One common theme is survival. Just like in The Last of Us, the characters often have to fight for their lives in a harsh environment. And Naruto characters bring their own skills to aid in this survival.
Some common themes could be Naruto characters adapting to the US Army's discipline. For example, Naruto's determination in the Naruto world might translate to his eagerness to succeed in military training. Another theme could be teamwork. In Naruto, teamwork among the ninja squads is crucial, and in a US Army - Naruto fanfic, it could be about how Naruto and his friends from the series work together with US Army soldiers on missions. Also, there might be a theme of cultural clash, as the ninja culture from Naruto meets the military culture of the US Army.
The theme of redemption is quite prevalent. OCs might have made mistakes in their pasts and are now trying to make up for them in the world of 'The Last of Us'. Also, the idea of adapting to a changed world is common. These OCs have to learn new skills and ways of life in a world overrun by infected. They might start as city - dwellers and have to quickly learn how to survive in the wilderness.
Survival is a very common theme. Given the post - apocalyptic setting of 'The Last of Us', many fanfictions focus on how characters endure and overcome the various threats in this new world. Another common theme is the relationship between characters, especially the bond between Joel and Ellie. Writers often explore different facets of their relationship, like moments of trust - building or potential conflicts. Also, the theme of hope in a desolate world is prevalent, as fans write about characters finding reasons to keep going despite the odds.
One common theme is the combination of different powers. Since both Naruto and Avatar have their own unique power systems, fanfics often explore how these powers can work together or against each other. For example, a character might try to use chakra to enhance their bending ability.
One common theme is the combination of powers. Fans often like to see how the bending abilities from Avatar would mix with the ninja techniques in Naruto. For example, how would waterbending work with water - based jutsu? Another theme is the clash of cultures. The two universes have very different cultures, and exploring how they interact can be really interesting.
One common theme is power. In both Naruto and Avatar, power plays a huge role. So in the fanfics, it's often about characters from both universes either comparing their powers, or finding new ways to combine them. For example, Naruto's chakra control might be related to an Avatar's bending control.
Romance is also quite common. Fans might pair up characters from both universes in different romantic relationships. And of course, there are often themes of friendship and loyalty, as these are important aspects in both RWBY and The Last of Us. The characters from both are often put into situations where they have to rely on their friends and show loyalty to one another.
One common theme is self - discovery. The male OCs usually start with a certain view of themselves and the world, but through their experiences in the 'The Last of Us' universe, they change and grow. Also, the theme of sacrifice often appears. They might have to sacrifice something for the greater good.
One common theme is survival. Since the game is set in a post - apocalyptic world, the OC often has to struggle to survive alongside Joel. They face infected and other hostile humans.
A common theme is survival. Just as in The Last of Us, survival is key. In these fanfictions, the characters from both universes have to find ways to stay alive, whether it's from the infected in The Last of Us or from dark wizards in Harry Potter. Another theme is adaptation. Characters like Ellie or Joel have to adapt to the magical world, and Harry Potter characters might have to adapt to a more post - apocalyptic situation.
