I wouldn't really call the Ghost in the Shell children androids, since they allegedly have the minds of human kids in them instead of being programmed bots. But that was also a question posed by the story - are they really the kids, or are they something else like a copy or an abomination?

Superheroes are just a thing that goes back through the legends and tall tales of humanity, like the stories of Hercules and the Greek pantheon etc. Marvel and DC corporations don't own that idea.
