Superman is an immigrant Jew created by two Jewish men who were watching things get worse in Europe while quotas for Jews were being cut lower and lower by immigration laws because of the eugenics movement around the world from the turn of the century and into the 20s and 30s.
Captain America was Jewish creators making a superhero who looked like the Nazi Aryan ideal but had the heart of a real American: a sick, poor, Irish immigrant kid from Brooklyn. He didn't punch Hitler on the chin on the cover of the first issue by accident.
Fantastic Four? Created by a Jew, who gave three of the characters super neat superpowers, and the Jewish character the inability to hide his powers at all. And then showed people reacting in horrified ways to Ben's appearance like, perhaps, he'd seen happen to his family and friends and neighbors because they looked "too" Jewish.
The list goes on (Magneto being the next obvious point). If you are reading/watching/taking in superhero media from Marvel or DC (Jack Kirby especially), you are looking at a character created by Jews who put their own identities into those characters.
