There are often fan fictions that focus on their adventures together outside of the main plot of the show. Maybe they go on a quest to find a rare artifact that has a connection to their families' pasts. Some stories might also delve into how their friendship affects the other characters around them, like how it impacts Nick's perception of the world of Wesen.
There might be a Grimm Monroe OC fanfiction where the OC is from a different realm and has to adapt to the Grimm universe. This could lead to interesting cultural clashes and new relationships forming. The story could explore how the OC's different values and beliefs shape their actions in this new world.
First, you should really get to know the characters well. Watch the show multiple times to understand their personalities, quirks, and how they interact with each other. For example, Monroe is a complex character with his love for music and his knowledge of Wesen culture. Grimm, on the other hand, is more about justice and discovery.
Snow - White can be considered a 'dark Grimm story' too. The jealous queen wants Snow - White dead just because of her beauty. She tries several times to kill Snow - White, first with a laced bodice, then with a poisoned comb, and finally with a poisoned apple. It has elements of envy, attempted murder, and the idea of being in mortal danger, which are all quite dark.
Some of the 'Scary Grimm Stories' that stand out are 'The Frog Prince'. Although it has a happy ending, the initial idea of a girl having to befriend a frog can be a bit spooky for some. 'Sleeping Beauty' also has a scary side. The curse that makes everyone in the castle fall asleep and the thorny bushes growing around it give it an eerie feeling. And 'Cinderella' has the mean stepsisters, which adds a touch of horror in the form of their cruel treatment of Cinderella.
Friendship is a very common theme. Most fan fictions explore the deep bond between Miles and Monroe, showing how they support each other through various challenges.
There might be a 'gamer grimm fanfiction' where Grimm discovers a new, hidden level in the game. This level has unique enemies and treasures. He has to use his wits and gaming strategies to navigate through it. For example, he might have to solve complex puzzles and defeat powerful bosses to progress.
One popular Grimm Supernatural fanfiction is 'The Crossroads of Worlds'. It combines the unique elements of both shows in an exciting way, with the characters from Grimm interacting with those from Supernatural.

In Brothers Grimm Bedtime Stories, 'Little Red Riding Hood' is a very famous one. It features a little girl on her way to her grandmother's house and meeting a wolf. 'The Bremen Town Musicians' is another great story. Four animals team up to become musicians in Bremen. Also, 'The Golden Goose' is popular. It has a boy with a special goose that causes some interesting situations.
One of the popular fan fiction stories is those related to 'Supernatural'. Fans create stories that expand on the Winchester brothers' adventures, maybe adding new supernatural creatures or exploring different time periods in their lives. Fan fiction for 'Doctor Who' is also common, with stories about the Doctor's past or new encounters with alien species.
One of the well - liked fan fiction stories are those from the 'Lord of the Rings' universe.
