One interesting concept is the re - imagining of well - known characters in different settings. For example, taking a classic fairy - tale character and placing them in a modern, post - apocalyptic alternate world. Another concept could be the creation of entirely new species or races that are unique to the alternate world. Also, exploring different social structures and power dynamics in these worlds can be really engaging.
Well, in alternate worlds fanfic, the idea of magic systems is quite fascinating. Some fanfics develop complex and unique magic systems that are different from the traditional ones. And time - travel concepts are also common. It allows the characters to move between different time periods in the alternate world, which can lead to all kinds of interesting plot twists. Then there's the concept of parallel universes where slight differences in choices create vastly different worlds.
One interesting concept could be a world where the South won the American Civil War. This would lead to a completely different social, political and economic landscape in the United States. Another could be if the Roman Empire never fell and continued to expand and influence the modern world in ways we can't even imagine. Also, the idea of a world where dinosaurs never went extinct and co - exist with humans is really fascinating in alternate history fanfic.
In War of the Worlds fanfic, a common concept is the survival of the individual in the chaos. Some stories focus on a single character's journey through the desolate, war - torn landscape. They might have to scavenge for resources, avoid both alien and human threats. Also, the idea of the aliens having a weakness that is not in the original story is often explored. Maybe it's a certain frequency of sound or a type of plant that can harm them. This gives the humans a glimmer of hope in an otherwise hopeless situation.
One interesting concept is the re - imagining of characters. For example, in an alternate universe, a classic hero could be a villain. Another concept is the different power structures. Maybe magic is used in a completely new way, like being a currency instead of a weapon. Also, the alternate social hierarchies can be fascinating. A race that was once oppressed could be the ruling class.
One interesting concept is the idea of meeting alternate versions of oneself. It can lead to self - discovery and exploring different personalities. Another is the discovery of unique cultures and societies in the alternate universes. For example, a world where magic is the norm instead of science. And then there's the concept of changing the course of events in an alternate universe, which can have far - reaching consequences.
One interesting concept could be a Naruto AU where the main characters have different elemental affinities. For example, Naruto might be a water - type user instead of wind. Another concept could be a world where the Akatsuki are the heroes. They could be fighting against an oppressive regime that the Hidden Villages support. Also, a fanfic could explore a Naruto AU where the tailed beasts are free and coexist peacefully with humans from the start.
One interesting concept could be a different political landscape. For example, if the Reds had achieved certain goals earlier or in a different way. It might also explore how different leaders could have emerged and changed the course of events. Maybe there could be a scenario where the Reds had more influence on international relations at an earlier stage, leading to different alliances and geopolitical situations.
Well, in Star Wars alternate universe fanfic, a cool concept is the existence of Force - sensitive species that were never mentioned in the original canon. Maybe there's a species that can manipulate the Force in ways that are completely different from Jedi or Sith, like being able to use it to communicate with all forms of life on a planet simultaneously. Another interesting thing could be a story where the Galactic Empire never fell, but instead evolved into a more benevolent regime over time due to some internal reforms. And then there are fanfics that explore what would happen if a character like Han Solo was a Jedi from the start, which would change a whole lot of the storylines we know.
One interesting concept could be alternate versions of the main characters' relationships. For example, in the regular universe, Kirk and Spock might have a certain dynamic, but in the alternate universe fanfic, they could be rivals or have a completely different friendship. Another concept might be different technological developments. Maybe in this alternate universe, the Federation has developed a new type of warp drive that allows for instantaneous travel. Also, there could be changes in the political landscape of the Star Trek universe. Instead of the Federation being a dominant force for peace, it could be at war with other species more often.
Well, in some Harry Potter alternate reality fanfics, the houses at Hogwarts are sorted differently. For example, instead of the Sorting Hat choosing based on certain traits, students are sorted randomly. This completely changes the social structure within the school. Also, there are fanfics where magic works in a different way. Maybe spells require a different type of wand movement or incantation. It makes for a really fresh take on the magic we know from the original books.
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.
