Survival is a big one. Both Naruto and Fallout worlds have elements of characters having to fight for their lives. In these crossovers, Naruto characters often have to adapt to the harsh post - apocalyptic conditions of Fallout to survive.
Another common theme is power. Naruto characters are known for their unique powers and abilities. In the Fallout setting, these powers are either a great advantage or sometimes a target. It's interesting to see how the power dynamics play out in these crossovers. For example, Naruto's ability to use chakra could be seen as a valuable resource or a threat in the Fallout world filled with mutants and raiders. Also, the theme of finding one's place in a new and strange world is common. Naruto characters are suddenly thrust into a world very different from their own, and they have to figure out where they fit in, whether it's among the different factions in Fallout or just in this new, desolate landscape.
Survival is a big one. Both Resistance and Fallout 4 are set in rather harsh worlds, so in the crossovers, characters often have to fight to stay alive. Another common theme is the clash of different technologies. Resistance has advanced alien - fighting tech while Fallout 4 has its own post - apocalyptic, makeshift tech.
One common theme is the clash of cultures. The high - fantasy society in Elder Scrolls and the post - apocalyptic, often more cynical society in Fallout are very different. Fanfictions often explore how characters from each world react to the other's way of life.
Exploration is also a key theme. In crossovers, new areas and concepts are introduced. In a 'Fallout 4 x Mass Effect' crossover, the vastness of the Mass Effect galaxy is added to the Fallout 4 world. The characters are then driven to explore these new regions, whether it's alien planets in the Mass Effect universe or hidden parts of the wasteland that have been affected by the crossover.
Friendship is a very common theme. Since it's about Naruto and his friends in a crossover, it often shows how their bonds are strengthened or tested in the new situations. For example, they might have to rely on each other more than ever.
A common theme is the clash of cultures. Naruto's ninja culture from his world is very different from the military - and magic - based culture in 'The Gate'. So, exploring how these two cultures interact is often seen. For example, Naruto might introduce the concept of chakra to the people of 'The Gate' world.
Character growth is also a major theme. In a long 'Naruto' crossover fanfiction, Naruto usually has to face new challenges in the crossed - over world. This forces him to adapt and grow in ways he didn't in his original 'Naruto' world. For instance, in a crossover with the 'Fullmetal Alchemist' world, he has to learn about alchemy and its rules, which broadens his understanding and skills.
One common theme is power. The shinju is a powerful entity, and when crossed over with Naruto, it often involves the characters either seeking its power or having to deal with the consequences of its power. For example, in many fics, Naruto might be tempted by the shinju's power to achieve his goals more quickly.
A common theme is the clash and then the fusion of different power systems. Naruto's chakra - based ninja skills and the magic from the other universe, like spells in Harry Potter or magic in Fairy Tail, often start by being at odds but then find a way to work together.
A major theme in these fanfictions is identity struggle. Naruto, being in a chaotic crossover, may question who he is and how he fits into this new, disordered world. Also, the theme of friendship and alliances is quite common. He has to form new alliances with characters from the chaotic world, and these relationships are explored in depth. For instance, he might team up with a chaotic being who has different motives, and they have to work together despite their differences.
One common theme is redemption. Naruto, being banished, often has to prove himself all over again in the new crossovers, seeking redemption for whatever led to his banishment in the first place.
