Naruto might be a staff - type weapon. He could use it for both close - range combat and to channel his chakra or soul power. The staff could have different forms, like it could extend or transform into other shapes depending on the situation, similar to how he can transform his Rasengan.
One idea could be to create an OC weapon that is a scythe with a hidden blade. It could have a unique backstory, like it was forged in a forgotten realm. The character using it could be a bit of a rebel, not fully conforming to the rules of the Death Weapon Meister Academy.
In a fanfiction where Black Star becomes a weapon, his design as a weapon would probably be very unique. Given his love for being flashy and his ninja - like style, he could be a weapon that has a lot of sharp edges and a sleek, black design. Maybe he'd be a sword with some sort of special ability related to his ninja skills, like being able to disappear and reappear during combat, or having the ability to cut through dimensions.
One common theme is self - discovery. Since the OC weapons are often new creations in the fanfic world, they usually have to figure out their powers, which is like a journey of self - discovery. For example, they might find out they can transform in unexpected ways or have special abilities they didn't know about.
Create a multi - layered plot. Maybe there's a mystery surrounding the origin of the OC weapon. As the fanfiction progresses, the characters start to uncover clues about its creation and purpose. At the same time, there could be a romantic sub - plot between the meister and another character at the academy. This adds depth to the story and keeps readers interested. Also, don't forget to have a climax where the characters face their biggest challenge yet and a satisfying resolution at the end.
Well, perhaps Harry could be a weapon that has the power of his magic from the Potter world. He might be used by a Soul Eater character to fight against evil souls. Maybe his wand could transform into a more weapon - like form in the Soul Eater world.
It's rather unique. Combining the magical world of Harry Potter with the concept of Weapon Soul Eater is not something you see every day. Usually, fanfictions tend to stay within the same universe or have more common crossovers. This one seems to blend two very different and popular franchises in a new way.
One great Soul Eater Weapon OC fanfic is 'The New Weapon in Death City'. It has an interesting plot where the original character is a weapon with a unique transformation ability. The story focuses on how this OC weapon interacts with the main characters from the Soul Eater universe, bringing new challenges and friendships.
Naruto could be seen as a weapon that has the spirit of a ninja within it. His chakra system might be reworked to be more like the soul wavelength in Soul Eater. His Nine - Tailed Fox power could be a hidden, extremely powerful aspect of the weapon. He would likely have a strong sense of justice still, but it would be expressed in the context of the Soul Eater universe, like fighting to protect souls instead of the Hidden Leaf Village.
One great Crona x Soul fanfiction is 'The Bond Beyond'. It delves into how Crona and Soul's relationship develops in a more in - depth way than in the original series. It shows them learning about each other's pasts and how they grow together. Another one could be 'A Different Kind of Friendship'. This fanfiction focuses on how they start as friends but there are hints of deeper feelings emerging as they face various challenges in the world of Soul Eater.
