What could be an interesting plot in a Stargate and Harry Potter crossover fanfic?

One idea could be that Voldemort discovers the power of the Stargate and tries to use it to gain more power. He could send his Death Eaters through the Stargate to conquer other worlds and bring back resources or powerful artifacts to help him in his quest to take over the wizarding world. The Order of the Phoenix would then have to follow through the Stargate to stop him.

The plot could involve Harry using his magic in the Stargate universe. Maybe he could use spells to help the Stargate teams in their battles against the Goa'uld. For example, a simple Stunning Spell could be very useful against the Jaffa warriors. He could also use magic to decipher some of the ancient technologies that the Stargate teams come across, since he has experience with ancient magic in his own world.

One main theme is the clash of cultures. The magical culture of Harry Potter and the technological culture of Stargate are very different, and seeing how they interact, like wizards being amazed by high - tech devices and Stargate personnel being astonished by magic, is a big part.

One possible plot could be that the One Ring somehow finds its way into the wizarding world. Harry and his friends discover it and realize its dark power. Meanwhile, some Hobbits from Middle - earth are accidentally transported to Hogwarts. They team up with the Hogwarts students to keep the Ring away from the dark wizards who want to use it for evil, just like Sauron in their world.

Maybe there's a prophecy in both worlds that foretells of a combined force from the wizarding world and the ninja world being the only way to defeat an ultimate evil. So, Naruto and Harry are brought together. They face challenges in understanding each other's cultures and powers at first. But as they train together, they find ways to merge their skills. For instance, Naruto's rasengan could be enhanced with a magical spell to create a more powerful attack.

One idea could be that the Death Eaters in Harry Potter form an alliance with the Goa'uld from Stargate SG1. The combined forces of dark magic and alien technology would be a huge threat. The heroes would then have to combine their skills, with the wizards using spells to counter the Goa'uld's energy weapons and the SG1 team using their military tactics against the Death Eaters. Another idea is that the Hogwarts students go on a field trip through the Stargate. They encounter various alien races and have to use their magic to survive and make friends. This could be a great way to show how magic can be applied in a completely different setting.

One possible plot could be that Hogwarts students discover a Stargate on the school grounds. Maybe it was hidden by a powerful wizard in the past who had visited other planets through it. The students, led by Harry Potter, could then start to explore different planets through the Stargate. They might encounter alien races that have magical abilities similar to theirs, leading to a cultural exchange of magic and technology.

Well, perhaps there could be a situation where a character from True Blood, like Sookie Stackhouse, somehow ends up at Hogwarts. She has her telepathic abilities which could be really interesting in the wizarding world. The Hogwarts students might be both fascinated and a bit scared of her. And then, she could get involved in some sort of mystery that Harry Potter and his gang are also trying to solve. Maybe there's a dark magic that is affecting both the magical folk and the vampires, and they have to work together to stop it.

One idea could be that Voldemort discovers a way to enter the DC universe and teams up with some of the Justice League's villains like Lex Luthor. The Hogwarts students and the remaining members of the Justice League have to join forces to stop them. The wizards can use their magic while the superheroes use their powers.

One possible plot could be that the Death Eaters in the Harry Potter world team up with the Akatsuki from Naruto. Harry and his friends, along with Naruto and his comrades, have to join forces to stop this powerful alliance. They could learn from each other's magic and jutsu. For example, Naruto could teach the wizards about chakra control, and the wizards could show Naruto some advanced spells for defense and offense.
