Darkseid could very well be the most dangerous foe the Justice League of America have ever faced. He is the evil ruler of the planet Apokolips. For years Darkseid has tried to conquer the universe and rule over it, forcing everyone in the universe to bow to his will. With the help of his henchmen, Kalibak and DeSaad, Darkseid has become a dreaded figure all over the galaxy.
His powerful Omega Beams can even overwhelm Superman when used at full power!
