Dan would probably be shocked at first. He has a complex relationship with both Lucifer and Chloe. But he would also be concerned for Chloe's well - being and the future of the baby. He might offer his help in more practical ways, like making sure Chloe is safe during her detective work. Ella would be super excited. She's always positive and would probably start knitting baby clothes right away and be full of ideas for baby names.
Their friends would probably be really happy. Amenadiel might be a bit surprised at first but then very supportive, seeing how much Lucifer has changed because of Chloe. Dan would be a bit more hesitant, but eventually come around as he sees how happy they are. Maze might be a bit jealous at first, but then she would also be happy for them as she cares about Lucifer.
Dumbledore would be very cautious. He would see Harry's reincarnation as a great risk but also an opportunity. He might try to guide Harry, but also keep a close eye on him to prevent any disasters. The Malfoys would likely see this as a chance to bring down Harry and his friends. They would spread rumors and try to turn the wizarding world against him. Harry's other friends from Gryffindor would be a mix of shocked, scared, and some would be brave enough to stand by him, believing that Harry is still the same person deep down.
Power is a major theme. Two Lucifers would bring a lot of power into one story, and it can be about who has more power or how they use their power together.
In the world of 'lucifer meets lucifer fanfiction', a common plot could involve a clash of egos. When two such powerful and complex characters meet, there's bound to be conflict. Some stories may also explore a romantic or at least a deeply emotional connection between them, as they are essentially the same being in different forms, and this connection can be both fascinating and disturbing at the same time.
Lucifer and Satan were not the same person. Although Lucifer was called the Morning Star, it did not explicitly indicate that he was Satan. Satan was the name of the ancient snake, and Lucifer was an independent existence. Therefore, Lucifer Morgenstern was not Satan.
I'm not entirely sure specifically what 'lucifer fiction' refers to. It could potentially be a genre of fictional works that somehow involve the concept of Lucifer, perhaps in a religious, mythological, or even a more creative and fictionalized context.
