It could be Wonder Woman. She has a strong and commanding presence. She is used to leading in battle and has a lot of experience dealing with powerful foes. Naruto, while also strong, might be more laid - back in a relationship and let Wonder Woman take the lead in many situations.
Wonder Woman would likely be more dominant in a Wolverine meets Wonder Woman fanfiction. She has years of combat training as an Amazon warrior. Her powers are not just physical but also magical in nature, like her Lasso of Truth which can force people to tell the truth. She is also a symbol of justice and leadership. Wolverine, while a tough mutant, is more of a lone wolf. He often gets into fights based on instinct. Wonder Woman, on the other hand, can strategize and lead in battle. She can use her powers in more versatile ways compared to Wolverine, who mainly relies on his claws and healing factor.
Well, it depends on the situation. If the fight takes place in the Naruto universe where Naruto can draw on natural chakra more easily and has the home - field advantage, he could be very strong. He also has his Nine - Tails chakra which is extremely powerful. On the other hand, Wonder Woman has years of combat training and her divine weapons. In a battle of wits and strategy, Naruto's experience in fighting various opponents in his world might give him an advantage, but Wonder Woman's overall power set is also very formidable.
Well, one possible plot could be that Naruto, with his ninja skills and strong sense of justice, somehow gets transported to the DC universe. He meets Wonder Woman and they initially clash due to their different ways of handling things. But as they get to know each other, they find common ground in their desire to protect the innocent. Eventually, they fall in love and decide to get married. Their wedding could be a grand affair with ninjas and Amazonians coming together.
Natsu could also be the more dominant one. Despite Acnologia's power, Natsu has an indomitable will. He's not one to be easily pushed around. In a relationship, his enthusiasm and his strong sense of right and wrong could make him take the lead. He would stand up for what he believes is right for both of them, and in that sense, be the more dominant figure.
It could be Naruto. Since he has the will of fire and is quite stubborn himself, he would likely keep pushing until he gets answers.
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.
Lex Luthor could be a main antagonist. He might see their union as a threat to his power and schemes, and try to break them apart or use their relationship against them.
There could also be other supporting characters. For example, Batman might be a character in the fanfiction. He could be a bit skeptical about their marriage at first, worried about how it will affect the balance of power in the superhero world. Another possible character could be Lois Lane. Her reaction to Superman marrying Wonder Woman could add an interesting dynamic, like she might be a bit jealous but also come to accept it in the end.
It could be Naruto. He has a strong will and the ability to make others follow him. His positive attitude might overshadow Indra's more brooding nature.
Kurotsuchi could be the more dominant one. She is from Iwa and has a no - nonsense attitude. She's not easily swayed by others and might not be impressed by Naruto's fame. So she could be the one making decisions and leading the way in their interactions.
