"Detective Denton is called `Doc' by his fellow police officers because he is also a master surgeon."
The Phantom of the Underworld doesn't have any powers, but he is clever and uses his wits and skills as a detective and surgeon against the criminals.
Note: Sorry I don't have more to say about Doc Denton, but, well,
sometimes these Golden Age characters are really quite dull, and there's
just not that much to say about them, y'know?
