Steppenwolf (DC Extended Universe)

"No protectors here: no Lanterns, no Kryptonian. This world will fall — like all the others."

- Steppenwolf

Steppenwolf is the main antagonist of the 2017 superhero film Justice League. He is a Apokoliptian warlord who seeks to steal the three Mother Boxes on Earth for Apokolips. He is also the right-hand and uncle of Darkseid, and secretly desires to break free from his nephew's control. He is based on Steppenwolf from the original comics.

He is portrayed by Ciarán Hinds, who also portrayed Mance Rayder.

Early Life
Steppenwolf was born several millennia ago on the hellish planet of Apokolips. At some point, Steppenwolf became the herald of his nephew Darkseid, and would take over planets in his name, prevailing in every attempt. Eventually, after countless years of conquering and serving under Darkseid, Steppenwolf desired to free himself from his eternal servitude, although he was neither powerful nor foolish enough to try and oppose his master, and continued bitterly serving him.

Communion on Earth
In 2016, Lex Luthor broke into Scout Ship 0344 (intending to use it's Genesis Chamber to turn the body of General Zod into a Kryptonian abomination), he accessed the ship's database and made contact with Steppenwolf. Steppenwolf taught Luthor about the Mother Boxes, however, Lex was interrupted, breaking their contact.

Seeking the Mother Boxes
On Darkseid's orders, Steppenwolf was sent to Earth to collect the Mother Boxes on Earth, bringing a vast army of Parademons along with him.
