Survival is a very common theme. Since Fallout 4 is set in a post - apocalyptic world, many fanfictions focus on how the reader character survives the harsh conditions, like finding food, water, and shelter.
Friendship is a very common theme. Their relationship, whether it's starting as rivals or comrades, often develops into a deep and meaningful friendship. Another theme is growth. They both grow as characters through their interactions with each other.
Their relationship could develop through shared adventures. For instance, when they go on a mission to retrieve a valuable item from a raider - held location. During this time, Naruto protects Piper with his powerful jutsu, and Piper uses her wits and knowledge of the wasteland to guide them. This mutual reliance will strengthen their bond and lead to a deeper understanding of each other.
One popular 'Ao no Exorcist Shura x Yukio' fanfic is 'Bond of Shadows'. It delves deep into their complex relationship, exploring how Shura's tough exterior softens around Yukio. Another great one is 'Unspoken Ties' which focuses on their shared experiences in the exorcist world and how it brings them closer. There's also 'A Different Kind of Bond' that shows their relationship evolving in a unique way as they face various challenges together.
One common theme is adventure. Since Eureka Seven AO is set in a rather adventurous world, the fanfics often involve the reader going on exciting adventures with AO. Another theme is friendship and loyalty, as they face challenges together and rely on each other.
A more complex plot might be that Naruto's presence in the Fallout 4 world starts to change the balance of power. His positive energy and strong will begin to inspire the people in Piper's settlement. Meanwhile, Piper helps Naruto understand the political and social dynamics of the wasteland, and together they try to bring peace and unity among the different factions.
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 great 'fallout 4 x reader fanfiction' is 'A New Beginning in the Wasteland'. It has an engaging plot where the reader character teams up with the Sole Survivor to rebuild a settlement. The character development is really well - done, making it a great read.
