Ra could be a strong contender. Ra is one of the most well - known Goa'uld. In a Harry Potter fanfiction, he could use his vast knowledge and power to gain an upper hand. He might be interested in the Philosopher's Stone, for example, seeing it as a source of ultimate power. His Goa'uld abilities to control people could be used to manipulate wizards and witches to do his bidding in the search for magical items.
Apophis also has a chance. He was very cunning and ambitious. In the context of a Harry Potter crossover, he could use his deviousness to infiltrate the wizarding world. He might try to form alliances with dark wizards, like the Death Eaters, and use their knowledge of the Dark Arts along with his Goa'uld powers to become the most powerful. He could also use his ability to possess hosts to gain access to restricted areas in Hogwarts or other magical places.
Probably Anubis. He was extremely powerful among the Goa'uld. In a Harry Potter crossover, his ability to manipulate dark forces could be enhanced by the dark magic in the Harry Potter universe. He might be able to use spells like the Unforgivable Curses to his advantage and combine them with his Goa'uld powers.
It would be a really strange and exciting mix. Harry could have the Goa'uld's ability to possess others on top of his magical powers. He might use this to his advantage in battles against Voldemort, for example, by possessing Death Eaters. It would also change his relationships with his friends as they might be a bit scared or in awe of this new power.
Obviously, Harry Potter himself could be a main character. He could be drawn to Goa Uld because of some mysterious happenings that seem to be related to Voldemort or some other dark force.
She could be a powerful dark force. Maybe she'd use her possession abilities to take over key magical figures in the wizarding world, like professors or Ministry officials. This would create chaos as she'd use their knowledge and power for her own alien motives.
Obviously, Harry Potter would be one of the main characters. Hermione and Ron would likely be by his side as well. But there could also be new characters specific to the Goa Uld Host. Maybe a local wizard named Arjun who has a deep connection to the Goa Uld Host and acts as a guide for Harry and his friends. Another could be an elder of the Uld, a wise and powerful figure named Zara who has knowledge about the history of the host and the magic involved.
Well, the Goa'uld might initially be confused by the magic. They are used to their own technology and forms of power. Magic could be a new and difficult - to - understand concept for them. For example, if the Goa'uld tries to use its usual mind - control techniques, the magic in the wizarding world might resist it. Spells could be used to detect the presence of the Goa'uld in a host. And if the Goa'uld tries to fight back using its own powers, the magical shields and defenses in the wizarding world could prove to be a challenge.
One popular trope is the 'fish out of water' situation. For instance, a Hogwarts student suddenly finding themselves in the middle of a Stargate base surrounded by Goa'uld threats. Another is the power exchange trope, like a Goa'uld getting access to magic and how that changes the power dynamics.
One possible plot could be that in Goa, there is a hidden magical community. The Uld (assuming it's some sort of magical entity or group) could be hosting an event. Harry Potter and his friends arrive there and discover a new kind of magic that is unique to this place. They might have to face challenges related to local magic traditions and make new allies among the Goa wizards.
In Goa'uld Harry Potter fanfiction, there could be a concept where the Goa'uld symbiotes possess magical creatures in the Harry Potter world. Imagine a Goa'uld in a hippogriff or a dragon. This would not only change the nature of those creatures but also create a whole new set of challenges for the characters in the story. The Goa'uld's hierarchical society might also clash with the relatively egalitarian society of the wizards, leading to all sorts of power struggles and political intrigue.
One idea could be a story where Goa Uld is a new magical creature discovered in the Forbidden Forest at Hogwarts. The main characters, like Harry, Hermione, and Ron, have to figure out how to deal with it. Maybe it has some unique powers that can either help or endanger the wizarding world.
There are some interesting fanfictions out there that combine Goa'uld Queen and Harry Potter elements. One can start by looking on major fanfiction platforms like FanFiction.net or Archive of Our Own. You might find stories where the Goa'uld Queen's power dynamics are introduced into the wizarding world of Harry Potter, creating unique plot twists and character interactions.
