Johnny Kirk

The son of Professor Morton Kirk, a noted astronomer who, approximately a decade ago, while Johnny was still an infant, spotted “a giant planet, plunging from outer space" on a collision course with Earth. Believing that a “cosmic collision” was inevitable and that ‘‘the end of the world’’ was at hand, Professor Kirk placed young Johnny inside “a space rocket he had recently perfected" and fired him off into outer space toward a hoped-for haven on a distant planet, much as Jor-El and Lara once launched the infant Superman into the interstellar void to save him from the death of Krypton.

However, the Earth was rescued from the impending cataclysm through the heroic intervention of the then teenaged Superman, but Professor Kirk, profoundly shaken by the shock of having needlessly exiled his son into space, died soon afterward, leaving behind him a document appointing Superman as his son’s legal guardian in the unlikely event the youngster ever succeeded in returning alive from space.

In September 1957, however, Johnny Kirk—now approximately twelve to fourteen years of age—did return, having survived since infancy on a far-distant "primeval planet,” at least in part because he had become endowed with super-powers identical to Superman’s when the rocket built by his father passed through “a peculiar cloud in space, pulsating with energy," a mysterious "cloud of cosmic energy," that somehow “increased his capabilities far beyond normal…!”

Determined to comply properly with Professor Kirk’s last request, Superman threw himself enthusiastically into the role of foster parent, proudly dubbing his young charge Superman Junior, and launching him on a rigorous training program designed to prepare him for the demanding role of his own junior partner in the father and son superhero team of Superman and Superman Junior.

Complications arose, however, when Superman’s powers began one by one to fade and vanish as the result of his having breathed in the noxious fumes of the ‘‘peculiar meteoric dust’’ clinging to the wreckage of Johnny Kirk’s rocket, an unearthly variety of “super-poison” that would in time render the Man of Steel as vulnerable as an ordinary earthman.

However, in spite of Superman's courageous effort to keep his dilemma a secret, Johnny became aware of Superman’s increasing disability and willingly sacrificed his own hopes for a superhero career by transferring his own super-powers into the Man of Steel's body with the aid of a special meteor whose unique properties enabled him to effect a permanent ‘‘transfusion of power" from his own body to Superman’s, albeit only at the expense of transforming the boy into an ordinary earth boy.
