Hi Morgana,
Thanks for the FDK!
Urgh! I know Doc Savage and his crew. Am I missing something?
Doc Savage was not one of the superheros I was thinking of, but we can add him. I was thinking specifically of comic book superheroes. Doc was a comic book hero for a short time, but he was primarily a pulp novel hero. That still leaves between 3 and 6 to guess.
If you read chapter 3 carefully there is an allusion to the origins of the comic book heroes.
