The theme of redemption can also be found. Maybe a character from The Last of Us who has done some bad things in their own world tries to find redemption in the wizarding world. Or vice versa, a dark wizard from Harry Potter might see the value of life more in a post - apocalyptic world like The Last of Us and change their ways. There's also the exploration of new worlds, as the two very different universes collide and create unique settings for the stories.
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.
One common theme is the power of friendship. In both 'Harry Potter' and 'The Last Airbender', the main characters rely on their friends. So in fanfiction, this is often explored further. Another is the battle between good and evil.
Survival is a very common theme. Since the main character is the last human, they have to find ways to stay alive in a world that is either empty or full of danger. For example, in many of these fanfics, Harry has to figure out how to get food and shelter without the support of the wizarding community as it once was.
Another common theme is regret. Maybe a character realizes too late how much they love another, and the 'last kiss' is a bittersweet moment filled with all the things they should have said or done. In some fanfictions, it can also be about sacrifice, where a character gives up their relationship for the greater good, and that 'last kiss' is a symbol of their selfless act.
A common theme in such fanfiction could be the exploration of different forms of magic. Gods would likely bring with them magic that is far more powerful and different from what the wizards are used to. There could also be a theme of alliances and rivalries. Some wizards might side with certain gods, while others oppose them. And finally, the theme of the balance of power. How does the wizarding world maintain its balance when these all - powerful gods are present? It could lead to a struggle for power and control within the story.
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 clash of different cultures. For example, the wizarding culture in Harry Potter and the diverse cultures in Avatar. Another theme is the discovery of new powers. Characters from one universe might discover the abilities of the other universe, like a Hogwarts student learning bending.
One idea could be a crossover where the magic from Harry Potter is used to combat the infected in The Last of Us world. For example, the Patronus charm could be used to repel the Clickers as it is a powerful form of positive magic. Another could be that some of the characters from The Last of Us are transported to the Hogwarts world and have to learn magic to survive in this new and strange place. They could be sorted into houses based on their personalities.
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.
