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.
In this fanfiction scenario, Jack Frost as a human might have to deal with the human perception of him. People might be initially afraid of his icy blue eyes or his strange ability to cool things down. But as he shows his kind nature, they start to accept him. He could also learn about human relationships and how they are different from the relationships he had in his non - human form.
One idea could be that Jack Frost turns into a human to experience the warmth of human emotions. He might find himself in a small town during winter. As a human, he discovers the joy of a hot drink on a cold day, something he never truly understood as a spirit. He could also fall in love with a local girl who is kind - hearted and loves the winter. This newfound love makes him question whether he wants to return to his former state or stay human forever.
Well, at first, Jack Frost as a human might be very confused. He could be disoriented by all the new sensations and the lack of his ice powers. But as time goes on, he might start to appreciate the simple pleasures of being human, like the warmth of a hug or the taste of hot chocolate.
A good one often has well - developed characters. For Jack Frost, his transition from his normal form to human (if that's the plot) should be believable. The writer should capture his essence, like his mischievousness and his connection to winter. Also, the story should have a solid plot. Maybe it's about Jack Frost experiencing human emotions for the first time and how he copes with them. Good grammar and spelling are also important as they make the reading experience smooth.
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.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). There are often a lot of filters you can use to narrow down the search specifically for Jack Frost human fanfiction in the 'Rise of the Guardians' fandom. Another option is FanFiction.net, which has a large collection as well. Some Tumblr blogs also curate and share great fanfiction, so searching relevant tags there might be fruitful.
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.
A more adventurous plot could be that Jack Frost, now human, discovers he has a special mission. Maybe there's a new threat to the winter world that only he, with his unique knowledge as a former winter spirit, can stop. But he has to rely on his new human skills and the help of his human friends to succeed.
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.
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.'
Yes, there are likely fanfictions out there with such a premise. Fanfiction writers often come up with creative and unexpected relationships between different fictional characters. They might explore how Danny Phantom's powers and his character would be affected by being Jack Frost's son, and could create really interesting storylines that combine the elements from both universes.
