In a fanfiction like this, there could be a lot of challenges. Their different backgrounds - Peter Parker's normal life as a student and Carol Danvers' military - turned - superhero past - could create some interesting conflicts. But they could also learn from each other. Spider - Man could teach Captain Marvel about the little joys of a normal life, and she could show him how to be more confident in the big superhero world.
One possibility in such a fanfic could be that they meet during a major inter - galactic crisis. Maybe they start off as allies, gradually realizing they have deep feelings for each other. Their different powers could combine in interesting ways to save the day, and this shared experience could be the start of their romantic journey towards marriage.
Imagine in the fanfiction, Spider - Man discovers a new ability during Endgame that can complement Captain Marvel's power. He shares this with her, and they experiment with combining their powers in new ways. For instance, Spider - Man could create a web - like energy field using his new ability, and Captain Marvel could charge it with her cosmic energy to create a powerful shield or weapon against the enemy.
The plot could involve a new villain who targets both of them because of their relationship. This villain might be someone who wants to disrupt the harmony between Earth and the cosmos. Spider - Man and Captain Marvel have to work together to defeat this enemy while also dealing with the challenges of their new - found married life.
One possible fanfiction could involve Spider - Man and Captain Marvel teaming up during the Endgame battle. Maybe Spider - Man uses his agility to distract the enemy while Captain Marvel blasts them with her powerful energy. They could also have some fun banter, like Spider - Man making a joke about how Captain Marvel can fly and he has to swing around.
There might be such fanfiction out there in the vast world of fan - created content, but it's not a common or officially recognized storyline. Fanfiction often explores wild and creative ideas that deviate from the main canon of the characters.
Another fanfiction concept could be a mentorship situation. Spider - Man looks up to Captain Marvel as a powerful and experienced hero. She could train him to better control his powers and also teach him how to handle the pressure of being a hero on a larger scale. This could involve some intense training sessions where Spider - Man has to push his limits, and Captain Marvel shares stories from her own experiences in the galaxy.
At first, they might be a bit wary of each other. Spider - Man is used to working on the streets of New York, while Captain Marvel is more of a cosmic hero. But as they face challenges together, they start to respect each other's abilities. Eventually, they could become good friends and rely on each other in future battles.
For Spider - Man, he might become more distrustful at first due to being forced into this situation. But as he realizes Captain Marvel is also a victim, he could start to open up and show his more collaborative side. Captain Marvel, on the other hand, might initially be frustrated by the lack of control but could develop more patience as she works with Spider - Man.
Well, their team - up could be amazing. Spider - Man's acrobatic skills and street - level smarts combined with Captain Marvel's cosmic powers would make for an unbeatable duo. They could face threats that range from alien invasions to super - villains trying to take over the city. Spider - Man could use his webs to create distractions or trap enemies while Captain Marvel blasts them with her energy powers.
In a fanfiction of their marriage, perhaps it starts with Spider - Man being in awe of Carol Danvers' abilities. She, on the other hand, is intrigued by his tenacity. They go on a series of missions together where they gradually fall in love. When they decide to get married, it's not without challenges. There could be villains who try to stop the wedding because they fear the combined power of the two heroes. But with the help of their friends, they overcome all obstacles and have a beautiful wedding, vowing to protect each other and the world always.
