In 'evil rwby fanfic', one characteristic could be the subversion of the typical RWBY narrative. Instead of the usual fight - for - good - against - evil, it might show the characters being on the wrong side of the battle. Maybe Ruby could be leading a group with a not - so - noble cause. The power dynamics and relationships between characters would also be re - imagined in a more negative light, like Weiss and Blake having a toxic friendship instead of a positive one.
Well, 'evil rwby fanfic' can both enhance and distort the perception of the original RWBY series. On one hand, it can add depth to the understanding of the characters' potential, as it explores their 'evil' versions. This can make fans think more about the character development in the original. On the other hand, if it's too far - fetched, it can make the original seem too simplistic in comparison. For example, if in the fanfic Ruby is made out to be a cruel dictator, it might be hard for some fans to reconcile that with the kind - hearted Ruby in the original.
The combination of different powers and abilities. RWBY characters have their unique semblances and weaponry, and Resident Evil has its own set of weapons and mutated creatures. In a crossover fanfic, seeing how these elements interact, such as a RWBY character using their semblance to fight a Resident Evil boss, can be very exciting. For instance, Blake's shadow clones could be used to confuse a Tyrant. Also, the exploration of how the two different storylines and settings merge. Whether it's the Umbrella Corporation getting involved in RWBY's world or RWBY characters stumbling into a Resident Evil - like scenario in their own world, it creates a whole new set of possibilities for the story.
Another one is 'Resident Remnant'. In this fanfic, the writers do a great job of integrating the lore of both series. They create a scenario where the bioweapons from Resident Evil are introduced to RWBY's world, and the story follows how the characters adapt and fight back. It has some really cool action scenes that are a blend of RWBY's fast - paced combat and Resident Evil's survival horror elements.
One common theme could be the corruption of the main RWBY characters. For example, they might be turned to the dark side and start acting in ways that are completely opposite to their original nature, which creates a stark contrast.
A prevalent theme is also the re - imagining of the power structure. In an evil parallel universe, the Dust and semblance powers might be used for evil purposes. For instance, Ruby's speed semblance could be used to quickly carry out heinous acts. Also, the theme of a corrupted Beacon Academy often comes up, where it becomes a breeding ground for evil instead of a place to train heroes.
I'm not sure of specific 'evil rwby stark contrast fanfic' to recommend. You could try searching on popular fanfiction websites like Archive of Our Own. They have a large collection of RWBY fanfics and you might find what you're looking for there.
One possible plot could be Ruby being betrayed by her closest friends. Maybe she discovers a dark secret about the Huntsman academies that makes her question everything she has ever believed in. This disillusionment could start her on the path to evil as she feels that the system she has dedicated her life to is corrupt.
In the 'evil rwby parallel universe fanfic', it could be that there is no Beacon Academy as we know it. Instead, there is a place where they train people to be evil enforcers. The relationships between the characters are also twisted. For example, Weiss might be in a power struggle with Ruby, constantly trying to undermine her to gain more control within their evil group. The world itself could be a darker version, with different kingdoms that are all in a state of constant war and strife.
The characters could also have different relationships with the Grimm. Instead of fighting them, they could be using the Grimm as tools. They might have some sort of ability to control or communicate with the Grimm. Their backstories would need to be adjusted accordingly. For example, Ruby might have had a traumatic experience that led her to turn evil, like losing someone she loved and blaming the world for it, which then made her decide to take over and reshape it in a more cruel way.
