Created by Marv Wolfman, George Perez and Jerry Ordway, Mobius/The Anti-Monitor made his first appearance in 1985's Crisis on Infinite Earths #2. The incredibly powerful villain served as one of the main antagonists for the event, and he's a forced to be reckoned with, having beaten some of the DC Universe's strongest heroes over the years.

At this time, many details about how the Arrowverse version of the event will play out remain unknown. However, Superman Returns actor Brandon Routh is set to reprise his role as the Man of Steel, playing the Kingdom Come version of his character. Routh will also play Ray Palmer/The Atom. Additionally, as Arrow is entering its final season, there's a good chance Stephen Amell's Oliver Queen won't make it through the event alive.
