Character pairings are also a big theme. Some fanfictions might pair characters like Elsa with Dean, exploring how their different personalities and powers interact. There could be a story where Elsa's ice powers are seen as a form of magic that the 'Supernatural' characters have to either understand or combat. It often involves a lot of relationship building and character development within this unique crossover setting.
Another theme is the relationship between Elsa and the other characters in Frozen. For example, how Anna supports her sister during the pregnancy. It can also focus on Elsa's relationship with Kristoff and Sven, and how they adapt to the idea of a pregnant Elsa.
One common theme is the exploration of Elsa's new role as a mother - to - be. It often involves how she deals with the changes in her life and her powers in relation to her pregnancy.
There are also fanfictions that explore Elsa's love in a more modern - day or alternate universe setting. For instance, she could be a college student in a contemporary world and find love in that context. This changes the dynamics of her character and the relationships she forms, making for an interesting read as it combines the essence of Elsa with a completely different backdrop.
Power is also a common theme. The vampire might have certain powers like super strength or mind control, and in the 'Frozen' setting, these powers can either be a great advantage or a hindrance. For example, if they use their powers in front of the wrong people, they could be in danger. There is also often a theme of redemption. The vampire may start out as a bit of an anti - hero but through their experiences in the 'Frozen' world, they start to change for the better.
Another theme is adaptation. Percy has to adapt to the very different world of Frozen, with its different rules, culture, and climate. This often involves him learning about the politics of Arendelle and how to interact with its people while still being true to his own nature.
One common theme is Elsa's self - discovery. She often goes on a journey to understand more about her powers and herself. Another is sisterhood, showing her relationship with Anna in new and different situations. Love is also a theme, whether it's romantic love or love for her kingdom and people.
One common theme is the combination of different types of magic. In these fanfictions, the ice magic of Frozen and the spell - casting magic of Harry Potter often interact. For example, Elsa's power to create ice might be used in a duel against a dark wizard in Hogwarts. Another theme is friendship. Just as Harry, Ron and Hermione have a strong bond, the characters from Frozen also value friendship, and in the fanfictions, they often come together to face challenges. For instance, Anna might team up with Hermione to solve a mystery.
A common theme is also about acceptance. The people of Arendelle need to accept the fact that their queen is going to be a mother. And Elsa herself has to accept the changes in her body and life. In addition, the theme of love is often present. Whether it's the love for her unborn child or the love from her friends and family during this time.
One common theme is the struggle of the frozen fox to fit in. Since it's a unique creature in the Naruto universe, it often has to deal with being different from the regular ninjas and villagers.
One common theme could be the discovery of new powers or abilities during the chance encounter. For example, a character might find out they can control a new type of magic.
