A possible plot could be that Harry's Magneto powers are discovered by Voldemort. Voldemort sees this as a threat and tries to either kill Harry or turn his powers to his own advantage. Harry, on the other hand, uses his powers to gather a group of resistance wizards and magical creatures. He uses his ability to manipulate metal to create powerful defenses against the Death Eaters. Along the way, he also discovers that his powers are linked to an ancient magic that was long forgotten in the wizarding world.
The plot could involve Harry initially being confused by these powers. He might accidentally use them in the wizarding world and cause chaos. For example, during a potions class, his powers could make all the metal cauldrons fly around. Then, he has to figure out how to control them with the help of some unlikely allies, like a Muggleborn who has knowledge of science and Magneto from the X - Men world who somehow crosses over into the Harry Potter universe.
If Harry Potter had Magneto's powers in fanfiction, it would completely transform his character. He might not rely so much on his wand for combat. Instead, he could manipulate the metal in the environment, like the suits of armor in Hogwarts. This would give him an edge in duels, as his opponents wouldn't be expecting such non - traditional magic. Also, it could potentially make him a target for those who fear powerful and different abilities, just like Magneto was in the X - Men universe.
Well, one possible plot could be that Magneto, with his strong views on mutants and power, would train Harry to be extremely powerful in magic. Harry might grow up with a more aggressive stance towards those who oppose him, like Voldemort. He could use his magic in ways that are more combat - oriented from a young age.
Well, it could start with the revelation that Harry Potter has a hidden connection to Magneto. Maybe his magical abilities are somehow related to Magneto's mutant powers. The plot could involve Harry having to deal with both the wizarding world and the mutant world. He might use his combined powers to fight a common enemy that threatens both worlds.
The story would change a great deal. He could use Magneto's powers to enhance his ability to escape from dangerous situations. For instance, if trapped in a room with metal bars, he could simply bend them and get out. His dueling style would also be different. Instead of just using spells, he could incorporate his power over metal to surprise his opponents.
Naruto would be even more confident. Having Magneto's powers would give him an edge he didn't have before. He'd be able to take on stronger opponents with ease. His brash and fearless nature would be amplified. He might be a bit more reckless at first as he experiments with his new powers.
One great fanfiction could be 'Harry Potter: The Magneto Legacy'. In this, Harry discovers his newfound Magneto - like powers and has to navigate the wizarding world while hiding this strange new ability. It has an interesting plot where he uses his powers to protect Hogwarts from a new dark threat in a unique way.
If Harry Potter were to join Magneto in fanfiction, it would be an interesting blend of two different fictional universes. Harry's loyalty and courage could potentially influence Magneto. Maybe Harry would try to convince Magneto to use his powers in a more benevolent way. On the other hand, Magneto's experience in fighting for the rights of the oppressed could give Harry new perspectives on the treatment of Muggle - borns in the wizarding world. Their combined forces would surely be a threat to any foe, with Harry's spells and Magneto's control over metal.
The powers might also change the way magic is perceived in the story. If Harry can do things like read minds or foresee events, it could make other forms of magic seem less powerful in comparison. Or it could inspire other characters to explore different, more psychic - related magic, thus expanding the magical lore in the fanfiction.
In such a fanfiction, Harry having Elsa's powers would completely change the dynamics of the wizarding world. Imagine Harry using his ice powers during the Triwizard Tournament. He could freeze the lake instantly in the second task, making it easier to retrieve what he needed. Also, he could create ice sculptures of magical creatures during the Yule Ball, adding a unique touch to the event. His relationship with his friends might also change as they'd be in awe of this new power.
His magic would likely be more physical and violent. Alucard's powers are very much about brute force in a way. So instead of the more refined spells Harry usually uses, he might be casting magic that has a more direct and powerful impact, like his spells could cause more destruction on impact.
