Who would be the main antagonists in a 'Harry Potter finds the One Ring' fanfiction?

Sauron, even in the context of this fanfiction crossover, could be an antagonist. His influence could reach the wizarding world through the One Ring. He might try to manipulate Harry or those around him to get the Ring back.

Obviously, Harry Potter would be one of the main characters. He is the one who finds the One Ring after all.

Well, perhaps Harry uses his magic to sense the One Ring's power. He might initially mistake it for a dark magical artifact from his own world. Then, he could start on a journey to figure out what this strange ring is, all while facing challenges from both the wizarding world (like Voldemort's followers thinking he has a new powerful weapon) and from Middle - earth forces that are also after the ring.

The main antagonists could still be Voldemort and his Death Eaters. Just because Harry is being raised by Moriarty doesn't mean Voldemort's threat disappears. In fact, Moriarty might see Voldemort as either a rival or a potential ally, which would add another layer of complexity to the story.

It could be the Death Eaters still. But with Harry being raised by Revy, they might face a much more formidable opponent. Harry would have a different set of skills and a more aggressive approach, so the Death Eaters would have to adapt. Another possibility could be some of the more corrupt wizards in the Ministry of Magic who don't like this new, unpredictable Harry.

Voldemort would still be a major antagonist. His goal of ruling the wizarding world and eliminating Harry Potter would remain. However, there could be new antagonists added due to Hawkgirl's presence. For example, some Thanagarian villains might follow Hawkgirl to the wizarding world and see the chaos Voldemort is causing as an opportunity to gain power for themselves. They could try to form an alliance with Voldemort or simply try to take over the wizarding world on their own.

It could be the Saiyans. In the Dragon Ball universe where Frieza exists, the Saiyans are often his enemies. Even if Harry is reborn as Frieza, the Saiyans' natural strength and warrior spirit would pose a great threat to him. They might not understand his new - found combination of magic and Frieza's powers and see him as an even greater danger.

Hermione would be extremely worried. She'd start researching right away, trying to find out all she could about the One Ring. She might try to find spells to contain or protect against its power. As for Voldemort, he would see the One Ring as a tool to gain more power. He would likely be overconfident in his ability to control it, not realizing that the ring could potentially control him instead.

In this fanfiction, the Death Eaters would remain as antagonists on the wizarding side. They follow Voldemort's ideology and would oppose Harry no matter who raised him. But also, there could be elements from Jean Grey's world that turn against Harry. For example, if there are mutants who fear that Harry's magic could disrupt the balance between mutants and humans, they might become antagonists. It would add a whole new layer of conflict to the story.

Sauron would surely be one of the main antagonists. His lust for power and domination over Middle Earth is well - known. In this fanfiction, he would see Harry Potter as a major threat to his plans.
