The 'Doctor Strange Crossover Fanfiction' that pairs him with the Guardians of the Galaxy is also a lot of fun. Strange finds himself in the middle of their wacky adventures in space. His serious and mysterious nature contrasts with the Guardians' more laid - back and comical personalities. There are some really humorous exchanges between them as they try to work together to stop an intergalactic threat.
There's this fic called 'In the Realm of Doctor Strange'. It takes the reader on a journey through different magical realms with Doctor Strange. The author does a great job of painting a vivid picture of these otherworldly places. And the relationship between Doctor Strange and the reader builds in a very natural way throughout the story.
One idea could be that Doctor Strange somehow gets transported to the RWBY universe. Maybe he's there to help deal with a powerful Grimm that has magic - like abilities that the normal Huntsmen and Huntresses can't handle. He could use his magic to teach the RWBY characters new ways of fighting and also learn a thing or two from them about their unique combat styles.
Some great ones could be those that explore alternate universes where the Avengers interact with Doctor Strange in unexpected ways. For example, there might be a fanfiction where they have to team up to stop a new villain that's causing chaos across multiple dimensions. These types of stories often bring out new character dynamics and exciting plot twists.
Sherlock could be highly skeptical of Doctor Strange's magic at first. He might constantly try to find logical explanations for the magical phenomena. Doctor Strange, in turn, could be amused by Sherlock's attempts and then gradually show him the true power of magic. For example, Strange could use his magic to recreate a crime scene in a different way to help Sherlock see new angles of a case.
One idea could be that Sherlock's deductive skills are needed to solve a mystery in the magical world of Doctor Strange. Maybe a powerful artifact has been stolen and Sherlock's unique way of seeing details helps find it. Another could be that Doctor Strange uses his magic to transport Sherlock to different dimensions to solve a case that spans across realities. For example, a serial killer who can move between dimensions and Sherlock has to use Strange's magic to track him down.
The RWBY characters are used to a world full of Grimm and Huntsmen. When Doctor Strange arrives, his different style of magic and his more 'cosmic' view of things would be a shock. For example, he might use his magic to create portals, which could be used for both transportation and as a weapon. The RWBY team would have to adapt to this new form of combat. Doctor Strange, on the other hand, would have to understand the RWBY characters' reliance on Dust and their team - based combat. He might find their loyalty to each other and their cause quite inspiring and adjust his own actions accordingly.
