There are also fanfictions that explore the technology aspect. Since Fallout has a lot of advanced (in a post - apocalyptic way) technology and RWBY has its own Dust - based technology. The Courier could introduce some new concepts to the RWBY world, or be fascinated by the way Dust works. This can be a really cool concept to explore in fanfiction.
I'm not sure if there are a whole lot of these fanfictions, but you might want to check out fanfiction.net. Just search for 'Fallout New Vegas Lone Courier x RWBY' and you'll likely find some. Some might be a bit rough around the edges in terms of writing quality, but there could be some hidden gems.
Another theme is the clash of cultures. The Fallout: New Vegas world has a post - apocalyptic, survival - based culture, while RWBY has a more heroic, fantasy - based culture. In these fanfictions, we often see how the courier's values and ways of doing things contrast with those of the RWBY characters. For example, the courier might be more used to a 'every man for himself' mentality in the wastelands, while the RWBY characters are more about teamwork and heroism. This can lead to some interesting conflicts and growth for the characters.
One great Fallout New Vegas female courier fanfiction is 'The Courier's Journey'. It delves deep into her backstory, like how she came to be a courier in the first place. It has a really engaging plot that involves her interactions with various factions in the game world. Another good one is 'Courier's Redemption'. This one focuses on her moral struggles as she traverses the post - apocalyptic wasteland.
There's a great fanfic called 'Courier Meets RWBY'. In this story, the courier from Fallout: New Vegas somehow finds himself in the RWBY world. It has some really interesting interactions between the courier and the RWBY characters, like Ruby being super curious about his strange weapons and the courier being amazed by the Huntsmen and Huntresses. The story also does a good job of exploring how the courier's skills would translate in the RWBY universe.
Well, I really liked a fanfic called 'Courier's Redemption'. In this story, the OP male courier has to deal with his past mistakes while still being this super capable character. It's got some great character development and interesting plot twists that really draw you in. There are also some really cool action scenes that show off the courier's skills.
The redemption trope can be seen too. Maybe the Courier has some past mistakes or a dark history from Fallout New Vegas, and in the RWBY world, they find a chance to redeem themselves. This can be a really deep and emotional trope, as the Courier tries to become a better person while interacting with the more idealistic characters in RWBY.
Another option is to create a crossover where the essence or abilities of the Courier are transferred to a RWBY character, or vice versa. For instance, a RWBY character could gain the Courier's marksmanship skills. This would change the way they fight and interact with others in their own universe. Or the Courier could gain some semblance - like ability from RWBY, which would give them an edge in the dangerous Fallout world.
One great fanfiction is 'The Courier's Redemption'. It delves deep into the male courier's past and his journey to make amends for his actions. The character development is really well - done, and it adds new layers to the game's lore.
Many fanfictions in this crossover focus on the cultural shock aspect. The Lone Courier comes from a post - apocalyptic world full of mutants, raiders, and survival challenges. When they enter the RWBY universe, which has its own set of rules, cultures, and threats, there are a lot of opportunities for humorous and also thought - provoking interactions as the Courier tries to understand and navigate this new world.
A plot idea could be that the Courier discovers a powerful relic in the Fallout world that has the power to connect different universes. This relic accidentally transports the Courier and some of the key RWBY characters to a strange in - between realm. In this realm, they have to work together to find a way back to their respective worlds while also facing challenges that are a mix of both Fallout and RWBY elements, like Grimm - like creatures with post - apocalyptic mutations and bandits with Dust - powered weapons.
