Have them share personal stories during the quieter moments in the game. Alex could talk about his previous experiences in Jumanji, and the OC could share about their life outside the game (if relevant). This sharing of stories would create a bond between them. Also, they could have small moments of kindness towards each other, like the OC patching up Alex's wounds after a battle, which gradually deepens their relationship.
You can start with them having a bit of a rocky start. Maybe Alex is too brash for the OC's liking at first. But as they face challenges together in Jumanji, they start to see the good in each other. For example, Alex's courage impresses the OC during a fight with a game - created monster, and the OC's intelligence helps them solve a difficult puzzle, earning Alex's respect.
Another plot could involve the OC being from a different time or dimension within Jumanji. Alex has to figure out how to get the OC back to their own place while also dealing with the normal chaos of the game. Along the way, they develop a deep friendship that changes both of them and how they view the game world.
Start with small interactions. For example, have them meet in the school library while looking for books on magic. This initial encounter can be the foundation for their relationship.
Another theme is friendship and loyalty. The OC usually forms a strong bond with Alex. They stand by each other through tough times, like when facing off against villains or dealing with personal issues. It shows how their relationship evolves over time and becomes something really special.
Another theme is self - discovery. The presence of the OC in Alex Nunez's life can trigger a journey of self - discovery for both characters. The fanfictions may show how they learn more about themselves, their strengths, and their weaknesses as they interact with each other. This can be seen in stories where they face challenges together and have to grow as individuals to overcome them.
Alex and Marissa's popularity as a pairing in fanfiction also lies in the fact that their relationship in the show was full of potential that wasn't fully explored. Writers see this as an opportunity to develop their relationship further. They can create scenarios where Alex helps Marissa break out of her shell more, or Marissa helps Alex become more in touch with her softer side. There are so many untapped stories waiting to be told about them.
Often, the OC will have a troubled past that Alex helps them overcome. This could involve the OC being on the run from something or having lost someone dear to them. In some fanfictions, the OC is from another planet or dimension and Alex has to help them adjust to life on Earth. This creates a lot of opportunities for character growth and relationship building between them.
A common theme is friendship. Often, the OC will form a unique bond with Alex Ernst, perhaps going through various challenges together. Another theme is self - discovery. The OC may be on a journey of finding out more about themselves while interacting with Alex Ernst.
The relationship could also develop in a more platonic way. They could be like sisters, supporting each other during doctor's appointments and prenatal classes. They might have arguments along the way, but always come back to support each other because they know how tough pregnancy can be.
Seth could be a great addition. His quirky personality could add some humor and unexpected twists to the story. For example, he might accidentally get involved in Marissa and Alex's plans and create chaos in a funny way.
First, you need to understand the character of Alex Mercer well. Know his backstory, his powers, and his motives. This will help you create a more believable interaction with your OC. For the OC, give them a distinct personality and backstory too. They should not be a flat character. Second, start with an interesting hook. It could be a situation where the OC and Mercer first meet in a dangerous or unexpected way. Third, develop their relationship gradually. Don't rush into a deep connection right away. Let it build over time as they face challenges together.
