King calls Superman his "White Whale" in the sense that it's the project he most aspires to do and do right. It's no wonder that he sprinkles in so much Superman-like stuff into his work. And the idea that Sanctuary is both built by Kryptonian tech, its robots are modeled after Ma, Pa, and Lana, and the masks are direct homages to the oldest Superman shield are all pretty clear signs of his love for the character.
