One popular theme is the combination of different kinds of magic. The ice magic from Frozen and the dragon - related magic in HTTYD. Another theme could be friendship across different worlds. Characters from HTTYD like Hiccup and those from Frozen like Anna forming an unlikely alliance. Also, the theme of discovery, as the characters from one world discover the wonders of the other world.
In httyd frozen crossover fanfiction, a frequently seen theme is the clash and then the harmony of two different cultures. The Viking - like culture in HTTYD and the more European - inspired culture in Frozen. Another popular theme is environmental protection. The dragons in HTTYD are closely related to nature, and Elsa's ice powers also have an impact on the environment. So, the characters might team up to protect a shared environment. Additionally, the theme of self - growth is present. As the characters face new challenges in the crossover, they learn and grow, like Hiccup learning more about magic from Elsa and Elsa learning about courage from Hiccup.
The idea of being different and having to find one's place in the world is also present in both. A fanfiction could explore how Elsa, with her ice powers, and Hiccup, with his connection to dragons, both feel like outsiders in their own communities at first. They could come together and help each other realize that their differences are actually their strengths. This could involve them teaching their respective communities about acceptance and the value of being unique.
In some fanfictions, Hiccup and Anna might team up. Hiccup's knowledge of dragons and Anna's adventurous spirit could lead them on a quest. They might encounter a new type of dragon that has been affected by Elsa's magic, and they have to figure out how to deal with it while also trying to get Elsa and Toothless to work together.
First, you need to study the characters and settings of both 'How to Train Your Dragon' (HTTYD) and 'Frozen' well. For example, understand Toothless's character traits in HTTYD and Elsa's in Frozen. Then, think of an interesting plot that can combine the two worlds. It could be about a quest where the characters from both universes have to team up to face a common threat. Also, pay attention to the writing style, keep it engaging and easy to follow.
One idea could be that the dragons in HTTYD are attracted to the cold of Frozen's world and they fly there. The people of Arendelle are initially scared but then they learn about the dragons from the dragon riders. Another idea is that Elsa's ice powers somehow have an effect on the dragons, like making their fire breath turn into ice breath for a short time.
First, you need to understand the characters and worlds of both HTTYD and Frozen. Then, think of an interesting plot that can bring the two together, like maybe a dragon from HTTYD somehow ends up in the Frozen world. Next, start writing the story, focusing on how the characters from both universes interact with each other.
One popular idea is a httyd and How to Train Your Knight crossover. Imagine the dragons in a world filled with knights and castles. Another could be a crossover with a modern - day setting, like httyd characters in a big city dealing with new challenges. And there's also the idea of a crossover with a fantasy world like Middle - earth, where the dragons interact with different magical creatures.
One popular trope is the 'fish out of water' situation. For example, a character from HTTYD finding themselves in the world of HOO and being completely confused by the Greek gods and demigods. Another is the 'team - up' trope, where the dragon riders and the demigods join forces to defeat a powerful enemy. A third one could be the 'culture clash' trope, with the Vikings from HTTYD having different values and ways of life compared to the modern - day (sort of) world of HOO.
Adventure is also a very common theme. Writers like to send the characters from both universes on quests or to face new and dangerous enemies. For example, they might have to battle a powerful dark force that is a threat to both the troll world and the world of dragons and Vikings. This allows for a lot of action - packed scenes and exploration of new terrains in the fanfiction.
There are often crossovers with other fantasy universes. For example, in some 'httyd crossover fanfic', the Vikings from httyd meet the characters from 'Narnia'. The contrast between the two worlds, one with dragons and the other with magical creatures like centaurs and fauns, makes for a really engaging story. It can bring new adventures and challenges for the httyd characters.
One great 'frozen watches httyd fanfiction' could be the one where the characters from Frozen are transported to the How to Train Your Dragon world and they have to learn to ride dragons. It's really interesting to see how Elsa's powers interact with the dragons.
