In this fanfiction, Elsa and Jack Frost are the main characters. Elsa is a complex character, initially feared in her own kingdom because of her powers. Jack Frost, on the other hand, is a more free - spirited character who loves to play with children and spread winter magic. Their meeting in the fanfiction likely brings out new aspects of their personalities as they interact.
One possible plot could be that Jack Frost, being the spirit of winter himself, is intrigued by Elsa's ice powers. They could start by having a friendly competition to see who can create the most magnificent ice sculptures. Their powers combined might accidentally create a new, magical ice realm that they then have to explore and protect together from an approaching threat, like a dark sorcerer who wants to steal their ice magic.
Their interaction could be really magical. Elsa, with her ice powers, and Jack Frost, who is also associated with ice and winter, might start by being cautious around each other. Maybe they'd compare their powers, like how Elsa can create elaborate ice structures while Jack can make it snow and freeze things with a touch. They could also learn from each other. Elsa might teach Jack about controlling her kind of ice, which is more about building and creating, while Jack could show Elsa how to have more fun with ice, like skating on frozen ponds he creates just for that. It could be a really interesting exchange of skills and personalities.
One idea could be that Elsa and Jack Frost discover they both have the power to control elements in a unique way. They could team up to save a magical world that is being threatened by a dark force that can nullify their powers. Another plot could be that they meet and initially clash because of their different approaches to using their powers, but then gradually learn from each other and fall in love.
Jack Frost is very mischievous and free - spirited. Elsa, on the other hand, is more reserved and has a sense of responsibility towards her kingdom. Their personalities could clash in that Jack might do things without thinking about the consequences for Elsa's people, like creating wild ice storms just for fun. However, they could also blend well. Elsa's sense of order could temper Jack's wildness, and Jack's spontaneity could help Elsa break out of her shell a bit more.
Imagine Elsa and Jack Frost cross paths. Elsa is intrigued by Jack's ability to control ice in a different way than she does. But then an evil force emerges that targets both of them. To protect Elsa, Jack sacrifices himself. Elsa is left all alone, mourning for the friend she just found. She blames herself for not being strong enough to save him, and she returns to Arendelle, but with a heavy heart filled with sorrow for the loss of Jack Frost.
Well, it's possible that such a fanfiction exists. Elsa and Jack Frost are from different fictional universes (Elsa from Frozen and Jack Frost from Rise of the Guardians), but in the world of fanfiction, people often cross over characters and create all kinds of scenarios. However, I haven't personally come across a 'pregnant' fanfiction involving them. You might have to search on some dedicated fanfiction websites to find out for sure.
Yes, there are. However, the quality can vary a great deal. Some might focus more on the relationship aspect between Elsa and Jack Frost leading up to the pregnancy, while others might be more about how their respective powers interact during this special time. It's really a matter of personal preference when it comes to finding a good one.
A third common theme is adventure. They are both from magical worlds, and fanfic writers like to take them on adventures, whether it's through different seasons for Jack or different parts of the enchanted forest for Elsa. These adventures not only test their powers but also strengthen their relationship.
I'm not sure if there is an existing 'jack frost x elsa pregnant fanfic' specifically. There are a vast number of fanfics out there in the fandom world, and it might exist, but it's not something that I can confirm with certainty. You could try searching on some major fanfic websites to see if you can find one.
