Older family members, like grandparents, might have some knowledge about time travel in the family's past. They could either be very helpful, guiding Jack through his experiences, or they could be hesitant because they know of the potential risks. Maybe they had a bad experience with time travel in their youth and don't want Jack to go through the same.
His parents could be in his family. Maybe his father is an ancient frost giant with great power over ice and snow, and his mother could be a gentle spirit who gives life to the frozen landscapes. There might also be siblings, like a sister who can create beautiful ice flowers.
Perhaps Jack Frost time travels to a parallel universe where his family has a completely different life. His family could be powerful rulers in this universe, and he has to learn to fit in while also trying to figure out how to get back to his own world. Along the way, he forms new relationships with his alternate - family members and discovers new aspects of his own identity.
One great Jack Frost time travel fanfiction is 'Frost's Journey Through Time'. In it, Jack Frost travels back to key moments in winter history and his own past. It's really interesting as it shows how his actions in the past could change the present. Another one to check out is 'Time - Twisted Jack'. This one has a more complex plot where Jack's time travel is a result of a magical accident and he has to find his way back while dealing with the consequences of his presence in different eras.
The plot could involve Jack Frost initially being shocked to find his family. He may have thought he was the only one of his kind. His family might have been looking for him all this time. They could introduce him to the family traditions and ways of using their frost powers. And together they might go on an adventure to save their winter realm from some sort of threat.
The concept of Jack Frost time travel is appealing because it allows for so much creativity. It combines the magic of Jack Frost, who is already a very interesting character, with the mystery and adventure of time travel. We can see different versions of winter and how Jack might have influenced it throughout history or in different timelines.
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.
At first, their relationship might be a bit rocky. Loki is used to his own schemes and Jack Frost has his own way of doing things in the winter realm. But as they interact more, they start to see the good in each other. Loki realizes that Jack Frost's cold exterior hides a kind heart, and Jack Frost sees that Loki's mischief is often a cover for his insecurities. They start to share their powers and knowledge. For example, Loki teaches Jack Frost some Asgardian magic, and Jack Frost shows Loki how to control ice in new and interesting ways. This sharing and mutual growth strengthen their relationship over time. They also start to defend each other against any threats or negative opinions from others, which further cements their bond.
The traditional Jack Frost is often depicted as a male figure with a more masculine build. In a fanfic where Jack Frost is a girl, she could have a more slender and graceful physique. Her hair could be long and flowing, perhaps in icy blue or white tones, compared to the shorter hair often given to the male version. Also, her clothing could be more flowing and feminine, like a long, icy - blue dress instead of the more rugged male attire.
He could transform into a human and use his powers in unique ways. For example, he might be able to create ice sculptures with his bare hands more intricately than before. Since he's now in human form, his connection to winter is still there but expressed differently.
Often, they might describe his physical injuries in vivid detail. For example, if he has a cut, they could say something like 'A thin line of icy blue blood seeped from the gash on Jack Frost's arm, the coldness of it making the surrounding air even frostier.'
