One common theme is the struggle for power. Witch OCs often have to deal with their own powers and how they compare to other powerful entities in the Soul Eater world. Another theme is identity. Since they are original characters, a lot of fanfics explore who they are, where they come from, and what their purpose is. And of course, there's the theme of good vs. evil. Some witch OCs might be on the side of good, trying to fight against the real evil in the Soul Eater universe, while others might be more morally ambiguous.
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.
Sure. You can start by looking on fanfiction.net. There are often many great works there. Some might focus on the unique powers and backstories of original character witches in the Soul Eater universe. Another place to check is Archive of Our Own (AO3). It has a wide range of fanfics with different themes and writing styles related to Soul Eater Witch OCs.
First, give her a unique appearance. Maybe she has a distinct color scheme in her magic or an unusual style of dress. For example, she could have purple lightning - like magic and always wear a long black cloak with red trim. Second, define her powers clearly. It could be something like the ability to control shadows or transform into a particular animal. Third, give her a strong motivation. She might be seeking revenge for a wrong done to her family or striving to prove that witches can be good.
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.
To develop a character for a Soul Eater OC fanfic, start with their motivation. What drives them? Is it revenge, justice, or something else? Next, decide on their personality traits. Are they brave or cautious? Funny or serious? Their relationships with other characters are also important. Do they have a best friend? An enemy? And don't forget about their flaws. A character with flaws is more relatable. For instance, they might be overconfident and it gets them into trouble sometimes.
Well, Naruto's powers would likely be a mix of his ninja skills and his witch powers. His ability to create shadow clones might be enhanced by his witch heritage. In the Soul Eater universe, these clones could potentially have their own souls or be made up of a different type of energy. His Nine - Tails chakra, if it exists in this fanfiction, could also be affected. It might react with the witch magic in unexpected ways, like creating a new form of power that combines the raw power of the Nine - Tails with the magical aspects of being a witch. This new power could be used to combat the kishin or other powerful enemies in the Soul Eater world.
A common theme could be the clash of two different worlds. Since Naruko is from the Naruto world which has its own set of rules and powers, and Soul Eater has its unique universe, the fanfics might explore how these two worlds interact. Another theme could be the relationship between Naruko and the characters from Soul Eater. It could be a friendship or a romantic relationship that forms as they face challenges together.
One possible fanfic could be about Crona's journey of self - discovery. In the world of Soul Eater, Crona has always been an outcast. The fanfic could explore how, as a girl, she tries to break free from the chains of her past and the control of her mother. Maybe she starts to make real friends at the DWMA, like Maka and Soul, and they help her to see her own worth.
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.
