Maybe a plot where Harry is the son of a major Olympian god, and he is sent on a quest that combines elements of the wizarding world and the world of Greek mythology. He could be searching for a powerful artifact that has significance in both worlds, like a magical weapon that was once used by a hero in Greek mythology and also has the power to defeat dark wizards.
Another plotline could involve the interaction between the demigods from Olympus and the students at Hogwarts. Harry could act as a bridge between the two groups. There could be a situation where they have to team up to fight a common enemy, perhaps a dark force that is threatening both the magical world and the world of the gods.
One possible plotline could be Harry's struggle with his dual heritage. He has to deal with the wizarding world of Harry Potter and the Norse mythology world of Loki. For example, he might face challenges in learning magic in a way that combines both magical systems. Another plotline could involve his relationships with other characters. Since he is the son of Loki, he might have a more complex and devious side to his personality, which could create interesting dynamics with his friends like Hermione and Ron. They might be initially suspicious of his motives at times.
One possible plotline could be Harry's internal struggle with his heritage. Since Grindelwald was a dark wizard, Harry might battle with the idea of having such a connection. He could face prejudice from the wizarding world while also trying to understand if there are any redeeming qualities in Grindelwald's ideology that might be passed on to him.
One interesting plotline could be how Harry discovers his new 'Son of Fate' identity and the powers that come with it. Maybe he has an even deeper connection to the magical world's origin.
One interesting plotline could be Harry exploring his new powers as the son of Hypnos. Maybe he can use sleep - related magic in unique ways, like putting his enemies into a deep slumber during battles.
Well, in this fanfiction, a great plotline could be Harry's training. Since he's the son of Thor, he might have to undergo special training in Asgardian combat and magic. This could lead to some really cool scenes where he combines his wizarding skills with his Asgardian strength. Also, there could be a plot where he has to prove himself worthy to both the wizarding world and Asgard, which would create a lot of internal and external conflicts for him.
Well, perhaps a plotline where Harry has to use his Pegasus - related powers to save Hogwarts from a new and mysterious threat. Since he is the son of Pegasus, he might have the ability to fly faster and more gracefully than on a normal broomstick, allowing him to reach places quickly and perform daring rescues. Also, his connection to Pegasus could lead to new magical creatures being introduced into the story, like more mythical flying beasts that he can befriend or control.
Well, in some 'Harry Potter son of Morgana' fanfictions, there could be a plotline where Harry tries to uncover the truth about his mother. He might go on a journey through ancient magical libraries or seek out old magical families who knew Morgana. This could lead to him finding secrets about his own powers and his place in the wizarding world. He may also have to deal with the political implications of being related to Morgana, as there could be factions in the wizarding world who either want to use him or eliminate him.
One possible interesting plotline could be how Harry, as the son of Revan, discovers his true heritage. Maybe there are secrets hidden in the wizarding world related to his father that he has to uncover. Another could be his interactions with the existing characters in the Harry Potter universe. For example, how would Dumbledore react to this new aspect of Harry's identity? And how would Harry's relationship with his friends like Ron and Hermione change as he delves into his newfound lineage.
One possible plotline could be the son having unique magical abilities that are different from Harry's. For example, he might be able to communicate with magical creatures in a way no one else can. Another could be the son getting lost in a time - traveling adventure and meeting Harry's parents. Or perhaps he discovers a hidden part of Hogwarts that holds a great secret related to his family.
One possible interesting plotline could be Harry's discovery of his connection to Artemis. This might lead to him having unique powers related to the moon or the hunt, like enhanced archery skills or the ability to communicate with certain magical creatures associated with Artemis.
