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 Guardians would be in a state of panic. Bunny would be angry and ready to hop into action right away. He'd probably be the first one to want to charge in and rescue Jack. Tooth would be worried about Jack's well - being, not just physically but also emotionally. She might be concerned that Pitch could damage Jack's spirit. And Sandy, he'd communicate through his dreams. He could try to reach Jack in his sleep, giving him strength and hope.
Deku might be completely shocked at first. Since Bakugou has always been so aggressive towards him, he would never expect such a confession. He might just stand there, mouth agape, not knowing what to say.
Jack Frost is often depicted as a magical winter spirit who brings cold and frost. He's known for his mischievous nature and the ability to create winter wonderlands.
He might cry a lot. Deku is very emotional, and being cheated on would be a very painful experience for him. He could also get angry, which is rare for him, but this situation would be so unjust that he might not be able to hold it in. He'd probably start to question his self - worth too, thinking that there was something wrong with him that made his partner cheat.
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.
The original story of Jack Frost is often associated with the personification of frost, ice, snow, and cold winter weather. He is depicted as a sprite or spirit. In some tales, he is seen as a mischievous character who decorates windows with ice patterns during the winter nights.
