What would 'harry potter is a demigod fanfiction' entail?

It could entail a story about a Nundu being used in the Triwizard Tournament as an unexpected and extremely dangerous challenge. The champions would have to figure out a way to survive the encounter with the Nundu without using dark magic.

One idea is that there's a new spell in the Harry Potter universe that involves lemons and unicorns. Harry Potter could be the first to discover it while interacting with a unicorn. Maybe it's a spell that can transform things into lemon - flavored magical treats for a short time, and the unicorn is the key to unlocking this spell.

It would be really wild. Maybe Harry Potter would have some of Ulquiorra's powers like his cero blast, but in the form of a wizard spell. Or perhaps he would have Ulquiorra's cold and emotionless demeanor in the wizarding world, which would be a huge contrast to his normal self. He could be dressed in a way that combines the Hogwarts robes with Ulquiorra's Arrancar outfit.

It would probably involve Harry Potter having Spartan - like abilities. Maybe he could be super strong and agile like a Spartan, while still being able to use magic. It could also include elements of the Halo universe, like the Covenant or the UNSC, interacting with the wizarding world.

It would be a very interesting mix. Harry might have new powers from being Zeus' son, like the ability to control lightning. His Hogwarts adventures could be intertwined with tasks given by Zeus or dealing with other Greek mythological creatures.

The plot might involve Harry using his magic in an unorthodox way to summon Cthulhu. Maybe he stumbles upon an ancient spell in the restricted section of the library. Once summoned, Cthulhu could bring chaos to the wizarding world. The dark and eldritch powers of Cthulhu would be in stark contrast to the more traditional magic in Harry Potter. This could lead to a struggle between the forces of Hogwarts and the indescribable horror of Cthulhu.

Definitely not. Harry Potter focuses on the adventures of a young wizard in a world of magic, with Hogwarts, wizards, witches, and dark lords. It doesn't draw from the concept of Norse demigods in the way fanfiction would.

Perhaps they are misinformed. They might have seen some similarities in themes like heroism or magic that exist in both, but in reality, the two are very different.

There could be major power shifts. For example, the main characters might start to rule Hogwarts in an 'Overlord' - like way instead of following the traditional school hierarchy. Maybe Harry Potter himself could become more of a tyrant - like figure, using his powers not just for good but also for self - gain.

The plot could involve Harry Potter being reborn in the Vampire Diaries universe with his magical abilities intact. He might face new challenges like dealing with vampires and witches in this different magical setting. Maybe he'd use his spells to protect himself from vampire attacks or form alliances with some of the characters. For example, he could team up with Bonnie Bennett, sharing magical knowledge. And he'd surely have to adapt to the different social structures and power dynamics in Mystic Falls.
