A Fallout 4 fanfic could be about a lone wanderer who stumbles upon an ancient vault that has been untouched since the war. Inside, they find strange and powerful technology that could change the balance of power in the wasteland. However, they also face numerous traps and challenges within the vault. This would lead to a story of discovery, danger, and decision - making as the character decides what to do with their newfound discovery.
One idea could be to focus on a character who is a pre - war scientist awakened in the post - apocalyptic world. They could use their scientific knowledge in unexpected ways to survive and perhaps try to rebuild some aspects of pre - war technology. Another interesting angle is to write about a group of settlers trying to establish a new community in an area filled with dangerous creatures. They would have to deal with not only the external threats but also internal conflicts within the group.
You could write a fanfic about the origin of one of the factions in Fallout New Vegas. Let's say the Powder Gangers. Maybe they were once just a group of miners who were mistreated and decided to take up arms. Show how their ideology evolved from a simple quest for justice to the more chaotic and violent group we see in the game.
One plot idea could be that Elsa from Frozen somehow ends up in the Fallout wasteland. Her ice powers could be both a hindrance and a help. For example, she could use her ice to create shelters in the harsh environment, but her powers might also attract unwanted attention from raiders or mutants. Another idea is that the Brotherhood of Steel discovers Elsa and tries to study her powers, thinking it could be some sort of advanced technology. A third plot could involve Anna coming to the Fallout world to find Elsa and they team up with some of the more friendly factions in the game to survive and try to find a way back home.
One idea could be that the RWBY characters find themselves in the Fallout wasteland. Ruby could use her Crescent Rose to fend off mutants. Weiss might struggle with the harsh and dirty environment compared to her usual clean Atlesian surroundings. Blake could use her stealth skills to navigate dangerous areas, and Yang's strength would be useful in combat against raiders. They could be on a quest to find a way back to their own world while also trying to make the wasteland a better place.
One plot idea could be that Finn and Jake from Adventure Time end up in the Fallout wasteland. Finn, with his sword skills, could be on a quest to find a special artifact to get back to their own world. Jake, with his shape - shifting abilities, might help them survive against the various mutated creatures in the Fallout universe. Another idea is that the Vault - Tec technology in Fallout somehow merges with the magical elements of Adventure Time, creating strange new hybrids of mutants and magical beings.
One idea could be an OC who is a brilliant scientist in the Fallout world. They could be working on a secret project to reverse the effects of radiation. Another idea is an OC who is a wandering trader, having all kinds of adventures while traveling from one settlement to another, facing raiders and mutants along the way. And a third idea could be an OC that is part of a new faction trying to bring peace and order to the wasteland.
One idea could be a story where the protagonist, a lone wanderer, gradually gathers a diverse group of female companions from different factions in the Fallout world. For example, a Brotherhood of Steel scribe, a raider who has a change of heart, and a super mutant with a unique personality. Their relationships could develop as they face various threats together, like fighting off hordes of feral ghouls or taking on powerful raider gangs.
One idea could be a crossover where characters from Fallout enter the RWBY universe. For example, a Vault Dweller could end up in Vale and have to adapt to the Grimm - filled world while also trying to find a way back home. Another could be a story where RWBY characters are thrown into a post - apocalyptic setting like in Fallout, dealing with radiation and mutated creatures.
Well, you might consider writing a fan fic about a group of survivors who are trying to rebuild a small community in Fallout 76. They have to deal with raiders, lack of resources, and the ever - present threat of radiation. Or perhaps a story about a character who discovers an ancient technology that could change the fate of the wasteland but has to keep it a secret from those who would use it for evil. And then there's the idea of a fan fiction based on the relationships between different characters, like friendships or rivalries.
One idea could be exploring the backstory of a minor character in the game. For example, the merchant who sells you those rare weapons. You could create a whole story about how they came to be in the wasteland and how they got their hands on those precious items.
One interesting storyline could be about a group of survivors trying to rebuild a community in the post - apocalyptic world of Fallout. They might face challenges like raider attacks and resource shortages.
