In fanfiction, if Harry Potter's wand fuses with the Elder Wand, it could potentially create an extremely powerful magical object. Harry already has a strong connection with his own wand, and the Elder Wand is known for its near - omnipotent power. The fusion might result in him having an unrivaled control over magic, perhaps being able to perform spells with ease that were previously difficult or even impossible. It could also change the balance of power in the wizarding world, as he would be in possession of a wand that combines the loyalty and unique properties of his original wand with the raw power of the Elder Wand.
Well, it could lead to some really interesting plot developments. For one, Harry's already special connection to magic might be enhanced exponentially. Since his wand has sort of 'chosen' him and the Elder Wand is a symbol of great power, the fusion might give him the ability to tap into ancient and forgotten magics. Maybe he could use it to heal wounds that are otherwise incurable or even to communicate with magical creatures on a whole new level. It would also make him a target for those who seek power, like some dark wizards who would stop at nothing to get their hands on such a powerful wand.
In some fanfictions, if Harry Potter keeps the Elder Wand, he might use it to strengthen the magical defenses of Hogwarts. He could make the school impervious to dark magic attacks, ensuring the safety of the students and staff.
One interesting wand fuse could be Harry's wand with Dumbledore's elder wand in fanfiction. This might result in a wand that has not only the loyalty - based power of Harry's wand but also the ultimate magical might of the elder wand. It could be used to rewrite certain parts of the wizarding world's history or even restore lost magic.
The fusion could be shown as a chaotic yet beautiful event. Sparks could fly from the wands as they touch, and the magic within them could seem to fight at first, like two different forces trying to assert dominance. But then, as they start to meld, the chaos gives way to harmony. The colors of the magic, say the warm red - gold of Harry's wand and the cold, steely grey of the Elder Wand, could blend into a new, unique color. And the resulting fused wand would look as if it was crafted by the most skilled wand - maker, with an otherworldly beauty and an aura of great power.
One reason could be Harry's pure heart. The Elder Wand might be attracted to his selfless nature. Another could be his connection to Voldemort. Since they are linked in many ways, the wand might see Harry as the key to resolving that conflict.
If Harry's wand were to fuse with another, say Hermione's, it could create a stronger bond between them. They would have to rely on each other more to understand the new powers of the wand.
If Harry Potter snapped his wand in fanfiction, it would be a huge turning point. Maybe he'd start a journey to repair it, like finding some ancient magic or a powerful wizard who could fix it. Or he could discover latent powers within himself that didn't rely on the wand. It would be a great opportunity for the writer to explore different aspects of Harry's character and the magic world without the typical wand - based magic.
Another example could be a wand made from fusing Neville Longbottom's wand with Harry's. Neville's wand is known for its connection to plants and growth magic. When fused with Harry's wand, it could potentially create a wand that can rapidly grow and control magical plants on a large scale. This could be used to defend a wizarding village by creating a thicket of enchanted thorns around it in minutes.
The Elder Wand choosing Harry has a huge impact on the plot. It gives Harry an edge over Voldemort. Since the wand is the most powerful, it makes Harry a more formidable opponent. It also adds an element of destiny to the story, as if Harry was meant to be the one to defeat Voldemort all along.
One idea could be that when the wands fuse, they create a new, super - powerful magic that the wizard or witch has to learn to control. Maybe it gives the ability to perform spells that were previously thought impossible in the Harry Potter universe.
One interesting 'Harry Potter Elder Wand' fanfic could be one where the Elder Wand has a sentience of its own and it tries to guide the wizard who wields it towards a different destiny than what is expected in the original series. It might lead the wizard to uncover secrets about the wand's true origin that were long forgotten.
