Often, themes of self - discovery are present. Both Jack Frost and Jamie might be on a journey to understand their feelings for each other and their own identities within the relationship. Another theme could be the power of their bond, how they support each other through difficulties whether they are related to their powers (if they have any in the original context) or just personal issues.
One common theme could be the exploration of their relationship in a new and different setting than the original source. Maybe they are in a modern AU (alternate universe) where they have to deal with normal life problems while also being in a relationship.
Yes, there might be some out there. You can start by looking on fanfic websites like Archive of Our Own. They usually have a wide range of fanfictions including yaoi ones. Just search for 'jack frost x jamie' in their search bar and you'll likely find several stories.
One common theme could be the exploration of an unusual relationship dynamic. Since Jack Frost is often portrayed as an immortal or otherworldly being and Jamie is older, it might deal with how they bridge the gap between their different existences. Another theme could be the idea of finding love in unexpected places. For example, their relationship might start from a series of chance encounters that gradually develop into something more. Also, a theme of growth and change could be present. As Jamie is older, he may have different life experiences that Jack Frost can learn from, and vice versa, leading to personal development for both characters in the fanfic.
One common theme is friendship. Their bond as a human and a magical being is often explored. Another is growth, like Jamie's growth in understanding the magical world because of Jack. Also, adventure, as they might go on various adventures together in the stories.
Belonging is another important theme. Jack, who is often seen as an outcast in the spirit world, finds a sense of belonging with Jamie. And for Jamie, he feels like he belongs to a more magical and special world when he is with Jack. This mutual feeling of belonging strengthens their relationship and is a key aspect in many of the fanfictions about them.
One common theme could be the exploration of their different personalities. Jack Frost is often seen as more carefree and mischievous, while Bunnymund is more grounded. Their relationship in the fanfiction might play on how they balance each other out.
The contrast between them. Jack is otherworldly and cold, while Jamie is human and warm. This creates an interesting dynamic.
One common theme is friendship. Since Jamie can see Jack Frost in the original story, a female Jack Frost could form a unique friendship with Jamie. They might go on adventures together in the winter wonderland.
One example could be a story where Jack Frost and Jamie share a magical adventure together. In this fic, their relationship might start as a friendship that gradually develops into something deeper. They could face challenges like a powerful winter spirit trying to disrupt the peace, and through their bond, they overcome it.
A common theme is the contrast between their elements. Sandman with his sand representing dreams and Jack Frost with his ice symbolizing cold and winter. This contrast often leads to interesting power dynamics in the stories.
Adventure is also quite common. Combining the icy world of Jack Frost and the dragon - ridden world of Hiccup, there are often epic quests and challenges they face together. Their unique abilities help them overcome obstacles in these adventures.
