He could obtain it through a strange twist of fate. Maybe during a mission in a dimension where the Harry Potter world and the Naruto world collide, he stumbles upon it. It could be lying in an ancient tomb, and Naruto, being curious, picks it up and unknowingly becomes its master.
A Naruto Elder Wand fanfiction could also explore how Naruto's chakra system interacts with the magic of the Elder Wand. The wand might react differently to his chakra compared to regular magic users. Perhaps Naruto could use his chakra to heal the wand if it was damaged, creating a unique bond between him and the powerful magical artifact.
He'd be extremely powerful. His already formidable ninja skills combined with the Elder Wand's magic would make him nearly unbeatable. He could use it to perform feats like instantly transporting across great distances within the Naruto world, or even to other dimensions if the wand's magic allowed for that.
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.
In a fanfiction where Naruto has the Elder Wand, he might become an even more powerful force. He could use the wand's magic to enhance his already formidable ninja skills. For example, he could combine his Rasengan with magic spells from the wand, creating new and unbeatable attacks. Maybe he'd use it to protect Konoha in ways that normal ninja techniques couldn't, like creating large - scale magical barriers around the village.
Daphne could be a researcher of ancient magical artifacts and she comes across some information about the Elder Wand that she shares with Harry. For instance, she might have found a dusty old book in the library that details a secret property of the wand. This information could be crucial for Harry in his journey regarding the wand.
He could keep it by disguising it as an ordinary object. For example, he could use a transfiguration spell to turn it into a simple stick or a quill. That way, no one would suspect it was the Elder Wand.
They could inherit it. Perhaps their family has a long - forgotten attic where the mithril wand has been stored for generations. One day, while exploring, they stumble upon it.
In some fanfictions, Draco Malfoy might obtain the Elder Wand by chance. This could lead to a whole new set of adventures. Maybe he uses it to protect his family or to rewrite his own story within the wizarding world. It often depends on the creativity of the fanfiction writer.
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.
The Elder Wand is a key plot device. Its changing ownership creates a lot of tension and action. For example, when Voldemort tries to gain control of it, it sets off a chain of events that leads to many battles and confrontations.
