Spider - Man's relationship with the remaining Avengers would be different. He might be more assertive in his role, not wanting to be seen as just a kid anymore. He could form closer bonds with heroes like Captain America if he's still around, learning from their leadership and experience. At the same time, he may feel a sense of rivalry with some of the other heroes who are also trying to step up in the post - Infinity War world.
His relationship with Aunt May would likely become more strained as she becomes overprotective, fearing she could lose him too. With his friends at school, he might become more distant as he is preoccupied with superhero duties. He could also be more cautious around MJ, not wanting to put her in danger in the new, more dangerous world.
The Infinity Stones would likely put a strain on Spider Man's relationships. His friends and family might be worried about the power he holds. For example, Aunt May might be constantly afraid that he'll get hurt or that the power will change him for the worse. His relationship with MJ could also be affected. She might be in awe of his new power, but also a bit intimidated.
Perhaps Spider - Man starts to train harder in order to be better prepared for future threats. He could seek out new mentors, like Doctor Strange if he's still around. He might also get involved in some sort of community rebuilding effort, using his powers to help the common people who are now in a state of chaos and fear.
With Iron Man, their relationship could grow deeper. Spider - Man could look up to Iron Man even more, and Iron Man could see Spider - Man as a more equal partner. For example, Iron Man might trust Spider - Man with a crucial part of his plan to stop Thanos.
In a reverse Spider - Man story, the relationship with the police could be reversed too. Normally, Spider - Man has an uneasy but mostly positive relationship with the cops. But if Peter is causing trouble, the police would be actively trying to catch him. Also, his relationship with other superheroes in the Marvel universe, if they exist in this story, would be completely different. They would likely view him as a threat and try to stop him rather than collaborate with him as they might in the traditional story.
Yes, Spider-Man was in the Infinity War comics. He played an important role in the battle against the cosmic threats.
It would likely strain his relationship with Iron Man. Since Iron Man supported the Sokovia Accords, Spider - Man, if he's against them, would find himself at odds with his mentor. Their interactions would become more tense and filled with ideological differences.
His relationships could also play a big role in his development. Maybe he forms a really close bond with one of the other Avengers during the war. This friendship could teach him new things, like how to better control his powers or how to be more of a team player. And if he loses this friend in the war, it could be a huge turning point for his character, making him more determined and perhaps a bit more jaded.
His relationship with Mary Jane would likely become more normal. Instead of constantly worrying about his safety while he's out fighting crime, they could focus on building a more traditional family life.
His relationship with Mary Jane would likely be affected. She might sense that something is different about Peter (Spider - Man). He could become more distant or moody because of the symbiote's influence, and this could cause some strain in their relationship.
He might become more serious. Having such a powerful item would weigh on him.
