Kulak originated in the realm of Brztal, tho whether this is a planet or otherdimensional realm is not clear.  At some point,        he was entombed by an ancient, but unknown civilization on Earth.  Kulak placed a curse on the tomb, vowing to annihilate any civilization that profaned it.  When it was discovered in the lae 1930’s on Earth-Two, a parchment was recovered that proclaimed Kulak’s warning. When it was taken to museum, Kulak appeared to retrieve it, injuring a museum guard.  As Jim Corrigan arrived to hear the case, he realized there were otherworldly aspects to it and summoned the Spectre.  Kulak immediately appeared to challenge the Spectre and immobilized him. 

Setting forth to keep his promise, Kulak summoned up waves of catastrophes, beginning a whispering death that caused raging hatred in humans, driving them to attack each other.  This was dispelled by the liberated Spectre but followed by waves of locusts which the Spectre translocated into space. Finally, Kulak causing the oceans of the world to rise and flood civilization.  The Spectre attacked and Kulak uttered an incantation that began to dissolve the Spectre’s form.  Calling on the Almighty, the Spectre was given the Ring of Life which Kulak could not abide.  The sorcerer fled but not before summoning the undead legions of Brztal, who the Spectre had to systematically destroy to resume pursuit.  Having somehow lost the Ring of Life, the Spectre leaped at Kulak anyway, interrupting an incantation that Kulak then lost control of, seemingly consuming the sorcerer.  With Kulak apparently destroyed, the oceans returned to their beds and the Spectre returned to the form of Jim Corrigian (All-Star Comics #2).
