Watching the What if series now which are animations by Marvel studios. The concept allows an interesting dimension that the company have always had in their comic book franchise.

It allows their writers to take their main characters and story line in a different direction that would not be allowed.

So there is what if Agent Carter became Captain America, Black Panther became a Guardian of the Galaxy, Avengers Initiative died, Dr Strange became bad, Kilmonger saved Tony Stark. The episodes can be funny, sad or very dark.
