The story could end with Anna being rescued by Elsa and Kristoff. They could overpower Hans and lock him up for his crimes. Anna would then be reunited with her sister and the people of Arendelle, and they would all live happily ever after.
One way it could end is that Hans actually realizes the error of his ways during the kidnapping. He releases Anna and helps her return to Arendelle. In return, Anna pleads for leniency for Hans, and he is exiled instead of facing a harsher punishment. This would show a path of redemption for Hans.
Elsa would be extremely worried and angry. She would probably use her powers without hesitation to find Anna. Kristoff would be very determined to rescue Anna. He loves her and would do anything to get her back. Olaf might not fully understand the situation at first but would still try to help, like using his cheerfulness to keep Anna's spirits up while she's kidnapped.
One plot idea could be that Hans' true motives are revealed to be part of a larger scheme to take over Arendelle by using Anna as a hostage. Another could be that Anna manages to outwit Hans during the kidnapping through her kindness and understanding, making Hans question his own actions. Maybe in the fanfiction, Kristoff and Sven come to the rescue and there's an epic showdown in the mountains.
Well, one possible plot could be that Hans kidnaps Anna with the intention of using her as a bargaining chip against Elsa. He might take her to a remote location. Then, Kristoff could find out and go on a heroic rescue mission with Sven. Along the way, he might face various obstacles set up by Hans' minions.
One plot could be that an ancient curse has been placed on Anna that only Hans can break. But Hans doesn't know how to break it at first. They go on a quest together, searching for the solution. During this journey, they encounter various magical creatures and obstacles. As they spend more time together, Hans realizes how much he has wronged Anna and is determined to make it up to her. By the end of their adventure, not only is the curse broken, but they also have a new - found respect and love for each other.
In a different version of the story, Anna and Hans were forced to work together to save Arendelle from a new threat. A powerful sorcerer had cast a dark spell over the land. Anna knew that despite their past, Hans had certain skills that could be useful. 'Hans, we need to put aside our differences for the sake of Arendelle,' she said. Hans agreed. As they journeyed together, they started to understand each other better. Along the way, they faced many challenges and with each one, their relationship evolved. In the end, they managed to break the spell and in the process, a new kind of bond formed between them.
One possible plot in this fanfiction is that Hans kidnaps Elsa not just for power or revenge, but because he is being controlled by some dark magic. He takes Elsa to a remote location where she has to fight not only Hans but also the source of the dark magic to free herself and save Arendelle. Along the way, Elsa might discover new aspects of her powers that she didn't know before.
Well, one possibility could be that Anna is turned into a vampire in a Frozen - themed fanfiction. Maybe she's bitten during one of her adventures in the Enchanted Forest. This could lead to a whole new set of challenges for her and Elsa. Anna would have to deal with her new vampire nature while still trying to maintain her relationship with her sister and the people of Arendelle.
Anna could be the one to save Elsa. After all, she has proven herself brave and determined in the original story. She would stop at nothing to rescue her sister from Hans's clutches.
Anna's fire powers could change the story by making her a more formidable ally. Instead of just relying on Elsa's ice powers, she could now contribute in a different way. For instance, if there's a battle against a dark force, her fire could be used to counter certain attacks.
The plot could revolve around a magically - induced situation. There could be a spell that makes Elsa and Hans believe they are in love. They share a kiss as a result of this false love. However, as they continue to interact, they start to develop real feelings for each other. This would be a journey of self - discovery for both of them. Elsa would have to deal with the idea of loving someone who was once her enemy, and Hans would have to prove himself worthy of her love. The kiss would be the starting point of this complex relationship.
