Wonder Woman would be an interesting character for the Hulk to interact with. She is a powerful warrior with a strong sense of justice. She has her lasso of truth which could potentially be used on the Hulk. It would be interesting to see if the lasso could have any effect on the Hulk in his enraged state. Also, both of them have a certain level of invulnerability. Their fight or alliance could be a great part of a fanfiction, as they could either battle it out or team up against a common enemy.
Superman would be really interesting. Their powers are quite different. Superman is an alien with a wide range of powers like flight, super - strength, heat vision etc. The Hulk, on the other hand, is a being of pure rage with ever - increasing strength. Their encounter could be a clash of ideologies as well. Superman stands for truth, justice and the American way, while the Hulk is often just a force of destruction when enraged. It would be fascinating to see how Superman tries to calm the Hulk down or how the Hulk reacts to Superman's attempts at peacekeeping.
Superman would be really interesting. Ichigo, coming from a world of spiritual powers, would be in awe of Superman's physical strength. And Superman would be curious about Ichigo's ability to see and interact with souls. Their different power sets and moral compasses could lead to some great character - building moments. For example, Ichigo might learn about the importance of using power responsibly in a more global sense from Superman.
Definitely The Flash. Their powers are quite different. The Flash's super - speed could be an amazing contrast to Deku's more physical - based quirk. Deku could learn about time - related concepts from The Flash, and they could have an interesting dynamic when it comes to chasing villains.
Batman would be really interesting. Korra, being used to a world with clear good and bad, could be intrigued by Batman's morally gray methods. Their interaction could involve Korra trying to understand why he doesn't use more lethal force against his enemies, and Batman being fascinated by her bending abilities and how she uses them for both combat and peaceful purposes.
I think Thor and Wonder Woman would make an amazing pair. They both come from god - like lineages. Thor with his Asgardian powers and Wonder Woman with her Amazonian and divine powers could have some epic battles together against common foes. Their different yet powerful fighting styles would complement each other well.
Gohan and Robin would be an interesting pairing. Gohan, with his intelligence and powerful fighting skills, could bond with Robin over their shared smarts and desire to protect their respective worlds. They could exchange knowledge about combat strategies and detective work.
Maeve and Wonder Woman could be an interesting pair. They are both strong female characters, but from very different backgrounds. Wonder Woman could show Maeve a more noble way of using her power, while Maeve could expose Wonder Woman to the harsher realities of the world she lives in.
The combination of Hulk and Superman would be really interesting. You have two extremely powerful beings. Superman's moral compass and the Hulk's uncontrollable rage would create a great dynamic. They could have a friendly sparring match where Superman has to figure out how to hold back the Hulk without hurting him. Or they could team up against a powerful foe, with Superman using his flight and heat vision while the Hulk does his smash attacks.
Definitely Naruto and Batman. Batman would be fascinated by Naruto's powers and his different way of fighting. Naruto, on the other hand, could learn a lot from Batman's strategic thinking. Another interesting pairing could be Naruto and Wonder Woman. They both have strong beliefs and a sense of justice. Their combined strength would be amazing in a fight.
Iron Man. Ryuko is used to dealing with high - tech stuff like her Kamui, and Iron Man is all about advanced technology. Their personalities are also quite different. Tony Stark is more of a witty, sarcastic playboy billionaire, while Ryuko is a determined and somewhat hot - headed fighter. The clash of their personalities and the exchange of their technological knowledge would make for some really interesting interactions.
It's hard to say for sure, but many would argue that it could be Superman. His powers are almost limitless - super strength, flight, heat vision, etc. In a crossover, he would be a force to be reckoned with against most Marvel characters. However, characters like Thor with his godly powers and the ability to control lightning could also give Superman a run for his money.
