In RWBY fanfiction, you could explore how different species in Remnant have different immune systems. For instance, the Faunus might have an immune system that is more attuned to nature, allowing them to resist certain natural toxins better than humans. This could lead to interesting interactions between human and Faunus characters, especially in situations where they need to rely on each other's unique immunities to survive.
You could have a character's immune system be linked to their Aura. Since Aura is a form of energy that protects the characters in RWBY, it could be that a strong Aura also means a strong immune system. So when a character's Aura is depleted, they become more vulnerable to diseases or toxins.
One way could be by creating a character with a unique immune system ability. For example, a character who can heal rapidly due to an enhanced immune system, which could be a result of some experiment or natural mutation in the RWBY universe. This could add an interesting dynamic to battles and storylines.
In RWBY fanfiction, the immune response could be depicted in various ways. It might be related to how the characters deal with a new type of Grimm toxin. For example, some fanfics could show a character having an enhanced immune response due to their unique Aura training, which helps them fight off the negative effects more quickly than others.
Often, it's portrayed through the characters' ability to resist certain negative effects. For instance, if there's a disease - like condition caused by some dark magic in the fanfic, characters with stronger Auras might show a better immune response by not getting as sick or recovering faster.
One idea could be a character in the RWBY world suddenly getting a gamer system that allows them to level up their combat skills like in a video game. For example, they could see their 'HP' (health points) and 'MP' (mana points) bars, and earn experience by fighting Grimm. Another plot could involve using the gamer system to unlock hidden abilities or weapons within the RWBY universe. Maybe a character discovers a special 'quest' within the system that leads them to a powerful relic.
One interesting concept is the unique Semblance abilities. In RWBY system fanfiction, authors often explore new and creative ways of using Semblances. For example, a character might have a Semblance that can manipulate time in a different way than the ones shown in the original series. Another concept is the creation of new Grimm. Fanfic writers can design terrifying and unique Grimm with different abilities and appearances. Also, the relationships between characters can be developed in new and exciting directions, like a friendship between two characters who were originally enemies in the show.
There could be various such stories. Maybe they face challenges in daily life due to their vulnerable immune systems and have to take special precautions.
One implication is that he becomes a more formidable opponent in battles. Enemies who rely on poison - tipped weapons or poison - based jutsus would be at a disadvantage against him.
Well, one interesting idea could be exploring the backstories of minor characters more in - depth. For example, we could learn about the childhood of a random student at Beacon Academy, how they got their weapon, and what led them to enroll there.
One interesting idea could be the RWBY characters having to team up in new ways to combat the kaiju. For example, Ruby's speed might be used to quickly dodge a kaiju's attacks and find its weak spots. Another idea is the fusion of Dust technology with kaiju - like elements. Maybe they create new weapons that can both harm the kaiju and also harness some of their power. Also, the idea of kaiju having Aura or semblances of their own could be really cool, changing the dynamics of how the RWBY characters interact with them.
One idea could be a crossover where Starkiller's powers are introduced into the RWBY universe. Maybe he teams up with Team RWBY to fight a new, powerful Grimm that is immune to normal Huntsman attacks. His lightsaber skills and Force abilities would add a new dynamic to the battles.
