First, think about the origin of the Demonic Grimm. If it was created from some dark, ancient magic, it might have an otherworldly and terrifying look. For example, it could have a smoky, ethereal body with a skull - like face that constantly changes expressions to show its malevolence. Its attacks should be unique and deadly. Maybe it can drain the life force of its enemies just by touching them. And don't forget about its behavior. A Demonic Grimm that stalks its victims silently, always lurking in the shadows before pouncing, would be very scary.
One plot idea could be a group of hunters discovers a new type of Demonic Grimm that can possess other Grimm, creating an army. They have to find the source of this new threat and stop it before it overcomes all of Remnant. Another could be a young huntress in training who has a special ability to sense Demonic Grimm and she teams up with some unlikely allies to face a powerful Demonic Grimm lord that has been hidden for centuries. A third idea is that the Demonic Grimm start to corrupt the minds of some of the hunters, turning them against their own kind, and the remaining hunters have to fight both the Demonic Grimm and their former comrades.
One idea could be a story where Velvet discovers a new type of Grimm with unique abilities. She then has to figure out how to combat it, using her skills and the help of her friends. Maybe she could study the Grimm's behavior and weaknesses in secret to surprise everyone when she reveals her knowledge.
One possibility is that friendly Grimm could completely change the dynamic of the RWBY world. Instead of being pure threats, they might become allies or at least neutral entities. This could lead to new storylines where characters have to re - evaluate their understanding of the Grimm. For example, Ruby might be initially hesitant to trust a friendly Grimm but then realizes it can help in a certain situation.
A 'rwby smart grimm fanfic' could be about Grimm in the RWBY universe that are unusually intelligent. It might explore how these smart Grimm interact with the hunters and huntresses, and how they strategize during battles. Maybe they could even form alliances or have complex motives that are different from the typical mindless Grimm we usually see in RWBY.
Well, it could be about many things. It might be a fan - made story that combines the dark and menacing Grimm from RWBY with some sort of fantasy elements. Maybe it features the RWBY characters in a new adventure where they have to deal with the Grimm in a more fantastical setting than in the original show.
First, know the RWBY universe well. Research about the Grimm, their types, behaviors, and how they interact with the characters. Then, come up with an interesting plot. It could be centered around a battle against a powerful Grimm, or a mystery related to the Grimm. Next, develop your characters. If you're introducing new characters, give them distinct personalities. Write in a clear and engaging style, and don't forget to proofread for grammar and spelling mistakes.
Some fanfic ideas could involve Grimm hybrids. For example, a Grimm that is part wolf and part snake, with the speed of a snake and the strength of a wolf. Another idea is to write about a world where the Grimm are not just mindless monsters, but have a complex society among themselves. How would the RWBY characters deal with that? Also, a fanfic centered around a character who has the ability to communicate with Grimm, but has to keep it a secret from everyone else.
The common themes in 'rwby grimm oc fanfic' include transformation. The OC might go through physical or mental transformations throughout the story. For example, they could start as a more bestial Grimm - like form and gradually become more human - like. Another theme is friendship. Despite being a Grimm OC, they can form strong bonds with other characters. And the theme of discovery is also there, as the OC discovers new things about themselves, the RWBY world, and the secrets behind the Grimm.
Another theme is identity. Since the Grimm Queen is such a complex character, many fanfics try to figure out who she really is, what makes her tick, and how she came to be. They might explore her past and how it has shaped her present self. For example, some fanfics might show her as a once - good character who was corrupted by power or some tragic event in her past. This exploration of identity gives depth to the character and the story as a whole.
