You could write a fan fiction about a new area in Rapture or Columbia that wasn't explored in the original games. Imagine a hidden section of Rapture filled with advanced technology that was never fully utilized. Or a part of Columbia that has a unique culture or society that we haven't seen before. It could also be interesting to write about a character from the Bioshock world interacting with a character from another game or fictional universe.
One idea could be exploring the backstory of a minor character in the Bioshock universe. For example, a splicer's life before becoming spliced. Maybe they were an ordinary citizen who got caught up in the chaos of Rapture. Another idea is to create an alternate ending for the game, where the protagonist makes a different choice at a crucial moment. This could lead to a completely different outcome for Rapture or Columbia.
One idea could be exploring the backstory of Elizabeth more deeply. Maybe write about her life in the tower before Booker came along. Another could be a story where Booker survives the events of the game and has to deal with the aftermath in Columbia. Or perhaps a fan fiction about different versions of Columbia that exist in parallel universes.
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 idea could be exploring the backstory of a minor character in the Bioshock universe. For example, a splicer's journey before they became spliced. It could show how they were once an ordinary citizen of Rapture and what led them to make the fateful decision to use ADAM. Another plot could focus on an alternate timeline where the protagonist makes different choices. Maybe they side with the wrong faction and have to deal with the consequences. A third idea is a story centered around a new type of plasmid that has unexpected effects on the user and how it impacts the power dynamics in Rapture.
One idea could be a crossover with another game like "The Elder Scrolls". Imagine Booker DeWitt finding himself in the world of Skyrim. He could use his skills and weapons from BioShock Infinite in a completely different fantasy setting, facing off against dragons and magic - using vigors in a new and unexpected way. Another idea might be a crossover with a science - fiction series like "Mass Effect". How would the plasmids and the genetic manipulation in BioShock Infinite interact with the biotics and advanced technology in Mass Effect? It could lead to some really cool battles and character interactions. Also, a crossover with "Alice in Wonderland" could be fascinating. Picture Elizabeth falling down the rabbit hole into Wonderland. Her ability to open tears could have a really interesting impact on the strange and dream - like world of Wonderland, perhaps creating new areas or changing the rules of the land.
One idea could be that a character from another universe gets transported into the BioShock world and has to team up with a Big Daddy. Maybe they start off as enemies, but as they face common threats like the Splicers, they form an unlikely alliance. The Big Daddy could protect the new character while they figure out how to get back to their own world.
Perhaps OC is from the surface world and comes to rescue Elizabeth. Along the way, they have to face the moral dilemmas of the underwater city, like whether to use the power of ADAM or not. This would create a lot of tension and character development as they journey through the dangerous and beautiful but corrupt world of Bioshock.
For tsuperhero fan fiction, you might consider writing a time - travel story. Have a superhero go back in time to prevent a major disaster that changed the course of their world. This could lead to all kinds of interesting plot twists. Another option is to write a story where the superhero loses their powers and has to rely on their wits and the help of ordinary people to get them back. It would be a great way to show the hero's character development outside of just using their powers. And don't forget about writing a story from the villain's perspective, showing their motives and why they do what they do.
Well, you could write a deadpool fan fiction where he accidentally enters the DC universe. Imagine his reactions to all the different heroes and villains there. He might try to make friends with Batman just to annoy him. And he would probably have a field day with the Joker. It could be a really wild and comical story.
One idea could be to explore what would happen if Ross and Rachel didn't have their on - again - off - again relationship but got together smoothly from the start. Another could be a story centered around Joey's acting career taking off in a different way, like getting a major role in a big - budget movie overseas. And also, a fan fiction about Phoebe's past life adventures before she met the gang could be really cool.
One idea could be exploring an alternate universe where Ben gets different aliens. For example, he could have some that are more based on mythical creatures. Another idea is to write about a time when Ben loses his Omnitrix and has to rely on his wits and basic combat skills. It would add a new level of tension and character development.
