Some fanfiction might also pair them in a sort of 'frenemy' relationship. They could start off not getting along, perhaps due to a misunderstanding or a clash of their methods. But as the story progresses, they come to respect each other. This type of pairing creates a lot of tension and drama in the story, which can be really engaging for readers.
One of the popular pairings is a platonic friendship between Spider - Man and She - Hulk. Their different personalities and abilities make for an interesting dynamic where they can support and learn from each other. Another pairing could be a romantic one, although it's less common. Some fans might enjoy exploring the idea of a relationship between the two, imagining how their powers and personal lives could blend together in a romantic relationship.
A popular pairing could be Spider - Man and Midoriya. People might like this pairing because they are both the main protagonists in their respective stories and share a lot of similarities in terms of their growth, determination, and their sense of justice.
I'm not sure who the absolute best is, but there are some well - known writers in the fanfiction community. Some writers who have a great understanding of both characters' personalities and powers tend to write really engaging stories. You can often find them by looking at the reviews and ratings on fanfiction websites.
The Kingpin could be a great antagonist. He's always been a thorn in Spider - Man's side, and his criminal empire and resources would pose a major threat to both Spider - Man and She - Hulk. He could hire super - powered mercenaries to fight them.
Venom is quite popular in Spider - Man fanfiction. His complex relationship with Spider - Man can be explored in many ways. He can be a villain, an anti - hero, or even an ally in some really creative fanfictions. Another popular one is Gwen Stacy. Fans love to write about her and Peter's relationship, especially in alternate timelines.
One of the most popular pairings is Mega Man and Roll. It's a classic pairing within the Mega Man universe itself, and in crossovers, it can add an emotional depth to the story. For example, if they are in a dangerous situation in a crossover world, their relationship can be further explored as they protect each other.
Peter Parker and Lex Luthor could be a fascinating duo in a different way. Luthor might initially try to use Spider - Man's powers for his own gain, but Spider - Man outsmarts him. This could lead to a complex relationship where Luthor is constantly trying to manipulate Spider - Man, but Spider - Man is always one step ahead, all while they are in the middle of a bigger conflict involving other heroes and villains from both universes.
Spider - Man and Yang could make an interesting pairing. Yang is strong - willed and has a lot of physical power, while Spider - Man is more about agility and his web - slinging abilities. They could have some great banter during combat and learn from each other's fighting styles.
Another possible pairing is Kaine and Cindy Moon. Given Cindy's role as Silk and her connection to the Spider - Verse, a relationship with Kaine can bring about new plotlines. Their combined abilities and their individual character arcs can be intertwined in creative ways in fanfiction.
Mary Jane is also very popular. Fans love to write about her relationship with Peter, whether it's the ups and downs or how she deals with Peter's double life. In some fanfictions, she might even have a more active role, like helping Spider Man in some way.
One storyline could be Spider - Man and She - Hulk teaming up to stop a powerful villain who is stealing experimental technology from Oscorp. Spider - Man uses his agility and web - slinging skills while She - Hulk uses her super strength. Another could be a story where they get transported to an alternate dimension and have to find their way back home while facing strange new enemies. Maybe they also have to deal with a misunderstanding between them at first, like Spider - Man thinking She - Hulk is too reckless, but then they learn to work together effectively.
