Omni-Menace

An alias employed by Superman in January 1965 when, after donning an "almost indestructible costume, which can be electrified," he posed as a superhuman villain from the distant past as part of his plan to defeat a trio of villains—perfect look-alikes for the ancient heroes Samson, Atlas, and Hercules—from an unidentified extradimensional "parallel world" (Act No. 320: "The Three Super-Enemies!").
