Harley Hudson, aka the Firefly (not to be confused with the DC villain of the same name) if Archie's and MLJ's 4th Golden Age superhero, an entomologist and chemist. He discovers that insects can lift masses greater than their own weight not because of the square–cube law
but because of their ability to coordinate their muscles. He teaches
himself to coordinate his muscles as insects do and finds himself able
to perform amazing feats. He then dons a costume and calls himself the
Firefly.Thus, the Firefly, similar to the Black Hood,
another MLJ superhero, does not possess any real superpowers but is
merely a man possessing great physical and mental prowess due to his
natural abilities.
