Who are the main characters in 'harry is lucifer's vessel fanfiction'?

One interesting idea could be the exploration of Harry's internal struggle as he becomes Lucifer's vessel. He might face a moral dilemma between his own values and the dark influence of Lucifer.

Well, Harry is bound to be a central figure in this fanfiction. And since it's about 'Lucifer reborn' in relation to Harry, it's possible that there could be characters who are either allies or enemies of this new Harry - Lucifer entity. There might also be some original 'Harry Potter' characters like Dumbledore or Voldemort who play important roles in the story, perhaps having to deal with this new and changed Harry.

Obviously, Harry Potter would be one of the main characters. And then there would be Lucifer. Depending on the story, characters like Hermione and Ron might also play important roles as they interact with Lucifer in the wizarding world.

The main character would be the daughter of Lucifer. Depending on the plot, other important characters could include some of the powerful demons who might be trying to control or use her. Also, there might be some human characters who get involved with her story, perhaps a hunter who initially wants to kill her but then realizes she's not all bad. And of course, Lucifer himself might make appearances to influence his daughter's actions.

I don't have enough information to determine the main characters. They could be dragon tamers, adventurers, or people with a special connection to the dragon vessel.

Yes, there are quite a few. You can check out fanfiction websites like Archive of Our Own. There you might find some interesting takes on this concept, with different plotlines and character developments. Some might explore how Harry's world and Castiel's world interact when he becomes the vessel, while others could focus on the emotional and physical changes Harry experiences.

The protagonist is often the central main character. But without having read it thoroughly, I can't give you all the main characters precisely.

Well, obviously Lucifer and Chloe are the main characters. Lucifer, with his devil - like charm and powers, and Chloe, the detective. Their marriage is the central focus, so they are the ones around whom all the stories revolve.

One common theme is the struggle for control. Harry has to deal with Castiel's power and sometimes they might fight for who's in charge. Another theme is the exploration of new abilities. Harry gets access to Castiel's angelic powers and has to learn how to use them.

Since I haven't had the chance to read 'love in a broken vessel book 3 a novel', it's hard to say for sure. However, in a novel about love in a difficult situation like a 'broken vessel', the main characters might be individuals who are struggling with their own insecurities or past traumas. They could be people who are trying to find love or hold on to love in spite of these internal or external 'broken' elements. There might also be a character who acts as a catalyst for change in the love story.
