In a fanfiction where Harry Potter fights Sauron, Harry would be at a disadvantage in terms of raw power. Sauron is an ancient and extremely powerful being. However, Harry has his courage and quick thinking. He could use his ability to solve mysteries and puzzles. He might figure out a way to destroy the One Ring, which would be a huge blow to Sauron. But it wouldn't be easy as Sauron would be constantly trying to stop him.
Well, in such a fanfiction, Harry might use his magic skills like the Patronus charm to fend off the Volturi's attacks. Maybe he could also team up with his Hogwarts friends to create a powerful defense against the Volturi's mind - control powers.
One possible plot could be that Sauron somehow manages to enter the wizarding world. Maybe through a powerful dark magic spell that links the two universes. Harry, being the hero, senses the new and greater evil. He then has to figure out how to defeat Sauron, which is much more difficult than any foe he has faced before. He might have to learn about the power of the One Ring and how to destroy it, all while protecting Hogwarts and the wizarding world from Sauron's dark minions.
In a Harry Potter vs Imhotep fanfiction fight, it depends a lot on the setting. If it's in Hogwarts, Harry has the home - field advantage. He knows all the secret passages and can use the magic of the school to his benefit. Imhotep would be out of his element, but his sheer power might still make him a formidable foe. Harry could try to trap Imhotep in the Room of Requirement, but Imhotep might find a way to break free using his ancient magic. It would be a battle full of twists and turns.
In a 'Percy Fights Harry Potter' fanfic, perhaps they could fight over differences in their approaches to dealing with Voldemort. Percy, with his by - the - book attitude, might clash with Harry's more instinctive and unorthodox methods.
Well, one possibility could be that Harry discovers his true parentage as Sauron's son in a very shocking way. Maybe through some dark magic revelation. Then he might struggle with his identity, being a part of the wizarding world that he loves but also having this dark connection. He could face a lot of inner turmoil as he tries to decide whether to embrace his dark heritage or fight against it.
In this fanfiction, Harry might use his magical skills like the Patronus charm to fend off the dragon. Maybe he'd also rely on his broomstick flying skills to dodge the dragon's attacks.
Well, if Harry Potter were to fight the Hulk in fanfiction, Harry would likely be at a disadvantage initially. The Hulk's brute strength is on a whole different level. But Harry is smart and resourceful. He might use his invisibility cloak to get close and then hit the Hulk with a powerful blasting curse. The Hulk, though, would probably just get angrier and more powerful. It would be a really interesting battle to read about, with magic vs raw physical power.
If we consider Harry Potter fighting Thanos in fanfiction, it's a clash of two very different universes. Harry has his wand and his knowledge of spells. He could try to transfigure Thanos into something harmless, but Thanos' willpower might resist such magic. The Time - Turner could also be a factor if Harry could use it to his advantage, perhaps going back in time to prevent Thanos from getting the Infinity Stones. But Thanos' brute force and his army could pose a great threat to Harry. It would be a battle that would depend on Harry's quick thinking and ability to adapt his magic to this new and powerful enemy.
If Harry Potter fights Imhotep in fanfiction, Harry would likely start with his go - to spells. He might try a Stunning Spell or a Shield Charm. Imhotep, on the other hand, would probably use his powers of necromancy. Harry would be at a disadvantage in terms of not being used to dealing with an enemy who can raise the dead. However, Harry has the advantage of speed and agility in combat, which he has learned from his years at Hogwarts. So it would be a very interesting fight to read about.
In a fanfiction scenario where Harry Potter fights the Night King, it could be a very interesting battle. Harry has his magic skills like the Patronus charm which could potentially be used against the Night King's army of the dead. However, the Night King is extremely powerful and has the ability to raise the dead. Harry would need to find a way to counter this, perhaps by using powerful offensive spells like the Killing Curse. But he would also have to be careful not to get overwhelmed by the sheer number of the Night King's forces.
