Spiderman's agility and web - slinging abilities could be combined with She - Hulk's super strength. For example, Spiderman could use his webs to create a net and She - Hulk could throw it with her great strength at enemies. Or Spiderman could swing She - Hulk around to gain more momentum for her attacks.
Hulk would probably win. Hulk's strength is virtually limitless and his ability to get stronger as he gets angrier means that Zangief's grappling skills might not be enough. Zangief is very strong and his wrestling moves are formidable, but Hulk has taken on much stronger opponents in the Marvel universe and come out on top.
The Green Goblin could be a great main antagonist. He is a classic Spiderman villain, and his chaotic nature would clash well with the combined forces of Spiderman and Red She - Hulk. His glider and pumpkin bombs could pose a serious threat to the city and force our heroes to work together in new and interesting ways.
It's really hard to say. Batman is extremely intelligent and has a lot of combat experience. But Spider - Man has superpowers. If Batman had enough time to prepare, he might be able to use his gadgets to counter Spider - Man's powers. However, Spider - Man's speed and strength could give him an edge in a sudden encounter.
One common theme is the contrast between their powers. Hulk has raw strength and Spiderman has agility and webs. Fanfictions often play on how they can complement each other in battles.
One possible plot could be that they have to deal with the media frenzy. Spiderman's identity might be at risk of being fully exposed because of his new high - profile relationship with She - Hulk. They could also team up to fight villains who target them specifically because of their union, like a villain who wants to use their combined powers for evil.
A powerful alien race could also serve as the antagonist. They might see the combined power of Tony and Hulk as a threat to their plans of conquering Earth. So they try to separate them and take them out one by one. This would force Tony and Hulk to work together even more closely to defeat this common enemy.
One great Hulk x Spiderman fanfiction is 'The Unlikely Alliance'. It shows how the two superheroes, with their very different powers and personalities, team up to fight a common enemy. Their interactions are really interesting as Hulk's brute strength combines with Spiderman's agility and intelligence.
One possible storyline could be that Spiderman and Red She - Hulk team up to fight a common enemy. Maybe a powerful villain has emerged in the city and their combined skills are needed to take it down. For example, a super - intelligent villain who has created a device that can disrupt all communication and power systems in the city. Spiderman's agility and web - slinging abilities along with Red She - Hulk's strength and durability would make for an exciting battle.
