The Fox was an athletic costumed character without super powers. Unless you count having a cool costume containing a hidden camera for taking newspaper pictures of bad guys and evildoers. He was invented by writer Joe Blair and artist Irwin Hasen for Blue-Ribbon Comics, an MLJ anthology comic. The Fox, undoubtedly because of that cool costume, has been revived a few times.
Irwin Hasen went from comic books to the long-running newspaper comic strip, Dondi. Hasen died in 2015 at age 96.
This story, which comes from MLJ’s Blue-Ribbon Comics #9 (1941) is the Fox’s fifth appearance. After a time in the forties MLJ superheroes gave way to the inevitable, and were replaced by the teenage antics of Archie and his pals and gals.
