Disclaimer: Surprisingly, I couldn't get a good Google result for this one. And the only Marvel Universe knowledge I have is from the movies. So forgive me if this is a dumb question.
Most all of the Marvel superhero movies that I have seen have some sort of villain. And a lot of them want to destroy the city, world, universe, etc. But the other villains must live in the same city, world, or universe and likely don't want to be destroyed (or they want to destroy it themselves). So I would imagine that it would be in a villains interest to stop other villains' plans.
For example, I just watched Guardians of The Galaxy Vol. 2. And I think that villain was trying to do some sort of takeover of all of the planets in the universe. This plan must have affected some other Marvel villains. So why didn't any of them try to stop it?
Is villain interaction ever addressed in the movies? Or is it just ignored because that would make it too complicated?
