The Avengers would likely have a range of reactions. Captain America would respect the Incredibles' sense of justice. And the Hulk might just be confused at first but then find it cool.
If the Avengers watched The Incredibles, it could be a very interesting scenario. The Hulk might get a bit jealous seeing Mr. Incredible's strength at first. Black Widow would notice how Mrs. Incredible manages to be a great mother and a superhero at the same time. Hawkeye would be interested in the archery skills of any character in the movie who might use a bow. And they all could learn something about teamwork from the family's dynamic in the movie.
I really like the fanfiction 'Incredible Avengers Alliance'. It focuses on the relationships between the characters. For example, it shows how Mr. Incredible and Captain America bond over their leadership qualities. It also has some amazing action scenes where the combined forces of both groups take on a huge threat.
Some Reddit communities dedicated to fanfiction might also be a good source. For example, r/FanFiction or subreddits related to The Incredibles or the Avengers. Members often share and discuss their favorite fanfictions, and you might discover some hidden gems of 'Incredibles Avengers' fanfiction there.
Well, perhaps the Infinity Stones somehow end up in the world of The Incredibles. This attracts the attention of both the Avengers and the Parr family. The two groups initially have some misunderstandings as they try to claim the Stones. But then they realize that a powerful new villain, created by the combined energy of the Stones, is emerging. So, they join forces. Dash's super - speed could be useful for quickly transporting the Stones, while Thor's lightning powers could help in battles against the villain's minions.
One common theme is teamwork. Since both the Avengers and the Incredibles are about groups of heroes, fanfics often explore how they work together. Another theme is power management. The different powers of the characters from both universes are often compared and contrasted.
Mr. Incredible and Hulk. Just think about it. They both have incredible strength, but they also have different personalities. Mr. Incredible is more family - oriented and used to working in a team with his family. Hulk is more of a lone force, but when they team up, their combined strength could be unstoppable. They could have a great dynamic, like Mr. Incredible trying to calm Hulk down when he gets too angry or Hulk teaching Mr. Incredible some new ways to use his strength in a more brute - force manner.
One interesting plotline could be the further exploration of the family's relationships. For example, how the kids deal with growing up with superpowers in a world that still has some prejudice against supers. Another could be the origin stories of the villains in more depth, like Syndrome. Maybe there could be a fanfic where he had a chance at redemption.
I like 'The Incredibles in the Avengers World'. It's a fanfic that shows how the Incredibles would adapt to the more complex and dangerous world of the Avengers. The author does a great job of showing the culture shock for the Incredibles. There's also 'Avengers Meet the Incredibly Strange' which is full of unexpected twists and turns as the two groups interact for the first time.
One idea could be that the Incredibles' superpowers are enhanced by the Avengers' technology. For example, Mr. Incredible could get a high - tech suit from Stark Industries that gives him even more strength and the ability to fly short distances. Another plot could involve the villains from both universes teaming up, forcing the combined heroes to work together in new ways. Maybe Syndrome teams up with Loki, and they create a device that can nullify superpowers, so the heroes have to find a way to stop it.
