Darkseid. Leader of Apokolips, enemy of New Genesis, and perennial big-bad of the DC Universe.
First appearing in 1971 in Jack Kirby’s New Gods series, Darkseid has appeared as a Justice League antagonist in basically every form of media, most recently in the animated movie Justice League Dark: Apokolips War, but also in several TV shows and comics. While narrowly missing out on a live-action movie debut in Zack Snyder's Justice League (although possibly not with the Snyder Cut on the way) Ava DuVernay and Tom King's New Gods script reportedly features him as a character, so here's hoping we'll see him in the rocky flesh soon.
But despite the Lord of Apokolips' greatness, there are plenty of other characters that deserve as much if not more attention. The Justice League has a storied roster of villains to choose from, with many rivalling and even surpassing Darkseid as a threat. While his search for the Anti-Life Equation is compelling, it's time to explore the other enemies of the League, and hope they get their time in the pop-culture sun.
So, who's the over-used and rinsed-out mainstay of the Justice League's rogues gallery?
