Since Doc Savage was created before Action Comics #1 hit the stands one could say that he was the “original” Superman (though there are some who feel that Popeye was the original Superman). The main writer of these pulp adventures, Lester Dent, described Doc Savage as manifesting “Christliness”. Doc had an oath, that went like this:

“Let me strive every moment of my life to make myself better and better, to the best of my ability, that all may profit by it. Let me think of the right and lend all my assistance to those who need it, with no regard for anything but justice. Let me take what comes with a smile, without loss of courage. Let me be considerate of my country, of my fellow citizens and my associates in everything I say and do. Let me do right to all, and wrong no man.”
