The story could develop in a very complex way. At first, there might be a power struggle. The Avengers are high - profile heroes, while Agents of SHIELD are more of the behind - the - scenes type. But as the plot unfolds, they would realize their similarities. Both groups are committed to protecting the world. They could start to work together, with each member finding their own role. For example, Ward (assuming he's redeemed in the fanfiction) could team up with Hawkeye for some stealth missions, and Coulson could strategize with Captain America. As they face bigger and bigger threats together, their relationship would grow stronger, and the story would be about their journey from mistrust to a united front.
In this fanfiction scenario, the development might involve the sharing of knowledge. The Agents of SHIELD have a lot of information about hidden threats and secret organizations. The Avengers, on the other hand, have experience dealing with powerful cosmic entities. They could exchange this knowledge, which would help them both. For instance, the Agents of SHIELD could tell the Avengers about a hidden Hydra base, and the Avengers could share their knowledge of an upcoming alien threat. This would lead to joint missions and the forging of new friendships and alliances within the story.
The story could start with a call for help. Maybe an enemy that the Agents of SHIELD can't handle alone is causing havoc. So they reach out to the Avengers. Then there would be a period of getting to know each other. Some characters might not trust each other at first. But as they face challenges together, like fighting a powerful super - villain, they start to bond.
Well, Tony Stark would probably be quite cocky around the Agents of Shield at first. He might make sarcastic remarks about their technology compared to his. But then he'd realize they have some unique skills and knowledge. Steve Rogers, on the other hand, would be more respectful and interested in their mission. He'd see them as comrades in the fight against evil. Natasha Romanoff might find some kindred spirits among the female agents of Shield like May. They could share their combat experiences and spy techniques.
Well, there could be a lot of chaos and cooperation. Maybe the Agents of SHIELD with their unique skills in espionage and handling strange threats could offer some fresh perspectives to the Avengers. For example, Fitz could help Tony Stark with some new tech ideas, while Coulson's leadership could guide the Avengers in a more covert operation.
The story could develop from a misunderstanding. Sigyn is seen doing something strange on Earth, and the Avengers think she's up to no good. They try to stop her. But as they engage in a fight, they realize she's not as bad as they thought. Sigyn then explains her situation, perhaps she's looking for something that was lost on Earth. The Avengers offer to help her. Along the way, they encounter various enemies and Sigyn's unique powers and knowledge help them out. This leads to a deeper relationship between Sigyn and the Avengers as they continue their adventures together.
Well, the plot could involve the Agents of Shield having to team up with the Avengers to stop a common enemy. Maybe a powerful alien threat or a super - powered villain that neither group can handle alone. The Agents could bring their espionage and covert ops skills, while the Avengers contribute their raw power.
Definitely Coulson and Iron Man. Coulson is a big fan of Iron Man in the show, and seeing them interact would be great. Iron Man's sarcasm and Coulson's more straight - laced nature would create some really interesting banter.
Tony Stark would probably be very vocal about his thoughts. He might make sarcastic remarks about some of the Agents of Shield's tech that he thinks is inferior to his own. Steve Rogers, on the other hand, would be more focused on the moral aspects of what the Agents are doing.
One idea could be that the Avengers need the Agents of Shield's help to track down a new, powerful and elusive villain who has technology that can disrupt the Avengers' powers. The Agents use their espionage skills to gather intel while the Avengers provide the muscle when it comes to confronting the bad guy.
The plot could start with a mysterious event that links the two worlds. Maybe a powerful artifact from the Agents of Shield universe ends up in the hands of Snake Eyes' enemies. This would draw the agents in to retrieve it and they would meet Snake Eyes. As they work together, they discover that there are deeper forces at work, like a secret organization that wants to use the artifact to gain power over both their worlds.
At first, it might be a relationship of mutual suspicion. The Agents of Shield are used to dealing with threats within a certain framework, and Percy with his magic powers and connection to the Greek gods would be something completely new. But as they face common enemies, like a powerful demigod - turned - villain or a group trying to use Greek magic for evil, they would start to trust each other more.
In Avengers fanfiction, Phil Coulson is often considered one of the best Shield agents. He is highly dedicated, intelligent, and has a deep understanding of the Avengers. Another great one could be Maria Hill. She is tough, strategic, and can handle high - pressure situations well. And then there's Clint Barton, who combines his excellent archery skills with his Shield agent training.
