Darkseid

The Lord of Apokolips. A powerful, god-like being who seeks to conquer Earth and ultimately obtain power over all life.

Superman and Jimmy Olsen first encounter Darkseid through the agency of his minions, including Morgan Edge II, in November 1970 when they battle the Mountain of Judgement alongside the Newsboy Legion (JO No.134: "The Mountain of Judgement").

In January 1971, Darkseid's servant Simyan notes that he is "stern, but he rewards his loyal and efficient servitors." Darkseid's own words, however, betray a personality that is less sanguine:

    Yes but who can deny the power of the other
    side?  Death can eclipse life!  A great
    lie can smash truth!  And the answer to a
    finely disciplined Superman is ... a chaotic
    fury of a thing --an uncontrollable organic
    murder machine!
