I recently watched One Punch man which made me think about heroism, what a hero is and what it means. Saitama, and the top tier famous heroes in the story rarely risks anything. Their immense power just makes their actions an illusion of being heroic, theres rarely anything at stake for them, Saitama especially.
Mumen rider is an example of a true hero to me in that story, his only superpower being that he rides a bicycle, and he stands before certain destruction just to delay the monsters from hurting innocents for a few seconds. Risking everything.
By that definition, most superheroes, like the Avengers just look like power fantasies, does Spider-man or superman ever really risk anything substansial or acts in the face of certain destruction.
