After Savage stole the Warworld and issued a warning not to attack Earth, he headed to Apokolips where Darkseid was waiting for him. Darkseid greeted Savage as an equal, giving him a vigorous handshake as the neanderthal reassured him that it was "business as usual".
Darkseid is the ruler of the planet Apokolips, the antithesis of New Genesis. He made his first appearance in the seventies as the chief antagonist of writer Jack Kirby's Fourth World epic; over the succeeding years, he has become a prominent foe of Superman and to the Justice League. Darkseid's ultimate goal is to gain control of the Anti-Life Equation, which would allow its possessor to control the cosmos.
This is Darkseid's fifth animated appearance. He appeared in the later seasons of Super Friends, the DC Animated Universe (Superman: The Animated Series, Justice League and Justice League Unlimited), Batman: The Brave and the Bold and Superman/Batman: Apocalypse.
