For Percy, his loyalty and sense of adventure can be emphasized. He could be the one to initiate contact with Elsa, seeing her as a new and exciting mystery. His skills in combat and his ability to think on his feet would come in handy when they face challenges together. For Elsa, her growth from a withdrawn and fearful queen to someone more open and trusting can be shown. Meeting Percy, who is so different from the people in her world, could be a catalyst for this change.
Percy can be developed by showing his struggle to understand Elsa's world at first. He's used to the Greek mythology stuff, but Elsa's ice magic and her kingdom are completely new to him. This can make him more empathetic and adaptable. Elsa, on the other hand, can be developed through her interaction with Percy's friends at Camp Half - Blood. She might learn to be more social and less isolated. As she sees Percy's relationships with his friends, she starts to open up more and let people in, which is a big step for her character growth.
Percy's development could involve him using his skills in a new way. For example, his ability to control water could be combined with Elsa's ice in creative ways. This would make him more adaptable. Elsa could develop by seeing Percy's loyalty to his friends and trying to form deeper connections herself. As they interact more, they could influence each other's values. Percy might become more patient like Elsa, and Elsa could become more bold like Percy.
Another concept could be that a powerful ancient evil is affecting both the Percy Jackson universe and Arendelle. Elsa and Percy are the only ones who can sense it at first. They must team up, traveling between their two worlds, to find the source of the evil. Along the way, they learn about each other's powers and cultures, and their combined powers are the key to defeating the evil.
Yes, there are some out there. You can start by looking on fanfiction websites like Archive of Our Own. Just search for 'Percy Jackson and Elsa romance' and you'll find various stories. Some might be really creative, imagining how these two characters from different universes could interact and fall in love.
A fanfiction plot could be that there's a rift in the multiverse which causes Elsa's ice powers to go haywire. Percy, being a demigod with a sense of adventure and a good heart, is sent to find the source of the problem. When he meets Elsa, he realizes that she's not just a powerful ice - queen but also a lonely soul. He tries to help her control her powers and in the process, they fall in love. Their love story could then be intertwined with their efforts to close the rift in the multiverse and restore balance to both of their worlds.
One idea could be that Percy and Elsa meet when some sort of magical rift pulls them into the same world. Percy's water powers and Elsa's ice powers could either clash or combine in interesting ways. For example, they might have to work together to stop a new threat that is causing chaos with water and ice elements in the merged world.
One idea could be that Percy, with his water powers, and Elsa, with her ice powers, team up in a magical realm. They could face a common enemy that threatens both their worlds. And as they work together, they start to understand each other's powers more deeply, leading to a strong bond.
Percy could start to form new relationships within the Faunus community. These relationships could teach him different values and ways of life. Maybe he'd meet a Faunus mentor who would help him understand and control his new Faunus powers, if he has them. This would be a big part of his development, as he'd be learning from a completely different perspective than he's used to at Camp Half - Blood.
To develop Percy, you can focus on his loyalty. In a fanfiction with Hermione, this loyalty could be tested in new ways. For instance, when they are in a situation where they have to choose between their own worlds' interests. Hermione can be developed by highlighting her adaptability. She has to adapt to the new world of demigods, with its own rules and hierarchies. You can also show how their individual character traits affect their relationship. Percy's impulsiveness might sometimes clash with Hermione's careful planning, but they can also find a balance and grow together as characters.
Developing his powers further is also a way. Since he's the son of Nyx, he could learn to manipulate different aspects of darkness like creating illusions using shadows or traveling through the dark realms faster. This would not only make him more powerful but also show his growth as a character as he masters these new abilities.
In developing Percy, consider his identity. He is half - god, half - human. In the fanfic, he could struggle more with this identity and Sally could play a role in helping him accept it. Sally can be developed by highlighting her creativity. She could come up with unique solutions to problems they face. Regarding their relationship, develop it by adding conflict. Maybe Percy wants to do something dangerous and Sally is against it. Resolving this conflict can lead to a deeper understanding between them and thus develop their characters further.
