6) THE FALCON (but not Sam Wilson)
Here’s a weird one, from the files of MLJ Comics, the company that would become Archie: The star of a strip called ‘The Press Guardian’, he is only called Falcon in his first appearance. (That first appearance is in Pep Comics #1, along with the first bow of more noteworthy heroes The Comet and The Shield.) Later appearances have him in the mask/suit/hat combination, going by the nom de guerre of Press Guardian. Several online sources incorrectly list The Falcon and The Press Guardian to be two separate characters; it is also widely and falsely reported that his secret identity is Flash Calvert, a separate character in the same story.
In short, don’t trust random sites, trust me: I’ve read the original issue!
