One interesting concept could be exploring the backstories of the Whos in more detail. For example, how they built their unique houses or what their family traditions are.
Another aspect might be creating new adventures for the Whos. Maybe they go on a journey to a far - off land within the Whoville world and encounter strange creatures. In some fan fictions, the Whos could also have to deal with a new villain that threatens their happy little town.
Some fan fictions might focus on the relationships between the different Whos. For instance, exploring the friendship between Cindy - Lou Who and other characters in more depth. It could also look at how they support each other during difficult times, like when there are shortages of holiday treats or when a big storm hits Whoville.
Love and friendship are often big themes. You'll see characters forming deep bonds and overcoming obstacles together.
Cindy - Lou Who is also popular. She is seen as a symbol of innocence in the Whoville world, and fan fictions may show her growing up and facing new challenges while still maintaining her kind heart.
One interesting concept could be alternate storylines for the characters. For example, exploring what would happen if Bell Cranel had a different Familia. It could lead to completely new adventures and character developments.
One interesting concept could be the exploration of uncharted regions in Morrowind that were only hinted at in the original game. Fan fiction might describe these areas in great detail, like hidden underground caverns filled with ancient Dwemer machinery. Another concept could be the backstories of minor characters, giving them more depth and significance. For example, a fanfic could focus on the life of a common Redguard fisherman in Morrowind and how the events of the game world impact him.
One interesting concept is the exploration of new Titan models. Fan fiction often imagines Titans with unique abilities or designs. For example, a Titan with the power to cloak itself and its pilot, allowing for stealthy attacks. Another concept could be different backstories for the Pilots. Maybe a Pilot who was once a criminal but is now fighting for redemption in the Titanfall battles. There are also ideas about new game modes within the Titanfall universe in fan fiction, like a survival mode where Pilots have to fend off waves of enemy Titans and infantry without any reinforcements.
One interesting concept could be alternate endings for the game's story. Maybe in the fan fiction, the main character makes different choices that lead to a completely new outcome for Rapture. Another concept could be exploring the backstories of minor characters in more depth, like the splicers, and how they came to be in their current state.
One interesting concept could be alternate character backstories. For example, in Apocrypha fan fiction, a writer might explore what led a minor character to have the motives they do in the original work. This can add depth to the overall narrative.
One interesting concept could be alternative universes. For example, a DWP fan fiction might explore what would happen if the main characters had different powers or origins. Another concept could be character relationships. Writers might develop deeper friendships or unexpected romances between characters that are not as emphasized in the original DWP. Also, time - travel is a popular concept. It can be used to change past events in the DWP world and see how it affects the overall story and characters.
One interesting concept could be the discovery of new supernatural abilities. For example, a character might find they can control time in a unique way that's different from the usual time - control tropes. Another could be the discovery of a hidden supernatural realm that has its own set of rules and creatures.
One interesting concept could be alternate universes where the characters have different fates. For example, Mal could have become a successful Alliance officer instead of a rebel. Another might be relationships that develop differently, like a deeper romantic connection between Kaylee and Simon earlier in the story. And then there are concepts where new characters are introduced that change the whole dynamic of the Serenity crew.
