there's often a play on his dominance in these fictions. Another theme is the forbidden love aspect, as Lucifer is a villain in the Supernatural universe. There's also the idea of seduction, where Lucifer uses his charm to draw the reader in.
A plot idea could be that Lucifer wakes up in a human body with no memory of who he is. He starts living a normal life until strange things start happening around him that hint at his true identity. As he slowly regains fragments of his memory, he has to decide whether to embrace his old self or continue his new life.
