Well, in a 'sentient grimm rwby fanfic', the sentient Grimm might develop their own culture or society. They could have unique forms of communication that are different from what we expect in the RWBY world. This could lead to some really cool interactions with the human or Faunus characters, like trying to negotiate or form alliances in a strange and unexpected way.
One interesting concept could be how the sentient Grimm interact with the regular Grimm hierarchy. Maybe they have the ability to command or influence the non - sentient ones in ways that change the typical Grimm behavior patterns we see in the original RWBY series.
Sentient Grimm might also form alliances with certain characters or groups. This would completely shift the power balance in the story. Maybe a group of villains in RWBY would team up with the sentient Grimm to achieve their own goals, leading to a much more complex and unpredictable plot. They could also be a source of new information, like knowledge about ancient Grimm secrets or powers that no one else knew about, which could also drive the plot forward in new directions.
One interesting concept could be the struggle of a character being a child of Grimm. They might face discrimination from the normal RWBY characters who see Grimm as pure evil. For example, they could have unique powers that are a blend of Grimm and human - like abilities, which would make them both feared and potentially useful in the fight against Grimm.
One interesting concept could be the unique powers that a hybrid might possess. For example, a character who is part Grimm and part human could have the strength and ferocity of a Grimm combined with the intelligence and adaptability of a human. Another concept could be the internal struggle of such a hybrid. They might be shunned by both humans and Grimm, leading to a complex identity crisis.
In some Harry Potter fanfics, sentient magic might be shown as having a will of its own. For example, it could choose who to bestow its power upon. It might also interact with wizards in unexpected ways, like guiding them to hidden secrets or protecting them from dark forces.
One interesting concept could be combining the magical world of Harry Potter with the dark and fairy - tale - like elements of Grimm. For example, perhaps the Forbidden Forest could be filled with Grimm - style creatures that have their own unique magic. Another idea might be having characters from the Harry Potter series face Grimm - like challenges, like a witch who turns people into animals in a more Grimm - esque way than what we see in the original Potter stories.
One idea could be a story where a powerful Demon Grimm is awakened by an ancient ritual gone wrong. The main characters in RWBY have to team up with unexpected allies to defeat it. They might discover new powers or abilities within themselves during the battle.
One idea could be a story where a humanoid Grimm has the ability to blend in with humans and is on a mission to infiltrate Beacon Academy. It could create chaos by spreading false information among the students. Another idea is a humanoid Grimm that has a strange bond with a Huntsman, and they have to figure out if they can trust each other or not. And perhaps a humanoid Grimm that is actually a failed experiment of some sort of dark magic, and it's trying to find its place in the world of Grimm and humans.
One interesting concept could be the expansion of character backstories. For example, delving deeper into Ruby's early days of training before Beacon Academy. Another might be exploring new Grimm species that are more powerful and have unique abilities. Also, the relationships between characters can be further developed, like the friendship between Weiss and Blake, showing their interactions outside of the main plot.
One interesting concept could be the unique team formations. In RWBY, teams are crucial, and in a wargaming fanfic, it might explore different combinations of characters for strategic battles. For example, mixing the combat styles of Ruby's speed with Weiss's glyphs in new and unexpected ways.
One interesting concept could be exploring the backstories of minor characters in the RWBY game universe. For example, delving into the past of a random hunter or Grimm. Another could be alternate timelines where different events occur, like if a major character had made a different choice during a crucial battle. Also, fanfics might focus on the relationships between characters in more depth, such as the unspoken bond between teammates that wasn't fully explored in the game.
