One possible plot could be that Superman is somehow transported to the Marvel universe where the Avengers operate. He initially clashes with them due to misunderstandings. For example, his super strength might be seen as a threat. But then they realize they can team up to fight a common enemy, like a powerful alien or a super - villain who has the ability to manipulate time. They combine Superman's powers such as heat vision and flight with the Avengers' diverse skills like Iron Man's technology and Captain America's leadership to save both universes.
One possible plot could be that Superman is somehow transported to the Marvel universe. He might initially be seen as a threat by the Avengers. But then they realize he's there to help against a common enemy, like a powerful cosmic villain. They would team up, with Superman's super strength and flight abilities complementing the Avengers' various skills.
If Superman met the Avengers in a fanfiction, there would likely be a clash of egos at first. Superman is used to being one of the most powerful beings on his Earth, and the Avengers have their own set of strong personalities like Iron Man and Thor. However, they would soon realize that they could achieve great things together. Maybe they would team up to fight a common enemy from another dimension that neither could handle alone. Superman's super strength and flight could combine well with the Avengers' diverse powers and teamwork skills.
In some fanfiction, Superman's powers might be a bit different when he crosses over with the Avengers. For example, his heat vision could interact in a new way with Iron Man's suit technology. The story could explore how the Avengers, with their unique skills, and Superman work together to stop a powerful villain like Loki who has managed to gain control over some Kryptonian tech. There could be a lot of interesting character interactions, like Captain America trying to understand Superman's sense of justice which is different from his own but still has similarities. Superman, on the other hand, might be intrigued by the Avengers' teamwork and how they function without having powers like his.
Another great pairing would be Superman and Captain America. Superman is an alien with god - like powers, while Captain America is a human with peak physical and moral strength. Cap could teach Superman about the value of human tenacity and leadership on a more down - to - earth level. And Superman could show Cap what true superhuman power looks like. They could work together to inspire the rest of the Avengers and any other heroes they encounter in a battle.
Definitely Superman and Thor. They both have super strength and are associated with powerful, other - worldly elements. Thor has his hammer and lightning powers, while Superman has his super - strength, heat vision, etc. It would be interesting to see them compete in a friendly strength - based challenge or fight side by side against a really strong foe.
One possible plot could be that a powerful villain from another dimension threatens both the DC and Marvel universes. Superman and the Avengers have to put aside their differences and combine their powers. For example, Superman's super strength and flight could be paired with Thor's godly abilities and Captain America's leadership. They could start off not trusting each other, but as the battle progresses, they learn to work together and defeat the villain in an epic showdown.
Definitely Iron Man and Superman. Iron Man with his technological genius would be fascinated by Superman's alien biology and powers. He might try to create some sort of device to enhance or analyze Superman. And Superman would be interested in Tony Stark's inventions.
They might start by comparing powers. Superman's super strength and flight would be quite a topic. Thor would likely want to have a friendly competition with Superman in terms of strength. Then they could move on to sharing their experiences. Captain America could talk about his battles during World War II, and Superman could share his adventures in saving Metropolis. They could also team up to fight a new, powerful villain that neither could defeat alone. For example, a villain with the ability to nullify Superman's powers and hack into the Avengers' technology.
In fanfiction, he could fit in through his values. Superman has a strong sense of justice and morality, which would align well with the Avengers' goals. He could also form friendships with the members, like a bromance with Thor due to their similar god - like statuses.
