….but Superman doesn’t retire for eight years and have his legs become all decalcified. After which he puts on a knee brace. And has his decalcified Back broken by Bane. Which is repaired in prison with a rope. Which he then wrenches twice more trying to escape. But then climbs out of the prison/well and gets back to Gotham, and promptly gets stabbed by his not-girlfriend. And gets not-blown-up and not-irradiated in a nuke explosion. After which he disappears. And then shows up in a public place where any kid with a cell phone could photograph him
So… sure. You might discount Superman on the grounds of “but that could never happen in real life”…. but refer above.
