They could interact in a way where Doctor Strange needs Sherlock's help to solve a mystery within the magical community. There might be a political intrigue or a theft of a powerful magical item, and Strange realizes that Sherlock's deductive reasoning is what's missing. Sherlock, being pulled into this new world, starts to learn about magic while also applying his normal detective skills. He might question Strange's motives and actions, leading to some interesting debates between the two as they work together.
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.
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.
Well, Jack Harkness from Torchwood would probably be quite intrigued by Sherlock's deductive abilities. He might initially test Sherlock, throwing out strange cases to see how he solves them. Sherlock, on the other hand, would likely be a bit put off by Jack's flamboyant nature at first but would soon realize his value in dealing with the more otherworldly aspects of cases.
The Hulk could be a bit of a mystery to Sherlock. He would be intrigued by the dual nature of Bruce Banner and the Hulk. Sherlock might try to find a way to control the Hulk's transformations through his scientific knowledge and understanding of human psychology. Meanwhile, the Avengers would be both amused and impressed by Sherlock's unique methods.
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.
Well, Doctor Strange's magic is more about manipulating energy and dimensions. His spells are based on gestures and incantations from the Marvel universe. Harry Potter's magic is more about using wands and specific spells like 'Expelliarmus' or 'Lumos'. If they were to interact, Doctor Strange might be able to enhance the power of Harry's spells by adding his own energy manipulation. For example, if Harry were to cast a shield charm, Doctor Strange could use his magic to make it stronger and cover a larger area.
Well, Hermione could be really intrigued by Doctor Strange's library. She might ask him all sorts of questions about the books and scrolls he has, and they could exchange knowledge about different magical concepts. For example, Hermione could learn about the use of astral projection from Strange, and in return, she could teach him some of the more complex spells from the wizarding world.
The characters would have some really interesting interactions. For example, Hermione might be both fascinated and a bit frustrated by Harry's new powers. She would try to study them while also scolding him if he uses them recklessly. Ron, on the other hand, would probably be in awe and a bit jealous at times. And the professors at Hogwarts would be very cautious about Harry's powers, especially Snape who would be suspicious as always.
In fanfiction, they often interact as two brilliant minds. For example, Stark might be in awe of Strange's magical abilities while Strange is intrigued by Stark's technological innovations. They could exchange ideas, with Stark suggesting technological solutions to problems Strange faces with magic, and vice versa.
For Sherlock, his character can be developed by showing his reaction to Merlin's magic. At first, he might be skeptical and try to find a scientific explanation. But as he witnesses more of Merlin's powers, he has to re - evaluate his world view. This could lead to a more open - minded Sherlock. For Merlin, being in a modern world with Sherlock could make him more aware of the need for secrecy regarding his magic. He might also learn to use his magic in more creative ways to solve modern - day problems.
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.
