In developing the characters, Iceland could be seen as a proud and strong entity. It has its own traditions and values. The fridge could be developed as a misfit, not fitting into the normal world of appliances. When they meet, Iceland might initially be skeptical of the fridge. But as the fridge shows its unique abilities, like being able to create a mini - ice age in a small area, Iceland starts to respect it. Their relationship could be built on mutual discovery and acceptance.
The character of Iceland could be developed as a wise old being, having seen centuries of changes. It can be a bit aloof at first but warms up (ironically) to the fridge. The fridge could be a new - comer to this world, full of energy and questions. As the story unfolds, the fridge's inquisitive nature could draw out the more talkative side of Iceland. And their interactions could be based on the fridge's need for a place to belong and Iceland's need for some new - found purpose.
For the character of Iceland, it could be personified as a guardian of cold. It might have a reserved personality, much like the country's natural solitude. The fridge, on the other hand, could be developed as a curious entity. Maybe it has a child - like eagerness to explore the world outside its cold interior. They could start as strangers but gradually form a bond as the story progresses.
In this fanfiction, the fridge could be a portal to another dimension where Iceland is the key to open it. Every time the fridge door is opened in a certain way while in Iceland, it reveals a different world. The story could follow a group of adventurers who try to figure out the mystery of the fridge - Iceland connection and what lies beyond the portal. They might face challenges in Iceland's harsh environment while trying to unlock the secrets of the fridge.
I don't think there's a direct connection. Iceland is a place, a fridge is for storage of food, and a comic is for entertainment or storytelling. Maybe in a strange dream or a unique art project they could come together, but that would be quite unusual.
One possible theme could be the idea of Iceland's relationship with a domestic object like the fridge. It might be about how the fridge represents a source of comfort or stability for Iceland. For example, the fridge always having food available during Iceland's long, cold winters.

Since I don't know the exact story, it's difficult to say who the characters are. But it could be an ordinary person, like a man or a woman who is in a tough situation related to the fridge.
In fanfiction, Percy and Hermione's characters can be developed in various ways. Some writers might explore Percy's sense of duty and how it interacts with Hermione's thirst for knowledge. For example, they could be on a mission together where Percy's strategic planning, which he learned from his time in the Ministry, combines with Hermione's research skills to solve a complex magical problem.
They are often developed by exploring new relationships. For example, the bond between Bella and her new vampire family members can be deepened or changed in fanfiction. Sometimes, characters are developed by giving them new powers or abilities that were not in the original story.
Character development can also involve giving backstories to minor characters. For instance, a random demigod in the fanfiction could have a tragic past that led them to the Labyrinth battles. This not only fleshes out that individual character but also adds depth to the overall story. And for the main characters, their flaws could be explored more. Percy's impulsiveness could lead to more serious consequences in some fanfictions, forcing him to learn and grow from those experiences.
Friendship or a deeper relationship is another theme. Many stories depict them as friends who have a special bond, or in some cases, a romantic relationship. They might go on adventures together, sharing their love for the northern landscapes and traditions. For example, they could go skiing in the Norwegian mountains or explore Iceland's geothermal areas together. It's all about their connection and how it grows.
A common theme is family - like relationships. Given their historical and cultural connections, many fanfictions depict them as having a sort of brotherly bond, with Norway being the older, more experienced one and Iceland as the younger, more curious one.
