One idea for a Captain Marvel and Spider - Man fanfic could be that they team up to fight a common enemy from another dimension. Maybe a powerful alien force is trying to invade Earth, and their combined powers are needed to stop it. Captain Marvel with her energy - based powers and flight, and Spider - Man with his agility and web - slinging skills would make an awesome duo.
In fanfiction, Spider - Man can have some really cool crossovers in Marvel vs Capcom. He might team up with unexpected characters, like using his web - slinging skills to help a more melee - focused character reach distant enemies. His acrobatic fighting style would add a new dynamic to the battles.
In the 'Spider - Man Web of Shadows' story, Spider - Man is at the center. His love interest Mary Jane plays a significant role. Other characters include his fellow superheroes. For instance, Luke Cage, who has his own unique abilities and can be a powerful ally or an adversary depending on the situation. Wolverine also makes an appearance. His healing factor and his ferocious fighting style add an interesting dynamic to the story. There are also the villains who are either behind the symbiote invasion or are part of the chaos it causes.
A fanfiction could focus on Black Cat's backstory within the Web of Shadows context. Maybe she has a secret past connection to the symbiotes that is slowly revealed as she battles against them. This would add depth to her character and her role in the story.
In the context of Spider - Man: Web of Shadows' evil ending fanfiction, one interesting aspect could be the character development. If Spider - Man goes down the evil path, how do the other characters react? For example, Mary Jane might be horrified and try to bring him back to the good side. Also, villains might either team up with this new, evil Spider - Man or see him as a threat to their own plans.
