Radar, the telepathic international policeman doesn't really seem to stand out at first glance. He seems like your typical generic Golden Age superhero...
However, his origins were much more interesting. Will Liberson, Executive Editor of Fawcett Comics (who you might recall from last week's Comic Book Legends Revealed), actually had Radar created as an offering to the United States Office of War Information (OWI) for propaganda purposes! He went to the organization in 1944 and suggested the comic would work well as anti-fascist propaganda for children. He had had them plot out a bunch of stories featuring the character.
Radar was a featured player in Master Comics from 1944 to 1948, all the while being clear to spread anti-fascism propaganda the whole time (even as Communism usurped Fascism as the most feared "ism" in the United States).
