A plotline might involve Athena taking on a human form to be closer to Harry. She could use her wisdom to guide him in a different way than Dumbledore did, and their relationship could grow from there. Or perhaps in a time - travel fanfiction, Harry goes back in time and meets Athena in the past, and their love story begins in a completely different era of the wizarding world. There could also be a plot where Athena is the key to solving a mystery in the wizarding world that Harry is involved in, and their love blossoms during the process.
One possible plotline could be Harry's struggle with his identity. Since Athena is the goddess of wisdom and Artemis is associated with the moon and hunting, he might have an in - born affinity for both knowledge and nature. He could be constantly torn between the two aspects of his heritage, for example, feeling the pull towards both the academic world of Hogwarts and the wild outdoors. Another plotline could involve him having unique magical abilities passed down from his 'divine parents'. Maybe he has an uncanny ability to understand ancient magic related to the domains of Athena and Artemis, like spells related to the moon's phases or wisdom - based incantations.
One possible plotline could be about the Weasley family trying to improve their financial situation. Maybe they come up with a new business idea in the wizarding world, like a magical product that becomes a huge success and changes their economic status. Another could be a story about how the Ministry of Magic regulates the financial system in the wizarding world, and there are some characters who try to manipulate or reform it.
Well, one possible plotline could be a story where a character from the wizarding world, perhaps a powerful wizard, takes on a concubine in a parallel world or an alternate version of the wizarding society. The concubine might be from a different magical culture and their relationship could cause political or social unrest within the wizarding community.
One possible plotline could be that the parrot is a magical pet of a new character who enters Hogwarts. This parrot has the ability to detect dark magic, so it helps the students in their fight against the forces of Voldemort.
One possible plotline could be Harry being secretly trained by an unknown figure to become an assassin against the dark forces. He would have to hide this new identity from his friends at Hogwarts.
A plotline could involve an Eldrazi being brought to Hogwarts by a dark wizard who wants to use its power for evil. The students then have to work together to contain it. Along the way, they learn about the Eldrazi's nature and find that it's not entirely what they expected. There could be some interesting character development as they face this new and powerful threat.
One plotline could be Naruto being a transfer student at Hogwarts. He might struggle to adapt to the magic system while also showing off his ninja skills. Another could be Naruto teaming up with Harry Potter to fight a common enemy that threatens both the ninja world and the wizarding world.
One possible plotline could be that Harry, after some dark magic influence or a strange accident, starts to show Joker - like behavior at Hogwarts. He might play cruel pranks on his classmates and teachers, using his magic in unexpected and unethical ways.
One possible plotline is that Broly is brought to the Harry Potter world as a result of a powerful spell gone wrong. He initially causes chaos with his strength but then gradually learns about the concept of magic and starts to respect it. Another could be that Broly is a hidden protector of Hogwarts, his Saiyan powers being the ultimate defense against a new dark force that the normal magic in the wizarding world can't handle.
A possible plotline could be that Harry uses his invisibility to spy on Voldemort's followers and gather intelligence for the Order of the Phoenix. This would add an element of mystery and danger as he has to be extremely careful not to be detected.
