What would be the most interesting plot twists in a Harry Potter as the son of Lucifer Morningstar fanfiction?

Perhaps Lucifer is actually an ancient dark wizard who was banished long ago and is now trying to return using the chaos of the wizarding war in Harry Potter's time. He could manipulate events from the shadows, and Harry, with the help of Dumbledore's portraits (which have some ethereal knowledge), figures out Lucifer's true identity and purpose, leading to a showdown that combines magic from both universes.

One interesting crossover could be a scenario where Harry Potter is transported to Lucifer's world in Los Angeles. Maybe he needs Lucifer's help to defeat a new kind of dark magic that has some connection to the infernal realm. For example, a dark wizard has made a pact with a minor demon and is causing chaos in both the wizarding world and the human world. Harry, with his knowledge of magic, and Lucifer, with his understanding of the supernatural in his own realm, could team up to solve the problem.

Well, in some fanfictions, Lucifer Morningstar could be curious about the magic in the Harry Potter universe. He might visit Hogwarts in disguise and cause chaos. He could interact with Dumbledore, who would be very cautious of him. There could also be a fanfiction where Harry Potter and his friends have to go to Hell (Lucifer's domain) to retrieve a lost magical artifact and face all kinds of devilish challenges along the way.

A really interesting plot twist could be that Harry's Mikaelson heritage makes him immune to some of Voldemort's dark magic. This would completely change the dynamic of their battles. Another twist could be that the Mikaelson family shows up at Hogwarts to protect Harry, causing chaos among the students and teachers who have no idea about this new, powerful family. Or perhaps Harry discovers that his connection to the Mikaelsons is the key to unlocking a new, more powerful form of magic that was previously unknown in the wizarding world.

One interesting plot twist could be that Harry's wizarding powers are enhanced by Wayne's technology. Imagine Harry using some sort of high - tech broomstick or a magical device upgraded with Wayne Enterprises' tech. It would be a cool blend of magic and technology.

Harry's Patronus charm, which is a manifestation of positive energy, could have an interesting reaction when in the presence of Lucifer. Since Lucifer is associated with the underworld and negative forces in a way, the Patronus might act as a counterbalance or even a repellent to some of the darker aspects of Lucifer's world. At the same time, Lucifer's power to see people's desires could help Harry understand the motives of his enemies better. For example, if they were facing a dark wizard who had some hidden desires that were fueling his actions, Lucifer could reveal those, and Harry could then use that knowledge to find a way to defeat the wizard using his magic.

One exciting plot twist could be that Voldemort discovers Harry's connection to Deathstroke and tries to use it against him. He might try to turn Deathstroke against Harry or use Deathstroke's enemies to attack Harry. Also, what if the Ministry of Magic finds out about Harry's true father? They could see him as a threat and try to expel him from Hogwarts. But then, it turns out that some of the Ministry officials are actually in league with Deathstroke's enemies, and Harry has to fight against both the Ministry and the dark forces. This would add a whole new layer of complexity to the story.

Well, one way could be by exploring the clash of two very different magical worlds. Harry would have to deal with the expectations of the wizarding world from his Potter side and the dark, otherworldly nature of being Lucifer's son. Maybe he'd have new and strange powers that would both terrify and amaze his friends at Hogwarts.

It would be extremely different from the original Harry Potter story. Instead of having the noble and self - sacrificing qualities associated with being the son of James and Lily Potter, he might have darker, more malevolent tendencies. His magic could be more of a corrupted or shadowy form. The Hogwarts environment would likely be a much more dangerous and morally ambiguous place.

One interesting plot twist could be when Caesar turns out to be a long - lost wizard. This completely changes the dynamic as he then has to learn about his magical heritage while also dealing with the existing Harry Potter world's problems.
