One idea could be a fanfic that focuses on Elsa's further exploration of her powers. Maybe she discovers a new aspect of her magic in a far - off land. Another could be a story about Anna and Kristoff's adventures during their honeymoon. They could encounter new magical creatures. And a third idea is a fanfic that delves into the backstory of the Northuldra people, showing more of their culture and history before the events of Frozen 2.
Some interesting Frozen 2 fanfic ideas might involve creating alternate endings. For instance, what if Elsa had decided to stay in the Enchanted Forest instead of going back to Arendelle? Or perhaps a fanfic that centers around Olaf's dreams and how they might lead to new adventures. Also, a story about how the spirits interact with the people of Arendelle on a day - to - day basis could be really cool.
Another idea is a fanfic that focuses on the turtles' relationships in a frozen setting. Maybe they get separated and have to find each other again while dealing with the challenges of the cold environment. For example, one turtle could be trapped in an ice cave and the others have to figure out how to rescue him. This would test their loyalty and problem - solving skills.
One idea could be that the dragons in HTTYD are attracted to the cold of Frozen's world and they fly there. The people of Arendelle are initially scared but then they learn about the dragons from the dragon riders. Another idea is that Elsa's ice powers somehow have an effect on the dragons, like making their fire breath turn into ice breath for a short time.
One plot idea could be that Elsa from Frozen somehow ends up in the Fallout wasteland. Her ice powers could be both a hindrance and a help. For example, she could use her ice to create shelters in the harsh environment, but her powers might also attract unwanted attention from raiders or mutants. Another idea is that the Brotherhood of Steel discovers Elsa and tries to study her powers, thinking it could be some sort of advanced technology. A third plot could involve Anna coming to the Fallout world to find Elsa and they team up with some of the more friendly factions in the game to survive and try to find a way back home.
Some interesting Frozen 2 fanfiction plot ideas could revolve around the idea of a magical item. For example, there could be a magical crystal hidden deep in the forest that has the power to either save or destroy both the forest and Arendelle. Elsa and her friends embark on a quest to find this crystal before it falls into the wrong hands. Another idea is that a dark force from outside the known world tries to invade the forest and Arendelle, and the characters have to unite not only the people of Arendelle and the forest but also other magical beings to fight against it. Also, a plot could be centered around a prophecy that was never fully revealed in the movie, and Elsa and Anna must figure out what it means for their future.
A possible plot could be that there is a lemon - themed festival in Arendelle. Hans, who has returned after his banishment, tries to win Elsa's forgiveness during this festival. Elsa is initially skeptical but as they both participate in the lemon - inspired games and activities, they start to develop a new relationship that is different from their previous encounter.
One plot idea could be that Anna discovers a new magical power within herself and Elsa helps her learn to control it. This could involve a journey through the Enchanted Forest where they face various challenges together and their bond grows stronger as a result. Another idea is a time - travel plot where they go back in time to prevent a past event that had a negative impact on their relationship. They could also face a new villain who is specifically targeting their sisterly bond, forcing them to work together to defeat the foe.
Another plot idea could be a what - if scenario. For example, what if one of the sisters had a different power? This could change the whole dynamic between them and the story. Say, if Elsa had the power to control time instead of ice. It would lead to different challenges and interactions with Anna, like having to deal with the consequences of changing time to save someone, but also the potential chaos it could cause in Arendelle.
One idea could be that Spider - Man gets transported to the world of Frozen. He could use his web - slinging abilities to traverse the icy landscapes. Maybe he helps Elsa control her powers better by showing her how to focus her energy, like he does when he's swinging through New York.
A really cool idea could be a Pokémon fanfiction set in a post - apocalyptic world that has been frozen over. A lone trainer travels across the icy landscape, trying to find and rescue rare Pokémon that are on the verge of extinction due to the extreme cold.
One idea could be a fanfiction where Elsa discovers a new, hidden power within her that allows her to communicate with animals. This could lead to all sorts of adventures as she teams up with a talking fox to save the kingdom from an unknown threat.
