They would find themselves in a world full of historical events in progress. If they were in a military - significant area, they could potentially change the course of history, even accidentally. For instance, if they gave away some modern military strategies or information about future technology, it could have a big impact on the outcome of battles. Also, they would have to adapt to the lack of modern conveniences like smartphones and the Internet, and deal with the rationing and shortages that were common during WW2.
If someone went through it, they would likely face a huge culture shock. The language, the way of life, and the values in WW2 were very different from today. They might also be in danger, as WW2 was a time of war with battles and bombings everywhere. For example, if they landed in a war - torn city, they would have to quickly find shelter and figure out how to survive.
It could be due to a strange natural phenomenon. There are theories about certain areas on Earth having abnormal magnetic fields or gravitational anomalies that could potentially create a portal through time. In the context of a modern - day story, perhaps a group of scientists discovers such an area while doing research. They unknowingly step into a portal that takes them back to WW2. This would be a really exciting and unexpected turn of events in the story.
In such a fanfiction, one possible outcome could be a character using knowledge from WW2 to change the course of WW1. For example, they might introduce more advanced military tactics. Maybe they could try to prevent certain events that led to the large - scale destruction in WW1. However, this would also likely cause a lot of chaos as the timeline is disrupted.
Well, he might use magic to create the most amazing pastries. His Firebolt skills could translate to lightning - fast kneading of dough. And his Hogwarts friends would surely visit often, like Hermione might help with the bookkeeping using her intelligence and Ron would be there to taste - test everything.
In fanfiction, if Naruto were to open the gate of death, he might gain an extreme power boost. This could potentially allow him to defeat enemies that were previously unbeatable. However, it would likely come at a great cost, perhaps his own life or a part of his soul.
In an Opposite Day story, night would become day and day would become night. Cold things would be hot and hot things cold. For example, ice would be burning and fire would be freezing.
Well, they could change the course of the war. For example, Iron Man could use his advanced tech to quickly take out enemy tanks. Captain America would feel right at home in a way, fighting alongside soldiers again. And Thor could use his lightning powers to disrupt enemy lines.
Oh, it could be a real disaster! Maybe the main character misses all their important appointments, has their car break down, and then loses their job.
They would likely face serious consequences. Firstly, they would draw a lot of unwanted attention and shock from people on the street. Secondly, the police might be called due to public indecency, and they could be arrested or at least given a stern warning. Their school would also take disciplinary action against them.
In Xianxia novels, Qi deviation usually referred to the character in the novel losing control of his mind due to excessive indulgence in cultivation, combat, or other things. In this state, the character might lose his mind and do something immoral or dangerous. Qi deviation was usually a serious consequence. It could cause the character to lose control of himself or even hurt himself or others. In addition, Qi deviation could also cause the character's cultivation to decrease and they could not continue cultivating or fighting, thus losing their advantage. In novels, Qi deviation was usually a terrifying scene that made the readers nervous and afraid. Therefore, when reading Xianxia novels, it was recommended that readers should maintain their rationality and not be overly addicted to the plot in the novel to avoid unnecessary danger.
Well, it would be a wild ride. Merlin's old magic and wisdom would clash with contemporary society, causing chaos and maybe some opportunities for him to use his powers in new ways. There could also be people who try to exploit or study him.
