They could start with a simple mutual admiration for each other's powers. Then, as they are thrown into more and more adventures together, they begin to trust each other more. For example, in a battle against a powerful enemy, Spider - Man saves Ms. Marvel from a dangerous attack, and she in turn helps him out when he's in a tight spot. This back - and - forth of saving and being saved can deepen their relationship.
There are also fanfictions where their relationship develops more slowly. It might start with small acts of kindness, like Spiderman helping Ms Marvel when she's having a tough day as Kamala Khan, her civilian self. These small moments build up over time, and they gradually realize that they care for each other more than just as comrades. It's a very natural and sweet progression that many fans enjoy reading about.
To develop their relationship in fanfiction, one approach could be to give The Vulture a more sympathetic backstory. Maybe he was wronged by the city's elite and turned to crime as a way to get revenge. Spiderman, upon learning this, starts to see him in a different light. They could then have a series of interactions where Spiderman tries to persuade The Vulture to use his skills for good. Also, if there was an event that put someone they both care about in danger, like a civilian or a family member, they would have to cooperate to save that person, which would deepen their connection.
They could start as reluctant allies. Spiderman is a bit put off by Gwenpool's wild ways at first, but as they face more challenges together, he begins to see her heart and they gradually become friends. Then, as they save each other's lives a few times, a deeper bond forms.
Put them in a life - or - death situation. Maybe they are trapped in a collapsing building during a villain attack. They have to rely on each other to survive. Eraserhead could use his combat skills and quirk to fend off immediate threats, while Ms. Joke uses her wits and quirk to find a way out. This extreme situation would strengthen their relationship and make them realize their feelings for each other.
In a fanfiction, their relationship could develop through a series of encounters. For example, Spider - Man could accidentally damage some of Poison Ivy's precious plants while swinging around the city. This angers her, and she targets him. But as they clash, they also start to learn about each other. Spider - Man realizes that Poison Ivy has a valid point about protecting nature, and Poison Ivy sees that Spider - Man is not just a pest but a hero with good intentions. Over time, this could lead to a more complex relationship that includes elements of friendship or even a strange kind of attraction.
They could start by having more in - depth conversations. For example, sharing their fears and insecurities about being superheroes. This would deepen their emotional connection.
By showing more of their daily interactions. For example, Peter coming home late as Spiderman and Aunt May being worried but also starting to suspect something. These small moments can build up their relationship.
It can start with mutual respect. Spiderman admires Black Widow's experience and skills, and she respects his unique abilities. They could have conversations during missions where they share their thoughts on heroism and sacrifice. This would gradually build a connection between them.
One idea could be a time - travel fanfic. Spiderman and Ms Marvel accidentally get sent back in time and have to find a way to get back to their own time while also not disrupting the past too much. They could meet younger versions of other superheroes and have some really interesting interactions.
Deadpool could use his sense of humor to break through Spiderman's dark thoughts. He might crack jokes that at first annoy Spiderman but eventually start to make him see things differently. As time goes on, Spiderman could come to appreciate Deadpool's unique way of looking at life, and they could become really close friends. They could also have deep conversations in between their crazy adventures. For example, while sitting on a rooftop after a fight, Deadpool might share some of his own experiences with pain and how he copes, which makes Spiderman feel less alone.
