Some characters might be suspicious of her at first. After all, she's from the future and that's a very strange concept for them. They might think she's a witch or some kind of threat.
Her presence could also cause jealousy among some of the female characters if she catches the eye of a popular male character. This could lead to some interesting interpersonal dramas within the story, adding another layer of complexity to the fanfic.
Well, it could be about a girl from the future somehow getting transported to the time period of 'The Last Kingdom'. Maybe she has some special knowledge that helps the characters in the show. For example, she could know about future battles and warn them, changing the course of history in that fictional world.
His presence could disrupt the power balance. If he still has his strong Force abilities, he could be a major force (no pun intended) to be reckoned with. Those in power might see him as a threat or an opportunity. If he aligns with one side, it could tip the scales in their favor.
If Bardock arrives on Namek in the fanfic, it could also change the fate of the Dragon Balls. Instead of being just a tool for Frieza or the Z - fighters to use, Bardock could have a different vision for them. He might see them as a way to not only save Namek but also to restore the Saiyan race. This would open up a whole new set of plotlines and possibilities, as his motives would be different from the other characters who have interacted with the Dragon Balls in the original story.
Well, if a girl from our world is in Inuyasha fanfiction, it really depends on her personality. If she's a brave and head - strong girl, she might join Inuyasha and Kagome on their adventures more actively. She could also be the one to bridge the gap between the feudal era characters and the modern concepts she brings. Maybe she'll try to teach them about things like equality and human rights which could lead to some interesting plot developments.
It could change the story by introducing new skills. For example, if she knows martial arts from the modern world, she could use it against Titans in a different way than the characters in the original story.
Well, if Harry goes back in time, his actions could have a huge impact on the future. For example, if he saves a character who was supposed to die, it could change the entire story. Maybe he saves Cedric Diggory in the Triwizard Tournament earlier than he should have. This could lead to Cedric having a major role in the fight against Voldemort later. Also, if he changes the relationships between characters in the past, like making Snape and Lily closer friends, it could change Snape's attitude towards Harry in the future.
It could strengthen their relationships. If they see positive portrayals of their friendships in the fanfic, it might make them appreciate each other more. For example, if the fanfic shows Aang and Sokka's bromance in a great light, they might feel closer. But if there are negative or inaccurate portrayals, it could cause some tension.
The marauders' presence in 1995 would likely disrupt the normal flow of things. They could influence the relationships between the characters. For example, they might become friends with the Weasley family and introduce some new pranks or ideas to them. Their knowledge of the past could also help in dealing with Voldemort, but it could also create confusion as they may not fully understand the current situation. And they may have some conflicts with certain characters who don't trust their sudden appearance.
Naruto's presence in the past could have far - reaching consequences for the future. His actions to save Kushina could potentially prevent certain events that led to the rise of villains in the original timeline. For example, if the Nine - Tailed Fox attack is thwarted successfully, it might change the circumstances that led to the creation of certain anti - village groups. Also, Naruto could influence the development of new ninja arts in the past, which could then be passed down through the generations and make the village even more powerful in the future.
It could change the power dynamics. Her skills as a kunoichi might be a great addition or a disrupting factor. For example, if she's really strong, she could tip the balance in battles. Maybe she'd team up with Naruto and his friends against a common enemy.
