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.
Thor is another popular Avenger in fanfiction. His god - like powers and his fish - out - - of - water moments on Earth are fun to explore. And from Agents of Shield, Fitz and Simmons are beloved for their scientific genius and their endearing friendship that often gets tested in different fan - made scenarios.
Another great storyline could be about the Agents of Shield having to deal with the aftermath of an Avengers - level battle. They might be in charge of cleaning up, helping the survivors, and trying to figure out how to prevent such destruction in the future. This could show a different side of the Agents of Shield, as they are often in the background but play a crucial role in the overall Marvel universe.
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.
Skye (Daisy Johnson) is also very popular. Her journey from a hacker to a powerful Inhuman is fascinating. Fanfiction often delves deeper into her powers and her role in both Shield and in relation to the Avengers. She has a complex personality which gives a lot of room for creative writing.
Another storyline might be a time - travel plot where the agents go back in time to prevent a major event that would have led to the downfall of the Avengers. They could encounter younger versions of the heroes and change the course of history. This would involve a lot of character development and exploring different timelines.
One interesting storyline could be a crossover where Agents of Shield agents have to team up with the Avengers to stop a powerful alien threat that neither group could handle alone. This would involve a lot of character interactions, like Coulson trying to give orders to Iron Man or Natasha Romanoff teaching some of the Shield agents her spy skills.
Definitely Coulson. He has such a rich backstory and his relationship with both the Agents of Shield and the Avengers (in an indirect way) is very interesting. His resurrection in Agents of Shield also provides a lot of potential for fanfiction. You could explore how he copes with being brought back to life and his new purpose.
One interesting story could be about how the Avengers react to a particular mission in Agents of Shield that goes wrong. Maybe they step in to help and there are some great character interactions between the two groups.
Maybe a virus is spreading that targets superhumans. The Avengers start getting affected one by one. The Agents of SHIELD, being more used to dealing with biological threats, step in. Daisy could use her quake powers to contain the virus in certain areas. May could train some of the Avengers in hand - to - hand combat techniques they might be lacking. And together, they search for the origin of the virus, which turns out to be an experiment gone wrong in a hidden SHIELD facility from the past. They then have to race against time to find a cure before all the superhumans are wiped out.
