A plot could involve a Goa'uld escaping from its own realm and finding its way into the wizarding world. It chooses a random Harry Potter character as a host. The Goa'uld starts to use the character's knowledge of magic and the wizarding world to its advantage, trying to build its own little empire within Hogwarts. However, the magical nature of the wizarding world has some unforeseen effects on the Goa'uld, and the character's original personality starts to fight back against the Goa'uld's control. This internal struggle and the external attempts to stop the Goa'uld make for an interesting fanfiction story.
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.
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.
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.
A fascinating concept could be the Goa'uld trying to infiltrate the wizarding world. They might be interested in the powerful magic there. The fanfiction could explore how the wizarding community, with their unique spells and potions, would deal with the Goa'uld's attempts at invasion. There could be epic battles between the Death Eaters and the Goa'uld, or perhaps alliances formed between the good wizards and some Goa'uld rebels. This would make for a very complex and engaging story.
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.
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.
One plotline could be that the goa'uld symbiants are discovered in the Forbidden Forest. Harry and his friends, out of curiosity, start to investigate. As they learn more about the symbiants, they find out that there is a prophecy that links the fate of the wizarding world with the goa'uld. Harry then has to figure out how to prevent a catastrophe that would occur if the wrong goa'uld gets too much power in the wizarding world. This could involve traveling to different magical and goa'uld - related places, making new allies and enemies, and using both his magical skills and the new knowledge about the symbiants to save the day.
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.
There are some interesting fanfictions out there that combine Goa'uld Queen and Harry Potter elements.
