Maybe in the fanfiction, Sulley discovers that Randall has a hidden side. Randall might be secretly trying to protect the monsters from a new threat in the human world that no one else is aware of. Sulley initially doubts Randall but as he sees the evidence, he decides to help Randall. They then team up and use their different skills - Sulley's big and strong nature and Randall's sneaky and intelligent ways - to overcome the threat and in the process, their relationship changes for the better.
It's also because their personalities are so different yet complementary. Sulley is big and strong while Mike is small and smart. Fanfiction writers can play with these characteristics in various ways. For example, they can create stories where Mike's ideas and Sulley's ability to execute them lead to amazing results. This contrast makes for interesting and engaging stories.
One good example could be fanfictions that focus on their adventures outside of work. For instance, a story where they go on a trip to a new, uncharted part of the monster world. Another might be ones that explore their friendship during their childhoods, like how they first met at monster school.
In a different take, Sulley and Randall could be partners in a secret experiment within Monsters Inc. They might be working on a new way to collect energy from kids without scaring them. As they work closely together, they discover that they have a lot in common when it comes to their love for the monster world and their hopes for its future. This shared passion could lead to a deeper bond between them, different from the adversarial relationship in the movie.
Friendship is a very common theme. Since the OC is a new character, often the story focuses on how they become friends with Sulley. For example, they might help each other out in tricky situations at Monster Inc.
Monsters Inc. is set in a world where monsters generate energy from children's screams. But as the story progresses, we discover that laughter can generate even more powerful energy, leading to a major shift in the monsters' way of doing things.
Monsters Inc is not based on a real story. It's an imaginative concept where monsters live in a parallel world. The movie uses this fictional setting to tell a story about friendship, like the relationship between Sulley and Mike. They work in a company that has very unique and out - of - this - world rules.
It's a fun and heartwarming story set in a world where monsters generate energy by scaring kids. But there's a twist - the main characters discover that laughter is more powerful than fear.
There's also a fanfic called 'Sulley and the Mysterious OC'. In this one, a mysterious OC shows up at Monster Inc and Sulley is the first to notice something strange about them. It has a lot of mystery elements and is quite engaging. It delves into the idea of how the monsters at Monster Inc react to an unknown entity in their midst.
