Well, in many fan stories, their powers are combined in really creative ways. Let's say there's a situation where they face a villain who can control gravity. Spider - Man can use his webs to anchor himself and She - Hulk, preventing them from being flung around. Meanwhile, She - Hulk can use her strength to pull or push objects towards the villain, disrupting the villain's control. Their powers working together can also be a source of character growth for both of them. Spider - Man might learn to be more confident in his physical abilities when he sees how She - Hulk uses hers without hesitation, and She - Hulk could gain more finesse in combat by observing Spider - Man's acrobatic fighting style.
Often, their powers interact in a way that creates a balance. She - Hulk's superhuman strength can be used to take on the more physically imposing threats, while Spider - Man's spider - sense helps them both avoid danger. In a fanfiction scenario where they are in a maze - like villain lair, Spider - Man's spider - sense can guide them, and when they encounter locked doors or barriers, She - Hulk can smash them open. His ability to quickly move around also allows him to scout ahead and relay information to She - Hulk so she can be better prepared for what's coming.
Well, Spider - Man's web - slinging and acrobatic skills combined with Shadowcat's phasing can create some really cool combat scenarios. For instance, Spider - Man can swing Shadowcat into the air and she can phase through obstacles while in mid - air, catching enemies off - guard.
The Avengers interact in various ways. Sometimes they're protective of She - Hulk, like when she first joins the team. Other times, they might be in awe of her strength. For example, Spider - Man could be really excited to team up with her.
She - Hulk's super strength can be a great asset when it comes to taking on larger and more physically powerful enemies. Spider - Man's agility and ability to move quickly can complement this. For example, he can web up enemies' legs to slow them down, allowing She - Hulk to land a powerful blow more easily.
Well, Spider - Man's agility and ability to stick to walls could be really useful in combat situations where She - Hulk is facing off against a more powerful foe. He could quickly move around the enemy, distracting them while She - Hulk delivers powerful blows. His webs could also be used to temporarily restrain the enemy or set up traps.
In fanfiction, their powers could interact in a way that defies the normal rules of the Marvel universe. Maybe Spider - Man's power to stick to surfaces could be transferred to Female One - Above - All in a way that gives her an advantage in a particular battle. Or perhaps she could use her power to manipulate reality to give Spider - Man a new form of his powers, like the ability to fly temporarily. Their combined powers could also lead to the creation of new, unique abilities that are a blend of their individual powers, such as a web - like energy projection that can hold even the most powerful enemies at bay.
In a more cooperative scenario, Spider Man's web - shooting could be used in combination with Female Carnage's shape - shifting. For example, she could transform into a large structure and Spider Man could use his webs to anchor it or create a web - based mechanism around it. Their powers could also clash in a way that creates interesting visual and story - based effects, like when Spider Man's web gets caught in Female Carnage's symbiotic mass and she uses it against him.
Supergirl's super strength and invulnerability could provide a good defense for Spider - man. When they face really tough opponents, she could take the brunt of the attacks. Meanwhile, Spider - man's agility and ability to climb walls could help them access hard - to - reach places during their adventures. His spider - sense could also give them an early warning of danger that Supergirl might not detect right away with her normal senses.
Scarlet Witch's powers of chaos magic could potentially enhance Spider - Man's reflexes. Her ability to manipulate reality on a small scale might make Spider - Man's movements even more unpredictable to his enemies. For example, she could create a reality where Spider - Man's webs are stronger or his jumps are higher.
I'd recommend starting with the most popular ones on websites like Archive of Our Own. They usually have a good summary that can give you an idea if it's the type of story you'll like.
Spider Man's agility and web - slinging abilities can complement Female Thor's brute strength. For example, Spider Man could use his webs to set up traps or swing Female Thor into the air for a more powerful attack.
