The main characters would be Jack, who is the center of the memory exploration. The guardians, which could include characters like North, Tooth, Bunny, and Sandy, would be the other main characters. They are likely to have different reactions to Jack's memories. For instance, North might be more focused on the positive and heartwarming memories, while Bunny could be more skeptical and look for any hidden motives or meanings in Jack's past. Tooth might be interested in the memories related to Jack's relationships, and Sandy could use his dream - like powers to make sense of the more abstract or emotional memories.
Perhaps the guardians are Jack's friends or allies who have developed a special ability to peek into his memories. They could be people with psychic powers or some kind of technological device that enables them to view his memories. Their relationship with Jack might be one of trust and loyalty, and by watching his memories, they are trying to help him in some way, like solving a problem he's facing or unlocking his hidden potential.
Well, it could be that the guardians are learning about Jack's past through his memories. Maybe they discover things about his childhood, his fears, or his hopes. It might also show how his memories shape his present actions and relationships with the guardians.
Perhaps in this fanfiction, the guardians are watching Jack's memories to find a way to help him overcome some sort of trauma or problem. As they go through his memories, they might come across key events or people that are relevant to his current situation. For example, they could find out about a long - lost friend or a tragic event that has been affecting Jack's behavior. This exploration of his memories could lead to a journey of self - discovery for Jack and a deeper connection between him and the guardians.
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).
Sakura might also be a main character. In the original series, she is part of Naruto and Sasuke's group. Her skills as a medical ninja could be crucial in a story that involves future memories. Maybe Naruto's future memories show a situation where Sakura's medical skills are the key to saving someone important. Additionally, Kakashi could be in it too. His experience and wisdom could help Naruto make sense of his future memories and figure out what actions to take.
Obviously Naruto himself is the central character since the story is about him losing his memories. Sakura would likely be involved too. She's one of Naruto's closest friends and a medic - ninja, so she might try to find a way to restore his memories.
Clary is the central figure. Valentine might also be involved in some fanfictions, either as an obstacle trying to prevent Clary from getting her memories back because he doesn't want her to discover certain secrets, or in a more complex way where his past actions are somehow related to the loss of her memories in the first place. And of course, the Lightwood family members are likely to be involved, given their importance in Clary's life and the Shadowhunter community.
Naruto and Star - Lord would be likely to interact. Naruto's friendly and outgoing nature would draw him to Star - Lord's charisma. They both have a sense of adventure and a desire to protect their own groups. Naruto might be curious about Star - Lord's blasters and spaceship, while Star - Lord could be interested in Naruto's ninjutsu.
There's no way to tell for sure without reading the fanfiction. However, it's possible that the main characters could be people who are somehow connected to the watches, perhaps collectors, or people who inherit the watches and are then thrust into the events related to the memories within them.
Pitch Black would be a likely main antagonist. He could manipulate Jack Frost into turning dark, as he has a history of preying on the insecurities of the Guardians.
