One interesting plot idea could be a crossover where Spider - Man has to team up with the Agents of Shield to stop a new super - villain who has the ability to control technology across the globe. This would force Spider - Man to use his street - level skills along with the high - tech resources of the Agents of Shield.
One idea could be that the Agents of Shield discover Peter Parker's identity as Spider - Man early on. They could then offer him some special training or equipment. For example, they might give him a high - tech suit upgrade that has features similar to the ones in the Agents of Shield technology. This would add a new dimension to his crime - fighting in Spider - Man Homecoming.
A new character could be an alien who crash - lands on Earth and has a connection to the technology that the Agents of Shield are researching. Spider - Man would be intrigued by this alien's abilities and the Agents of Shield would want to study it. This could lead to a story where they have to protect the alien from other forces who want to use it for their own evil purposes.
One unique interaction could be that Spider - Man's sense of humor and youthfulness could lighten up the often - serious atmosphere among the Agents of Shield. He could crack jokes during a mission, at first annoying some of the agents but then gradually winning them over. And in return, the Agents could offer him some guidance on how to be more strategic in his superhero work, rather than just relying on his instincts all the time.
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.
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.
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.
One possible fanfiction idea about Skye could be a 'what - if' scenario. What if Skye had joined a different organization instead of S.H.I.E.L.D.? How would her character develop differently? This could lead to a whole new set of adventures and relationships, perhaps even changing her moral compass depending on the nature of the new organization.
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.
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.
