Justice League reportedly changes the comic book connection between Steppenwolf and the ruler of Apokolips, Darkseid.
“In Justice League, Batman and Wonder Woman, following Superman’s death in battling Doomsday, is intent on bringing together a team to take on Steppenwolf.
However, it seems that the New God’s live-action origin and connection to Darkseid may differ from his comic book roots.
This new menace is the nephew to Darkseid of Apokolips (presumably the big bad of the second JL adventure).
