Maybe an OC weapon that is a dual - bladed sword. The blades could have different elemental powers, such as fire on one and ice on the other. For the fanfiction, you could write about how the weapon's wielder has to learn to balance these opposing elements and use them effectively in battles against kishin - eggs.
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.
An interesting OC weapon could be a crossbow that fires arrows made of pure energy. The design of the crossbow could be very intricate, with gears and mechanisms that are not typical. In the fanfiction, the weapon might be discovered in an ancient temple, and the meister and weapon have to figure out how to use it properly while also facing threats from other characters who want to steal it.
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.
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.
Maybe an OC that has a special ability related to time. They can slow down time briefly during a fight. But this power comes with a cost, like it drains their soul energy quickly. The fanfiction could explore how they learn to control this power and balance its use while also dealing with the normal challenges at the DWMA, such as making friends and passing classes.
Well, you could have a witch OC fanfiction where the witch is an outcast among her own kind. She doesn't believe in the typical evil ways of witches and wants to use her powers for good. So she approaches the DWMA with an offer of peace and cooperation. Another plot could be that the witch OC has a hidden lair where she collects ancient artifacts that have the power to change the balance between witches and the DWMA. And a third plot idea is that the witch OC is in love with a DWMA student, and this forbidden love creates a whole lot of drama and challenges as they try to be together in a world where witches and DWMA are usually at odds.
Good plot ideas include your female OC trying to break a curse that has been placed on her weapon form. She might have to seek out a reclusive and powerful character for help. Also, a plot where she is framed for a crime she didn't commit in the Soul Eater academy and has to clear her name while also dealing with the real culprit who is still at large.
One idea could be an OC who has a unique weapon form that no one has seen before in the Soul Eater world. For example, an OC that can transform into a musical instrument like a harp that has the power to soothe or disrupt souls. Another plot could involve an OC who is a transfer student from a far - off place with a different type of soul wavelength training, and they have to adapt to the DWMA's methods while also teaching the others something new. A third idea is an OC who has a connection to a powerful and ancient soul that starts to cause problems as the story progresses.
One idea could be an OC who is a weapon with a unique transformation ability, like turning into a musical instrument for a really different combat style. Another idea is an OC from a far - off land, bringing new cultures and fighting techniques to the world of Soul Eater. Maybe an OC who is a miester with a special power to communicate with the souls of inanimate objects and use them in battles.
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 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.
First, think about her unique weapon form. Maybe it could be something like a celestial harp that can also transform into a scythe. Then, give her a distinct personality. For example, she could be shy but fierce in battle. Also, consider her backstory, like she comes from a long line of musicians but chose to be a weapon meister instead.
