Just an objective outsider tossing his two cents in the ring:  When I saw the expression "comic book hero" in the title, I immediately thought of a hero who came from a comic rather than one who would eventually find his way into comics.  (For example, the Three Musketeers have turned up in comic books but I wouldn't think of them as comic book heroes ala Superman or Batman, if that makes any sense.)  Not trying to fan any flames here, just sharing my own "mental reflex" at the expression "comic book hero."
I had that it mind. As I have noted, plenty of prose or other properties have made it into comic books.
