Rolling Stone has one weird story: The Legend of Master Legend. It’s about people who think they are superheroes, right down to donning costumes and calling their run-down suburban ranch house a secret lair. These people are deluded, all right, but they seem mostly harmless, and the story is written in a tone that doesn’t mock them.
One surprising piece of information is that there are enough of these people around that there are actually hero supply houses for them. One is called Hero Gear, which will make your costume for you (no mass-produced items here, since every super-hero is unique), and ProfessorWidget, who will make all your special gadgets for you.
