In the sentinel fanfiction, an interesting concept is the world - building. Authors often create a universe where Sentinels and Guides are part of a society that has its own rules and hierarchies. There could be a whole system of training for Sentinels and Guides, and fanfiction may explore how this system works. Also, the relationship between Sentinels and Guides can be seen in different ways, like some stories might focus on the romantic aspect, while others on the platonic or a more mentor - mentee type of bond.
One interesting concept could be the combination of the Sentinel's unique abilities with the technology and settings of Stargate. For example, how the Sentinel's heightened senses might interact with the alien technologies in the Stargate universe. Another could be the character crossovers, like how the Sentinel characters might fit into the existing Stargate teams and their dynamics.
One idea could be a crossover with a superhero universe. The Sentinel could team up with well - known superheroes to fight a common enemy. For example, joining forces with Superman to stop an alien invasion that threatens both their worlds.
There are often fanfictions that blend the Sentinel concept with Harry's connection to Voldemort. Maybe in a story, Harry's Sentinel powers are enhanced because of his link to the Dark Lord. This could lead to a series of battles where Harry has an edge due to his ability to sense danger and threats in a different way compared to normal wizarding abilities. It could also add a new layer to his relationship with his friends, as they have to adjust to this new aspect of Harry.
One idea could be that the Stargate team discovers a world where the Sentinel abilities are a natural part of the population. The Sentinels' powers could be used to help the Stargate team in their exploration and battles against alien threats. For example, their enhanced senses could detect hidden Goa'uld symbiotes or hidden traps in ancient ruins.
A plotline could be Sentinel Prime getting corrupted by dark energy and Optimus Prime having to fight him to bring him back to the light. It would be a battle of wills and also a test of their long - standing friendship.
Another concept might be alternate universes. Maybe a Zootopia where predators and prey have completely different social dynamics. They could be living in a more equal yet chaotic world where the roles are not as clearly defined as in the original movie.
Well, in prey fanfiction, a cool concept is the creation of new powers or abilities for the characters. For example, the protagonist could gain some sort of psychic ability related to the alien technology. Some fanfics also delve into the idea of different endings to the Prey story, like a more positive or more tragic end compared to the original. And then there's the concept of crossovers, where Prey characters interact with characters from other science - fiction universes.
In ppg fanfiction, a cool concept is the idea of the Powerpuff Girls forming alliances with other characters from different shows or universes. This could lead to some really exciting crossovers and new storylines. Also, some fanfictions might focus on the origin story of the villains in the Powerpuff Girls world, like how Mojo Jojo became the way he is. And there could be fanfictions that explore the relationship between the Powerpuff Girls and their creator, Professor Utonium, in more depth, like how they feel about being created in a lab.
One interesting concept could be exploring the moral dilemmas that characters face during the purge. For example, a character might have to decide whether to save a stranger or protect their own family. Another concept could be how different social classes experience the purge. The rich might have more resources to protect themselves, while the poor are more vulnerable.
One interesting concept could be alternate universes where the slendytubbies have different powers or characteristics. For example, they might be able to communicate with humans in a friendly way instead of being menacing.
