give this man a shield

One possible reason could be a conflict in ideologies. Spider Man might believe in a more individualistic approach to justice, while Shield's methods could seem too bureaucratic or controlling to him.

Yes, Iron Man 1 did have the image of Captain America's shield.

Yes, he does. It's a significant moment in the comics.

His relationship with Black Widow could also be affected. Black Widow has a long history with Shield. Spider Man might view her with distrust, which could lead to some interesting and conflict - filled interactions in the fanfiction. He may not be as willing to team up with her as he would be in the normal Marvel universe.

Well, 'Shield - Bearing Spider - Man' is also a good one. It features Spider - Man using a shield that he creates himself using his scientific knowledge and some alien tech he comes across. The fanfiction focuses on how he tests and improves the shield, and how it becomes an integral part of his crime - fighting arsenal.

Power struggles can be a reason. Spider Man, being a solo hero with his own set of powers and moral code, might not agree with Shield's more bureaucratic and sometimes secretive ways of handling things, so they clash. For example, Shield might want to control Spider Man's actions, which he resists. This can lead to a fight. Also, there could be a villain manipulating events behind the scenes to make it seem like Spider Man is against Shield or vice versa.

Spider - Man himself is obviously a very popular character. His acrobatic fighting style and quick - witted personality make him a fan favorite. Then there's Agent Coulson, who is often seen as a mentor figure. His calm and collected nature in the face of danger is really appealing.

One interesting fanfiction could be where Spider - Man discovers a shield - like device that has ancient powers. It might start with him finding it during a battle in an old, abandoned building. The shield could have the ability to deflect not just physical attacks but also some of the more mystical threats he faces in the city.

There's a fanfiction called 'Spider - Shield Rivalry' where Spider Man is wrongly accused by Shield of a crime he didn't commit. This sets off a chain of events that results in some amazing fight sequences. It also delves into the moral dilemmas of both sides.

Another way is through character relationships. A Shield agent might be initially skeptical of Spider - Man, seeing him as an unregulated vigilante. But as they work together, they come to respect and trust each other. This evolution of their relationship can be a central theme in the fanfiction, with their combined efforts against villains being a by - product of their growing bond.
