The two main characters are Elsa and Jack Frost. Elsa is known for her strong will and her struggle to control her powers. Jack Frost is a bit of a mischievous character but also very kind - hearted. In the fanfiction 'elsa meets jack frost', they are the focus, and the story probably explores how their different natures and powers interact with each other.
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.
The main characters are obviously Jack Frost and the Guardians. The Guardians typically include characters like North (Santa Claus), Tooth (the Tooth Fairy), Bunny (the Easter Bunny), and Sandy (the Sandman).
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.
There could be the Guardians. They might play a role in the story. For instance, they could be initially hesitant about Jack Frost's sister being around, fearing she might disrupt the balance. But as they get to know her, they become friends. North could be there, with his jolly self, giving the sister a little magical gift.
In this fanfiction, Marshmallow could be a significant character. He's a large and somewhat intimidating snow creature created by Elsa. But with the baby on the way, he could become a gentle protector. He could stand guard outside their home to keep any potential threats away. Also, the trolls from the Frozen universe could play a role. They are wise and could offer their knowledge on how to take care of a baby with magical powers. They might even perform a special ceremony for the unborn baby.
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.
Well, perhaps a power - hungry wizard from a neighboring magical realm. He hears about the baby's unique powers that combine Jack Frost's and Elsa's abilities and wants to harness that power for his own evil plans. Or it could be a group of dark fairies who are envious of the baby's special connection to both the winter world and Arendelle. They might try to kidnap the baby and raise it to be on their side, away from Jack and Elsa.
Jack and Elsa are the central figures. Jack, with his mischievous yet kind nature, and Elsa, who has grown from a scared girl into a confident queen. In the fanfiction, they are the ones whose relationship is at the core, as they fall in love and get married.
