Neither might be fully dominant. They could end up being equal partners. Sherlock's deductive reasoning and the Doctor's knowledge of the cosmos could complement each other so well that they work side by side. They would respect each other's abilities and share the decision - making process. For instance, in a case where an alien is using human technology to cause chaos, Sherlock would analyze the human part of the situation while the Doctor figures out the alien technology involved, and they would jointly come up with a solution without one being clearly in charge over the other.
It could be Sherlock. His deductive reasoning skills are so sharp that he can often lead the way in an investigation. He has a very strong will and is not easily swayed by others, even someone as charismatic as Tony Stark.
The Twelfth Doctor might seem more dominant at first because of his no - nonsense attitude. However, the Thirteenth Doctor's charm and adaptability could quickly make her a force to be reckoned with. In different situations, either could take the lead. For instance, if it's a scientific problem, the Twelfth Doctor's in - depth knowledge might make him dominant. But if it's about making friends with an alien species, the Thirteenth Doctor's social skills could put her in the dominant position.
It could be the 10th Doctor. He has so much experience and knowledge about the universe, time, and different species. His confidence and ability to take charge in difficult situations would likely make him dominant.
In this fanfic, neither might be more dominant. They could be equal partners. Harry Potter's immortality gives him the ability to endure many challenges, and his magic is a great asset. However, the Doctor has his own set of skills like being able to quickly analyze complex situations and having access to a wide range of alien technology. They would probably complement each other rather than one being dominant over the other. For example, when facing a threat that is both magical and technological, they would need to work together, with Harry using his magic to deal with the magical aspects and the Doctor using his technology to handle the technological parts.
The Joker would probably be more dominant in terms of manipulation. He's a master of psychological warfare and could easily manipulate Pennywise into doing his bidding. For example, he could play on Pennywise's need for fear and chaos, and direct it towards his own goals in Gotham.
Neither might be more dominant. In a 'naruto meets miku fanfiction', they could be equals. Naruto has his physical strength and combat abilities, but Miku has the power of her music. They could complement each other. For instance, Naruto could protect Miku while she uses her music to boost their morale or even to influence the minds of their enemies. So rather than one being dominant, they would work together in harmony.
It depends on the writer's perspective. If the writer wants to focus on Inuyasha's brute strength and his experience in battles, then Inuyasha would be more dominant. He's used to taking charge in dangerous situations.
It could be a powerful sorcerer who has turned to the dark side. This sorcerer might be using his magic to manipulate events in Sherlock's world for his own gain. He could be creating illusions and false trails to throw Sherlock off, while also using his magic to fight against Doctor Strange.
Well, in fanfiction, when Sherlock meets the Doctor, they might end up solving some extraordinary mystery together. Maybe they use Sherlock's deductive skills along with the Doctor's knowledge of the universe. For example, they could be in Victorian London and a strange alien entity shows up. Sherlock would notice the little details about the entity's behavior and appearance, while the Doctor would know what kind of alien it is and how to deal with it.
I think it would vary depending on the writer's perspective. If the writer wants to emphasize the importance of experience and training, then Nightwing might be more dominant. He has years of experience fighting crime in Gotham. On the other hand, if the focus is on raw power and the ability to adapt quickly, Spiderman could be the more dominant character. His powers give him a wide range of abilities that he can use in different situations.
