The dynamic between the two characters can make it interesting. The female courier is often a strong - willed and resourceful character, while Veronica has her own unique charm and backstory. When their stories intersect in a fanfic, it can create engaging scenarios, like them going on adventures together in the wasteland or sharing their personal stories.
You can start by looking on popular fanfic websites like Archive of Our Own (AO3). It has a large collection of Fallout fanfics, and you can simply search for 'female courier x Veronica' in the search bar. Another option is FanFiction.net, which also has a decent amount of Fallout - related fanfiction. Just be sure to read the tags and summaries to find the ones that suit your taste.
First, they should start as comrades. They meet, recognize each other's skills, and decide to travel together for mutual benefit. For example, the Courier needs someone who knows the area well like Veronica, and Veronica needs the Courier's combat skills. As they face various challenges in the wasteland, like running out of supplies or being attacked by wild creatures, they gradually learn to trust each other more.
A third storyline could be them teaming up to take on a powerful raider gang that has been terrorizing the local settlements. As they plan and execute their attacks, they face challenges that test their relationship and loyalty. This could include moments of doubt and conflict that they have to overcome.
The plot has to be engaging. It might involve the courier's search for a way back home if she's been transported to a different place. Or it could be about her trying to change the new world she's in for the better. There should be enough action, drama, and mystery to keep the readers interested.
A lesser - known but really engaging one is 'Female Courier: Beyond the Wasteland'. Here, the female courier crosses over into a more technologically advanced part of the Fallout world that she's not familiar with. It delves deep into her character development as she struggles to understand and survive in this new area. There are some great plot twists along the way.
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.
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.
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.
A lesser - known but really cool 'Fallout Courier Crossover Fanfiction' is the one that crosses with 'The Elder Scrolls'. Picture the Courier wandering through the provinces of Tamriel. The contrast between the technology - based Fallout world and the magic - filled Elder Scrolls world creates a lot of unique story opportunities, like how the Courier might interact with mages or deal with ancient magical artifacts.
