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.
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.
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.
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.
In a 'jack frost goes back in time fanfiction', he could go back to a time of great winter festivals in a long - forgotten civilization. There, he gets caught up in the local politics and superstitions. The people might think he's a sign of good or bad luck. He has to navigate through their beliefs and also deal with a mysterious force that is causing the winter to be harsher than it should be. Maybe he'll make new friends and learn some old winter magic that he can bring back to his own time.
Thor might be a great ally for Jack Frost. Thor is used to dealing with magic and powerful beings from different realms. He would be less likely to be intimidated by Jack Frost's powers. They could both use their elemental - related powers (Thor with lightning and Jack Frost with ice) to create powerful combined attacks against their enemies. For example, Thor could strike his lightning into Jack Frost's ice structures, creating a powerful blast of energy.
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.
Well, in this kind of fanfiction, the relationship between Jack Frost and the original character (OC) can be really diverse. It could be a friendship where they start off as strangers and gradually become close pals, perhaps sharing their unique powers and experiences. For example, the OC might have a special power related to nature, and they team up with Jack Frost to protect the world from some dark force.
It could be an ancient ice - hating wizard. This wizard might have been banished long ago but now that Jack Frost has gone back in time, he sees it as an opportunity to stop winter from ever existing. He could use his dark magic to melt all the ice and snow in the past, which would have a ripple effect on the future.
One popular theme is Jack Frost's origin story. Many fanfictions explore how he became the Jack Frost we know, his past life before being a magical being. Another theme is his relationships, like his friendship or possible romantic relationships with other characters from Once upon a time.
