You could create a fanfiction where Mike has to face his fears alone in the woods. This would be different from the game as in the game he is mostly with other characters. It could be a more in - depth look at his character growth when isolated.
First, really understand Mike's character from the game. His traits like his bravery and his charm are important to capture. For example, you can start with a scene that shows off his bravado.
Yes, there are some great ones. You can start by looking on fanfiction.net. There are often well - written stories that explore the relationship between Sam and Mike in the 'Until Dawn' universe. Some fanfics might focus on their friendship evolving during the events of the game, while others could take a more romantic angle.
A lot of 'Sam x Mike Until Dawn fanfic' deal with trust. Given the dangerous situations in the game, Sam and Mike have to trust each other. Fanfics might show how that trust is built, broken and rebuilt. Also, the theme of redemption can be there. If one of them makes a mistake during the game's events, the other might help in their redemption process, which in turn strengthens their relationship.
One common trope is the 'outsider' trope. The male OC is often an outsider to the main group in Until Dawn. He might be a new arrival in the area or have a different background that sets him apart. Another is the 'protector' trope. He feels a strong need to protect the other characters, especially the female ones. For example, he could be a martial arts expert who uses his skills to fend off threats. And then there's the 'mysterious past' trope. His past is only gradually revealed throughout the fanfiction, keeping the readers guessing.
First, develop a unique personality for your male OC. Consider his backstory, like if he has a troubled past or a special family. For example, he could be a survivor of a previous horror incident that makes him more cautious in the Until Dawn scenario. Then, think about his relationships with the existing characters. Will he be a love interest for one of the girls? Or a rival to the male characters? Also, build up the tension in the story. Use the spooky setting of Until Dawn to your advantage, like having him explore a creepy part of the lodge alone. This can create suspense and keep the readers hooked.
One common theme is adventure. Since 'Until Dawn' has an adventurous setting, many fanfictions with Sam and an OC involve them going on some sort of adventure together, facing challenges and growing closer through it.
One common theme is the discovery of new powers. Since it's supernatural, the OC often realizes they have some unique ability that helps them in the Until Dawn situation, like seeing the future or controlling the elements.
There's also 'Supernatural Shadows at the Lodge'. This fanfic focuses on an OC who can communicate with the spirits in the game's setting. The author does an amazing job of integrating the OC into the existing Until Dawn lore, making it a very immersive read.
The freedom to create is a big factor. Fanfic writers can create OCs that fit into the Until Dawn universe in unique ways. For example, an OC could be a relative of one of the main characters, and this connection can lead to all sorts of new plot twists. Also, OCs can have different reactions to the horror elements. Maybe an OC is more fearless or more superstitious than the original cast, which makes for interesting reading.
