Well, often in these fanfics, a major plot twist is the technology or magic system. In the RWBY universe, Dust is important. But in the alternate universe, it could be that Dust has no power, or it has some completely different and unexpected effect. And the semblances of the characters might change drastically. Say, Yang's ability to absorb damage and use it as strength could turn into something like the ability to heal others instead. And then there's the world - building aspect. The alternate universe could be a post - apocalyptic wasteland instead of the somewhat civilized world we see in RWBY, which would be a huge plot twist for the characters to deal with.
One common plot twist could be the revelation of a character's unexpected heritage. For example, a seemingly ordinary character might turn out to be related to a powerful clan. Another could be the betrayal of a trusted ally. In the Naruto universe, where loyalty is highly valued, this can be a huge shock. And sometimes, a long - dead character might be brought back to life in a very unexpected way, like through some ancient and forgotten jutsu.
In some fanfictions, a plot twist could be Peter losing his powers and having to rely on his intelligence alone. For example, in 'Powerless Peter', he has to use his scientific knowledge to outwit villains. Another is when the alternate universe has Peter's loved ones turn against him. In 'Betrayed by Aunt May', Aunt May becomes a villain, which is a huge shock. And sometimes, Peter is from a different time period in the alternate universe, like in 'Peter from the Future', and that changes the whole dynamic of the story.
Well, at first, the characters would be in shock. But then, Ruby would step up. She's adaptable, so she'd start learning about the new rules of combat, the types of Grimm or other threats in this alternate universe. Yang would be a bit more brash. She might get into some fights to test the waters. Weiss would be analyzing everything from the political systems to the economic structures. She'd try to find a place where she could use her family's influence (if there's an equivalent in the new world). Blake would be on the lookout for any signs of oppression, especially if the Faunus situation is different. She'd also be the one to make sure the group doesn't do anything to offend the local cultures. All in all, they'd have to learn new fighting styles, new languages, and new ways of interacting with others.
In a fanfic where Summer Rose is alive, the plot could center around her teaching Ruby and Yang new combat techniques and strategies. She could also introduce them to a network of Huntsmen and Huntresses that she has been a part of. This would lead to new adventures and battles. Perhaps she takes them on a journey to a far - off land where a new type of Grimm has been discovered, and they have to work together to figure out how to defeat it.
Well, Hermione is often depicted in different ways in these fanfics. In some alternate universes, she could be a powerful dark witch instead of the studious and good - hearted character we know. Ron might be a super - confident and arrogant character rather than the sometimes insecure boy in the original story. Also, Snape could be a completely different person. He could be a jolly and friendly teacher rather than the brooding and complex one we are used to.
One interesting concept could be the different versions of the characters in the alternate universes. For example, a Ruby in a steampunk - themed alternate universe might have a different weapon design and fighting style. Another concept could be how the relationships between the characters change. Maybe in one alternate universe, Weiss and Blake are bitter enemies instead of friends. Also, the alternate universes could have different rules for Dust, which would lead to unique battles and power - ups.
One possibility is that the relationships between the characters are altered. Weiss might find that in this parallel universe, she has a closer bond with someone she was not as close to in her own universe, like Blake. They would have to adapt to these new relationship dynamics while also trying to figure out how to get back to their own universe if that's their goal.
In this fanfic, they might encounter alternate versions of themselves. For example, Harry could meet a version of himself who is a dark wizard instead of a hero. Teddy, with his shape - shifting ability, could have a hard time adjusting to the new universe where the rules of magic might be different. They may also find new magical creatures that don't exist in their original universe and have to figure out how to interact with them.
One common plot twist could be that the injury was actually self - inflicted on purpose for a greater good, like a sacrifice play. Another might be that the person who caused the 'hurt' was actually being mind - controlled. And sometimes, the injury might turn out to be a fake to deceive the enemy.
In the Overlord of the Universe novel, there is a plot twist where the entire universe's power structure is turned upside down. The main character, who was thought to be just a regular powerful being, is revealed to be the key to a much larger and more complex plan that spans across different dimensions. This revelation not only changes the way the other characters view him but also sets off a series of events that are full of suspense and action. It shows that the story is much more than just about a powerful individual but about the fate of the entire universe.
