Well, they can be created in various ways. Some authors create them by changing a single key event in the original story. For example, if in the original a character made a certain choice that led to a particular outcome, in the alternate universe, they make a different choice. Others might create an alternate universe by changing the setting, like making a modern - day story take place in a fantasy world instead. It really depends on the creativity of the fan fiction writer.
One popular theme is role reversals. For example, in a superhero alternate universe fan fiction, the villain could be the hero and vice versa. Another theme is different time periods. Fans might write about their favorite characters in a historical setting. Also, gender - swapped versions of characters are common.
One popular type is the 'gender - swapped' alternate universe. In this, the genders of the main characters are swapped while keeping their personalities and storylines somewhat similar. Another is the 'vampire/werewolf' alternate universe, especially in stories that originally don't have such supernatural elements. It adds a new layer of mystery and danger. And then there's the 'historical re - imagining' alternate universe, where a modern story is set in a different historical period, like a superhero story set in the Middle Ages.
First, choose the original work you want to base it on. Then, think of one big change you want to make to the universe, like a different law of physics or a major event that didn't happen in the original. After that, start developing your characters based on how they would be affected by this change.
Well, alternate history fiction basically takes real historical events and changes one or more key elements to create a new fictional narrative. It allows us to think about all the possible 'what ifs' in history.
Qui - Gon Jinn is often a popular character in these fan fictions. His maverick ways within the Jedi Order make him an interesting subject for alternate storylines. Writers might explore what would have happened if he had survived longer and continued to mentor Obi - Wan and Anakin.
In my opinion, the alternate universes in the 'Spider - Verse' are fascinating. Seeing all those different versions of Spider - Man from various universes coming together was amazing. Each Spider - Man had his own unique style, powers, and backstory. Also, the Narnia universe is very interesting. The way it has different seasons and a talking animal population makes it a really magical and different place compared to our world.
In alternate Americas in science fiction, technology can also take a very different path. There could be a world where steam - powered technology dominates instead of electricity. This would change the look of cities, with large steam - powered factories and vehicles everywhere. It would also affect the way people live and work, as steam - based technology might be less efficient in some ways but could create a more industrial - age aesthetic.
Yes, in a sense. Alternate reality often involves concepts that go beyond our current understanding of the real world, which are typical in science fiction. It allows for the exploration of different universes, timelines, and possibilities that we don't experience in our day - to - day lives.
Another plot could be a different take on the fall of Anakin Skywalker. Instead of Palpatine's manipulation being the sole factor, there could be an ancient Sith artifact that influenced him. This would add a new layer of mystery and a different origin for his turn to the dark side.
